I want to programmatically access the Fields collection in the ObjectDataSource object of my Telerik report.
I did notice in the design portion of the Telerik report you can access the fields collection
in the Value by using the Edit Expression window.
Example:
= Fields.MyFieldName
How would I accomplish this task using C# code in the report code behind file?
I had the same problem. This is how I solved it, although I believe there should be an easier way.
First I created a method for the details section itemdatabinding:
private void detail_ItemDataBinding(object sender, EventArgs e)
{
Telerik.Reporting.Processing.DetailSection section = (sender as Telerik.Reporting.Processing.DetailSection);
object id = section.DataObject["Data Field You want to access"];
Variable Name = id.ToString();
}
You can now use that variable anywhere in your codebehind.
Note: The Data Field must appear in your detail section. In my case I did not need it to show, so I just made 'Visible=false'.
This worked for me.
Bind Data to your own data to your variables
string ItemCode = "a";
string ItemDesc = "aa"
Then bind it to the data source
var Output = new
{
ItemCode = a.ItemCode,
ItemDesc = a.ItemDesc,
};
this.DataSource = Output;
All these are in code behind. Then move to design portion and modify your text-box as shown below.
= Fields.ItemCode
= Fields.ItemDesc

I am reading data from the ActivityPointer entity in Dynamics 365 via the API and I want to link the activitytypecode field value to the activitypointer_activitytypecode global option set, which I believe is the correct one. However the values don't seem to match. In the ActivityPointer.activitytypecode field I have values such as:
phonecall
bulkoperation
email
appointment
task
But those values don't appear in the option set definition, using this query: GlobalOptionSetDefinitions(Name='activitypointer_activitytypecode')
The option set has the code values (e.g. 4202 for Email) and the different descriptions in all languages, but nothing matches back to the values on ActivityPointer
Optionset is just key value pairs (4202: Email and so on), If you want to get the formatted text value of optionset (Email, Fax, etc) from your web api query results - then you have to use activitytypecode#OData.Community.Display.V1.FormattedValue to get it. Read more
I recommend this article for complete understanding of CRM activities.
If you are looking for the code integer value in your resultset, that seems to be an issue and the result is not the expected one - old SO thread
The problem is that if you are reading activitytypecode in code, then you will know that you get a string value. This is the logical name of the activity entity, e.g. "email", "phonecall" etc.
If you look at the definition of activitytypecode in Power Apps then it shows it as "Entity name" (i.e. text) but using the classic solution editor it shows as the global activitypointer_activitytypecode option set, which contains values for "Email", "Phone Call" etc.
I am sure that there should be a simple way of converting from activitytypecode (i.e. entity name) to activitypointer_activitytypecode (i.e. option set), but I've yet to find it.
What I am doing is retrieving the global activitypointer_activitytypecode option set, so I have access to all of the text values. Then retrieve details about the entity indicated by activitytypecode, specifically what is of interesting is the display name. Then loop through the option set looking for a case-insensitive match on display name.
This is my C# code:
public int? GetActivityType(IOrganizationService service, string activityTypeCode)
{
// Get all activity types.
var optionSetRequest = new RetrieveOptionSetRequest()
{
Name = "activitypointer_activitytypecode"
};
var optionSetResponse = (RetrieveOptionSetResponse)service.Execute(optionSetRequest);
var optionSetMetadata = (OptionSetMetadata)optionSetResponse.OptionSetMetadata;
var optionValues = new Dictionary<string, int?>(StringComparer.OrdinalIgnoreCase);
foreach (var option in optionSetMetadata.Options)
{
foreach (var optionLabel in option.Label.LocalizedLabels)
{
optionValues[optionLabel.Label] = option.Value;
}
}
// Get the display name for the activity.
var retrieveEntityRequest = new RetrieveEntityRequest
{
EntityFilters = EntityFilters.Entity,
LogicalName = activityTypeCode
};
var retrieveEntityResponse = (RetrieveEntityResponse)service.Execute(retrieveEntityRequest);
LocalizedLabelCollection entityLabels = retrieveEntityResponse.EntityMetadata.DisplayName.LocalizedLabels;
// Look up the display name in the option set values.
foreach (var entityLabel in entityLabels)
{
if (optionValues.TryGetValue(entityLabel.Label, out int? value))
{
return (Schema.GlobalOptionSet.ActivityType?)value;
}
}
// If we get here then we've failed.
return null;
}
That is making two API calls, so best avoided in any situations where performance might be an issue. I'm not saying the code is perfect, but it hasn't let me down yet. Even so, I would recommend making do with the logical names provided by activitytypecode if you can.
I have a use case where I have created a view object that contains 3 values namely LOC_CODE, LOC_DESC, CITY_DESC. Now in my ADF form I would like to display all 3 values in such a way so that user would have a provision to select LOC_CODE From Popup(LOV) and rest two fileds LOC_DESC & CITY_DESC should be changed accordingly. Currently the popup shows all 3 values but when I select the row and click on OK button it only fills the LOC_CODE in 1 textbox.
Below is the scenario of the same:
Got the solution. Just need to add a textbox or drag and drop near respective field and bind it with required binding object. For e.g. in this case LOC_DESC & CITY_DESC is available in my data control as DefLoc & DefCity that contains SQL to fetch respective description value. Now I need to drag and drop DefLoc & DefCity and binding is automatically done or just check binding in value.
you have to add valuechangelistener to location code. set autosubmit true.
now in backing bean use following code:
public void valuechangelistener(ValueChangeEvent valueChangeEvent) {
valueChangeEvent.getComponent().processUpdates(FacesContext.getCurrentInstance());
BindingContext bctx = BindingContext.getCurrent();
BindingContainer bindings = bctx.getCurrentBindingsEntry();
JUCtrlListBinding list = (JUCtrlListBinding)bindings.get("LOC_CODE");
String selectedValue = (String)list.getAttributeValue();
list.getListIterBinding().setCurrentRowWithKeyValue(selectedValue);
Row currRow = list.getListIterBinding().getCurrentRow();
if (currRow != null) {
bndloc_desc.setValue(currRow.getAttribute("LOC_DESC"));
bndcity_desc.setValue(currRow.getAttribute("CITY_DESC"));
}
}
now set partial trigger to both location desc and city desc with id of LOC_CODE.
After doing this you will get your desired result.
update after implementing it.
In my case JDeveloper 12.2.1.3.0
public void valueChangeListener(ValueChangeEvent valueChangeEvent) {
BindingContext bctx = BindingContext.getCurrent();
BindingContainer bindings = bctx.getCurrentBindingsEntry();
JUCtrlListBinding list = (JUCtrlListBinding) bindings.get("YourBindingforLOV");
String selectedValue = (String) valueChangeEvent.getNewValue();
list.getListIterBinding().setCurrentRowWithKeyValue(selectedValue);
Row currRow = list.getListIterBinding().getCurrentRow();
if (currRow != null) {
String s = (String) currRow.getAttribute("YourAttributeName");
}
}
I am having trouble that RadFilter is not detecting the columns correctly. I bind my RadGrid through code in Asp like:
RadGrid1.DataSource = myDataSource;
RadGrid.DataBind();
RadFilter is only binding those columns which are bind through and ignoring those who are in . Is this a known issue? as I didn't see any thread talking about this problem. Waiting for help immediately.
Regards,
Wasim.
If I am understanding you correctly, you need to add FilterFieldEditors to the RadFilter for any field that is not represented in the DataSource for the grid.
You can add filters dynamically with the following code.
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
if (!IsPostBack)
{
var fieldName = "myDynamicFilterField";
var friendlyName = "Friendly Dynamic Field";
var newTextFieldEditor = new RadFilterTextFieldEditor();
filter.FieldEditors.Add(newTextFieldEditor);
newTextFieldEditor.FieldName = fieldName; // name filter will used for filter exressions
newTextFieldEditor.DisplayName = friendlyName; // name use will see when they selected a field to filter
// ** Repeat for all dynamic fields **
}
}
I was able to get a working version using auto generated columns and custom added columns, but ran into many other problems. I ended up just dynamically creating all the filter fields (as shown above) from the data source and applying the filter expression to the grid.
I'm using Visual Studio 2010 and i'm developing a windows form. Right now I'm using a data grid view and i want to write some functions that would allow you to automaticlly edit the datagrid by just changing the text in the Datagrid view. Right now, I am able to get the actual value but I need the value of the column in order to use it as a parameter when i use ADO.net here's what my code looks like now
private void dgv_DataLookup_CellValueChanged(object sender, DataGridViewCellEventArgs e)
{
DialogResult dr;
dr = MessageBox.Show("Are you sure you want to edit this field?", "Edit Cell", MessageBoxButtons.YesNo);
if (dr == DialogResult.Yes)
{
DataGridViewCell editItemCell = dgv_DataLookup[dgv_DataLookup.CurrentCell.RowIndex, dgv_DataLookup.CurrentCell.ColumnIndex];
string editItem = editItemCell.Value.ToString();
}
}
this here gets me the value of the current cell that is currently selected. I tried doing something like this
DataGridViewColumns columnCells = dgv_DataLookup.CurrentCell.ColumnIndex.Value.ToString()... something that would represent this but actual code. thanks!
According to what I understand you want to edit the value within a field, you can choose the value in this way.
private void button2_Click(object sender, EventArgs e)
{
if (MessageBox.Show("Are you sure you want to edit this field?",Application.ProductName.ToString(),MessageBoxButtons.YesNo)== DialogResult.Yes)
{
string editItem = this.dataGridView1.Rows[this.dataGridView1.CurrentRow.Index].Cells["NameField"].Value.ToString();
}
}

The functionality I am trying to use is:
- Create a ObjectDataSource for selection and updating controls on a web page (User Control).
- Use the DataObjectTypeName to have an object created that would send the data to an UpdateMethod.
- Before the values are populated in the DataObjectTypeName’s object, I would like to pre-populate the object so the unused items in the class are not defaulted to zeros and empty strings without me knowing whether the zero or default string was set by the user or by the application.
I cannot find a way to pre-populate the values (this was an issue back in 2006 with framework 2.0). One might ask “Why would anyone need to pre-populate the object?”. The simple answer is: I want to be able to randomly place controls on different User Controls and not have to be concerned with which UpdateMethod needs to handle which fields of an object.
For Example, let’s say I have a class (that reflects a SQL Table) that includes the fields: FirstName, LastName, Address, City, State, Zip. I may want to give the user the option to change the FirstName and LastName and not even see the Address, City, State, Zip (or vice-versa). I do not want to create two UpdateMethods where one handled FirstName and LastName and the other method handles the other fields. I am working with a Class of some 40+ columns from multiple tables and I may want some fields on one screen and not another and decide later to change those fields from one screen to another (which breaks my UpdateMethods without me knowing).
I hope I explained my issue well enough.
Thanks
This is hardly a solution to the problem, but it's my best stab at it.
I have a GridView with its DataSourceID set to an ObjectDataSource.
Whenever a row is updated, I want the property values in the object to be selectively updated - that is - only updated if they appear as columns in the GridView.
I've created the following extension:
public static class GridViewExtensions
{
public static void EnableLimitUpdateToGridViewColumns(this GridView gridView)
{
_gridView = gridView;
if (_gridView.DataSourceObject != null)
{
((ObjectDataSource)_gridView.DataSourceObject)
.Updating += new ObjectDataSourceMethodEventHandler(objectDataSource_Updating);
}
}
private static GridView _gridView;
private static void objectDataSource_Updating(object sender, ObjectDataSourceMethodEventArgs e)
{
var newObject = ((object)e.InputParameters[0]);
var oldObjects = ((ObjectDataSource)_gridView.DataSourceObject).Select().Cast<object>();
Type type = oldObjects.First().GetType();
object oldObject = null;
foreach (var obj in oldObjects)
{
if (type.GetProperty(_gridView.DataKeyNames.First()).GetValue(obj, null).ToString() ==
type.GetProperty(_gridView.DataKeyNames.First()).GetValue(newObject, null).ToString())
{
oldObject = obj;
break;
}
}
if (oldObject == null) return;
var dynamicColumns = _gridView.Columns.OfType<DynamicField>();
foreach (var property in type.GetProperties())
{
if (dynamicColumns.Where(c => c.DataField == property.Name).Count() == 0)
{
property.SetValue(newObject, property.GetValue(oldObject, null), null);
}
}
}
}
And in the Page_Init event of my page, I apply it to the GridView, like so:
protected void Page_Init()
{
GridView1.EnableLimitUpdateToGridViewColumns();
}
This is working well for me at the moment.
You could probably apply similar logic to other controls, e.g. ListView or DetailsView.
I'm currently scratching my head to think of a way this can be done in a rendering-agnostic manner - i.e. without having to know about the rendering control being used.
I hope this ends up as a normal feature of the GridView or ObjectDataSource control rather than having to hack it.
