If my CustomerName FieldName equals to "MyCustomer" , i want to hide editing for that row.
If customername == "MyCustomer , hide column editing.
How can i hide column editing according to "MyCustomer"?
settings.Columns.Add(s =>
{
s.FieldName = "CustomerName";
s.Caption = "Customer";
s.Name = "CustomerColumn";
s.ColumnType = MVCxGridViewColumnType.ComboBox;
var comboBoxProperties = s.PropertiesEdit as ComboBoxProperties;
comboBoxProperties.DataSource =Model.CustomerList;
comboBoxProperties.TextField = "Customer_Name";
comboBoxProperties.ValueField = "Customer_Id";
comboBoxProperties.ValueType = typeof(int);
comboBoxProperties.ClientInstanceName = "CustomerColumn";
});
Any help will be appreaciated with points.
settings.CommandButtonInitialize = (s, e) => {
if (e.ButtonType == ColumnCommandButtonType.Edit) {
MVCxGridView g = s as MVCxGridView;
var value = (int)g.GetRowValues(e.VisibleIndex, "RowFieldName"); //use a correct field name and cast a resultant value to a correct value type
e.Visible = value > 10; // for example, only
}
};
Fortunately , i have myself.I found a solution.
It works.Hope this helps who has the same problem in the future.

I want to create a recipe page with 3 different checkbox groups for different filters.
Currently, I have 1 checkbox group and linked it to a repeater.
Could anyone assist in guiding me on how to add 2 more checkbox groups to the repeater?
I went digging online but have yet to find a solution
import wixData from 'wix-data';
const databaseName = 'Recipes1';
const databaseField = 'tags';
$w.onReady(function() {
$w('#checkboxGroup1').onChange((event) => {
const selectedBox = $w('#checkboxGroup1').value;
addItemstoRepeater(selectedBox);
})
});
function addItemstoRepeater(selectedOption = []) {
let dataQuery = wixData.query(databaseName);
if (selectedOption.length > 0) {
dataQuery = dataQuery.hasSome(databaseField, selectedOption);
}
dataQuery
.find()
.then(results => {
const filtereditemsReady = results.items;
$w('#repeater1').data = filtereditemsReady;
})
}
What you're doing is a data query to fetch the items according to user selection.
In order to build a filter you need to use a dataset, connect the dataset to your repeater or table. View a filter example here, it shows you how to filter a dataset using multiple selections.
From my perspective, filter function for 3 checkbox groups should be like below
let checkbox1;
let checkbox2;
let checkbox3;
const filter = (ck1, ck2, ck3) => {
if(checkbox1 !== ck1 || checkbox2 !== ck2 || checkbox3 !== ck3) {
let newFilter = wixData.filter();
if(ck1)
newFilter = newFilter.hasSome('fieldKey1', ck1);
if(ck2)
newFilter = newFilter.hasSome('fieldKey2', ck2);
if(ck3)
newFilter = newFilter.hasSome('fieldKey3', ck3);
$w("#datasetId").setFilter(newFilter);
setVariables(ck1, ck2, ck3);
}
}
const setVariables = (ck1, ck2, ck3) => {
checkbox1 = ck1;
checkbox2 = ck2;
checkbox3 = ck3;
}
You will need to study the example to adapt to code according to your needs.
With this command I search all the items of a url where he looks for 10 items, now I need with this command to select only the item from the fifth position,
Returning only one item, how can I do this using the command below, what changes should I make
private async Task<List<FeedItem>> ParseFeed(string rss)
{
return await Task.Run(() =>
{
var xdoc = XDocument.Parse(rss);
var id = 0;
return (from item in xdoc.Descendants("item")
let enclosure = item.Element("enclosure")
where enclosure != null
select new FeedItem
{
Title = (string)item.Element("title"),
Description = (string)item.Element("description"),
Link = (string)item.Element("link"),
PublishDate = DateTime.Parse((string)item.Element("pubDate")).ToUniversalTime().ToString("dd/MM/yyyy HH:mm:ss"),
Category = (string)item.Element("category"),
Mp3Url = (string)enclosure.Attribute("url"),
Image = (string)enclosure.Attribute("url"),
Color_category =Convert.ToString(int.Parse((string)item.Element("color")), 16).PadLeft(6, '0'),
Id = id++
}).ToList();
});
}
Use Skip() and Take()
return (from item in xdoc.Descendants("item")
...
}).Skip(4).Take(1).ToList();
Hello I'm trying to copy the following linq results to a datatable. The only examples I see of copytodatatable is using the query format, and not the extension methods. Wondering if anyone knows how to use it with the extension methods (I've tried casting the results to IEnumerable datarow but it didn't work).
DataTable dtItemPricingBreakDown =
SiteHelper.getItemPricingBreakDown(CustomerId,
PriceBookID,
deliveryZip,
dtItems,
db,
departmentId);
dtItemPricingBreakDown.AsEnumerable()
.GroupBy(i => new {
sku = i.Field<string>("sku"),
deptid = i.Field<int>("department_id")
})
.Select(group => new
{
sku = group.Key.sku,
deptid = group.Key.deptid,
cnt = group.Count()
});
Update
Better late than never, sorry for the delay in response. My actual issue appears to be for both the query syntax and the extension methods.
Something like this works according to msdn
(http://msdn.microsoft.com/en-us/library/bb386921(v=vs.110).aspx):
// Fill the DataSet.
DataSet ds = new DataSet();
ds.Locale = CultureInfo.InvariantCulture;
FillDataSet(ds);
DataTable orders = ds.Tables["SalesOrderHeader"];
DataTable details = ds.Tables["SalesOrderDetail"];
var query =
from order in orders.AsEnumerable()
join detail in details.AsEnumerable() on order.Field<int>("SalesOrderID") equals detail.Field<int>("SalesOrderID")
where order.Field<bool>("OnlineOrderFlag") == true
&& order.Field<DateTime>("OrderDate").Month == 8
select new
{
SalesOrderID = order.Field<int>("SalesOrderID"),
SalesOrderDetailID = detail.Field<int>("SalesOrderDetailID"),
OrderDate = order.Field<DateTime>("OrderDate"),
ProductID = detail.Field<int>("ProductID")
};
DataTable orderTable = query.CopyToDataTable();
But when I try this...
var query = from exx in dtItemPricingBreakDown.AsEnumerable()
group exx by new { sku = exx.Field<string>("sku"), companyId = exx.Field<int>("department_id") } into grp
select new { sku = grp.Key.sku, DepartmentID = grp.Key.companyId, Cnt = grp.Count() };
DataTable dt3 = query.CopyToDataTable();
I get this exception: "No implicit reference conversion from anonymoustype1 to system.data.datarow". I've tried doing what they did with the dataset in the msdn example as well and I still get the error. Extension method wise I was trying something like this...and still got the same exception.
DataTable dt3 = dtItemPricingBreakDown.AsEnumerable().GroupBy(i => new
{
sku = i.Field<string>("sku"),
deptid = i.Field<int>("department_id")
}).Select(group => new
{
sku = group.Key.sku,
DepartmentID = group.Key.deptid,
cnt = group.Count()
}).Cast<DataRow>().CopyToDataTable();
How do I obtain the selected row value for a hidden column in a Telerik RadGridView? The column is hidden on the aspx page and I would like to retrieve the value on the client side (JavaScript).
Essentially, I want to display a name in the grid view and be able to retrieve a value from the hidden field "ID" to bring up an edit form.
Here is an example of how I'm hiding the RadGridView column.
code sample:
onKeyPressEvent(sender, args) {
var variable = function (e) {
e = e || window.event;
if (e.keyCode == 13) {
var PartyID = args.getDataKeyValue("PARTY_ID");
var oManager = '<%=winMgr.ClientID %>';
var oManager = window.radopen("AttorneyEdit.aspx?PARTY_ID=" + PartyID, null);
oManager.setSize(1000, 530);
//Width, Height oManager.center();
} else { return true;
}
}
theForm.onkeypress = variable
}
Thanks for your help...
maybe you're going the wrong way. There is a property called "ClientDataKeyNames" on the mastertableview. You can add several key separated by a comma in this property. Then you'll be able to get your value without adding an extra column.
You should do something like this:
function onKeyPressEvent(sender, args) {
if (args.get_keyCode() == 13) {
var dataItem=sender.get_selectedItems()[0];
var PartyID = dataItem.getDataKeyValue("PARTY_ID");
var oManager = '<%=winMgr.ClientID %>';
var oManager = window.radopen("AttorneyEdit.aspx?PARTY_ID=" + PartyID, null);
oManager.setSize(1000, 530);
//Width, Height oManager.center();
}
else {
return true;
}
}
good luck
I need to return a single instance of my viewmodel class from my repository in order to feed this into a strongly-typed view
In my repository, this works fine for a collection of viewmodel instances:
IEnumerable<PAWeb.Domain.Entities.Section> ISectionsRepository.GetSectionsByArea(int AreaId)
{
var _sections = from s in DataContext.Sections where s.AreaId == AreaId orderby s.Ordinal ascending select s;
return _sections.Select(x => new PAWeb.Domain.Entities.Section()
{
SectionId = x.SectionId,
Title = x.Title,
UrlTitle = x.UrlTitle,
NavTitle = x.NavTitle,
AreaId = x.AreaId,
Ordinal = x.Ordinal
}
);
}
But when I attempt to obtain a single entity, like this:
public PAWeb.Domain.Entities.Section GetSection(int SectionId)
{
var _section = from s in DataContext.Sections where s.SectionId == SectionId select s;
return _section.Select(x => new PAWeb.Domain.Entities.Section()
{
SectionId = x.SectionId,
Title = x.Title,
UrlTitle = x.UrlTitle,
NavTitle = x.NavTitle,
AreaId = x.AreaId,
Ordinal = x.Ordinal
}
);
}
I get
Error 1 Cannot implicitly convert type
'System.Linq.IQueryable<PAWeb.Domain.Entities.Section>' to
'PAWeb.Domain.Entities.Section'. An explicit conversion exists
(are you missing a cast?)"
This has got to be simple, but I'm new to c#, and I can't figure out the casting. I tried (PAWeb.Domain.Entities.Section) in various places, but no success. Can anyone help??
Your query is returning an IQueryable, which could have several items. For example, think of the difference between an Array or List of objects and a single object. It doesn't know how to convert the List to a single object, which one should it take? The first? The last?
You need to tell it specifically to only take one item.
e.g.
public PAWeb.Domain.Entities.Section GetSection(int SectionId)
{
var _section = from s in DataContext.Sections where s.SectionId == SectionId select s;
return _section.Select(x => new PAWeb.Domain.Entities.Section()
{
SectionId = x.SectionId,
Title = x.Title,
UrlTitle = x.UrlTitle,
NavTitle = x.NavTitle,
AreaId = x.AreaId,
Ordinal = x.Ordinal
}
).FirstOrDefault();
}
This will either return the first item, or null if there are no items that match your query. In your case that won't happen unless the table is empty since you don't have a where clause.
