i'm trying to figure out why my kendo react dropdownlist doesn't show any data
To be precise NO DATA FOUND.
Below there is the snippet of code with the configuration of the dropdownlist
<DropDownList
data={countryList}
defaultValue={"Please select country"}
onChange={handleCountryChange}
/>
And there is the content oh countryList when i do a console.log(countryList)
0: "Afghanistan"
1: "Albania"
2: "Algeria"
3: "Andorra"
4: "Angola"
5: "Argentina"
6: "Armenia"
7: "Australia"
and so on for all the countries
Any help would be appreciated!
Ok, I've found the solution:
In DropDownList you have to include also:
- textFieled={"name"}
- value={"admincode"}
So I can resume that textField is the data that you want to display in the DropDown and value is the value of the corresponding textField element

the normal way in kendo ui grid update data is add a edit popup.
What I want is, Think I change a value in text field.In update I added switch case and change the submit value. Then It will add that value and return that values to the grid. But I want to do is when get the return value and change it and show a different value in the grid.
Here is a example.....
In edit popup it has a input text field. I submit a value as "A". In the update I add a switch tells that If the value is "A" change the submit value to 1(number one).
Then it submit the value and show the value in grid as "1" not as the "A".
How I do this ???
I think you want a custom handler. In the grid you toss in this:
edit: function(e) {onEdit(e)},
and then on top of the page you do whatever logic you want to do
function onEdit(e) {
if (true) {
$("#Whatever").text('Hello') //Whatever in this case is a field in grid
I'm working on mvc$ webgrid viewer, my grid viewer lists all columns exactlly as I want but there is one problem when I sort grid content by clicking on the hyperlink of the column names it sorts for all the columns except the drop down menu or DropDownList in mvc viwer.
[![mvc4 webgrid view screenshoot][1]][1]
DropDownList is not sorted as the other column values.
call a function that have the set of selectlist items. for example, in my case it works when I make the webgrid as follows:
grid.Column(columnName: "ContractFileNamesList", header: "ContractFileNamesList", format: #item => Html.DropDownList("filename",
, "-- Select One --"))
especially,
(IEnumerable)Model.ContractBOModel[rowVal -
1].FileNameListsFunction(fileNameStr);
I have a telerik:RadGrid that contains Bound Data,
I am calling Popup Edit Control Of RadGrid, I am getting all the fields and edit works fine.
What I want to do is from the Edit Popup, Edit one of the fields (Which is a RadTextBox) by clicking a button to open a RadWindow, this Window Contains another RadGrid with user details and one of the column with a button that executes RadGrid_OnCommand event, I am passing one of the values of the Grid by:
CommandArguments='<%# Eval("UserName")%>'
How can I place this value to the RadTextBox.Text in the Edit PopUp, So that I can update the grid with the selected value?
I would really appreciate any help. Thank you in Advance
I solved the issue by geting the grid row, which is in edit mode so I got the value of which row I need to change and updated its Editible item by ID using this code:
var rowid = RadGrid1.EditIndexes[RadGrid1.EditIndexes.Count-1];
GridEditFormItem rowEditControls;
foreach (GridDataItem row in RadGrid1.Items)
{
if (row.ItemIndex == int.Parse(rowid))
{
rowEditControls = row.EditFormItem;
((rowEditControls as GridEditableItem).FindControl("ID") as RadTextBox).Text = e.CommandArgument.ToString();
}
}
I Hope this will be helpfull for someone, I find it valuable for customising your edit forms.
I am facing problem in Jqgrid. I have a column with hyperlink and on the click of that hyperlink I want row data. Is this possible using Jqgrid. when I am using "getGridParam" I am getting row id as null.
There are two possibilities you can try here:
1) You can use a custom formatter to create the hyperlink, and have a custom attribute on the link where you put in the rowid (prefix the custom attribute name with 'data-' to keep it html5 compatible). Alternatively you could call a javascript function explicitly passing the row id.
2) Instead of the hyperlink's event itself, try using the onCellSelect event of jqGrid where you get the row and column id of the clicked cell, even if its a hyperlink. But this would trigger the event even if the user clicks anywhere inside the cell, not just on the link!.
I'm sure you found the answer to this by now but for some of you using ASP.NET WebForm here is what I used.
Create the Custom Formatter and add it to the column where you want the link to appear:
My columns are from a database I use a Select statement as so:
switch (jqGrdCol.DataField)
{
case "xxx":
CustomFormatter hypLinkxxx = new CustomFormatter();
hypLinkxxx.FormatFunction = "xxxformatOperations"; --> **JavaScript Function**
jqGrdCol.Formatter.Add(hypLinkxxx);
break;
}
Then in the Javascript function:
function xxxformatOperations(cellvalue, options, rowObject) {
return "<a href=somefile.aspx?xxx=" + rowObject[0] >" + cellvalue + "</font></a>"
}
I get the value of the column as a hyperlink.
I had a similar issue and was did look into your question to figure out a solution and I have found out a solution to this.
The solution is by using onCellSelect: function(rowid, index, contents, event)
this gives the rowid and contents ie the content of the cell you have clicked or selected
therfore you can get the entire row of contents which includes your hyperlink as well
I'm using jqGrid's filterToolbar method to let users quick search/filter the grid data. I'm using loadonce: true and datatype: local as my grid configs. I have a drop-down (select) filter type for one of my columns, which works fine.
Problem is when i try to update a row (using setRowData) that is not visible (because the filter/search result is hiding them), the row doesn't get updated when I reshow them by clearing the filter.
Any suggestions? I've tried triggering the reloadGrid event too, no luck.
Cheers
Update 1 - Reproducing the problem:
Here's how to reproduce the problem, using jqGrid's official demos:
Step 1
Browse to the jqGrid's demo page, and open the demo named 'Toolbar search' under 'New in version 3.7'
Step 2
In the demo grid, filter by the code column with the value 575878 so that only the first row is shown on the grid.
Step 3
Bring up the javascript console and update a row that's not currently visible, in this example update row 2:
jQuery("#toolbar").jqGrid('setRowData',2,{item_id:2,item:'blargh',item_cd:12345678});
Step 4
Unhide all the rows by clearing the filter value, and see that row 2 has not been updated!
Anything I'm doing wrong here? Possible workarounds?
You misunderstand how the grid are build. Grid can contain hidden columns, but no hidden rows. If one filter grid the full grid body will be removed and only the filtered rows will be inserted.
The method setRowData can be used to modify any row of the grid, but you can't modify something which is not present in the grid.
If you use local grid (datatype: 'local') then the data which you save in the grid will be saved in two internal jqGrid parameters data and _index. So you should modify the data object. To fill grid with modified data you need call .trigger("reloadGrid").
So if you want modify columns item_id, item and item_cd of the grid's data for the rowid=2 you can do the following steps.
1) Get references to the internal jqGrid parameters data and _index:
var $myGrid = jQuery("#toolbar"),
data = $myGrid.jqGrid('getGridParam', 'data'),
index = $myGrid.jqGrid('getGridParam', '_index');
2) Get reference to the object which represent the rowid which you need:
var rowId = '2',
itemIndex = index[rowId],
rowItem = data[itemIndex];
3) Modify the data item like you as need:
rowItem.item_id = 2;
rowItem.item = 'blargh';
rowItem.item_cd = 12345678;
4) Refresh grid contain (if needed) by reloading the grid
$myGrid.trigger('reloadGrid');
