Hi,

I have a RadGrid that binds using NeedDataSource. The NeedDataSource calls a tableadapter that uses a combobox SelectedValue as an input parameter. So the grid is populated based on the SelectedValue.

That works fine when the page first loads. Though I am having issues with when I change a combobox SelectedValue.

I believe it is a matter of the event ordering. As in the NeedDataSource kicks off BEFORE the SelectedIndexChanged is fired.

Below is my RadGrid:

<telerik:RadFilter ID="WorkOrderItemsRadFilter" runat="server" Skin="WebBlue" ShowApplyButton="true"

OnApplyExpressions="WorkOrderItemsRadFilter_Apply" ApplyButtonText="Filter Work Order Items"

OnPreRender="WorkOrderItemsRadFilter_PreRender" OnFieldEditorCreating="RadFilter_FieldEditorCreating" OnItemCommand="WorkOrderItemsRadFilter_ItemCommand">

<FieldEditors>

else if (myCmdArg == "MATERIALGRADEID")

{

e.Canceled = true;

RadFilterStartsWithFilterExpression item = new RadFilterStartsWithFilterExpression(e.CommandArgument.ToString());

//replace the current item with the new item that has the default filter set to StartsWith

int i = e.ExpressionItem.ItemIndex;

e.ExpressionItem.OwnerGroup.Expression.Expressions.RemoveAt(i);

e.ExpressionItem.OwnerGroup.Expression.Expressions.Insert(i, item);

item.Value = "0";//DEFAULT THIS TO ZERO

WorkOrderItemsRadFilter.RecreateControl();

In IE 10 with RTL, the control (textbox and the select button) disappears once it’s being clicked.

You can notice the problem in telerik’s demos:
