I upgraded a .NET web application from .NET framework 2.0 to .NET framework 4.5. The Telerik controls were also upgraded, from Q3 2010 to Q3 2015. Due to the upgrade, the web application is experiencing some odd behavior which did not exist in the previous version. Mainly, the ItemCommand is not being raised at all on one of the grids. I have searched extensively and tried multiple solutions to no avail. I have included the relevant sections of code below. The source code is quite large and complex, so I won't be including all parts.

The command that should be firing, will result in filters being displayed. The radgrid contains a radtoolbar which contains a radtollbarbutton, when the button is clicked, I am expecting the item command event to be raised and the filter dialog to be displayed.

Hello Cliff,

I have gone through the code snippets, but I could not find anything that could prevent the ItemCommand from firing.

Here is a simple example that works correctly on my side:

<telerik:RadGrid ID="dgFolders" runat="server" AutoGenerateColumns="true" OnNeedDataSource="RadGrid1_NeedDataSource" OnItemCommand="dgFolders_ItemCommand"

AllowSorting="True" AllowPaging="True" Height="100%" EnableLinqExpressions="False">

<ClientSettings AllowColumnsReorder="true" ColumnsReorderMethod="Reorder" ReorderColumnsOnClient="true" Resizing-AllowColumnResize="true" Resizing-EnableRealTimeResize="true">

<Selecting AllowRowSelect="True" />

<Scrolling AllowScroll="True" UseStaticHeaders="True" />

<Resizing ClipCellContentOnResize="False" AllowColumnResize="true" />

</ClientSettings>

<FilterMenu OnClientShown="MenuShowing" />

<GroupingSettings CaseSensitive="False" />

<SelectedItemStyle Wrap="False" />

<FilterItemStyle Wrap="False" />

<AlternatingItemStyle Wrap="False" />

<ItemStyle Wrap="False" />

<PagerStyle AlwaysVisible="True" PagerTextFormat="{4} Displaying page {0} of {1}, items {2} to {3} of {5}. "

Mode="NextPrevNumericAndAdvanced" />

<MasterTableView Width="1110px" CommandItemDisplay="Top">

<CommandItemTemplate>

<telerik:RadToolBar ID="RadToolBar1" runat="server" SkinID="TelerikRadToolBar">

<Items>

<telerik:RadToolBarButton PostBack="true" Text="Toggle Filters" CheckOnClick="true" CommandName="ToggleFilter" ImageUrl="~/App_Themes/Custom/Grid/Filter.gif">

</telerik:RadToolBarButton>

<telerik:RadToolBarButton Text="Advanced Filter" CommandName="OpenRadFilter" ImageUrl="~/App_Themes/Custom/Grid/Filter.gif">

</telerik:RadToolBarButton>

</Items>

</telerik:RadToolBar>

</CommandItemTemplate>

</MasterTableView>

</telerik:RadGrid>

And the code-behind:

protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)

{

DataTable table = new DataTable();

table.Columns.Add("ID", typeof(int));

table.Columns.Add("Column1", typeof(int));

table.Columns.Add("Column2", typeof(int));

table.Columns.Add("Column3", typeof(int));

for (int i = 0; i < 5; i++)

{

table.Rows.Add(i, 20, 10, 410);

}

(sender as RadGrid).DataSource = table;

}

protected void dgFolders_ItemCommand(object sender, GridCommandEventArgs e)

{

}

Please ensure that there are no JavaScript errors on your page.

Hello Konstantin,

I created a test project and added the code provided in your example above. The dgFolders_ItemCommand is not firing in that scenario either. I placed a break point in visual studio on the dgFolders_ItemCommand, the breakpoint is never reached when clicking the Toggle Filters button.

Additionally, in the snippets I provided above, I discovered if the two other grids on the default page are commented out, DocumentGridControl1 and AdvSearchGridControl, then FolderGridControl1 (dgFolders) will raise the ItemCommand event correctly. It is not clear to me why the declaration of two additional grids on the page, would interfere with the ItemCommand event being raised. Again, this worked properly prior to the upgrade from Q3 2010 to Q3 2015.
