RadGrid / GridTableView ItemCommand not firing

I have a RadGrid that contains a GridTableView in the DetailTables, as such:

<telerik:RadGrid ID="RelatedProductsGrid" runat="server" Width="95%" ShowStatusBar="true"

AutoGenerateColumns="False" PageSize="20" AllowSorting="False" AllowMultiRowSelection="False"

AllowPaging="True">

<pagerstyle mode="NextPrevAndNumeric"></pagerstyle>

<mastertableview width="100%" datakeynames="PartId" allowmulticolumnsorting="False">

<DetailTables>

<telerik:GridTableView DataKeyNames="PartId" Name="RelatedProducts" Width="100%">

<Columns>

...

<telerik:GridTemplateColumn HeaderStyle-HorizontalAlign="Right" ItemStyle-HorizontalAlign="Right">

<ItemTemplate>

<telerik:RadButton ID="RemoveRelatedProductButton" runat="server" CommandName="Delete">

</telerik:RadButton>

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</telerik:GridTableView>

</DetailTables>

So, the above button, "RemoveRelatedProductButton" shows up allright, but whenever I press it - nothing happens.

I have this in the code behind:

_relatedProductsGrid = FindControl("RelatedProductsGrid") as RadGrid;
_relatedProductsGrid.ItemCommand += RelatedProductsGrid_ItemCommand;

And finally:

protected void RelatedProductsGrid_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
{
if (e.CommandName == "Delete")

etc.

However, this method never fires. What do I need to do?

"Requested registry access is not allowed"?

When I upgrade an existing project to a newer version the Upgrade Wizard Log shows success but I get this error:

https://drive.google.com/open?id=1l1KqfmqRnsCgWJ5O5LeBDCH_fpjDoiRr

Also if I bring up the Launch Toolbox Configurator and then click "Finish" button, I get the same error.

I do NOT run VS 2015 "As Admin" for many reason I don't want to get into, so please don't suggest that ;)

Cheers, Rob.

which telerik control acts like an ASP.NET Datalist?

Hi All

I have an ASP.NET datalist which is displaying data in the form of a repeated list.

I have set the RepeatColumns to 6, so that I have the data displayed repeatedly in 6 columns.

Is there a telerik control that can do this, ie repeat the data in columns?

I tried using a RadGrid but cannot get the data to display in 6 columns.

Any help is very much appreciated.

Thanks

Johann

CommandItemSettings AddNewRecordButton and CSS

There are only two settings I can set from the aspx file for the AddNewRecord Button of a radgrid (when it's visible).

CommandItemSettings-AddNewRecordText
CommandItemSettings-AddNewRecordImageUrl

...but this is not enough.

Is there a way to control the appearance of the add button with css?

I can do this for the edit button (for example) of each row by:

Dim ImgBtn As ImageButton = DirectCast(e.Item.FindControl("EditCommandColumn"), ImageButton)
ImgBtn.CssClass = "editbutton"

...in the itemCreated event.

Thanks

TreeList delete confirmation

Hi,

I can successfully delete rows from my TreeList but I need to show the user a popup confirmation box first. I have searched extensively for a solution and cannot find anything.

My code for removing a row is listed below:

protected void OnSettingsTreeListDeleteCommand(object sender, TreeListCommandEventArgs e)

{

TreeListDataItem treeListDataItem = e.Item as TreeListDataItem;

TableRow tableRow = e.Item as TableRow;

if (treeListDataItem != null && tableRow != null)

{

string name = tableRow.Cells[3].Text;

string id = treeListDataItem.GetDataKeyValue("Id").ToString();

SettingsTreeListDataTable.Rows.RemoveAt(Convert.ToInt32(id));

PropertyType.GetPropertyType(typeof(Brand)).RemoveSetting(name);

}

I guess I need some kind of java script popup.

Thanks

SurfRat.

Breaking Change for RadTreeList in 2014.1.403.40?

I upgraded from 2013.3.1324.40 to 2014.1.403.40 and when I perform DataBind() on my RadTreeList it fails with:

An unhandled exception of type 'System.StackOverflowException' occurred in mscorlib.dll

I switch back to the old version and it works fine.

Was there a breaking change for 2014.1.403.40?

Thanks,

Dave
