[Solved] How to "find" a radtoolbar in a radgrid

[Stacy]

I have this layout:

<RadGrid>
   <MasterTableView>
      <CommandItemTemplate>
         <RadToolBar>

How can I "find" the radtoolbar to disable buttons?  I can do a "myControl.FindControl("myGrid")... but i cannot find the toolbar do enable/disable it.  I can also do a grid.MasterTableView.GetColumn("myButton").Visible = false but again, can't seem to "find" the toolbar or it's buttons.

Hello,

<CommandItemTemplate>
                   <telerik:RadToolBar ID="RadToolBar1" runat="server">
                       <Items>
                           <telerik:RadToolBarButton id="RadToolBarButton1" runat="server" Text="RadToolBarButton1"
                               Value="RadToolBarButton1">
                           </telerik:RadToolBarButton>
                       </Items>
                   </telerik:RadToolBar>
               </CommandItemTemplate>

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
        {
            if (e.Item is GridCommandItem)
            {
                GridCommandItem item = (GridCommandItem)e.Item;
                RadToolBar RadToolBar1 = item.FindControl("RadToolBar1") as RadToolBar;
                RadToolBarButton RadToolBarButton1 = RadToolBar1.FindItemByValue("RadToolBarButton1") as RadToolBarButton;

                // you can do your logic here
            }
        }

let me know if any concern.

Thanks,

Can this be used outside of the " RadGrid1_ItemDataBound" method?  This is not where I want to perform any logic.

Hello Stacy,

Try the following code snippet in Button Click.
C#:

protected void Button1_Click(object sender, EventArgs e)
 {
    GridCommandItem cmdItem = (GridCommandItem)grid1.MasterTableView.GetItems(GridItemType.CommandItem)[0];
    RadToolBar RadToolBar1 = cmdItem.FindControl("RadToolBar1") as RadToolBar;
    RadToolBarButton RadToolBarButton1 = RadToolBar1.FindItemByValue("RadToolBarButton1") as RadToolBarButton;
 }

Thanks,
Princy.

If I use this code below...I get an index out of range exception because there are 0
items returned from the "GetItems" call...it does find the grid and mastertableview, but GetItems returns 0 items

protected void Page_Load(object sender, EventArgs e)

{

            Initialize();

}

 

 private void Initialize()

{

GridCommandItem cmdItem = (GridCommandItem)grid.MasterTableView.GetItems(GridItemType.CommandItem)[0];

}

Hello Stacy,

sorry but we are not able to get GridCommanditem in page load.
because after executing/completed the page_load event this GridCommandItem is created/generated so you have to do your functionality in Page_Prerender.

protected void Page_PreRender(object sender, EventArgs e)
    {
        GridCommandItem cmdItem = (GridCommandItem)RadGrid1.MasterTableView.GetItems(GridItemType.CommandItem)[0];
        RadToolBar RadToolBar1 = cmdItem.FindControl("RadToolBar1") as RadToolBar;
        RadToolBarButton RadToolBarButton1 = RadToolBar1.FindItemByValue("RadToolBarButton1") as RadToolBarButton;

    }

Let me know If any concern.

you can see ASP.NET Page Life Cycle Overview.
controls event fire after page_load.
so you can use above code any event but after the RadGrid_ItemCreated fired....like : button_click,page_prerender
