[Solved] radgrid <telerik:GridButtonColumn

[Tony Abou-Akl]

Hi there
i have a radgrid with Gridbuttoncolumn, i would like to execute a javascript code to check if i can delete this record. Is there a way to call a javascrip funtion first then execute the Delete comand 
 

<

 

telerik:GridButtonColumn ConfirmText="Delete this?" ConfirmDialogType="Classic" ConfirmTitle="Delete" ButtonType="ImageButton"

 

 

CommandName="Delete" Text="Delete" UniqueName="DeleteColumn"

Thanks
Tony

Hi Tony,

I hope you need to execute a client side code before showing the confirm and then fire the server side DeleteCommand. If so here is a sample code which I tried on my end. You may alter the logic accordingly.

ASPX:

<telerik:GridButtonColumn  ButtonType="ImageButton" CommandName="Delete" Text="Delete" UniqueName="DeleteColumn" ImageUrl="~/Images/Delete.gif">
 </telerik:GridButtonColumn>

CS:

 protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridDataItem)
        {
            GridDataItem item = (GridDataItem)e.Item;
            ImageButton deleteBtn = (ImageButton)item["DeleteColumn"].Controls[0];
            deleteBtn.Attributes.Add("OnClick","return ConfirmDelete('"+ item.ItemIndex +"');");
        }
    }

JS:

<script type="text/javascript">

function ConfirmDelete(rowindex)
{
  if(rowindex==1)
   if(confirm("Delete this?"))
    return true;
    else
    return false;
}



</script>

Thanks

Hi, I have a similar question, but in my case I also have a DetailsTable in my RadGrid. Using the above example I receive an error on the following line when the ItemDataBound event is called for my Details table because I do not have a DeleteColumn in the Details table.

ImageButton deleteBtn = (ImageButton)item["DeleteColumn"].Controls[0];

My question is, how do I determine if the current table is the Details table so that I can skip calling the above line of code?

Thanks, -Scott

Hi Scott,

You can diferentiate between the detailtable and the mastertable using the Name properties of the ownertableviews as shown below:
aspx:

<telerik:RadGrid ID="RadGrid1" DataSourceID="SqlDataSource1" runat="server" OnItemDataBound="RadGrid1_ItemDataBound">
     <MasterTableView Name="Master" DataSourceID="SqlDataSource1">
           <DetailTables>
                 <telerik:GridTableView Name="Detail" DataSourceID="SqlDataSource1" runat="server">

c#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridDataItem && e.Item.OwnerTableView.Name=="Master")
        {
            GridDataItem item = (GridDataItem)e.Item;
            ImageButton deleteBtn = (ImageButton)item["DeleteColumn"].Controls[0];
            deleteBtn.Attributes.Add("OnClick","return ConfirmDelete('"+ item.ItemIndex +"');");
        }
    }

Thanks
