Hi Carlos,

I guess you want to show the confirmation box on the click of Delete button.Please try the following code snippet.

ASPX:

<telerik:GridButtonColumn ConfirmText="Delete this product?" ConfirmDialogType="RadWindow" ConfirmTitle="Delete" ButtonType="ImageButton" CommandName="Delete" Text="Delete"  UniqueName="DeleteColumn">
    <ItemStyle HorizontalAlign="Center" CssClass="MyImageButton"></ItemStyle>
</telerik:GridButtonColumn>

Thanks,
Princy

Hi Carlos,

Please add the code inside the Columns of the MasterTableView as shown below.

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="true" >
    <MasterTableView >
        <Columns>
            <telerik:GridButtonColumn ConfirmText="Delete this product?" ConfirmDialogType="RadWindow"
                ConfirmTitle="Delete" ButtonType="ImageButton" CommandName="Delete" Text="Delete"
                UniqueName="DeleteColumn">
                <ItemStyle HorizontalAlign="Center" CssClass="MyImageButton"></ItemStyle>
            </telerik:GridButtonColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

Thanks,

Hi Carlos,

I guess you are using AutoGenerateDeleteColumn="true" and to add confirmation to it,please try the following code snippet.

C#:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
   {
       if (e.Item is GridDataItem)
       {
           GridDataItem item = (GridDataItem)e.Item;
           LinkButton lnkBtnDelete = (LinkButton)item["AutoGeneratedDeleteColumn"].Controls[0];
           lnkBtnDelete.Attributes["onclick"] = "javascript:return confirm(\'Do you want to delete this item?\')";
       }
   }

Thanks,

Hi all,

So now i havea new problem, how do i acess the fields on the add record on a editform?? Remember i have autogenerated columns.

Best Regards

Hi Carlos,

I'm not clear about your requirement,If you want to access the Grid in Insert Mode please try the following code snippet.

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
  {
      if (e.Item is GridEditFormInsertItem || e.Item is GridDataInsertItem) //Check if in InsertMode
      {
         //Your Code
      }
  }

OR if you want to access the form in Insert Mode in InsertCommand,Please try the following.

When you set the AutoGenerateColumns property of RadGrid to true, the RadGrid control generates a separate column for each data field in the control's assigned datasource. Based on the datatype of the field, the control will generate:

• GridBoundColumn for string fields

• GridCheckBoxColumn for boolean fields

• GridDateTimeColumn for datetime fields

• GridNumericColumn for numeric fields

C#:

protected void RadGrid1_InsertCommand(object sender, GridCommandEventArgs e)

    {

        if (e.Item is GridEditableItem)

        {

            GridEditableItem insertitem = e.Item as GridEditableItem;

            foreach (GridColumn col in RadGrid1.MasterTableView.AutoGeneratedColumns)

            {

                if (col.DataType == typeof(int))

                {

                    RadNumericTextBox numtxt = (RadNumericTextBox)insertitem[col.UniqueName].Controls[0]; //Accessing the textbox in insertmode

                    string id = numtxt.Text; // Get the values of the Numeric column                  

                }

                //Similarly check for other Data Types


            }

        }

    }

Thanks,

Hello Carlos,

You can refer to the following article for accessing the generated controls in edit mode:
( Section Accessing controls in edit/insert mode )
http://www.telerik.com/help/aspnet-ajax/grid-accessing-cells-and-rows.html

Hope this helps.
