[Solved] delete link on radgrid performs delete function on edit mode

[Pinkey]

Hi,
I have a RadGrid with delete and edit link as one of its columns. If i edit  a record, it opens in Editform on grid.
When working on edit form of rad grid if I click on Delete link on radgrid at the back of editform, it still performs the delete operation
even though one record is in edit mode.
following is the way by which I am declaring the Delete link.

 

<telerik:GridTemplateColumn UniqueName="DeleteColumn" ItemStyle-VerticalAlign="Middle" ItemStyle-HorizontalAlign="Center">

 

<ItemTemplate>

 

 

 

          <asp:LinkButton runat="server" CausesValidation="false" OnClientClick ="if (confirm('Are You Sure You Wish To Delete This Item?'))return true; else return false;"  CommandName="Delete" Text="Delete" ID="btnDelete" ForeColor="Blue"></asp:LinkButton> </ItemTemplate>

 

 

 

</telerik:GridTemplateColumn>

 

 

 

 

Please guide me how i can avoid this?

Thanks
Pinkey

Hello Pinkey,

You can disable the Delete buttons when RadGrid is in Edit mode.

<telerik:GridTemplateColumn HeaderText="Delete">
    <ItemTemplate>
        <asp:LinkButton runat="server" Enabled='<%# RadGrid1.EditIndexes.Count == 0 %>' Text="Delete"
            CommandName="Delete" />
    </ItemTemplate>

Hello,

I am sure that the above code will work fine. But when I tried on my end, the confirmation is shown evenif the LinkButton is disabled. So I tried following code to avoid confirmation window when the row is in Editmode.

ASPX:

<telerik:GridTemplateColumn UniqueName="DeleteColumn" ItemStyle-VerticalAlign="Middle" ItemStyle-HorizontalAlign="Center">
    <ItemTemplate>
        <asp:LinkButton runat="server" CausesValidation="false" OnClientClick="if (confirm('Are You Sure You Wish To Delete This Item?'))return true; else return false;"
            CommandName="Delete" Text="Delete" ID="btnDelete" ForeColor="Blue"></asp:LinkButton>
    </ItemTemplate>
</telerik:GridTemplateColumn>

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridEditableItem && e.Item.IsInEditMode && !e.Item.OwnerTableView.IsItemInserted)
    {
        GridEditableItem editItem = e.Item as GridEditableItem;
        GridDataItem item = (GridDataItem)((Telerik.Web.UI.GridEditFormItem)(editItem)).ParentItem;
        LinkButton btnDelete = (LinkButton)item.FindControl("btnDelete");
        btnDelete.Enabled = false;
        btnDelete.OnClientClick = null;
    }
}

Thanks,
Princy.

Princy, thank you the comment.

This "limitation" could be easily avoided with a simple check:

Example:

... OnClientClick="if (this.disabled) return false; if (confirm('Are You Sure You Wish To Delete This Item?'))return true; else return false;" />

Keep up the good work.
