Prompt to save change in edit mode

[Tim]

I have a RadGrid that uses Inline edit mode.  My grid only supports editing one row at a time and all works fine so long as the user clickes the update button after editing the row to commit the changes to the database.

If the users has row 1 in edit mode and does not click update, but selects a different row to place into edit mode, I would like to pop up a message box asking the user if they want to save their changes before moving to edit the new row.

How can I accomplish this?  When a new row is placed into edit mode the previous row does not get a cancel event for me to trap.

Hello Tim,

This is one possible approach:

protected void RadGrid1_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
{
    if (e.CommandName == RadGrid.CancelCommandName && e.Item.IsInEditMode)
        Session["editMode"] = null;
    if (e.CommandName == RadGrid.UpdateCommandName) Session["editmode"] = null;
    if (e.CommandName == RadGrid.EditCommandName)        {
        if (Session["editMode"] != null)
            e.Canceled = true;
        else
            Session["editMode"] = "edit";
    }
}

Hi Tim,

You can also have a look at the following demo which sets the Grid in edit mode on double clicking a row and displays  a user-friendly confirm dialog to prompt whether the operation should be propagated or not.
Edit on double-click

Thanks

I know this post is very outdated, but I have one question : How can I achieve the same result (Prompt the user to choose if save or not to save) in client-side ?

Let me explain :
The user choose to insert a new row (in editform), then I have to validate a value.
If this value is <= X, then I have to prompt, otherwise it should insert the element without prompt the user.
I guess I have to do this client side, but I cannot find where to catch the 'onclick' event for the Insert button.

Thanks

Hello,

You can attach the onClick event to the insert button in the ItemCreated like below.

C#:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
  {
      if (e.Item is GridEditFormInsertItem && e.Item.OwnerTableView.IsItemInserted)
      {
          GridEditFormInsertItem insertItem = (GridEditFormInsertItem)e.Item;
          LinkButton insert = (LinkButton)insertItem.FindControl("PerformInsertButton");//accessing the insert button
          insert.Attributes.Add("onclick", "insert();");
      }
  }

javascript:

<script type="text/javascript">
    function insert()
    {
     //your code here
    }
</script>

Thanks,
Shinu.

thank you very much, that's a smart way to attach a client function indeed :-)
I'll try ASAP and let you know. Your help is appreciated

Thanx,
