Hi,

Im using a RadGrid for editing participants in an event.

I Would like to validate the email adress before comitting the data.

The problem is now that if i have more than one row in EditState and trys to commit one of the rows is validates all rows in editState?

Why is that? and how to avoid it?

Here is the code to my grid:

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<script type="text/javascript">

function RowDblClick(sender, eventArgs) {

sender.get_masterTableView().editItem(eventArgs.get_itemIndexHierarchical());

}

</script>

Hi Jacob,

You will need to use ValidationGroups:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)

{

if (e.Item is GridEditableItem && e.Item.IsInEditMode)

{

GridEditableItem editableItem = e.Item as GridEditableItem;

RequiredFieldValidator validator = editableItem["TemplateColumnName"].FindControl("RequiredFieldValidator1") as RequiredFieldValidator;

LinkButton updateButton = editableItem.FindControl("AutoGeneratedUpdateButton") as LinkButton;

validator.ValidationGroup = e.Item.ClientID;

updateButton.ValidationGroup = e.Item.ClientID;

}

Hope this helps. Please give it a try and let me know if it works for you.

All the best,
