I have been adding validation to a RadGrid, whenever i try to add any Validation groups it causes the RequiredFieldValidator to not work at all

Is there any work around for this? I would like to have a summary of errors listed

Hello,

Please also set for validationGroup for Insert/Update Button.

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)

{

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

{

if (e.Item is GridDataInsertItem)

{

GridEditableItem editItem = (GridEditableItem)e.Item;

LinkButton InsertButton = (LinkButton)editItem.FindControl("PerformInsertButton");

InsertButton.ValidationGroup = "YourValidationGroup";

}

else

{

GridEditableItem editItem = (GridEditableItem)e.Item;

LinkButton updateButton = (LinkButton)editItem.FindControl("UpdateButton");

updateButton.ValidationGroup = "YourValidationGroup";

}

Thanks,
