Hai,
     i am using radgridview. While editing the cell details i am using

radGridView_CellValidating

event.

In that,

 

void radGridView_CellValidating (object sender, Telerik.Windows.Controls.GridViewCellValidatingEventArgs e)

 

 

 

{
e.IsValid =

 

false;

 

e.ErrorMessage =

 

"Invalid Data(Some Message)";
}
It shows the error message when mouse over on the right top corner of tht red indication. But i need when focusing on that cell or immediate when error occurs(doesn't need tooltipservice). How can i do this?

Thanks in Advance.

Hi Nirmal,

Unfortunately with the current version of RadGridView control, this scenario is not supported. We plan to improve it and this will be the default behavior, but I cannot commit with any specific date or release when this feature will be ready. Meanwhile you can use data layer validation instead of UI validation in order to meet your goals. For more information you can take a look at this blog post.

I'm also facing the same problem. The link you provided is no longer working.
However error message is showing immediately when default validation is turned on but
if i give my own cell validations its not working.

Can please look into this issue again and let me know.

private void radLifeStyleDefault_CellValidating(object sender, GridViewCellValidatingEventArgs e)
        {
            if (e.Cell.Column.UniqueName == "ContactType")
            {
 
                if (e.NewValue.ToString() != "Call")
                {
                    e.IsValid = false;
                    e.ErrorMessage = "Enter Proper Call Attempt";
                }
                else
                {
                    e.IsValid = true;
                }
            }
        }
