Problem validating the reuired fileds in the Add mode.

[SivaPrasad Bevara]

Hi,

I am using Telerik controls for Silverlight 5.

I wanted to validate the gridview row(Which have required fields) in the add mode.
I am trying to handle this in the RowValidating event.

I am doing this as below ( I am using a DTO object for loading the gird).

1)  Added an dependency property(IsRequired = true/false)
2)  Checking that property in the rowvalidating event to know whether it is required filed or not
3)  If it is required then I am checking its values,
4)  If the value is null then I am adding that to the "GridViewCellValidationResult" and finally I am adding that to the e.ValidationResults as below.

GridViewCellValidationResult validationResult = new GridViewCellValidationResult();
validationResult.PropertyName = propertyname;
validationResult.ErrorMessage = "ERROR: Column " + propertyname +" cannot be blank.";
e.ValidationResults.Add(validationResult);

I am doing the above, by looping through the all the columns. So All the error messages are added to a single message box.

The problem with this is, the summarised error message is displayed only after clicking on the last errored cell. I mean the error message is not showing up on the other cells till we get  into the last errored cell (which is added to the validationresult last).

I wanted to show the summarised message once the user get in to any cell whcih has the error or on mosue hover of the errored row.
Also I wanted to remove the errors from the message box one by one as the user fixes it.
Also I wanted to remove the error background automatically once all the errors fixed.

Please help.
