[Solved] CompareValidator stops validating in hierarchy grid

[psiegers45]

Hi, I'm having problems getting my CompareValidator working inside my grid.
 
My grid uses a simple two level hierarchy. First level is a datetime, second level is a detail table with zero, one or more items.

In the detailtable there is a TABLE with a couple of TDs. These TDs are programmatically set to visible or invisible. Each TD has some controls.

One TD has a textbox and an input field (set to invisible), and also a Repeater that contains zero, one or more CompareValidators. Each CompareValidator validates against the invisible input field (which contains a copy of the parental user textbox).

I inject each CompareValidator in the Repeater ItemDataBound event handler.

This validation works until the value to compare results to false, and after that changing the value to a correct one does not cause the error message to disappear. Consequently, the form does not submit and the values in the grid are not updated nor validated.

I read that I should be using RadGrid's ItemCreated event handler to add CompareValidators but I cannot do that since it depends on each item in detail table if it has or not some special value. Also, I should be able to validate against more than one rule (indicated by the repeater) so there's the use of the repeater.

See code below. If anyone can shed light on the issue please do so!

        protected void repeaterPoliticas_ItemDataBound(object sender, System.Web.UI.WebControls.RepeaterItemEventArgs e)
        {
            RepeaterItem i = e.Item;

            if (i.ItemType == ListItemType.Item ||
                i.ItemType == ListItemType.AlternatingItem)
            {
                CompareValidator cv = (CompareValidator)i.FindControl("cvMontoPolitica");

                if (cv != null)
                {
                    DataRow data = (DataRow)i.DataItem;
                    HtmlInputText hdnAux = (HtmlInputText)i.FindControl("hdnAux");
                    hdnAux.Value = ((TextBox)hdnAux.Parent.Parent.Parent.FindControl("txtMonto")).Text;
                    cv.ControlToValidate = hdnAux.ID;
                    cv.ValueToCompare = Convert.ToString(data["monto"]);
                    cv.Operator = (ValidationCompareOperator)Convert.ToInt32(data["operador"]);

                    TextBox txtMonto = ((TextBox)hdnAux.Parent.Parent.Parent.FindControl("txtMonto"));
                    txtMonto.ToolTip = Convert.ToString(data["descripcion"]);
                }
            }
        }

OK, let me put the Q in a very short way then... what is the recommended approach using a radgrid in hierarchy mode with zero, one or more comparevalidators against a value in a control that has to be validated on the client when visible?
Hope this gets more response...!

[Iana Tsolova]

Hi psiegers45,

Could you please confirm that the scenario implemention would work as desired if the validators, the validated controls and the repeater are outside the grid?
Also does it makes any difference if you disable ajax on the page?

All the best,

Hi thanks for your reply Lana.

I have made it work by eliminating the repeater altogether and adding the CompareValidators during runtime. Also, I have made sure no other Ajax library was used on this page, but as this is a port from a web application that was designed with VS.NET 2K3 and MagicAjax (mostly using control injection in placeholders to mimic masterpage) other controls on the same page (but in other tabs) still use this MagicAjax library.

Now I am still facing some javascript issues but these and the remaining issues are minor so the port to Radgrid has been a successful one.

Regards and thanks,
Pieter
