RadGrid with Update Panel and Response.Write

[Deva Kumar]

Dear Experts,

I have a scenario with respect to usage of RadGrid with Update Panel and Response.Write. Could you please help on this?

I am getting - Sys.WebForms.PageRequestManagerParserErrorException.

I am placing the RadGrid within update panel to avoid the refresh problem.

I have a select button - GridButtonColumn on the rows - when I click on the select button - I invoke a response.write and I get the above error.

But I was able to avoid this error by calling the  asp:Postback trigger, but my very purpose of avoiding the screen refresh is gone.

Thanks in advance.

Thanks,
Deva

Hello Deva,

I recommend you put a regular literal control inside your UpdatePanel. This will work flawlessly with AJAX - instead of using Response.Write("something"), use Literal1.Text = "something".

Thanks Daniel.

But my problem is like -  I am creating a string on the select button event of the RadGrid

string sScript;
lblFieldValue = e.Item.FindControl("uxLblSiteInfoAddress1") as Label;
sScript += "window.opener.document.getElementById('" + Request.QueryString["sadd1"].ToString() + "').value = '" + lblFieldValue.Text.ToString() + "';";

Similarly I will creating a very big string consisting of many values selected in the grid and finally call

sScript += "}window.opener.__doPostBack();window.close();</script>";

Response.Write(sScript);

The above script will set the values of the text box and other Hidden controls and RadDatePicker values on the invoked form.
I feel that I cannot avoid using Resposnse.Write.

Could you please give me some directions on this? Thank you - Deva
