if you mean the grid view control then use the smart tag to edit columns and select the column u wanna edit go to the read only property and change it to true.
I donno if this helps.

hi folks.
When a asynchronous postback (ASP.NET AJAX) times out then the ClientScriptManager shows a dialog with the error message: Sys.WebForms.PageRequestManagerTimeoutException: The server request timed out.
Does anyone know how this text can be localized?
Note that this is not the same as when a asynchronous postback throws an exception. That can be handled with the ScriptManager_AsyncPostBackError event and a custom error message can be sent to the client.
happy programming

You're in the wrong place. We help people here. You seem to want somewhere where people will write apps for you. Expect to have to pay money if you want people to do that.

Source code for instant messaging using ajax with c# application.
You probably misinterpreted the message, it looks more like he/she is offering the source code to everybody.

I need to know how to run a .exe file on the client side.
i.e.: I need to open winword.exe or excel or acrobat.

This is a tetchy issue...
for security reasons you can not launch an EXE from ASP .net on the client side (... any hacker could just launch evil exe's).
But... if you can:
- If you want to just pregenarate an Office doc, you can send it as an stream to the client setting the content file to Excel or Word, it will open the excel file on the client side, maybe embedded on the nagivator.
- If you want to open an empty excel file you could send that as an stream (An empty excel file), following the same approach as the previous bullet.
- If you need to be able to execute the exe and you are on an intranet, on possiblity could be to have an ActiveX control that is installed on the client machine, BUT That's quite risky, I won't do that (security hole).

Yes, that will work, as would putting it in a hidden field that is a server control. What does your code look like ?

This is the function in javascript
function display()<br />
{<br />
var localpath1 = document.getElementById('lblerr');<br />
lblerr.innerText = localpath;<br />
}
it is diplaying the value on label. lblerr is the id of label. am calling this function on pageload
but when i try to get the value using lblerr.text, it is showing null.
y is it so?
how to get value on the label
|
|
|
|

i think this value that you are initialzing in javascript won't persist.
Do one thing Add hidden variable runat server and assign value to that hidden varaible and use that hidden varaible at server side like this
var label1=document.getElementById('hidden');<br />
<br />
label1.value="Sandeep";<br />
and at the server side just get the value from it
hidden.Value that will return you string
Thanks and Regards

It means that you are using the object whose instance is not creaetd yet
It will also give the line number. check the line number

on line number i have writen
string val=txtHidden.Value.ToString();
eat is wrong in this?
while debuging it is showing the value of txthiden as
txtHidden: <undefined value>: System.Web.UI.HtmlControls.HtmlInputHidden
am using .net 2003
|
|
|
|
|
OK don't add ToString();
just add
string val=txtHidden.Value;
And be sure that txtHidden is decalared in your application such as
System.Web.UI.HtmlControls.HtmlInputHidden txtHidden;
Thanks and Regards

Check the id of the hidden control in aspx page and aspx.cs both should be identical.
Could you post your whole page ?
Thanks and Regards
