Re: Error Use of unassigned local variable 'ClientScript'

Thanks for your help... but when i try as you suggest i get another error..

Error 1 ' does not contain a definition for 'ClientScript' and no extension method 'ClientScript' accepting a first argument of type 'GUInterface.SqlManager' could be found (are you missing a using directive or an assembly reference?)

I dont know why....

Small change in your code:

string strScript = null;
ClientScriptManager ClientScript = Page.ClientScript;
strScript = "window.open('popupContent.aspx','new_Win','height=650,width=250,resizable=0')";
ClientScript.RegisterClientScriptBlock(this.GetType(), "popup", strScript, true);

View line number 2.

Why to create a new object unnecesarily ?

Btw, I noticed your last name is Manas. Smile | :)

In Hindi, it means some one who is very close to heart. What does it mean in your language?

There's no object created there... just a reference to one which already exists on the Page class.

Hey manas, as everybody else suggested... Referring to a variable to the same object doesnt actually create a variable. Rather it just places the pointer to the same variable if the reference is derived from Object.

If its Value Types this would be different. Thus

ClientScriptManager ClientScript = Page.ClientScript
ClientScript.RegisterClientScriptBlock is same as
Page.ClientScript.RegisterScriptBlock

Rather than using RegisterClientScriptBlock, it is better to use RegisterStarupScript

use

if(!this.ClientScript.IsClientScriptBlockRegistered("myscript"))
this.ClientScript.RegisterStartupScript(this.GetType(), "myscript", strScript , true);

Hope this helps. Rose | [Rose]

Make sure one things : if you have AJAX Script Manager in your page, then you have to use ScriptManager rather than ClientScript. Smile | :)

Yes... RegisterStartupScript places the script after all the objects are rendered while RegisterClientScriptBlock places the JS at the beginning.

Thus say you are calling a javascript using RegisterClientScriptBlock which gets an element, you will find this null, as the script gets executed just before any html is rendered. In case of RegisterStartupScript the script is placed after the html is generated. So If you want to place a javascript call in your html, always use RegisterStartupScript.

Hope you got it. If not I can give you examples. Smile | :)

Can you atleast wrap the code. It is not readable.

Secondly, do you think anybody is gonna read all code of yours. Please narrow it down.
