RegisterClientScriptBlock problem

[Guest]

I have used RegisterClientScriptBlock in my ASP.NET page. it works well. Here I have problem. When Postback occurs, I dont want the script to be emitted. But It emits the Script even if I dont call the RegisterClientScriptBlock

How to prevent this?

 

[Hermit Dave]

if(!Page.IsPostback)
{
string strClientScriptIdent = "xyz";
if(!Page.IsClientScriptBlockRegistered(strClientScriptIdent)
{
string strClientScript = "blah blah blah";
Page.RegisterClientScriptBlock(strClientScriptIdent,
strClientScript);
}
}

Thanks for you reply. But my problem is little different
Let me explain the scenario to you
when I click on the button "A", I want the focus to be set to "TEXT1". So I call RegisterClientScriptBlock method to set the focus using javascript". it works fine
When I click on Button "B" in the same page I dont want to do anything regarding focus, so I didnt call RegisterClientScriptBlock methed this time
But still the Page persists the javascript which was previously emitted and set the focus to "TEXT1" which I dont want
How to remove the script which was emitted at the first tim

Thanks.

you dont need to mess about with the registerclient script.
instead of OnClick="javascriptfunction();"
use object.attibutes.add("onClick", "javascriptfunction();");
that way you only add the attributes for objects you want to have client
events.

Since I have to use this in lot of places (not only in button clicks) I have come up with the generic function like the one in below which emits javascript

public void SetFocusControl(string ControlName

string script = "<script language=\"javascript\"> var control = document.getElementById(\""
ControlName + "\");" + " if( control != null ){control.focus(); if(control.type == 'text') control.select();}" +
"</script>"
Page.RegisterStartupScript("Focus", script)


So whenever I want to set the focus to particular control I would call this fuction with that control name
when I dont want I dont call this, still the Page emits the javascript which was emitted at the last time
So I want to remove that script. is there any way to remove the registered script using the key or in some other way

Thanks

nope. i dont think there's a method to remove the registered script.
as a work around you could overwrite it to a emtpy javascript function or
something like that... or try just over writing it with ""
not sure whether it will work but its worth a try.

You must be calling this even when you think you're not. The script
blocks are maintained in an instance member of the Page class, so when a
new Page instance is created (which happens with each HTTP request) it
starts with an empty script block collection.

Set a breakpoint on the method, and you'll find the culprit.
