Hi everybody,

Question 1: How do you set the values from server-side to a client-side
control or how do you execute a javascript function without a button click
event?
Question 2: How do you get response from a Confirm() popup window to
uncheck all server-side checkboxes placed in a panle of a web user control?

I am using ASP.Net 2.0, Thanks. Need info...

What ever asp.net control post back to your server even handler add
the following code

this.Page.RegisterStartupScript("StartupScript","< script>YourJavascriptFunctionName()</script>");



when page post back this method will be called on page load, if needed , you
can also pass value to your javascripr function from server side.

like below

this.Page.RegisterStartupScript("StartupScript","< script>YourJavascriptFunctionName('param1',
'param2')</script>");

Question 2: How do you get response from a Confirm() popup window to
uncheck all server-side checkboxes placed in a panle of a web user
control?
since you are return true or false in your confirmation , your delete button
event handler will be called back upon true,
there you can write your checkbox selection logic.

re: Javascript Server-side Action Questions..

Thanks Baski for replying...

I tried what you suggested in question 1, it's not working, what is wrong
with this?

Inside Parent user control:

RichTextEditor1.SetEditorContent(dr["Contents"].ToString());

Inside RichTextEditor user control class:

public void SetEditorContent(string contents)
{
this.EditorContent = contents;
//Page.ClientScript.RegisterClientScriptBlock(this.G etType(),
"RunFunction", "setTxt('" + contents + "')");
Page.RegisterStartupScript("StartupScript", "setTxt('" + contents +
"')");
}

The second question has been resolved in another post on this same forum.

re: Javascript Server-side Action Questions..

Baski,

I try to follow what you suggested as answer in question # 1, but it's
not working, Am I missing something or not doing it right?

Inside Parent User Control:

RichTextEditor1.SetEditorContent(dr["Contents"].ToString());

Inside RichTextEditor user control:

public void SetEditorContent(string contents)
{
this.EditorContent = contents;
//Page.ClientScript.RegisterClientScriptBlock(this.G etType(),

// "RunFunction", "setTxt('" + contents + "')");
Page.RegisterStartupScript("StartupScript", "setTxt('" + contents +
"')");
}

The second question has been answered in another post on this same forum.

re: Javascript Server-side Action Questions..

What error you got ? if you didn't get error , can you please uncheck
Disable Script Debugging (Ie and other) in IE's tools->iption->Advanced tab,
and rerun your application. It seems like you should get object not defined
error from javascript.

I tried what you suggested in question 1, it's not working, what is wrong
with this?

Inside Parent user control:

RichTextEditor1.SetEditorContent(dr["Contents"].ToString());

Inside RichTextEditor user control class:

public void SetEditorContent(string contents)
{
this.EditorContent = contents;
//Page.ClientScript.RegisterClientScriptBlock(this.G etType(),
"RunFunction", "setTxt('" + contents + "')");
Page.RegisterStartupScript("StartupScript", "setTxt('" + contents +

}

The second question has been resolved in another post on this same forum.

re: Javascript Server-side Action Questions..

I thought you might get java script error in pop up browser window. ON your
javasctip function try to add alert message as first line and make sure it
got executed. If it shows the alert message , set the break point in your
javascript function and debug.

Hi everybody,
>
Question 1: How do you set the values from server-side to a
client-side
control or how do you execute a javascript function without a button
click
event?
Question 2: How do you get response from a Confirm() popup window
to
uncheck all server-side checkboxes placed in a panle of a web user
control?

I am using ASP.Net 2.0, Thanks. Need info...
