Calling Clinet Function from Code Behind (Inside Ajax Update panel)

Hi,

Can anyone please provide information on how I can do this:

I have a GridView control inside an Ajax Update panel and have wired the Selected IndexChanged action to call a Client side Javascript function (ViewReceipt()). Unfortunately it doesn't seem to work except if I take the control outside the update panel.

Have posted my code below..

protected void rgvInv_SelectedIndexChanged(object sender, EventArgs e)
{
// Now execute the client-side stuff...
StringBuilder sbScript = new StringBuilder();
sbScript.Append("\n<script language=\"JavaScript\" type=\"text/javascript\">\n");
sbScript.Append("<!--\n");
sbScript.Append("ViewReceipt();\n");
sbScript.Append("// -->\n");
sbScript.Append("</script>\n");
this.RegisterStartupScript("ClientSideCall", sbScript.ToString());
}

Regards..

Peter.

Hi,

Found some posts on this and tried to add the recommended code but still getting a syntax error, hope someone can help out..

code behind:

protected void rgvInv_SelectedIndexChanged(object sender, EventArgs e)
{
// Now execute the client-side stuff...
StringBuilder sbScript = new StringBuilder();
sbScript.Append("\n<script language=\"JavaScript\" type=\"text/javascript\">\n");
sbScript.Append("<!--\n");
sbScript.Append("EditReceipt();\n");
sbScript.Append("// -->\n");
sbScript.Append("</script>\n");
//this.RegisterStartupScript("ClientSideCall", sbScript.ToString());
//ScriptManager.RegisterStartupScript(this.UpdatePanel1, this.GetType(), "ClientSideCall", sbScript.ToString(), true);
ScriptManager.RegisterStartupScript(this, this.GetType(), "ClientSideCall", sbScript.ToString(), true);

}

Javascript Function:

function EditReceipt()
{
var manager = GetRadWindowManager();
var rwEntry = manager.GetWindowByName("rwReceipt");
}

Hi Peter,

The problem with your code is that you should specify the last parameter to false in RegisterStartupScript method.

This parameter indicates that <script> tag will be added automatically to wrap the sbScript. Since you've done that manually, so false should be used.

Like this:

ScriptManager.RegisterStartupScript(this, this.GetType(), "ClientSideCall", sbScript.ToString(), false);

Hope this helps.

Hi Peter,

Give full definition of EditScript() function then only I can help to you.

Raymond,

Thanks for the information, I have already implemented a work around by moving the grid outside of the update panel. I'm using a telerik grid which has inbuilt AJAX and there are some clientside events which can be hooked into that has given me the functionality I require, anyway thanks for the information I can use it else where later.

Regards..

Peter
