Radgrid and Toolbar Inheritance

[Karl]

 

Hi,

I’ve been working on a Custom Radgrid and Radtoolbar control which works very well.  At the moment the javascript used is still in the design view of the page and want to include this in my control dll. I’ve looked around the site and can’t find any examples of how to go about doing this.

 

How would I go about including the below in my code:

function RowClick(sender, eventArgs) {

            if (editedRow != null && hasChanges) {

                if (confirm("Update changes?")) {

                    hasChanges = false;

                    $find("<%=gvGrid.MasterTableView.ClientID %>").updateItem(editedRow);

                }

                else {

                    hasChanges = false;

                }

            }

        }

 

Also how would I change it so gvGrid is dynamic so I can have different names for my grids etc.

 

Any pointers in the right direction would be great.

 

Thanks

Hello Karl,

There are plenty of approaches for loading client scripts from your server control dynamically. The simplest is to hard-code the script appending the ClientID of the MasterTableView from inside the control:

private string rowClickScript = "function RowClick(sender, eventArgs) { if (editedRow != null && hasChanges) { if (confirm('Update changes?')) { hasChanges = false; $find('" + this.MasterTableView.ClientID + "').updateItem(editedRow); } else { hasChanges = false; } } }";

Then you can add this script to the page together with your server control:

protected override void Render(HtmlTextWriter writer)
{
    // render your control
    writer.Write("<script>" + rowClickScript + "/<script>");
}

However, a more flexible and conforming approach would be to make add this script in to a .js file in your assembly and load it as a script resource. Here is more info on ASP.NET AJAX script control development:

MSDN: Adding client capabilities to a web server control

You do not necessarily need to implement a client-side component for your control, but you include its scripts in the way depicted in the article.
