Client Side Javascript can't reference WebGrid

Jim posted over 16 years ago

For some reason I can't set a reference to my web grid object. New to writing Client Side scripts so maybe i'm doing something wrong that's obvious to someone other than me. Any help would be greatly appreciated!

Is there a reason you aren't using the gridName input parameter?

I checked the value of that and got ctl00xContentPlaceHolder1xuwgChannels when I was expecting just the control name.

I was modeling my function off of an existing function in an infragistics sample:

    function SelectCurrent() {
        var grid = igtbl_getGridById("UltraWebGrid1");
        var row = igtbl_getActiveRow("UltraWebGrid1");
        if(row != null)
            igtbl_selectRow("UltraWebGrid1", row.Element.id, false, false);
        else {
            var cell = igtbl_getActiveCell("UltraWebGrid1");
            if(cell != null)
                igtbl_selectCell("UltraWebGrid1", cell.Element.id, false, false);
        }
        return 0;
    }

This sets the reference using only the controls name, I guess I'm confused on why that works but won't work for me if I pass only the control name. Using the gridName param does work for me though... in my frustrations i must have overlooked that do to the "ctl00xContentPlaceHolder1xuwgChannels " value it initially gave me.

The Grid in the sample is probably just a grid on the page, so it's only container is the page itself.

Container controls will append information upon the client id of control to ensure that each control on a page has an unique ID. Your WebGrid is inside a content pane

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">

<script type="text/javascript">
So the WebGrid's ID becomes : ContentPlaceHolder1xuwgChannels
And so on up the chain, as each parent gets involved, it appends more information.

If container controls didn't do this append, you could easily end up with multiple controls having the same ID on the client as all you would need are two ContentHolders who load up the same UserControl.
