Get radslider client grid.dataitem.findcontrol

[cbospikes]

Using  slider in a radgrid is perfect for a particular issue.  I have it all working except one thing.

I have placed a radslider in the header of my radgrid and am attempting to use it as a "select all" for the radsliders in the rows of the  associated column.  OnClientValueChange I am iterating thru the griddataitems and trying to use findcontrol to get a refrence to the slider and set the value.

I keep coming back with null.

Am I approaching this wrong or does this control not render in a fashion that allows me to do this?
Here is my javascript function:

function SelectDate(sender, eventArgs)
{

 var grid = $find("rgLoad").get_masterTableView();
 var griditems =grid.get_dataItems();
 
  for (var i=0; i<griditems.length; i++)        
        {    
         var slider = griditems[i].findControl("rslider");
         if(!slider==null)
            slider.set_value(sender.get_value());
        }


}

Let me know if I need to provide more info.

Hello cbospikes,
We are aware of this behavior and in case you wait for SP2 that we will release next week, griditems[i].findControl("rslider"); will return the RadSlider client object.

For the time being, I can offer you the following workaround:

<script type="text/javascript">
function SelectDate(sender, eventArgs)
{
    var grid = $find("rgLoad").get_masterTableView();
    var griditems =grid.get_dataItems();

    for (var i=0; i<griditems.length; i++)
    {
        var gridItemElement = griditems[i].get_element();
        var childElements = gridItemElement.getElementsByTagName("DIV");
        for(var j=0, length=childElements.length; j<length; j++)
        {
            var childElement = childElements[j];
            var childElementID = childElement.id;
            if(Sys.UI.DomElement.containsCssClass(childElement, 'radslider') && childElementID && childElementID.endsWith('rslider'))
            {
                var slider = $find(childElementID);
                if(slider)
                {
                    slider.set_value(50);
                }
            }
        }
    }
}
</script>

Hello,

Could you help me to find control in insert row (insertmode) ?

Thk you

Hello Bertrand,

If you would like to get reference to the control in the insert item on the server, you can do that inside the ItemCreated or ItemDataBound handlers of the grid as explained here:

http://www.telerik.com/help/aspnet-ajax/grddistinguisheditinsertmodeonitemcreateditemdatabound.html

In case you would like to obtain reference to it on the client, consider the approach presented in the code library thread linked below:
