[Solved] RAD Grid client-side properties

[Viswanathan]

Hi,

I'm in the process of upgrading RAD Controls Q3 2007 version to Q2 2009 version. While accessing get_masterTableView().rows property, I am getting the following error here:

Microsoft JScript runtime error: 'get_masterTableView().rows.length' is null or not an object

Here is my code block: (in which some properties might refer to older version of the telerik control)

function fnColumnHeaderChecked(sender, eventArgs)
{
// Select or deselect all the rows of the grid.
for(var nCount = 0; nCount < $find('<%=rgMemberResult.ClientID %>').get_masterTableView().Rows.length; nCount++)
{
if( columnChecked == true )
{
if(!$find('<%=rgMemberResult.ClientID %>').get_masterTableView().rows[nCount].Selected)
{
// Select the row.
$find('<%=rgMemberResult.ClientID %>').get_masterTableView().selectRow(radGrid.get_masterTableView().Rows[nCount].Control, false);
}
}
else
{
// Deselect the row.
$find('<%=rgMemberResult.ClientID %>').get_masterTableView().SelectRow(radGrid.get_masterTableView().Rows[nCount].Control);
}
}
}

Please help me out to resolve my issue.

Thanks

Hi Viswanathan,

Try the following client side code for RadControls version Q2 2009.

JavaScript:

<script type="text/javascript">
function fnColumnHeaderChecked(sender, args)
{
    var columnChecked = false; // get the value whether checked or not
    var grid = $find('<%=RadGrid1.ClientID %>');
    for(var nCount = 0; nCount < grid.get_masterTableView().get_dataItems().length; nCount++)
    {
        if( columnChecked == true )
        {
            if(!grid.get_masterTableView().get_dataItems()[nCount].get_selected())
            {
                // Select the row.
                grid.get_masterTableView().get_dataItems()[nCount].set_selected(true);
            }
        }
        else
        {
            // Deselect the row.
            grid.get_masterTableView().get_dataItems()[nCount].set_selected(false);
        }
    }
}
</script>

The latest version of RadGrid provides a flexible client-side API than previous version. You can also try the following code in order to archive same functionality.

JavaScript:

<script type="text/javascript">
function fnColumnHeaderChecked(sender, args)
{
    var columnChecked = true;
    var grid = $find('<%=RadGrid1.ClientID %>');
    if( columnChecked == true )
    {
        grid.get_masterTableView().selectAllItems();
    }
    else
    {
        grid.get_masterTableView().clearSelectedItems();
    }
}
</script>

Hope this helps.
