Get radgrid data from javascript

[Angie]

Here is my grid:

 <telerik:RadGrid runat="server" ID="radTableColumns" AutoGenerateColumns="false" AllowMultiRowSelection="true" >
            <ClientSettings>
                <Selecting AllowRowSelect="true" />
            </ClientSettings>
            <MasterTableView>
            <Columns>
                <telerik:GridClientSelectColumn HeaderStyle-Width="40px"   />
               <telerik:GridBoundColumn DataField="column_name" HeaderText="Column Name" />
                <telerik:GridBoundColumn DataField="column_type" HeaderText="Column Type" />
            </Columns>
            </MasterTableView>
             </telerik:RadGrid>

It's in a radwindow, so I need to be able to loop through the grid and compile a list of items where the checkbox is checked. 

I saw the example where you can set it to postback on the check changed event, but I'd prefer not to have to rebuild the string and postback everytime something is checked.

Is there anyway to do a loop through in javascript?

Thanks.

Hi Angie,

Here is the javascript code to loop through the selected rows in a Grid.

ASPX:

 <INPUT onclick="GetSelectedNames();"  type="button" value="Get selected rows contact names">

JS:

  function GetSelectedNames()
 {
   var grid = $find("<%=RadGrid1.ClientID %>");
   var MasterTable = grid.get_masterTableView();

   var selectedRows = MasterTable.get_selectedItems();
   for (var i = 0; i < selectedRows.length; i++)
   {
     var row = selectedRows[i];
     var cell = MasterTable.getCellByColumnUniqueName(row, "CategoryID")
    //here cell.innerHTML holds the value of the cell
   }
 }

Thanks

I tried to use

grid.get_masterTableView();

but it gives me object not found error.

Please let me know what i can do to get the all items from radgrid. When i check the DLL file for Radgrid it shows version 5.1.5.

Not sure if the above function is valid for this version . Please help

Thank you
