Hi,

How can I get the selected cell value from this event in JS? Seems like this should be documented in the manual, but I am not seeing it.

I tried this (after looking at other threads):

function Test_OnCellSelected(sender, args) {
    var gridDataItem = args.get_gridDataItem();
    var cell = gridDataItem.get_cell();
}

But i get "Microsoft JScript runtime error: 'undefined' is null or not an object" for the get_cell().

Thanks

Hi Kernelk,

Please try the below code snippet to access the cell selected values.

ASPX:
<ClientSettings Selecting-CellSelectionMode="MultiCell">
    <ClientEvents OnCellSelected="OnCellSelected" />
</ClientSettings>

JS:
<script type="text/javascript">
    function OnCellSelected(sender, eventArgs) { 
        var columnName = eventArgs.get_column().get_uniqueName();
        var data = eventArgs.get_gridDataItem().get_cell(columnName);
        alert(data.innerHTML);     //Get the cell value
    }
</script>

Hope this helps.

Thanks,
Princy

Thanks Princy!

I have another follow-up question:

Is it possible from the JS OnSelectedCell to get the actual index of the row that would correspond to the index from the csharp side of RadGrid.MasterTableView.Items[selectedRowIndex] ?

We are using grid paging and args.get_row().rowIndex appears to be relative to the grid page.

Thanks again.

Hi Kernelk,

I'm not clear about your requirement,I guess you want to get the selected cell row index on the CellSelected event.Please try the below code snippet.If this doesn't help,please elaborate on your requirements.

JS:
<script type="text/javascript">
    function OnCellSelected(sender, eventArgs) { 
        var rows = eventArgs.get_gridDataItem();
        var columnName = eventArgs.get_column().get_uniqueName();
        var data = rows.get_cell(columnName);
        alert(data.innerHTML);         
        var rowIndex = rows.get_itemIndexHierarchical(); //get the Row Index
        alert(rowIndex);
    }
</script>

Thanks,
Princy

Hi Princy,

To clarify, i want the index of the item as i would find it from RadGrid.MasterTableView.Items[selectedRowIndex] on the c# side. I am aware of the method you provided, but the index returned appears to be relative to the "grid page" (we are using paging of the grid).

So, if i am on grid page 10, the first row index returns 0 instead of the index of the item relative to the entire list of items.

Thanks,

Hi Kernelk,

The default behavior of the row index is based on the paging,in each page the index starts from 0.If you want to identify the row being selected,the best method is to use DataKeyNames.Please try the below code snippet.

ASPX:
<MasterTableView DataKeyNames="OrderID" ClientDataKeyNames="OrderID">

JS:
<script type="text/javascript"
    function OnCellSelected(sender, eventArgs) {
        var data;
        var rows = eventArgs.get_gridDataItem();
        var columnName = eventArgs.get_column().get_uniqueName();
        data = rows.get_cell(columnName);    
        alert(data.innerHTML);//Selected cell value
        var rowIndex = rows.getDataKeyValue("OrderID");//Selected rows DataKeyValue
        alert(rowIndex);
    }
</script>

Thanks,
Princy
