radgrid EnableDragToSelectRows serverside

[Lukrs]

Hi,

I'm trying to select rows and handle them serverside. I would like to trigger a postback on multiple row selecting by drag. I managed to do a postback with this code :

function RowSelected(row, eventArgs) {
        alert(row);
        __doPostBack('<%=skupineGrid.ClientID %>');

    }


It is triggered here <ClientEvents OnRowSelected="RowSelected" />.

Now I would like to do an update in the database for selected rows.

 foreach (GridDataItem item in skupineGrid.SelectedItems)
        {
          item.Selected = true;
          // bla bla
        }

How can I achive this?

Hi,

Try accessing the selected rows in the Prerender event of the Grid.

CS:

protected void RadGrid1_PreRender(object sender, EventArgs e)
    {
        foreach (GridDataItem dataitem in RadGrid1.SelectedItems)
        {

        }

    }

Hi,

This doesn't work.

The codebehind in preRender doesn't get SelectedItems.

Hi Luka,

Give a try with the following code snippet in the PreRender event and see whether it works

CS:

protected void RadGrid1_PreRender(object sender, EventArgs e)

{

foreach (GridDataItem dataitem in RadGrid1.MasterTableView.Items)

{

if (dataitem.Selected)

{

// access the selected items here

}

}

}

Thanks

Hi Princy,

I think we do not understand each other quite right.

The thing is:

I call this javascript function on client side <ClientEvents OnRowSelected="RowSelected" />

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server"> 
<script type="text/javascript">
    function RowSelected(row, eventArgs) {
        alert(row);
        __doPostBack('<%=skupineGrid.ClientID %>');

    }
</script>
     </telerik:RadCodeBlock>


I click on a row, or select multiple rows with <Selecting AllowRowSelect="True" EnableDragToSelectRows="true" /> property set to true.

The postback is triggered, but on preRender (protected void RadGrid1_PreRender(object sender, EventArgs e) ) there are no selected items.

Basicly my idea is to select rows clientside, and maintain selected rows after postback. I found tutorials that have a button, which postbacs and the rows stay selected. With my javascript I posted, RowSelected, this simply doesn't happen.

Any Ideas why?

thanks,
LP, Luka
