Javascript to get number of checkboxes checked in radgrid

[LUCKY]

Hi,

I have a GridClientSelectColumn in my rad grid. In my CommandItemTemplate I have a link button called view.

Now wat i want is on click of the view button, I need to iterate through the rows in my grid and check that only one checkbox is selected in the GridClientSelectColumn.

Hi,

you can simply check whether an item is selected or not. This may look something like this:

.aspx

<telerik:RadGrid
         ID="RadGrid1" runat="server" DataSourceID="AccessDataSource1" GridLines="None"
         AllowMultiRowSelection="true">
            <ExportSettings>
                <Pdf FontType="Subset" PaperSize="Letter" />
                <Excel Format="Html" />
                <Csv ColumnDelimiter="Comma" RowDelimiter="NewLine" />
            </ExportSettings>
            <MasterTableView AutoGenerateColumns="False" CommandItemDisplay="Top" CurrentResetPageIndexAction="SetPageIndexToFirst"
                DataKeyNames="CustomerID" DataSourceID="AccessDataSource1" Dir="LTR" Frame="Border"
                TableLayout="Auto">

                <CommandItemTemplate>
                <asp:Button runat="server" ID="button1" OnClientClick="getSelected();" Text="getSelected" />
                </CommandItemTemplate>

.Js

 <script type="text/javascript">

        function getSelected()
        {
        var RadGrid1 = $find("<%=RadGrid1.ClientID %>");
        alert("Number of selected items : " + RadGrid1.get_masterTableView().get_selectedItems().length);
        }

        </script>

I hope this information helps.

All the best,

hi ,
i have a rad grid with a template column with a checkbox

1) i want to get the number of rows in a rad grid in client side and check how many checkbox are selected
if selected need to execute some server side  code
else need to return an alert box saying 'please select a id to remove'

2) i have a scenario where a user will add a row to the rad grid and once added that newly added row has to be slected.
i want to do this on client or server side

function getSelected()

{

var RadGrid1 = $find("<%=RadGrid1.ClientID %>");

alert("Number of selected items : " + RadGrid1.get_masterTableView().get_selectedItems().length);

}

i tried this but the return value is only 0

Hello ratheesh,

Basically, the approach which I mentioned previously is applicable if checking the checkbox will trigger some selection in the control.
If this is not the case, you can reference the cell which would contain the checkbox, and then the checkbox itself to get its value.
Additionally, you can preselect the newly added item in the grid, in the PreRender server side handler, by Accessing RadGrid1.MasterTableView.Items[x], where x is the index of the newly entered item.
I hope this helps.
