asp:LinkButton ID="LinkButton1" runat="server" OnClick="lnkbtnAddSlot_New_Click"

Width="97px" CssClass="sf-inputsLinkButton" OnClientClick="return AddSlot_New()">Add Slot_New</asp:LinkButton>

OnClientClick I want to access the no. of rows in radgrid and the values of the cells.

I used

var gvWorkingHours = $find("<%= gvWorkingHours_New.ClientID %>").get_masterTableView();

This is becoming null always.

for (var i = 0; i < gvWorkingHours.get_masterTableView().get_dataItems().length; i++)

{

var row = Rows[i];

var textbox1 = row.findControl("txtSlotName"); //

}

Please suggest solution.

Below is the entire source  code.
