RadGrid - Delete Confirm JavaScript and Get Values of the DataField of the ClientDataKeyNames

[Chi Ming]

Hello everyone,

i need your help for getting the value of the DataField from ClientDataKeyNames array of the MasterTable and even without AllowRowSelect = "True" 
All I need is to CLICK BUTTON ONLY WITHOUT AllowRowSelect = True 
Once I click "Remove Location" button, I am still getting error that we don't get any values from ClientDataKeyName.  

In UserControl 

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">
        <script type="text/javascript">
            function OnClientClickingApprovedLocations(sender, args) {
                var callBackFunction2 = Function.createDelegate(sender, function (argument) {
                    if (argument) {
                        this.click();
                    }
                });

                var Master = $find("<%=rgRequestorlocations.ClientID %>").get_masterTableView();
                var SelectedItem = Master.get_selectedItems()[0];

                var location_name = SelectedItem.getDataKeyValue("location_name"); // get the DataKeyValue of selected item
                var role = SelectedItem.getDataKeyValue("role");
                var duty = SelectedItem.getDataKeyValue("duty");


                if (duty == "P") {
                    if (role == "Privacy Officer") {

                        roletext = "Are you sure you want to remove this role location?";
                        radconfirm(roletext, callBackFunction2, 300, 100, null, "Delete");
                        args.set_cancel(true);
                    }
                    else {
                        roletext = "Please confirm the Primary " + role + " for " + location_name + " will be removed " + "" + "?";
                        radconfirm(roletext, callBackFunction2, 300, 100, null, "Delete");

Hello Chi,

Please run the attached web site which demonstrates a similar functionality and let me know if it helps you. The implemented approach does not depend on the selected item and the application will work as expected even with disabled selection:

<ClientSettings>
    <Selecting AllowRowSelect="false" />
</ClientSettings>

Hope this helps.

Eyup
