I have a radgrid with a CommandItemTemplate with three buttons. When a user clicks the 'Add Run' button it triggers the InitInsert.
After the user enters the data and clicks the check image button to insert the data, a check is performed in the RadGrid.InsertCommand to see if the user entered a value in the Number column that already exists.  If the Number does exists the user needs to be prompted and asked if they want to renumber the already existing rows and insert this one, or cancel.

I need to be able to display a message and capture the result and either exit the sub or do other processing.


Some script attempts

       //function confirmCallBackFn(arg) {
        //    radalert("<strong>radconfirm</strong> returned the following result: <h3 style='color: #ff0000;'>" + arg + "</h3>", 350, 250, "Result");
        function RadResequence(sender, args) {
            var callBackFunction = Function.createDelegate(sender, function (shouldSubmit) {
                if (shouldSubmit) {
            var text = "<%= ResequenceAssignments %>";;
            radconfirm(text, callBackFunction, 500, 100, null, "Confirm Close");

        function RadResequence2() {
            var confirmValue = document.createElement("INPUT");
            confirmValue.type = "hidden";
   = "confirmValue";
            if (confirm("Do you want to Resequence? If you click yes, blah blah blah")) {
                confirmValue.value = "OK";
            else {
                confirmValue.value = "Cancel";

THE RADGRID.INSERTCOMMAND SUB. I'm just worried about the For next loop checking for a duplicate value in the radgrid then displaying a message and capturing the result.


    Private Sub rdgrdDetailRS_InsertCommand(sender As Object, e As GridCommandEventArgs) Handles rdgrdDetailRS.InsertCommand
        If TypeOf e.Item Is GridEditableItem Then
            Dim insertedItem As Telerik.Web.UI.GridEditableItem = CType(e.Item, Telerik.Web.UI.GridEditableItem)
            Dim newValues As Hashtable = New Hashtable
            e.Item.OwnerTableView.ExtractValuesFromItem(newValues, insertedItem)
                Dim strNewValue As String = newValues("Assigned").ToString
                Dim strID2 As String = newValues("Number").ToString
                If Len(strID2) <> 2 Then
                    rwmAdministration.RadAlert("Number must be Two digtis Only.", 500, 100, "Add Error", "null")
                    Exit Sub
                End If
                If Not IsNumeric(strID2) Then
                    rwmAdministration.RadAlert("Number must be a numerical value.", 500, 100, "Add Error", "null")
                    Exit Sub
                End If
                For Each row In rdgrdDetailRS.Items
                    If row.Cells(4).text = strID2 Then
                        'TODO need to figure out how to ask the user if they want ot resequence
                        ' rwmAdministration.RadAlert("Sorry, Run number " & strID2 & " already exists. Do you want to resequence", 500, 100, "Add Error", "null")
                        '  rwmAdministration.RadConfirm("Server radconfirm: Are you sure?", "confirmCallBackFn", 330, 180, Nothing, "Server RadConfirm", Nothing)
                        ' rwmAdministration.RadConfirm("Do you want to resequence. Are you sure?", "RadResequence", 330, 180, Nothing, "Server RadConfirm", Nothing)
                        rwmAdministration.RadConfirm("Do you want to resequence. Are you sure?", "RadResequence2", 330, 180, Nothing, "Server RadConfirm", Nothing)
                        Dim confirmValue As String = Request.Form("confirmValue")
                        If confirmValue = "Ok" Then
                            Dim value As String = "Ok"
                            Dim value As String = "Cancel"
                        End If
                        ' Exit Sub
                    End If

                Dim cmd As New SqlCommand
                cmd.CommandType = CommandType.StoredProcedure
                cmd.CommandText = "InsertDetailRS"
                cmd.Parameters.Add(New SqlParameter("@DateCode", SqlDbType.Date)).Value = BasicUtil.GetQueryString 'CType(strID, Date)
                cmd.Parameters.Add(New SqlParameter("@Number", SqlDbType.VarChar)).Value = CType(strID2, String)
                cmd.Parameters.Add(New SqlParameter("@LastModifiedBy", SqlDbType.NVarChar)).Value = ADUtil.GetCurrentUser
                ' cmd.Parameters.Add(New SqlParameter("@ID", SqlDbType.Date)).Value = BasicUtil.GetQueryString
                cmd.Parameters.Add(New SqlParameter("@Assigned", SqlDbType.NVarChar)).Value = strNewValue
                Dim bolOk As Boolean = SQLUtil.ExecuteNonQuery(cmd, BasicUtil.csAppDB)
                If bolOk Then
                    rwmAdministration.RadAlert("There was an error trying to insert a New Run record.", 500, 100, "Update Error", "null")
                    e.Canceled = True
                End If
                ' Else

            Catch ex As Exception
                e.Canceled = True
                rwmAdministration.RadAlert("There was an error trying to insert a New Run record.", 500, 100, "Update Error", "null")
            End Try
        End If

I did the hidden button thing.


Create   this function

function confirmCallbackFn(arg) {
if (arg) //the user clicked OK
__doPostBack("<%=HiddenButton.UniqueID %>", "");

Add a Hidden button, call it what you want

<asp:Button ID="HiddenButton" Text="" Style="display: none;" OnClick="HiddenButton_Click" runat="server" />


Display a RadConfirm in the middle of the code that is processing. Call the javascript function confirmCallbackFn. You have to remember all your server code will run until completion before the message gets displayed.

rwmAdministration.RadConfirm("The Run Number Already Exists, Do you want to Resequence?", "confirmCallbackFn", 300, 200, Nothing, "Confirm")


If the user clicks ok then the Click event gets called otherwise processing stops.

Protected Sub HiddenButton_Click(sender As Object, e As System.EventArgs) Handles HiddenButton.Click
       'Handle the response here and execute the rest of the logic

End Sub
