Hi,

I have a RadGrid and "Next" button in a user control and the user control is one of the wizard steps. The website is built in Sitefinity CMS. 

I have a requirement to validate no.of records in RadGrid and display a message to user if there are no records. To put in another way, something like RequiredFiledValiation: the user should not be able to proceed to Next step if there are 0 records.  

I tried the following. 

1.  

  protected void RadGrid1_PreRender(object sender, EventArgs e) 
    { 
        RadGrid1.MasterTableView.AllowPaging = false; 
        RadGrid1.Rebind(); 
        Label1.Text = RadGrid1.MasterTableView.Items.Count.ToString(); 
        RadGrid1.MasterTableView.AllowPaging = true; 
        RadGrid1.Rebind(); 
    } 

2. Below code in ItemDataBound 

if TypeOf e.Item is GridFooterItem Then 

        Label1.Text = RadGrid1.MasterTableView.Items.Count.ToString(); 
 End If

3.  In Page_Load():    Label1.Text = RadGrid1.MasterTableView.Items.Count.ToString(); 

Nothing worked, the count is always 0.

Please suggest me something definite.

Regards,

Siva Karthik

Hi,

I have a Vertical RadMenu on master page that gets populated from a sitemap. I am using the Silk skin as the base skin with my own color modifications.

I want to use it as a NotificationMenu.

Example: People can add products by using a project registration Page. ProductRegistration.aspx. At the Menu Item there will be an Item called "New Products Registered". I want to add onto this menu item a type of count indicator (with small gray circle background ) that Counts the New Products out of the database table and displays it on the menu item. Of course if you click on the menuItem you must be redirected to the Page containing list of new products added (Radgrid)

Is there a better control to use or a better way to do this?

 <telerik:RadMenu ID="NotificationsMenu" runat="server" item DataSourceID="smNotificationsMenu" EnableEmbeddedSkins="False" 
                                    RenderMode="Lightweight" Skin="LeftMenuSkin"
                                    ShowToggleHandle="True" Flow="Vertical">

Kind Regards

Hi, i have a RadDatePicker in EditForm in RadGrid.

The column in RadGrid consist of EditButtonColumn, Name, StartDate, EndDate.

when i click Edit, it shows error:

Sys.WebForms.PageRequestManagerServerErrorException: Specified cast is not valid.

I assume this is because the value StartDate and EndDate is empty/null.

my code to assign the value to RadDatePicker is like this:

How to set RadDatePicker, when there's no value, shows no error. And if there's a value, the value of StartDate and EndDate will set to TextField and SelectedDate in RadDatePicker 

Thank you very much

Hi Telerik,

               I have a Problem With the Export to excel. In my case, I created the multiple radgrids dynamically from Code - behind and add it into the Placeholder. I have enabled the default Export to excel button for all grids. I haven't use any ajax panels, but I use Update panel. When i click the default Export to excel button, all grids are invisible and excel did not generated.

 Code:

   Dim dset As DataSet
        Dim col_count As Integer

        For i As Integer = 0 To c - 1

            Dim radgrid1 As New Telerik.Web.UI.RadGrid
            radgrid1.ID = "RadGrid" & i
            radgrid1.ExportSettings.Excel.Format = GridExcelExportFormat.Html
            radgrid1.MasterTableView.CommandItemDisplay = GridCommandItemDisplay.Top
            radgrid1.MasterTableView.PageSize = "10"
            radgrid1.MasterTableView.CommandItemSettings.ShowExportToExcelButton = True
            radgrid1.MasterTableView.DataKeyNames = New String() {"employee_id"}
            radgrid1.ExportSettings.ExportOnlyData = True

            radgrid1.ExportSettings.FileName = Pub_dset.Tables("tblCount").Rows(i).Item("sub_heading")
            radgrid1.MasterTableView.Caption = "Sub Heading - " & Pub_dset.Tables("tblCount").Rows(i).Item("sub_heading")
            radgrid1.AutoGenerateColumns = False
            radgrid1.ClientSettings.ClientEvents.OnCommand = "onRequestStart('this')"
            dset = DAL.details(9, 4, "", "", "", 0, 0, 0, CDate(Now), CDate(Now), CDate(Now), "", "", "", 0, "", "", 0, 0, i, "", 0, "", 0, 0, "", 0, CDate(Now), "tblBind")
            col_count = dset.Tables("tblBind").Columns.Count
            col_count = dset.Tables("tblBind").Columns.Count

            For j As Integer = 0 To dset.Tables("tblBind").Columns.Count - 1
                Dim Bcol As New GridBoundColumn
                Bcol.DataField = dset.Tables("tblBind").Columns(j).ColumnName
                Bcol.UniqueName = dset.Tables("tblBind").Columns(j).ColumnName
                Bcol.HeaderText = dset.Tables("tblBind").Columns(j).ColumnName
                Bcol.ShowFilterIcon = True
                Bcol.AllowFiltering = True
                Bcol.AllowSorting = True
                Bcol.ItemStyle.Wrap = False
                radgrid1.MasterTableView.Columns.Add(Bcol)
                If Bcol.UniqueName = "employee_id" Or Bcol.UniqueName = "emp_no" Then
                    radgrid1.MasterTableView.GetColumn(Bcol.UniqueName).Display = False
                End If
                If Bcol.DataField = "emp_name" Then
                    Bcol.HeaderText = "Employee Name"
                End If
            Next
            radgrid1.DataSource = dset.Tables("tblBind")

            radgrid1.Rebind()
            PlaceHolder1.Controls.Add(radgrid1)
            PlaceHolder1.Controls.Add(New LiteralControl("<br><br>"))
        Next

Please help me resolve this...

its very urgent...

Hello

      I need to set the item cell read only in batch edit mode. I found a solution that handles the OnBatchEditOpening event at client side. But this property is not supported because the telerik version is 2013.02.0611.40. And I cannot update it by myself due to corporation's manner. Is there any other way to achieve my requirement?

Thanks.

Best regards

So there shouldn't be too much going on in the page I'm having the issue with.

 The cause of this issue was a recent upgrade to the latest (or close to) telerik dlls. Prior to that this issue was not occurring and no code has changed other than the telerik upgrade. We are using DotNetNuke as well.

 Basically, there is an asp:panel that contains a few search filters, namely an id search textbox field. When the search button is clicked, the value of the textbox is read and the panel's Visible property is set to false and another panel's visibility is set to true (to show the results). The user may click a "return" button which does another post back that sets the initial panel's visibility back to true and the results panel back to false.

 After this happens the RadTextBox that contains the id search will continually postback the previous search value even though the user had entered something else. The textbox is clearly posting the correct value when inspected with chrome's debugging tools (via network request capture you can view the form data).

 To verify this is specific to RadTextBox, I replaced the control with a normal asp:TextBox with no other changes and it worked properly as expected.

 Can I get some guidance as to what may be going wrong here? I've done hours of debugging and trying different things and have not figured out the cause.
