Hi,

i have two problems with a grid in batch editing mode and RadDropDownList inside the grid. I set the databinding in code behind for both. The databinding of the RadDropDownList  is in the prerender section of the grid:

protected void rgPmls_PreRender(object sender, EventArgs e)
{RadDropDownList rcbCarrier =    (RadDropDownList)rgPmls.FindControl(rgPmls.MasterTableView.ClientID + "_CarrierId").FindControl("rcbCarrier");

Carrier getCarrier = new Carrier();
rcbCarrier.DataSource = getCarrier.GetCarrier();
rcbCarrier.DataTextField = "Carrier";
rcbCarrier.DataValueField = "CarrierId";
rcbCarrier.DataBind();
}

Here is the grid:

<telerik:RadGrid ID="rgPmls" runat="server" AllowAutomaticDeletes="True"
           AllowAutomaticInserts="True" Skin="Windows7" OnItemInserted="rgPmls_ItemInserted"
           OnItemUpdated="rgPmls_ItemUpdated" AllowAutomaticUpdates="True" AllowPaging="True"
           AutoGenerateColumns="False" Width="1650px" OnBatchEditCommand="rgPmls_BatchEditCommand" Culture="de-DE"  OnItemCommand="rgPmls_ItemCommand" OnNeedDataSource="rgPmls_NeedDataSource" OnPreRender="rgPmls_PreRender">
           <MasterTableView CommandItemDisplay="Top" DataKeyNames="LoadingscheduleId"
               HorizontalAlign="NotSet" EditMode="Batch" AutoGenerateColumns="False">
               <BatchEditingSettings EditType="Cell" />
<Columns>
<telerik:GridTemplateColumn HeaderText="Reeder" HeaderStyle-Width="110px" UniqueName="CarrierId" DataField="CarrierId">
    <ItemTemplate>
        <%# Eval("Carrier") %>
    </ItemTemplate>
    <EditItemTemplate>
        <telerik:RadDropDownList runat="server" ID="rcbCarrier" DataValueField="CarrierId"
            DataTextField="Carrier" Width="100">
        </telerik:RadDropDownList>
    </EditItemTemplate>
    <HeaderStyle Width="110px" HorizontalAlign="Center" />
</telerik:GridTemplateColumn>
</Columns>
<ClientSettings AllowKeyboardNavigation="true">
<Scrolling AllowScroll="True" FrozenColumnsCount="3" UseStaticHeaders="True" />
</ClientSettings></telerik:RadGrid>

The databinding works fine and I can see all the items in the RadDropDownList. But I have the problems when I update the grid:

First problem: When I update the grid in batch editing mode all works fine at the first time and i get the selectedvalues of the RadDrobDownList. When I update
the grid a second time with a new seleted item, I get no value back.

Second problem: When the RadDropDownList has only one item, I also get no value back

What do I forget?

Thx for help.

Hi,
I am evaluating Telerik to replace some controls we have for our project.

We are using a RadSearchBox, and when the user select an entry, based on the entry different things can happen.
One of them is that a popup open with a label inside displaying the user entry name.

So far I have the following

ASP
C#

Any help would be welcomed.

Does Telerik provide Radar Chart for ASP.Net Web.
I am checking this post www.telerik.com/forums/radar-chart-update but I thing it showing that it does not support for ASP.Net web, but supporting for WPF, Silverlight etc
.
Can anybody help me.

I have a radgrid that displays number values'

Is it possible to scan the entire grid and highlight all cells who's value is great than say 100?

Is there a way to disable the text box visually and from editing using javascript? I was using the radComboBox and it had the .disable() & .enable() functions. I see AutoCompleteBox has the set_enabled(i) however the control appearance is still enabled.

Hello all..

I have the following peculiar problem.

aspx
<telerik:RadWindowManager ID="RadWindowManager1" runat="server" EnableShadow="true">
          </telerik:RadWindowManager>

<telerik:RadNotification ID="n1" runat="server" Text="" Position="Center"
    AutoCloseDelay="5000" Width="450" Title="" KeepOnMouseOver="true"
    EnableRoundedCorners="true" Animation="Resize" ContentIcon="warning"
    AnimationDuration="700" TitleIcon="none" Font-Size="12px" Font-Bold="True"
    ShowCloseButton ="true">
</telerik:RadNotification>

vb
  Protected Sub grdTenders_DeleteCommand(sender As Object, e As GridCommandEventArgs)

     ... code to set the value of <res> below

    If res = 1 Then
      n1.Title = "Error Deleting"
      n1.Text = "Cannot delete this tender. It has been sent out to at least 1 Manufacturer!"
      n1.Show()
      Exit Sub
    End If

...and further down

Protected Sub grdTenDetails_ItemCommand(sender As Object, e As GridCommandEventArgs)

     ... again code to set the value of res below

    If res = 1 Then
      n1.Title = "Error Editing"
      n1.Text = "Cannot Edit this tender. It has been sent out to at least 1 Manufacturer!"
      n1.Show() 
        e.Canceled = True
        Exit Sub
      End If


The first notification works fine.
The second time the notification should be shown (on the second sub) the window pops up without title or text!
It is functional, but the values for <title> and <text> remain the default ones (empty)
I stopped the code in n1.Show() and the values are correct. Then I continue the code and still no text/title.

I even tried to add another notification (r2) on the page and changed the code on the second sub, but still the second window comes up empty!


Any information would be appreciated...

Hi,

  I am highlighting first menu item from codebehind by: RadMenu1.Items(0).HighlightPath(). That works as expected.

However, when i am trying to do the same from Javascript i struggle.

I tried:

  function RadMenu1_OnClientItemClicking(sender, eventArgs) {     

          var item = eventArgs.get_item();      
          item.set_selected(true)

This results in both menu items highlighted. Additional problem that when i click outside menu, second item of menu looses it highlight state, but first item stays highlighted.

Another way i tried

         var menu = $find("<%= RadMenu1.ClientID %>");
          var firstItem = menu.get_items().getItem(0).set_selected(true);
          var secondItem = menu.get_items().getItem(1).set_selected(false);
          menu.commitChanges();

Kinda same issues.

Please advice

Hello all,

I have:

in .aspx
 <telerik:RadWindowManager ID="RadWindowManager1" runat="server" EnableShadow="true">
          </telerik:RadWindowManager>
  <script type="text/javascript">
    function confirmCallbackFn(arg) {
      if (arg) { //the user clicked OK
      __doPostBack("<%=HiddenButton.UniqueID %>", "");
      }
    }
    </script>
 
<div id="divMain" style="position: relative; top: 0px;">
<asp:Button ID="HiddenButton" Text="" OnClick="HiddenButton_Click"
  runat="server" Visible="False" />
....



in the code (inside a delete event of a radgrid)
RadWindowManager1.RadConfirm("Delete this Tender?", "confirmCallBackFn", 330, 180, Nothing, "Confirm")

...and

Protected Sub HiddenButton_Click(sender As Object, e As System.EventArgs) Handles HiddenButton.Click
...the actual code which deletes the Tender from the database
End Sub


While the RadConfirm does get executed, the radconfirm window is not appearing on the page.

Could you please point out my mistake?

Thanks

Thank you very much

I have a RibbonBarSplitButton containing three RibbonBarButton items. If I set the SplitButton to enabled and the child Buttons to disabled, the SplitButton uses the disabled image, even though the control itself is enabled.

If I dynamically set the first button to enabled, the SplitButton image is not updated and still shows as disabled. After enabling the child button, I have to disable the SplitButton and then re-enable it for its image to change.

Is this a bug or am I missing something in how the controls are supposed to interact?

I am on Q2 2014 SP1
