Hi,
I have a radtreeview that has a context menu.  I would like to hide the entire context menu based upon the value of the node attribute.
I can kind of achieve this by hiding individual menu items, however a small animation is still shown even if no menu items are displayed.
I would like to do this client side if possible.
Thanks.

hi 

How do i make the navigate url to link to a section of a page? I try using the code below but is not working. Here is what i want to accomplish using RadPanelBar instead of anchor tag http://www.echoecho.com/htmllinks08.htm. Thanks a lot

<telerik:RadPanelItem runat="server" Text="Customers">
            <Items>
                <telerik:RadPanelItem runat="server" NavigateUrl="#customer" Text="View Customers">
                </telerik:RadPanelItem>
            </Items>
</telerik:RadPanelItem>

 

 <div class="panel panel-primary" style="margin-right:5px;margin-top:2px">
         <div class="panel-heading" id="customer">
            <h3 class="panel-title">Customer</h3>
         </div>
          <div class="panel-body">
            <h4>How to use View Customers</h4>
              <hr />
              <p></p>
          </div>
</div>

When trying to use the RadGridDesigner with the grid webpart I get a 403 error. When I look at the event viewer application log I see the following error. Not sure how to fix this.

I have a grid that invokes the edit appointment functionality, but on an appointment that is a series, I'd like show the Edit occurence/series dialog option from server side.

 

  this.radActivity.ShowAdvancedEditForm(apptToEdit, true);

<telerik:GridTemplateColumn HeaderText="Quantity" UniqueName="Quantity">
    <ItemTemplate>
        <asp:Label ID="lblQuantity" runat="server"
            Text='<%# DataBinder.Eval(Container.DataItem, "Quantity") %>'>
        </asp:Label>
    </ItemTemplate>
    <EditItemTemplate>
        <telerik:RadNumericTextBox ID="txtQuantity" runat="server" DataType="System.Decimal"
            Type="Number" NumberFormat-DecimalDigits="4" />
    </EditItemTemplate>
</telerik:GridTemplateColumn>

 

 

I've made a RadGrid with EditMode="Batch" that is bound to a dataset. I need to create some GridTemplateColumns, such as the above. 3 questions...

 

1) In checking out examples online, at times I've seen Eval above as it is...

Text='<%# DataBinder.Eval(Container.DataItem, "Quantity") %>'>

...but other times like this...

Text='<%# Eval("Quantity") %>'>

The latter is cleaner, but wondering if the first is recommended for some reason. Or are they identical?

 

2) Also, at times I've seen in the GridTemplateColumn header the attribute DataField and DataType, such as...

DataField="Quantity"

DataType="System.Double"

... but again, not always. Are they necessary? Or does it depend on the situation?

 

3) Do I need to somehow Bind the field to the EditItemTemplate portion?

 

Thanks for the help!

Hi,
I am using the radinput manager with the "<Validation IsRequired="True" />" property to force certain textboxs to be required.

This works well displaying a warning symbol on the relevant textbox and a red outline if the box is left empty.

My issue is I also have a combobox with a required field validator, but this doesn’t indicate the input has no value selected in the same style as the other textbox controls giving an inconsistent interface.

Could this functionality be added to the standard combobox (obviously only IsRequired functionality) or full functionality if using a RadCombobox as this effectively contains a textbox.

This problem vexxed me for a short while, because the message returned is pretty generic and the stack trace didn't really hep me pinpoint the issue.

I eventually isolated this (I thought) to a RadAjaxPanel control I had declared:

<telerik:RadAjaxPanel ID="radPanel" runat="server" HorizontalAlign="NotSet" 
    LoadingPanelID="radLoadingPanel">
        <asp:DropDownList ID="ddlTierID" runat="server" DataSourceID="BusinessUnitTypesDataSource"
            DataTextField="Name" DataValueField="RowID" TabIndex="7">
        </asp:DropDownList>
</telerik:RadAjaxPanel>

If I replaced this code block with the Microsoft flavor (which is what I'd tried to convert over to Telerik) like this:

<asp:UpdatePanel UpdateMode="Conditional" runat="server">
    <Triggers>
        <asp:AsyncPostBackTrigger ControlID="ddlUserRole" EventName="SelectedIndexChanged" />
    </Triggers>
    <ContentTemplate>
        <asp:DropDownList ID="ddlTierID" runat="server" DataSourceID="BusinessUnitTypesDataSource"
            DataTextField="Name" DataValueField="RowID" TabIndex="7">
        </asp:DropDownList>
    </ContentTemplate>
</asp:UpdatePanel>

then the page runs fine. However, I didn't understand why the Telerik panel should cause an issue, until I found this article:

http://www.telerik.com/help/aspnet-ajax/troubleshooting.html

At the top of the page containing the panel, I had this seemingly innocuous JavaScript snippet that simply set the focus to the first field on the form:

<script type="text/javascript">
    function pageLoad()
    {
        $get('<%=txtUserName.ClientID %>').focus();
    }
</script>

Based on the Telerik article, above, I wrapped this snippet in a RadCodeBlock and then the RadAjaxPanel code worked fine!

Hope this helps someone else!
