===============================

 

CODE in .aspx

<script>

         function DeleteConfirm(sender, args) {

Hi

I have searched the forums and can't see anything that seesm to match my case.

I want to hide a column based on a value set in a settings table.  No problem getting the
setting value as true or false, but I can't make the column hidden.

Columns are not autogenerated and the column in question is declared like this
<telerik:GridBoundColumn DataField="StockQuantity" DataType="System.Int16"   
            HeaderText="Stock" SortExpression="StockQuantity"   
            UniqueName="StockQuantity">  
</telerik:GridBoundColumn> 

How can this be made visible/invisble from the code behind?
I have tried this below but I think it is applicable only to autogenerated columns.. Anyway it does not do anything.
Protected Sub RadGrid1_ColumnCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridColumnCreatedEventArgs) Handles RadGrid1.ColumnCreated  
 
        If e.Column.UniqueName = "StockQuantity" Then  
            e.Column.Visible = False 
        End If  
 
    End Sub  
 

Thanks for help here!

I have a RadToolBar (RadToolBar1) placed inside a RadGrid. When I use Tab to focus a RadToolBarButton and press Enter, the server-side event doesn’t fire (e.g.,  CommandName="InitInsert"). How can I make pressing Enter trigger the button’s server-side event?

I've tried this code, but it was not working.

Keyboard Support

function pageLoadHandler() {
    var buttonList = document.querySelectorAll('.RadToolBar .rtbUL .rtbItem');

    if (buttonList) {
        buttonList.forEach((button) => {
            button.addEventListener("keydown", (e) => {
                if (e.code === "Enter") {
                    button.click();
                }
            })
        })
    }
}

Sys.Application.add_load(pageLoadHandler); 
Below is my radgrid

I try to follow the example in https://demos.telerik.com/aspnet-ajax/orgchart/examples/applicationscenarios/drilldowntoviewdetails/defaultvb.aspx?show-source=true but if I run the code and click on an icon for drill-down I get the error at the line "If e.SourceNode.ID <> "1" Then":

Telerik.Web.UI.OrgChartDrillDownEventArguments.SourceNode.get returned Nothing.

The code is:

  Private Sub RadOrgChart2_DrillDown(sender As Object, e As Telerik.Web.UI.OrgChartDrillDownEventArguments) Handles RadOrgChart2.DrillDown
      If e.SourceNode.ID <> "1" Then
          Dim item = New OrgChartGroupItem()
          e.SourceNode.Renderer.Controls.Remove(e.SourceNode.Nodes.Renderer)
          e.SourceNode.GroupItems.Clear()
          e.SourceNode.Nodes.Clear()
          e.SourceNode.GroupItems.Add(item)
      End If
  End Sub

Please advise!

Thx
Gerhard

The tab toolbar items (Bold (B), italic (I), underlined (U), etc.) act like a Tab list (one can be selected), but when we navigate on it, the screen reader announces the role as a link, which is confusing.

Also, with the role link, the user is not getting enough information about which one is currently selected (visually with colour indication). The screen reader announces as 'Bold, link'.

The recording is attached in the zip file.

As you can see from the image, on mobile devices the date ends up breaking and making it impossible to view it completely.

This is my code:
<div class="col-xl-3 col-sm-6 col-md-6 col-xs-12 mb-2">
    <span class="EstiloLabelSimples">Data Vencimento:</span>
    <telerik:RadDatePicker RenderMode="Lightweight" ID="txtDataVencimentoCadastro" Width="100%" runat="server" />
</div>

I've tried using other RenderMode types, but none of them worked. Could someone help me achieve this responsiveness?

Hello,

I'm loading a RadTreeView from an xml file.  This has been working fine for a long time.

I've been tasked with adding a text link to another page to the right of specific nodes.

Since I'm using LoadContentFile of my RadTreeView, I'm not sure if there is a way to manipulate the nodes to add a link when loading data.

In my example below I need to find a way to add the Section links to the right of my nodes.  Can I add the section text and url as properties of a node in my xml?

Example layout

-Top

-2000s

-2021 Section 1

-2022  Section 1

-2023 Section 2

Thank you

Hi there

In order to get differing steps to show the levels on my stacked chart I can kind of do it using additional Y axis, but obviously this is showing them on separate lines.

Is it possible to manipulate the layout so that the lines are on top of each other so it looks like 1 line?

 

 

Thanks for your help
