Telerik UI for ASP.NET AJAX in Jetbrains Rider

I don't see anyone talking about migrating from Visual Studio to Jetbrains Rider using Telerik.

I have a 20+ year project that's had Telerik being used for a long time. When opening the project in Jebrains Rider, there are a lot of referencing issues and a lot of it is messed up, mostly related to telerik. I mainly use the Telerik wizards for Reporting and for the Ajax UI version, which don't exist in Rider. I wanted to see if anyone has any tips or tricks, or if there is talk about creating plugins for telerik on Jetbrains Rider?

Hide a column programmatically

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!

How to trigger the server-side event of a RadToolBarButton inside a RadGrid using the Enter key

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

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

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

Accessibility issues related to Telerik RadEditor Classic Render Mode

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.

difficulty in RadDatePicker responsiveness

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?

Add link to the right of radtreeNode

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

Multiple Y axis on same line?

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
