Why don't you reply?

Tired of repeating the same answer to your customers over and over again?

I am not American. So I am not good at reading English. I am currently writing the article after translating it into English using Google Translate. Aren't we supposed to help people with disabilities in English? Is telerik annoyed with answering customers?

I hope my question is answered.

I am waiting for your reply for several days.
Telerik does not respond to customers.
Inconvenient to use Telerik.

Hello.

I need help.

I need the coordinates of Column + Row of the selected cell in Radgrid.
Is the syntax of the source I attached correct?

please reply.

keep waiting for your reply

I want to communicate with client side and server side.


In Server Side(ASP.NET), 
<ClientSettings>
    <Selecting CellSelectionMode="MultiCell" />

In JavaScript,
function cellSelected(sender, args)

sender.get_masterTableView().fireCommand("cellSelected",    ????????????? );

I have a RadHtmlChart in an ASP.NET application to show a pie chart that has stopped working for some reason, it just shows a blank space instead of where the chart is supposed to be. I think that it may have been a result of updating from Telerik 2019 to 2021, but I don't know for sure.

I see an error in the console log like this that I think may be related:

I need more specifics about how to cancel a tab switch when using the RadTabStrip. The information I have found on the Telerik help forums makes a lot of assumptions about knowledge of the programmer, and (although I have lots of programming experience) I'm fairly new at Telerik and asp programming in general. 

I'm using the Telerik RadTabStrip and I need to cancel on the client side the switching from one tab to another. The RadTabStrip is on a general management page that references the other tabs (asp pages), one for each tab.

In the first tab asp page, I have a hidden control that contains an indicator if the page is dirty. 

In the management page, containing the RadTabStip, I have a java script function for the OnClientTabSelecting. From the management page java script function for OnClientTabSelecting I need to A) check if I'm leaving the page which may be dirty and B) if that is the page i'm leaving then I need to check the dirty flag. If both A and B are true, then C) I need to prompt the user, warning them that the page is dirty and confirming that they do want to leave. If they do not, then I want to cancel the tab switch. 

I understand how to to C) above, but could you please provide some example code of both A) and B) above? If the examples exist elsewhere, then a link to those examples would be very helpful.

Thank you!

Hi,

I am binding data to RadMultiSelect control through web service method.

when I am trying to filter data (typing on RadMultiselect control) it calls web service method twice.

Issue is, either it holds the filter value in first time hit, second time hit filter value get cleared. 

How can I prevent web service multiple times hit.

I have inserted the code for your reference.

Hi Telerik's friends

I have a RadComboBox that I load with a DataTable. This is my code:

    Private Sub LoadAgente()
        Dim rcbElemento As New RadComboBoxItem

        Me.rcbAgente.DataSource = GetNombreAgente() ' Get DataTable
        Me.rcbAgente.DataValueField = "CodigoPersona"
        Me.rcbAgente.DataTextField = "NombreCompleto"
        Me.rcbAgente.DataBind()

        rcbElemento.Value = "0"
        rcbElemento.Text = "Seleccione un agente"
        Me.rcbAgente.Items.Insert(0, rcbElemento)
        rcbElemento = Nothing

        Me.rcbAgente.ClearSelection()
        Me.rcbAgente.SelectedValue = "0"
    End Sub

But this don't work.

I need your help. please.

Thanks

I have hierarchal data with thousands of nodes.  I am using a RadTreeView control with "Load On Demand" mode, with Expand mode set to "ServerSideCallback".  I set up the handler. It creates the child nodes, grabs about 10 custom fields and adds them to the "Attributes" collection, and adds the nodes to e.Node.Nodes collection.  All of this is working great, but I want to display values from the Attributes collection.

How do I access those attributes from the NodeTemplate? 

The node template seems to work, but it is not showing the fields. I assume this is because I am just adding the nodes and do not call "DataBind"?

Thanks.

I will convert the attached file to RadListBox.

You need to add 2 Labels to the RadListBox in the attached file.

Conversion condition requires adding 2 Labels to RadListBox.

Attached files(WebApplication14.zip) must be converted like attached files(RadListBox.png).

Please Help me.

Question-1) ItemTemplate of RadListBox, By applying multi-label, Is it possible to implement multi-column of ListBox?

Question-2) If Question-1 is possible, As in the attached file, After creating one more RadListBox, Is it possible to move data between listboxes?

Question-3) If Question-2 is possible, like the source below,Listbox.Item.Add(item),  Listbox.Item.Insert(index),  Listbox.SelectedItemindex, Listbox.Selected.Items.Count   

Can you code using functions?
