Binding a ComboBox to data displayed in a data grid

Lost on implementing a combobox whos value will dictate what data is displayed in a data grid. So when a new value is selected from the datagrid, without refreshing the page and using the radajaxmanager to read from a database and refresh the data in the data grid. Is that possible and what other components will be needed? So far I am using but still not sure how to use the RadAjaxManager, RabComboBox, RadSplitter, RapPane, and a RadGrid.

Struggling with this online ListView demo!

First of all I am not too much experienced with Telerik controls and I confess that it puzzles me but I am not going to give up!

So, I am not being able to reproduce the demo at https://demos.telerik.com/aspnet-ajax/listview/examples/overview/defaultvb.aspx?show-source=true.

I simplified the code to use it with my own data (code below) and I am experiencing two problems:

Instead to appear in two columns it only appear as a single list; and
It 's not skinning as it should.

To see my test in action please check http://aspdotnetstorefront.pamsauto.com/tests/ListViewTest.aspx

And this is my code:

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="ListViewTest.aspx.vb" Inherits="custom_scripts_iPMP_ListViewTest" %>

<%@ Register TagPrefix="qsf" Namespace="Telerik.QuickStart" %>

<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>

I would appreciate if someone could give some help. Thanks!

Error 500 after upgrade

Hello,

I have a AsyncUploadHandler that works fine in an older version 2019.1.215 but as soon as I upgrade to newer version e.g. 2021.1.119 I start getting error 500

I doubt that my handler is still referencing the old version but can't find where it happens and change it eventually.

Any ideas?

Thank you very much

Implementing CSS class for the last child node in the treeview control

Hi,

We are dynamically generating RAD Treeview control with data. We need to have a hover=hand and other stylesheets effect on the last node of all the parent nodes. Any code to traverse through all nodes and applying CSS will be helpful.

Node1-->NO style sheet
    Node2-->NO style sheet
        Node3-->Need to apply style sheet
        Node4-->Need to apply style sheet

Node11-->NO style sheet
    Node22-->Need to apply style sheet

+Node22
+Node44

regards,

[Solved] RadMultiSelect doesn't seem to work with RequiredFieldValidator

I just get the following stacktrace:

An unknown error has occurred.Control '[ControlNamePlaceholder]' referenced by the ControlToValidate property of 'reqControlNamePlaceholder' cannot be validated

Is this by design, or is this control different than all the rest that do work with a requiredfieldvalidator?

[Solved] How do you programmatically clear selected values?

I thought I could do it with "[control_name].items.clear()" but that doesn't seem to work either.

Unable to find an embedded skin

I don't know if this is the proper place for this but I am having issues with the use of skins and didn't know where to post.

There is an article here that says that we have a sort of built-in skins available.

I would like to know what do I need to do to get access to this because any time I try to Skin="skin_name" a control I get a page error just like this:

Telerik.Web.UI.RadListView with ID='RadListView1' was unable to find an embedded skin with the name 'Silk'. Please, make sure that the skin name is spelled correctly and that you have added a reference to the Telerik.Web.UI.Skins.dll assembly in your project. If you want to use a custom skin, set EnableEmbeddedSkins=false.

Any idea?
