i have a radgrid that i have a buttoncolumn applied. the buttons work fine but i was curious if it is possible to only enable the button for the selected row?
If no rows are selected all buttons are shown, but disabled. when i click on a row the button on that row becomes enabled, and if i select another row, the button on the row i was on becomes disabled and the new row button is enabled?
i hope i am clear on this, im still very new to the telerik controls and c#. i have not been able to find anything on this matter.
Thanks!

Hi,
We are trying to upgrade the browser from IE9 to IE11.
We are using VS 2012 and Telerik controls for ASP.NET AJAX version 2013.3.1114.45.
We are configuring the radgrid programmatically in .cs page and already set the MasterView width to 100%.​
The grid is not displayed properly in IE 11 compatibility mode. But displayed correctly in IE 11 normal mode.
Any idea how to resolve the mentioned issue ?
Thanks
Bhanu.

Hi Folks,
I had previously set up my RadRotator using a DataSource with a bound ImageURL to server path to image files. This was working fine up until last night when our Windows update went live. I presume it's done something with IE11 (our default browser) as the images for the rotator are now not showing.
The rotator itself loads; the buttons are visible. Just no images.
When loading the webpage under Chrome, Firefox or Edge, it still works correctly.
Does anyone know specifically what has happened to stop the images loading, and what I'll need to do to fix this? I'm guessing it might have something to do with security around either the database or loading images directly from a server path.

Attempting to use an XmlDataSource to populate the values in a dropdown list control in a GridTemplateColumn edit and insert templates.
Searched over:
1 - using ASP datasources: https://docs.telerik.com/devtools/aspnet-ajax/controls/combobox/data-binding/binding-to-asp-datasource-components
2 - using inline XML in an XmlDataSource: http://www.java2s.com/Code/ASP/XML/UsingInlineXMLDatainanXmlDataSourceControl.htm
3 - fixing the 'GridInsertionObject does not contain a property named 'X' ' error: https://weblogs.asp.net/kencox/fixing-the-telerik-webcontrols-gridinsertionobject-does-not-contain-a-property-error
4- Populating a dropdownlist in a datagrid template column: https://docs.telerik.com/devtools/aspnet-ajax/controls/grid/how-to/Common/radcombobox-in-radgrid
* Yes, the links above reference the combobox control, presumably the dropdown list functions the same way.
Goal: Populate a DropDown list using an XmlDataSource and inline XML
Problem: it does not work.
Looking for the proper format of the inline XML to get this to work.
Links 1 and 4 say that the XML file has to be formatted as <items><item>, but this causes an error when inline stating that 'items' is invalid'
Links 2 say to use <Data><items><item>, which doesn't throw an error but doesn't load
Using the method from Link 3 to set the default values, I avoid the GridInsertObject error, but the defaulted value is not bound.
<telerik:GridTemplateColumn HeaderText="Wpn Qual" DefaultInsertValue="M"> <ItemTemplate><%#DataBinder.Eval(Container.DataItem,"WPN_QUAL_BADGE") %></ItemTemplate> <EditItemTemplate> <telerik:RadDropDownList runat="server" ID="ddlWpnQual" DataTextField="Text" DataValueField="Value" DataSourceID="xmlWpnQual" SelectedValue='<%#Bind("WPN_QUAL_BADGE") %>' ></telerik:RadDropDownList> </EditItemTemplate> <InsertItemTemplate> <telerik:RadDropDownList runat="server" ID="ddlWpnQual" DataTextField="Text" DataValueField="Value" DataSourceID="xmlWpnQual" SelectedValue='<%#Bind("WPN_QUAL_BADGE") %>' ></telerik:RadDropDownList> </InsertItemTemplate></telerik:GridTemplateColumn>
<asp:XmlDataSource ID="xmlWpnQual" runat="server" XPath="Data/Items" > <Data> <Items> <Item Text="-- Select --" Value="" /> <Item Text="Marksman" Value="M" /> <Item Text="SharpShooter" Value="S" /> <Item Text="Expert" Value="E" /> </Items> </Data></asp:XmlDataSource>
And yes, I can manually create the items via markup in each instance of the dropdownlist... I would prefer to use a scalable approach in this specific instance.

Hi
For my dropdownlist, everything works fine except the arrow is not showing up. png files are there in ...Styles/Default folder. Is there another file that would be missing in my project, something like ...kendo.all.min.js or whatever...

Windows 7 Enterprise - IE 11 (Version 11.0.9600.19236)
VS 2012 - .NET Framework 3.5
Telerik UI For ASP.NET AJAX 2016.2.607.305
We've been using the RadRadialGauge control in our intranet web application for years since around 2016 with no issues. Just recently (not sure exactly when) our users started noticing that the control was no longer displaying, just completely blank (see attachment 3-RadRadialGauge_Missing.jpg). After some analyzing & testing I've determined it doesn't seem to be a licensing or server-side issue.
To come to this conclusion I decided to try the RadLabel control which is just textual & has no graphic rendering like RadRadialGauge (see attachment 1-RadLabel.jpg). It appears fine since it's only displaying text.
Next I tried RadDatePicker which has a combination of text & graphic rendering (see attachment 2-RadDatePicker.jpg). It resulted in sort of a hybrid display where the date input box is there, but instead of showing the calendar icon it just has the mouse hover text.
It should be noted throughout this process I also tried downloading the latest version of these controls (2019.1.115.35) but still experienced the same behavior. I'm theorizing these problems are due to a Windows or more likely IE update which we might have recently received. All software updates like this are managed at the Enterprise level & pushed to all users in our company. I've tried searching the forums & I see here & there somewhat similar rendering issues posted, but nothing so far which has resolved my particular issue.
Any help would be greatly appreciated!

Hi,
I have a split button and RadContextMenu, however for the life of me cannot get the MPE to fire from the Context items and its driving me up the wall. Can anyone please help point me in the right direction.

and my code behind.
using System;using Telerik.Web.UI;public partial class Default : System.Web.UI.Page{ protected void Page_Load(object sender, EventArgs e) { } protected void POActionsMenu_ItemClick(object sender, RadMenuEventArgs e) { RadContextMenu btn = (RadContextMenu)(sender); string value = btn.SelectedValue; switch (value) { //View PO case "1": break; //Send me a copy case "2": break; //Export CSV case "3": break; //Change status to printed case "4": // btnConfirmYes.CommandArgument = "Change to Printed"; mpeConfirm.Show(); //changeStatusToP(); break; //Delete po case "5": // btnConfirmYes.CommandArgument = "Delete PO"; mpeConfirm.Show(); // deletePO(); break; } }}
Thanks in advance, its driving me crazy as it hits the mpeConfirm.show() event but never shows. (CSS not included)
