I have a Telerik RadGrid that has a DetailTable that can be expanded by the user. The DetailTable contains several selectable rows. The user is able to select some rows, then click a "Process Data" button that saves the row data in a Visual Basic code-behind file.
The RadGrid uses HierarchyLoadMode="conditional" to keep track of the DetailTable.
Two Problems-
1. When a user:
- expands the DetailTable,
- selects a row,
- collapses the DetailTable,
- clicks "Process Data,"
no data is saved because RadGrid.SelectedItems has 0 items. Even though the selected row is shown as selected in the UI.
However, if a user:
- selects a row,
- collapses the detail table,
- clicks "Process Data" + gets an error from the VB saying "No rows selected,"
- expands the detail table again,
- selects the row again,
- clicks "Process Data" again,
then the data will be saved because RadGrid.SelectedItems will include the row. Perhaps this is a bug?
In other words, a post back is needed to clear the detail table selections before RadGrid.SelectedItems actually includes items that have been selected in a collapsed HierarchyLoadMode="conditional" table.
2. Is there a way to have selections persist across pagination? Eg. If the user expands the DetailTable, selects a row, navigates to "page 2" of the detail table, then navigates back to "page 1," their selection is not saved.

I am creating a mobile website using radcomboboxes inside of update controls that are set to autopostback = true. All of the controls work except on the page's initial load the UI elements are enlarged and look more like buttons. They are still able to be selected and after the controls postback the elements still do not go back to a normal size. Only after a postback from another control do the UI elements shrink down to a normal size.
I have tested the radcombobox with checkboxes enabled outside of the update panel and this behavior does not change. I have a master page that contains jQuery files located in the header, and when I remove one of the js files, the problem disappears with the UI elements disappearing. Can anyone help me figure out what is preventing the UI elements from rendering properly?
On Load:
After postback:

Hi,
I'm getting the following exception multiple time throughout the application in error log. It's very difficult to identify the exact reason for exception occurrence as the application is vast to debug in depth. Also, I'm using Telerik Control as well as Telerik Reporting in multiple place in the application. The version of Telerik.Web.UI which I am currently using is 2023.1.323.45
EXCEPTION URL :
https://adba.roc-p.com:443/Telerik.Web.UI.WebResource.axd?type=rau
EXCEPTION MESSAGE :
System.ArgumentException: Illegal characters in path. at System.IO.Path.CheckInvalidPathChars(String path, Boolean checkAdditional) at System.IO.Path.GetExtension(String path) at Telerik.Web.UI.AsyncUploadHandler.ProcessUploadedFile() at Telerik.Web.UI.HandlerRouter.ProcessHandler(String handlerKey, HttpContext context) at Telerik.Web.UI.WebResource.ProcessRequest(HttpContext context) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStepImpl(IExecutionStep step) at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)
Can anyone please provide all the possible reason behind this exception along with its step to resolve. Any help will be highly appreciated!
NOTE :
I have already visited multiple forum in which it is mentioned that this issue occurs in the previous version of the Telerik.Web.UI. Please confirm whether the exception mentioned above still exist in the version of Telerik.Web.UI which I am currently using i.e. 2023.1.323.45. And If not then please provide the possible reason that we need to verify on our end.

Dear Telerik Team,
We have purchased Telerik UI for ASP.NET AJAX UI 2010.1519. Now we are facing vulnerable issues as it is using jQuery 1.4.2.
One of the Telerik doc tells that
When Telerik upgraded jQuery version to 3.3.1, it faces incompatibilities with the MS AJAX framework and its __doPostBack() method. Due to which, Telerik downgraded jQuery version Telerik UI for ASP.NET AJAX R1 2019 - present are using a modified jQuery version 1.12.4 that includes security vulnerability backport fixes.
Is there a fix to overcome this issue other than upgrading the Telerik version to 2019 or greater?

Hello, everyone. I'm a novice. I don't how to use the <GridImageColumn>, I have a request to display qualified photos from a remote computer.
For example, A textbox inputs 'abc',then I click the button of 'submit', the <GridImageColumn> or another control should find and display the 'abc.jpg' from the remote computer. The remote TargetFolder url just like '\\123.**.***.***\photo' and I hope it will be shown in <DetailTables> .
How should I edit the back-end code, so that I could get the pictures and also display it. I will post my code.
I'd really appreciate it if you could help me!

I've run into an issue using modal popups and controls on a page, and I've created a test scenario. What I'm trying to do is, when the user submits a form to save data to a database, the application first validates if everything is correct. If not, display a modal popup. This works find the first time I press "Save Data" in my test, but the 2nd time, any bound controls seem to lose their values. For example, the line -
Dim value As String = RadComboBox1.SelectedItem.Valuegives an 'Object reference not set to an instance of an object" error. Do I have to rebind every control on the page in the code-behind, or is there a better way to do this? Is this happening because I'm putting the RadWindowManager into the AjaxPanel? (I read a bit of documentation about it, but I couldn't clearly understand it).
EDIT: It also happens with another control (button) that does a postback. While rebinding does prevent the "Object Reference..." error, it loses its' selected value.

I allow the user to create in runtime, zones (my sections) and docks.
<asp:Repeater ID="repSections" runat="server" OnItemDataBound="repSections_ItemDataBound">
<ItemTemplate>
<asp:Panel ID="panelSection" runat="server" CssClass="container">
A RadDockZone(section) and it's RadDocks are injected here in runtime...
</asp:Panel>
</ItemTemplate>
</asp:Repeater>This repeater is populated from database and zones and it's docks injected in runtime, assigning the DockPositionChanged event to each of the created docks. Since I also inject in runtime, controls before and after each zone to manage it (Add, configure, move up/down) and I want them to postback using ajax, I'm configuring the ajax behavior in the ItemDataBound event of the Repeater:
protected void repSections_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
LinkButton linkbtAddNormalSection = e.Item.FindControl("linkbtAddNormalSection") as LinkButton;
linkbtAddNormalSection.CommandArgument = section.Id.ToString();
AjaxSetting ajaxSetting_linkbtAddNormalSection = new AjaxSetting();
ajaxSetting_linkbtAddNormalSection.AjaxControlID = linkbtAddNormalSection.UniqueID;
ajaxSetting_linkbtAddNormalSection.EventName = "Click";
ajaxSetting_linkbtAddNormalSection.UpdatedControls.AddRange(new AjaxUpdatedControlsCollection()
{
new AjaxUpdatedControl(repSections.UniqueID,""),
new AjaxUpdatedControl(panelNosections.UniqueID,""),
new AjaxUpdatedControl(radNotification.UniqueID, "")
});
ajaxManagerProxy.AjaxSettings.Add(ajaxSetting_linkbtAddNormalSection);
...
}Because of this, RadAjax places a RadAjaxPanel that includes all the created zones inside of the repeater causing the DockPositionChanged event to function in ajax mode. That's fine, and works great since avoids a regular postback each time a dock changes position.
The issue is that I need to show a RadNotification that is outside the repeater and consequently, outside that RadAjaxPanel and I can't show it from the DockPositionChanged event.
Any suggestion to overcome this?
Thank you!

Hello friends
Scenario:
On hovering the textbox an alert is triggered from clientscript.
The controls are placed inside a RadAjaxpanel.
Question:
Why does this setup only works on inital load?
If I submit the page, the clientscript does not work anymore.
Check my demo below.
kind regards

Hi,
I'm getting the following exception multiple time throughout the application in error log and the exception generates randomly while accessing any page in the application. It's pretty much difficult to identify the exact reason for exception occurrence as the application is vast to debug in depth. Also, I'm using Telerik Control as well as Telerik Reporting in multiple place in the application.
EXCEPTION URL :
EXCEPTION MESSAGE :
System.Web.HttpException (0x80004005): This is an invalid webresource request. at System.Web.Handlers.
Can anyone please provide all the possible reason behind this exception along with its step to resolve. Any help will be highly appreciated!
NOTE :
I have already visited multiple page in the forum those have similar issue but the solutions provided were specific to their script attached. Here, I'm not sure about the script which causes this exception randomly. I need to try all possible solution to get this issue resolve.
