I have a ascx control that contains a popup radWindow which contains a datalist that is populated at the time the ascx is loaded on the page.  A button displays the radWindow with the preloaded values in a template, which contains an editable textbox on each row.  When the window is hidden, the textbox values should persist in the hidden window until the Save button on the main page is pressed saving the entire page, plus the values in the hidden radWindow.

When I load the page, and open the radWindow for the first time, the previously saved values are displayed in their respective textboxes.  If I then press OK to hide the window, then immediately reopen it, the values in the VISIBLE textbox are gone.  The values in the label control and the HIDDEN textbox are retained.

If when I open the window for the first time with the original values present, then change any one of the visible text boxes, then close and immediately reopen, all my values are retained, including the preloaded values plus any edits.  I can now open and close as many times as I want without changing any data values and not lose any values in the visible textboxes.

If I change the hidden textbox to visible, it also loses its values as in the above scenario.  If I change the visible textbox to hidden, it retains its values in all scenarios.  The label in the <itemtemplate> doesn't seem to be affected.  

If I navigate to the page, which prepopulates the datalist in the radWindow, and DO NOT open the window, then press save on the main page, I also lose the values in the Visible Textbox.

So, it appears that when a textbox is visible in the window, it does not persist its values, unless something has changed.  Not sure why it will show the values when the window opens for the first time and not show them on any subsequent open.  I have tweaked several settings on the radWindow control to no avail.  This is happening in multiple browsers (Chrome, IE, Edge), so not isolated to browser type.  I am curious what is triggered when a value is changed to suddenly persist the values in the VISIBLE text boxes, why the textboxes do not seem to have persisted values when they are visible, regardless if the window is opened or not.

I converted this from another third-party window control and it worked perfectly.  Since we are now using Telerik, it necessitated the change. The only changes I made to the sourcecode was the javascript function that opens the radWindow in the 'onclick' event and  the <telerik:windowmanager> tag, down the to the <ContentTemplate> wrapper tags.  Everything contained between the ContentTemplate tags is exactly the same, essentially reproducing the previous window controls behavior, with the exception of this issue.

Thoughts?!?

Button that opens the window: 

<input type="button" class="command_button" value="..." onclick="javascript: window.radopen(null, 'radPreWin');" />

Window:

Javascript function that hides the window when "OK" is pressed:

                oWindow.hide();

Right now, I am working in administration dashboard. Inside dashboard there is a left side menu which can be expanded or can be collapsed.Let me show you its code,

So as you could see there is some hard coded <ul> and <li>s out there and I need to replace it's content and those content will be populated from database.

Please run snippet to view content which will be shown in place of hard coded content as shown below,

Now, I wanna know If I could get desired output using RadPanelBar control?

Note:- What I am getting If I'm using RadPanelBar control..

Usually I use the MVC components, and understand that grid really well, but this is the first time using this version of the grid (UI for APS.NET AJAX), and am not familiar with it at all.  I have the option of AllowAutoUpdates marked as true, but when I click the edit link, the form that displays for editing really looks bad.  The form field captions all seem to be aligned to the left, but the form fields are way over to the right.  How can I make this look better?

Hi There,

I have come back to a system I coded 2 years ago. The code worked fine when I last worked on the web app but now I am getting the attached errors.

Does anyone have any ideas why I'm getting these errors.

Thanks for your help.

Best Regards,

Steve.

InitialFileInputsCount="1" MultipleFileSelection="Automatic" OnValidatingFile="RadAsyncUpload_ValidatingFile" />

I am getting this script error in Chrome 67.0.3396.99 when I click a button to edit a column of RadGrid using a custom form template with EditFormType="WebUserControl".  None of the RadNumericTextBox controls seem to work because of the error. 

I have EditMode=PopUp and RenderMode="Auto" which works fine in standard desktop size/mode where I get a popup.  However, I get this error simulating mobile devices when an inline form is displayed instead of a popup:

The issue appears to be with RadListBox.  I'm not using any RadListBox so it must be a control rendered automatically by Telerik software.

I tried updating to the latest Telerik controls (2018.2.710).  I tried changing my popup controls from ClientIdMode=Static to ClientIdMode=Auto.  I tried adding my popup controls to the list of <UpdatedControls> in <telerik:AjaxSetting AjaxControlID="RadGrid1">.  I tried disabling compression in both page and popup.  I followed links to several forum posts but have been unable to resolve the issue.  What would you suggest?  Thanks!

Here is the content of my popup (AdjustInventoryQuantity.ascx):

Here is the content of my page:

Page Script:

Hello, I'm new in telerik teleport designer and i need "Radgrid Header Context Menu Filter option for choosing columns displayed", but i don't know, where i can find it menu in telerik. can you help me? I can't find "EnableHeaderContextMenu" also:(

Please, help me(

I'm using "AllowCustomSorting" to prevent the RadGrid from sorting the values (they are already sorted) and let it just show the sort direction.

This works fine for "normal" columns.

But if such a column is grouped, the RadGrid ignores this setting and sorts by itself.

In my case it's a column with DateTime values (already formatted as strings) - they are already correctly sorted. But if I group this column, the RadGrid sorts the values itself, and especially for DateTime values as strings, this doesn't work correctly.

How can I prevent the RadGrid from sorting grouped columns and just use them as they are? I'm on the current version (2018.1) of Telerik ASP.NET Ajax.

Thanks!

Hi,

My issue and code here:
I have a telerik RadNumeric Text Box and a button.  When i enter 6 digit number in the text box, it should auto tab to button.
I am using "OnKeyUp" to achieve this. The first time i type in the 6 digits into the text box, it auto tabs to the button. After that, if i go back to the text box to enter a new number, after entering a single digit, it auto tabs out. It does not wait till i enter 6 digits to tab out.
I can't figure out why it is tabbing out after entering a single digit. 
NOTE: When i load the page the first time, it works good. It tabs out after entering 6 digits. Every subsequent attempt  to enter a number in that text box, it tabs out after single digit.(No new page load involved). Why is it tabbing out after entering single digit
