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 have an old ASPX Web Forms application.  I am trying to pick the right update to replace the old Telerik UI for ASP.NET AJAX version 2014.2.724.40.  The application is build using .Net Framework 4.7.2.

I have downloaded TelerikUIForAspNetAjaxSetup, but all the options seem to be for the more modern .Net Core.  Where can I find the per-core library?

thank you

Philip

Hi,

My situation: I have a Radgrid with TooltipManager setup which works fine.

Now I have to place another RadGrid in the Tooltip which has an update button per row.
How would one configure so, that the Tooltip's RadGrid is updated in the Tooltip.
Please see attached screenshot...

Thanks for any pointers.

Marc

I inherited a .NET website using RadAjax.Net2.dlls. Currently only supported in IE compatibility mode from my understanding.  I would like to upgrade to a version that works in current browsers.  The website is using .NET 2.0 but we are upgrading the framework to 2.8 if possible.   I appreciate any recommendations on upgrade path.

Hello,

I made an update to the newest Telerik.Web.UI Version 2023.3.1010.45 and now I cannot collapse my RadGrid-Items anymore after expanding.  Instead I can see a statusbar which is loading infinite long on the left side when the ViewState is enabled in the Sitefinity Backend. When I disable the ViewState I have the same problem, just without statusbar. There is a screenshot of the grid and my HTML-Code in the attachment. Could anybody help me?

Regards

I'm using AJAX RadImageEditor in an aspx page:

                <telerik:RadImageEditor ID="RadImageEditorFront" CssClass="ImageCtrl"  runat="server" Skin="Telerik" Width="545px" Height="300px" RenderMode ="Lightweight" StatusBarMode="Hidden" style="top: 0px; left: 0px">
                    <Tools>
                        <telerik:ImageEditorToolGroup>
                            <telerik:ImageEditorTool Text="ZoomIn" CommandName="ZoomIn" /> 
                            <telerik:ImageEditorTool Text="ZoomOut" CommandName="ZoomOut" />
                            <telerik:ImageEditorTool Text="ZoomOut" CommandName="Zoom" />
                            <telerik:ImageEditorTool Text="Rotate Right" CommandName="RotateRight" /> 
                            <telerik:ImageEditorTool Text="Rotate Left" CommandName="RotateLeft" />
                            <telerik:ImageEditorTool Text="Flip Vertical" CommandName="FlipVertical" />
                        </telerik:ImageEditorToolGroup>                

                    </Tools>
                </telerik:RadImageEditor>

 

I need to change the percentage that the AJAX RadImageEditor zooms in or out on the loaded image when I call the client side methods zoomIn() or zoomOut().

When I use the client side methods zoomIn() or zoomOut(), the image is zoomed in at 50%.

var radImageEditor = $telerik.findControl(document.documentElement, $(this).attr("id"));

radImageEditor.zoomIn(); or radImageEditor.zoomOut();

(note: jQuery code above)

I have tried zoomImage(zoomLevel, shouldUpdateUI), but that did not appear to be the solution (the image became a small dot on the screen).

How can I change the zoom in and zoom out percentage (scale) to 10% for the AJAX RadImageEditor - or asked another way - how can I get the image to scale 10% (instead of 50%) each time I call zoomIn() or zoomOut (or another zooming method)?

I am using RadScheduler with TimeLineView Only, GroupBy Resource with GroupDirection set Vertical.

I set the object height to 585px, but when rendered, it only shows 360px, as you can see in the image.

What can I do to work around this situation without changing the rowHeight property?

I am using server-side binding but if I change to client-side binding, can I solve this problem modifying Client Rendering?
