EditFormSettings EditFormType="Template" with inner user control whose components are all null

Hello,
I am using a RadGrid with EditFormSettings EditFormType="Template".
I would like to add inside the <FormTemplate> a user control that resides in another library that I had created as an embedded resource library as described here: https://www.codeproject.com/kb/user-controls/embeddedusercontrol.aspx.
The problem I'm facing is that when trying to display the edit form, in Page_Load event inside my user control, all inner components (textboxes, radwindows, etc.) are null.
What am I doing wrong?

Another alternative I had thought about would be to wrap my formtemplate in a usercontrol that I would like to store in my controls library. In this case,
what would be the UserControlPath? I have found an example with applications root reference (UserControlPath="~/WebUserControl.ascx"), but I was not able to point it to a different assembly.
Is there any way of creating the user control in code behind and set it to the grid edit form?

Any help would be appreciated. Thanks in advance.

RadGrid Batch Update NewValues Question

Hi there.

We're working on a project with RadGrid controls that are doing batch updates.

The event that we have attached to the update event (RadGridActionGroup_UpdateCommand) has 2 parameters where we're sending to the db for updates.

protected void RadGridActionGroup_UpdateCommand(object sender, GridCommandEventArgs e)

{

try

{

Hashtable newValues = (e.CommandArgument as GridBatchEditingEventArgument).NewValues;

performActionGroupModelUpdate(newValues);

}

catch (Exception ex)

{

ConfigurationController.AddMessage(ex.Message.ToString());

}

When a user updates only one field in a row of say, five values, I would expect that only changed values would be sent to this event method, however even though only one field was changed, all of the values (updated as well as non-updated) are sent to to this event.

Is this by design or am I doing something wrong?

Thanks in advance

RadSearchBox searchText length on DataSourceSelect is not correct

Hello,

I am using a RadSearchBox with MinFilterLength="3". I am interested in filtering my search in OnDataSourceSelect, but even when I type 4 characters, this method:
protected void RadSearchBox1_DataSourceSelect(object sender, Telerik.Web.UI.SearchBoxDataSourceSelectEventArgs e)
{
string searchText = e.FilterString;

}
e.FilterString.Length returns 3 and RadSearchBox1.Text.Length is also 3 inside the method RadSearchBox1_DataSourceSelect

This is not narrowing enough my result set and I do not want to set MinFilterLength="4" because I have to allow also searchs by 3 characters.
Any suggestion will be welcome. Thanks in advance.

Chrome error on Rad Scheduler appointment resize or move event when browser window is scrolled.

We have been using the RadScheduler in our system for a couple of years. About 1 month ago our customers started reporting a bug when editing appointments. In Chrome when the a scheduler appointment is resized or moved it works the first time, but subsequent changes have no effect, as if the postback isn’t happening.

Occasionally we also see this js error popping up in the browser console.
Uncaught TypeError: Cannot read property ‘viewPartIndex’ of null
At a.DayModel._getTimeFromIndex ….

After 3 days of investigation we’ve still not managed to resolve the issue, however, interestingly we've found that removing <!DocType html> to put the browser in 'quirks mode' for Chrome improves the bug but obviously this isn’t a solution!

We’ve tried 3 version of the Telerik.Web.UI (2015.2.623.45, 2015.3.1111.45, and 2017.3.913.45). The error appears in all.

It seems the issue has been raised lots of times previously but as far as I can tell Telerik have never resolved it?

Any advice would be greatly appreciated as it's affecting a large number of our customers.

We’ve reproduced the error in a very basic demo (see below) to discount anything in our code.
