Background:
(Please refer attached for sample project)
private void radGridView1_EditorRequired(object sender, EditorRequiredEventArgs e)
{
if (this.radGridView1.CurrentColumn.Name == "Value" && this.radGridView1.CurrentRow.Cells[2].Value.ToString() == "DropDown")
{
RadDropDownListEditor editor = new RadDropDownListEditor();
RadDropDownListEditorElement element = editor.EditorElement as RadDropDownListEditorElement;
element.DropDownStyle = RadDropDownStyle.DropDownList;
element.AutoSizeItems = true;
var selection = this.radGridView1.CurrentRow.Cells[3].Value.ToString().Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries).ToList();
element.DataSource = selection;
e.Editor = editor;
}
else if (this.radGridView1.CurrentColumn.Name == "Value" && this.radGridView1.CurrentRow.Cells[2].Value.ToString() == "Date")
{
RadDateTimeEditor editor = new RadDateTimeEditor();
editor.CustomFormat = "dd-MMM-yyyy";
e.Editor = editor;
}
}
Question:
I have tried to set the CustomFormat but the format remains as shown in the screenshot above.
RadDateTimeEditor editor = new RadDateTimeEditor();
editor.CustomFormat = "dd-MMM-yyyy";
e.Editor = editor;
I'm trying to drag and drop RadCallout to an existing Form Designer, and while I don't get any errors and it appears that it drags and drops, the control doesn't remain on the form and does not appear in the Components Tray either. I do not have a problem adding other Rad controls, but Callout doesn't seem to work. Will it only work with a Rad Form? Or is there a prerequisite I should know about? Do I need to install something so that the Designer can properly display it?
I'm using Visual Studio Professional 2022 version 17.5.5 with Telerik UI for WinForms Extension 2023.1.313.33.
Thanks in advance!

Hi,

When I load data into my sheets, where there are columns which have a lot of data (long descriptions of things) and I use 'autoFitWidth to make things look sensible, I end up with some very wide columns, as expected.
Where a column is wider than the viewable area, left and right scroll often don't do anything: the sheet still shows one column. It seems to want to show all of a column, so after a while, it jumps to the next wide column.
(zipped video below)
This is strange behaviour, and also means that my users can not figure out how to re-size one of these wide columns, and then use word wrapping to make it easier to read.
Have I done something bad to my data to make it do this ? Or is there a setting somewhere to make the scrolling smooth?
Thanks
Hi guys,
I have been searching for a correct answer for that, but without success. It looks like work in C# but not in VB.
I want to implement a TAB between the rows in this sample project. Any idea what is missed?

There are hundreds of installed examples but they're all without projects. Putting them in a project results in many build errors.
What is the procedure for running the examples?

I'm using the built-in 'Fluent' Theme, and one bit I don't like is that by default the color of the text in a text box (and same for most other controls) is a mid-grey. This only turns to black when the mouse hovers over it.
Is there a simple way to change this behaviour? To make it black all the time? It's making it hard to take video of my application being used, because the text is quite pale.
Oh, and PLEASE don't tell me that 'I just need to edit the Theme' - I don't make changes to themes very often, and each time I do, I have to re-discover how powerful - and complicated - it is. :-)

Hi,
I have used RadListControl.ScrollToItem to bring a searched for item into view,thi sbrings it into view but either at top or bottom of the list. Is it possible to somehow center the selected item in the middle of the view so that I can obtain context based on surrounding items ?
Many thanks
Toby
