After bind the DropdownList with datatable, I set the Text of the DropdownList in code, if the Text match one of element of the datatable, the SelectedValue should changed at the same time, in my case, it is not, I need to click the DropdownList to change the SelectedValue.
Anything I can do to sync the action that I get the right SelectedValue when I set Text match one of element of the datatable?

Hello,
I will have a short intro explaining why i need that (maybe you can find an alternative) you may skip and go to the code.
i have a scenario like the folowing example:
There is a List of objects, its properties are unknown at compile time (dynamic objects built from database), say these objects only have one property, called ExpireDate.
The user is presented a list of objects (with their expiredate and maybe other properties).
The user wants to change the expiredate for many of these objects to a specific date, the program will let the user select all the objects that need to be changed and edit the expiredate value in one shot.
After the user selected the objects to be changed, the UI will show the user a label and a control for each property:
in our case the control to handle the datetime will have a gray background and a null value if the selected objects have different ExpireDate, will have a white background when the selected objects have all the same ExpireDate value. This way the user knows, looking at a control, if it is blank because all objects have null value or it is blank cause some objects have different values.
Said that, after some work, this was the prototype code:
private void InitializeControlsBackground(){ foreach (var c in panel.Controls.OfType<Control>()) { if(EditorModel.GetProperties().OfType<MultiElement.MultiEditPropertyDescriptor>().Any(a=> a.Name == c.Name)) { Color bg = EditorModel.HasManyValues(c.Name) ? Color.Gray : Color.White; c.BackColor = bg; } }}the problem is that for some controls the background color changes, but for (example) raddatetimepicker the background color does not change, how can I change the background color for the raddatetimepicker?
Best regards

Hello,
I found a weird behavior that if the text of RadGalleryItem is longer than the image width, the margin/padding settings will lost.
To reproduce the issue, I changed the demo from:
https://www.telerik.com/forums/radgalleryelement-display-issue
RadGalleryItem blueItem1 = new RadGalleryItem("blue 1", Properties.Resources.group);this.radGalleryElement1.Items.Add(blueItem1);blueItem1.TextImageRelation = TextImageRelation.ImageAboveText;blueItem1.ImageAlignment = ContentAlignment.MiddleCenter;blueItem1.Margin = new Padding(1);RadGalleryItem blueItem2 = new RadGalleryItem("blue 222222222", Properties.Resources.group);this.radGalleryElement1.Items.Add(blueItem2);blueItem2.Margin = new Padding(1);blueItem2.TextImageRelation = TextImageRelation.ImageAboveText;blueItem2.ImageAlignment = ContentAlignment.MiddleCenter;RadGalleryItem blueItem3 = new RadGalleryItem("blue 3", Properties.Resources.group);this.radGalleryElement1.Items.Add(blueItem3);blueItem3.Margin = new Padding(1);blueItem3.TextImageRelation = TextImageRelation.ImageAboveText;blueItem3.ImageAlignment = ContentAlignment.MiddleCenter;RadGalleryItem blueItem4 = new RadGalleryItem("blue 4", Properties.Resources.group);this.radGalleryElement1.Items.Add(blueItem4);blueItem4.Margin = new Padding(1);blueItem4.TextImageRelation = TextImageRelation.ImageAboveText;blueItem4.ImageAlignment = ContentAlignment.MiddleCenter;
Please see the attach photo.
I've done 3 tests. First 2 tests work well as long as the text size is shorter than image width.
In the third one, I named on purpose blueItem2 with a long name "blue222222". In this case, I've lost all my margin settings.
