Hi everyone,
I used the below code to show the Dropdown Popup everytime user hits Tab to go to that control. However, now the pop up will disappear if user clicks the little button on the right side of the DropDown control (normal way to show popup), this issue only happens on the first time when the control gets focused. Do you know how to fix this?
Thank you.

Hi Arman,
Thank you for contacting us.
Instead of using the Show method you can programmatically perform click to the drop down list button. This can be done in the GotFocus event of the control for example:
Let me know if you have additional questions.

Hi Dimitar,
I changed the code as your suggestion. The problem is still there: when you click on the ArrowButton manually, the popup will disappear on the first time the control gets focus. You can test that by moving focus to another control, and then click back to the drop down list ArrowButton.

Hello Arman,
Thank you for writing back.
Apparently I have missed this exact case. Nevertheless you can avoid this behavior by changing the code like this:
In this case we will show the drop down manually when the focus is gained, and the button is not clicked.
Do not hesitate to contact us if you have other questions.

Hello, Ras Ran,
You can find below the C# code snippet:
private void radDropDownList1_GotFocus(object sender, EventArgs e)
{
RadElement element = this.radDropDownList1.DropDownListElement.ElementTree.GetElementAtPoint(this.radDropDownList1.DropDownListElement.PointFromScreen(Control.MousePosition));
if (!(element is RadDropDownListArrowButtonElement) && MouseButtons != System.Windows.Forms.MouseButtons.Left)
{
this.radDropDownList1.DropDownListElement.ArrowButton.PerformClick();
}
}Feel free to use our free online converter for C# to VB.NET conversion and vice versa: https://converter.telerik.com/
It is quite useful for such cases.
