This is how my combo box set up in aspx page

I wanted to select the value from combo box using vb.net it select the value but the selected text will always “Select  a Value” which is default value.

This is how I am change the selected value inside the code

Me.cmbTechnicalServicePerson.SelectedValue = DRProjectDetailsinfo.Item("TechnicalServicePerson")

Or Me.cmbTechnicalServicePerson.SelectedValue = 12551

But it is not selecting the text any idea

Thanks
