Unlike a TextBox, the Combobox.text property does not get the text in the text box, which is exactly the same as Combobox.selectedvalue, and can only get value from the Drop-down list. If you want to get the text in the ComboBox text box, you can only read it through the Combobox.controls property.
Copy Code code as follows:
((TextBox) ((Table) comboboxcomponent.controls[0]). Rows[0]. Cells[0]. Controls[0]). Text
This is the text you entered in ComboBox.
