Problems with the selected value of DropDownList in the GridView

Use the value attribute on the page to fetch DropDownList by JS
DropDownList selected values in the background with the Text property

In the background CS code

First find the control:

DropDownList droptemp = this. Gridview1.rows[i]. FindControl ("DropDownList1") as DropDownList;

And then get the selected value:

DropTemp.SelectedItem.Text

Here's what you need to notice:

In addition to the Text property to get the selected value, all other properties are obtained by default, which is the value of the first item.

such as: DropTemp.SelectedItem.Value, Droptemp.selectedvalue, and Droptemp.selectedindex are all the display values of the first item taken.
