推荐答案

转到GridView的RowDataBound事件，找到EditItemTemplate中的DropDownList并绑定数据并在那里设置所选值。

试试这个：

Go to your RowDataBound Event of GridView, Find the DropDownList which is in EditItemTemplate and bind the data and set the selected value there.
Try this:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        DropDownList ddlCountry = e.Row.FindControl("ddlCountry") as DropDownList;

        if (ddlCountry != null){
            // Write your code to bind dropdownlist and set it's selected value here.
        }
    }
}

或

请参阅此示例在GridView RowEditing命令中绑定DropDownList [ ^ ]。
