在Gridview C#中将组合框转换为文本框

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        // 找到需要转换的列的索引
        int columnIndex = 2; // 假设需要转换的列是第三列

        // 找到组合框和文本框控件
        DropDownList ddl = (DropDownList)e.Row.Cells[columnIndex].FindControl("DropDownList1");
        TextBox txt = (TextBox)e.Row.Cells[columnIndex].FindControl("TextBox1");

        // 将组合框的值赋给文本框
        txt.Text = ddl.SelectedItem.Text;

        // 隐藏组合框
        ddl.Visible = false;
    }
}
