摘要:觸發GridView內控制項事件抓到當下被選的RowIndex
觸發GridView內控制項事件，DropDowList下拉選擇後，抓到將直傳入另一個TextBox，
Card_NO下拉選單連動Card_ID TextBox欄位
1. GridView + sqlDataSource
2.欄位轉成樣板，新增DropDownList作資料繫結，另一個欄位轉成樣板，新增TextBox
3.新增DropDownList2_SelectedIndexChanged
protected void DropDownList2_SelectedIndexChanged(object sender, EventArgs e)
{
//抓到控制項--因為這是控制項的事件sender就是DropDownList
DropDownList ddl2 = (DropDownList)sender;
GridViewRow gdrow = (GridViewRow)ddl2.NamingContainer;
TextBox tb5 = (TextBox)GridView1.Rows[gdrow.DataItemIndex].FindControl("TextBox5");
tb5.Text = "GA54" + ddl2.SelectedValue.ToString().Substring(2, 3);
}
