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);

}
