我有一個帶下拉列表的Gridview是在GridView的OnRowDataBound事件中動態創建的,最初我設置了一個選定的值。DropDownList selectedindexchanged在GridView內的下拉式綁定期間不會觸發默認選定的項目
問題是,當我切換到不同的下拉下拉其工作正常,但當我更改爲默認選定的索引時,SelectedIndexChanged未被觸發。
請幫助我..
protected void OnRowDataBound(object sender, GridViewRowEventArgs e)
{
DropDownList DropDownList1 = new DropDownList();
DropDownList1.ID = "DropDownList1";
DropDownList1.SelectedIndexChanged += new EventHandler(DropDownList1_SelectedIndexChanged);
DropDownList1.EnableViewState = true;
DropDownList1.AutoPostBack = true;
DropDownList1.EnableViewState = true;
string sql1 = ".....";
DataTable dtDDL = new DataTable();
dtDDL = SQL.ReturnDataTable(sql1);
if (dtDDL.Rows.Count > 0)
{
DropDownList1.DataSource = dtDDL;
DropDownList1.DataTextField = "CODE";
DropDownList1.DataValueField = "CODE";
DropDownList1.DataBind();
DropDownList1.Font.Size = 8;
//DropDownList1.Items.Insert(0, new ListItem("0", "0"));
}
DropDownList1.SelectedValue = dtShift.Rows[0]["SHIFT_CODE"].ToString();
DropDownList1.ToolTip = dtShift.Rows[0]["ShiftTime"].ToString();
}
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
//not coming here for default index changed
}
