gridview中的dropdownlist从不可用到可用

Greg_han 2010-02-04 06:52:23

dropdwonlist 已经绑定好数据，载入页面时时enable=false；在点击“编辑”键后enable=true；但是依然是不可用
给出代码，请大家指点：
protected void GridView1_RowEditing1(object sender, GridViewEditEventArgs e)
{
GridView1.EditIndex = e.NewEditIndex;

GridViewRow gvr = GridView1.Rows[e.NewEditIndex];

downtest = (DropDownList)gvr.FindControl("DropDownList1");

downtest.Enabled = true;

}

<ItemTemplate>
<asp:DropDownList ID="ddlSort" runat="server" Width="98%">
</asp:DropDownList>
<asp:HiddenField ID="Hd_Sort" runat="server" Value=' <%# Eval("BalSort")%>' />
</ItemTemplate>
protected void gv_RowDataBound(object sender, GridViewRowEventArgs e)

if (e.Row.RowIndex != -1)
{ if (e.Row.RowState == DataControlRowState.Edit || e.Row.RowState == (DataControlRowState.Alternate | DataControlRowState.Edit))
{
((DropDownList)e.Row.FindControl("ddlSort")).SelectedValue = ((HiddenField)e.Row.FindControl("Hd_Sort")).Value;
}
}
}

protected void gv_RowEditing(object sender, GridViewEditEventArgs e)
{
gv.EditIndex = e.NewEditIndex;
string strSort = ((DropDownList)gv.Rows[e.NewEditIndex].FindControl("ddlSort")).SelectedValue.Trim();

gv.EditIndex = -1;
BindData();
}
