[英]How to find a DropDownList in a GridView ItemTemplate without RowDataBound?
[英]Gridview Itemtemplate DropDownList Enabled
我希望僅在單擊Gridview
上的編輯鏈接后禁用DropDownList
並啟用它。 到目前為止,它顯示在編輯鏈接之前和之后禁用的DropDownList
。
代碼:
<asp:DropDownList ID="DropDownList1" runat="server" Height="30px" Width="190px" SelectedValue='<%# Eval("FAQGroup") %>' Enabled="false" >
<asp:ListItem Value="Most asked FAQ"></asp:ListItem>
<asp:ListItem Value="Normal FAQ"></asp:ListItem>
</asp:DropDownList>
aspx.cs
protected void gvFAQ_RowEditing(object sender, GridViewEditEventArgs e)
{
gvFAQ.Columns[3].Visible = true;
DropDownList DDL= (DropDownList)gvFAQ.Rows[e.NewEditIndex].FindControl("DropDownList1");
DDL.Enabled = true;
gvFAQ.EditIndex = e.NewEditIndex;
bind();
}
當您在RowEditing
事件處理程序的末尾調用bind
時,將清除並重新填充GridView,並在每行中創建一個新的DropDownList。 綁定數據后必須啟用控件,例如在RowDataBound
事件處理程序中:
protected void gvFAQ_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
DropDownList ddl = e.Row.FindControl("DropDownList1") as DropDownList;
ddl.Enabled = e.Row.RowIndex == gvFAQ.EditIndex;
}
}
