Question

GridView1_RowDataBound事件中如何获得gridview当前行的ID

前台 +
<asp:TemplateField HeaderText="完成状态">
<HeaderStyle HorizontalAlign="Left"></HeaderStyle>
<ItemStyle CssClass="String" Width="10%" />
<edititemtemplate>
<asp:DropDownList ID="PJStateDDList" runat="server" Width="90%">
</asp:DropDownList>
</edititemtemplate>
<itemtemplate>
<asp:Label id="RoleDisp" runat="server" text='<%# ChangeInttoString((int)Eval("PJState"))%>'></asp:Label>
</itemtemplate>
</asp:TemplateField>

后台
protected void TotalGridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
DropDownList PJStateList1 = (DropDownList)e.Row.FindControl("PJStateDDList");
if (e.Row.RowType == DataControlRowType.DataRow)
{
DropDownList PJStateList = new DropDownList();
PJStateList = e.Row.FindControl("PJStateDDList") as DropDownList;
if (PJStateList != null)
{
.......
}
}
总是提示 PJStateList‘NULl
可以给个简单的例子吗？谢谢

Answer 1

protected void TotalGridView_RowDataBound(object sender, GridViewRowEventArgs e)
{

if (e.Row.RowType == DataControlRowType.DataRow)
{
DropDownList PJStateList1 = ((DropDownList)e.Row.FindControl.("PJStateDDList"));
if (PJStateList1 != null)
{
.......
}
}
应该是这样子，你试试看后台代码，，前几天写了跟你差不多的。。只不过我是获取Button控件

追问

是不是GRIDVIEW属性设置有问题，否则按照你写的我修改了，PJStateList1还是null

Answer 2

说明你为查询到数据，你看看的数据库是否有数据或者看看你的代码是否绑定好了

追问

我没有绑定数据库数据，只是 if (PJStateList != null)时 PJStateList.Items.Add(new ListItem("完成", "0")); ，求指导，谢谢
