Question

我有一个嵌套在转发器中的gridview，我想在行数据绑定上或通过

更改gridview列的标题文本

 <HeaderTemplate>
<asp:Label runat="server" ID="lblMode" Text='<%# Eval("IsValidForPromoCode")%>'>
</asp:Label></HeaderTemplate>

无论哪个方便。

.aspx page

<asp:Repeater ID="repRequest" runat="server" OnItemDataBound="repRequest_ItemDataBound">
                                <ItemTemplate>

                                    </table>

                            </asp:Repeater>

背后的代码

 protected void gvOption_RowDataBound(object sender, GridViewRowEventArgs e)
{
    try
    {
        GridView gvOption = (GridView)sender;
        if (e.Row.RowType == DataControlRowType.DataRow)
        {               
            gvOption.Columns[1].HeaderText = "Last Name";               
        }
        if (e.Row.RowType == DataControlRowType.Header)
        {
            gvOption.Columns[2].HeaderText = "Last Name";
        }
    }
    catch (Exception ex)
    {
        throw ex;
    }
}

无论我采取哪种方式都没有影响。请提出我缺少的内容。

试试这个： -

if (e.Row.RowType == DataControlRowType.Header)
{
    e.Row.Cells[1].Text  = "Last Name";               
}

在这里，我已经硬编码了相应更改它所需的Cells值。

<强>更新： -
在RowDataBound中找到控件： -

if (e.Row.RowType == DataControlRowType.DataRow)
{
    Label txtNumber = (Label)e.Row.FindControl("txtNumber");
    txtNumber.ForeColor = System.Drawing.Color.Red;
}
