Asp.NET网格视图是一个用于显示和编辑数据的强大控件。要实现只显示最新行的删除选项,并且能够查看具有数据填充功能的单选按钮的选定索引更改,可以按照以下步骤进行操作:
下面是一个示例代码:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" OnRowDeleting="GridView1_RowDeleting" OnRowDataBound="GridView1_RowDataBound">
<Columns>
<asp:CommandField ShowDeleteButton="True" />
<asp:TemplateField>
<ItemTemplate>
<asp:RadioButtonList ID="RadioButtonList1" runat="server" AutoPostBack="True" OnSelectedIndexChanged="RadioButtonList1_SelectedIndexChanged">
<asp:ListItem Text="Option 1" Value="1"></asp:ListItem>
<asp:ListItem Text="Option 2" Value="2"></asp:ListItem>
<asp:ListItem Text="Option 3" Value="3"></asp:ListItem>
</asp:RadioButtonList>
</ItemTemplate>
</asp:TemplateField>
<!-- Add other columns as needed -->
</Columns>
</asp:GridView>
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
// Perform necessary operations before deleting the row
// For example, check if only the latest row is displayed
// Delete the row
GridView1.DeleteRow(e.RowIndex);
}
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
RadioButtonList radioButtonList = (RadioButtonList)e.Row.FindControl("RadioButtonList1");
radioButtonList.SelectedIndexChanged += RadioButtonList1_SelectedIndexChanged;
}
}
protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)
{
// Perform necessary operations when selected index changes
}
这是一个简单的示例,你可以根据实际需求进行修改和扩展。关于Asp.NET网格视图和相关控件的更多信息,你可以参考腾讯云的文档和产品介绍:
