Handling control events from Repeater footer
Assuming I have the following repeater.
<asp:Repeater ID="MyRepeater" runat="server" onitemdatabound="MyRepeater_ItemDataBound">
<FooterTemplate>
</table>
<asp:Button ID="btnPrevious" runat="server" Text="<" />
<asp:Label ID="lblCurrentPage" runat="server" Text="<%# PagingStatus() %>" />
<asp:Button ID="btnNext" runat="server" Text=">"开发者_StackOverflow中文版 />
</FooterTemplate>
</asp:Repeater>
How can I handle the click events from btnPrevious
and btnNext
?
I have tried the following:
protected void MyRepeater_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
Button btnPrevious = (Button)e.Item.FindControl("btnPrevious");
Button btnNext = (Button)e.Item.FindControl("btnNext");
if (btnPrevious != null)
btnPrevious.Click += btnPrevious_Click;
if (btnNext != null)
btnNext.Click += btnNext_Click;
}
But this has failed (The event is never raised)..
You can use them in the same way you would use a normal button event handler eg:
Html:
<asp:Button ID="btnNext" runat="server" CommandArgument="<%=Id%>" onclick="Button_OnClick" Text=">" />
Code:
protected void Button_OnClick(object sender, EventArgs e)
{
Button button = sender as Button;
if(button != null)
{
string commandArg = button.CommandArgument;
//Do Work
}
}
The you can use the command argument to find out which button was clicked.
Hope this helps.
I would suggest using the ItemCommand event of the repeater. You still have to add the commands to your buttons though. Like this:
<asp:Button ID="btnPrevious" runat="server" Text="<" CommandName="Previous"/>
protected void MyRepeater_ItemCommand(object source, RepeaterCommandEventArgs e)
{
if(e.CommandName.ToLower().Equals("previous")) {
//go back
}
else
{
//go forward
}
}
