Question

I have a repeater control in which i am showing values from database and i need to do sorting using a link button

Here is my code

<div class="demo">
<ul id="sortable1" class="connectedSortable" style="border-style: groove; border-width: inherit;border-color: #D4D0C8; height: 100%; width: 170px;">
<asp:LinkButton ID="LinkButton2" runat="server" onclick="LinkButton2_Click"   >LinkButton</asp:LinkButton>&nbsp;&nbsp;&nbsp;&nbsp;
<asp:Repeater ID="rpt1" runat="server" DataSourceID="sqlDataSource1">
<ItemTemplate>
<li class="ui-state-default" >
<%# DataBinder.Eval(Container.DataItem, "code") %>
&nbsp;&nbsp;
<%# DataBinder.Eval(Container.DataItem, "regon_name") %>
</li>
</ItemTemplate>
</asp:Repeater>
</ul>
</div>

and

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:DB_CGTPO_DEVEConnectionString %>"
SelectCommand="SELECT * FROM [region_test] ORDER BY [code], [regon_name]"></asp:SqlDataSource>

Any suggestions?

Answer 1

rapidly, you could add an event in these likn buttons and change the select command, something like this:

public void LinkButton2_Click(object sender, EventArgs e) 
{
   //set the new select command with a ordery by
   SqlDataSource1.SelectCommand = "SELECT * FROM [region_test] ORDER BY [regon_name]";

   //refresh the repeater
   rpt1.DataBind();
}

Yo can add an event for every button and apply the order by command!
This link shows a nice way to do it as well with repeaters (using ViewState to save the state of order by):
