Display DataList Row (Item) details in TextBox on Button click in ASP.Net

Hi,

I have a datalist control which uses repeatcolunm. I want to make Datalist items clickable and get the clicked item value into a textbox outside the datalist. I did this and it works only when I set "RepeatLayout="flow"" which cancels the "repeatcolunm" which is very necessary in my case. Below is code:

 <asp:DataList ID="DataList1" runat="server" DataSourceID="SqlDataSource2" RepeatDirection="Horizontal" ShowFooter="False" ShowHeader="False" RepeatColumns="21"     OnItemDataBound="DataList1_ItemDataBound"  OnItemCommand="DataList1_ItemCommand" >
                      
                      <ItemStyle Font-Bold="True" Font-Italic="False" Font-Overline="False" Font-Strikeout="False" Font-Underline="False"/>
                      <ItemTemplate>
                          <asp:LinkButton id="SelectButton"  Text="select"  CommandName="Select" runat="server" style="display:none"/>
                         <a href="#"> <asp:Label ID="SpotNameLabel" runat="server" Text='<%# Eval("SpotName") %>' CssClass=" badge" /></a>
                         
                          <br />
                    <br />
                      </ItemTemplate>
                      <SeparatorStyle Font-Bold="False" Font-Italic="False" Font-Overline="False" Font-Size="Large" Font-Strikeout="False" Font-Underline="False"  />
                  </asp:DataList>

C#:

 protected void DataList1_ItemDataBound(object sender, 
                             DataListItemEventArgs e) 
{
     if (e.Item.ItemType == ListItemType.Item || 
         e.Item.ItemType == ListItemType.AlternatingItem)
     { 
         //Add eventhandlers for highlighting 
         //a DataListItem when the mouse hovers over it.
         e.Item.Attributes.Add("onmouseover",
                "this.oldClass = this.selectedSeat;" +
                " this.selectingSeat = 'EntryLineHover'"); 
         e.Item.Attributes.Add("onmouseout",
                "this.selectingSeat = this.oldClass;");
         //Add eventhandler for simulating 
         //a click on the 'SelectButton'
         e.Item.Attributes.Add("onclick", 
                this.Page.ClientScript.GetPostBackEventReference(
                e.Item.Controls[1], string.Empty));
     }
}

       protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)
       {
           txtSpotNo.Text =((Label)e.Item.FindControl("SpotNameLabel")).Text;
       }
