C# – Change repeater row value

asp.netcitemdataboundrepeaterwebforms

im trying to change a value inside my repeater : (via itemdatabound event)

if the year is empty – set value blabla

my repeater :

 <ItemTemplate>
                <tr  >
                    <td  >
                        <%#Eval("year") %>
                   </td>

my c# code : 

 void RPT_Bordereaux_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
            if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            if (string.IsNullOrEmpty(((DataRowView)e.Item.DataItem)["year"].ToString()))
            { 
                (((DataRowView)e.Item.DataItem)["year"]) = "blabla"; // ???????

            }
        }

it does change but not displayed in repeater ( the old value is displayed).

one solution is to add a server control or literal ( runat server) in the itemTemplate – and to "findControl" in server – and change its value.

other solution is by jQuery – to search the empty last TD.

but – my question :

is there any other server side solution ( ) ?

Best Answer

you can try something like this :

Repeater in .aspx:

<asp:Repeater ID="Repeater1" runat="server">
    <ItemTemplate>
    <table>
    <tr>
          <td> <%# GetText(Container.DataItem) %></td>
    </tr>

    </table>
    </ItemTemplate>
</asp:Repeater>

.cs : 

 protected static string GetText(object dataItem)
 {
    string year = Convert.ToString(DataBinder.Eval(dataItem, "year"));
    if (!string.IsNullOrEmpty(year))
    {
        return year;
    }
    else
    {
        return "blahblah";
    }

 }

IN GetText Method you can able to check by string that Empty or not than return string.
