RadListView with a Repeater, problems with postback.

[Chris]

I am using a repeater within my RadListView which has the data source set like DataSource='<%# Bind("ContactDetails") %>'.

So then I can loop through the different properties of the ContactDetails and use them, but when I update any data in these fields the data is lost on post back.

I have read quite a lot of different blog posts etc and they seem to think I need to bind in the Onint method, but since I don't bind in the code behind, I have no idea how to do this, or if this will actually solve my problem.

The data source for the RadListView is calling a WCF web Service that expects JSON.

Here is an example of the code I am using....
Please ignore any small syntax errors, I have quickly shortend this code for putting on the forums.

<telerik:RadListView ID="RadListView1" runat="server" DataSourceID="ObjectDataSource1" Skin="Hay">
    <ItemTemplate>
        <asp:Repeater ID="ContactDetails" runat="server" DataSource='<%# Bind("ContactDetails") %>'>
            <ItemTemplate>
                <asp:Label ID="ContactDetailLabel" runat="server"
                    AssociatedControlID="ContactDetailTextBox"
                    Text='<%# Bind("ContactDetailType") %>'></asp:Label>
                <asp:TextBox ID="ContactDetailTextBox" runat="server" CssClass="rlvInput"
                    Text='<%# Bind("Value") %>' />
            </ItemTemplate>
        </asp:Repeater>
        <asp:Button ID="UpdateButton" runat="server" CommandName="Update"
            Text="Update Profile" ToolTip="Update" />
    </ItemTemplate>
</telerik:RadListView>

Any help would be great, I am totally stuck on this one. Is it even possible to do what I want?

Hi Chris,

The data is lost because the Repeater creates new controls when it is bound during the postback, so the ContactDetailTextBox will get the value from the datasource again.
You need to use a control that actually supports data editing like RadGrid or RadListView and not Repeater control.

Hi,

Thank you very much for the reply :)

So is it going to be as simple as replacing the repeater with a RadListView?

Hi Chris,

Yes, it should be okay. You can write here if you have some problems using the ListView after migrating the project.

All the best,
