radwindow repeater selection back to parent

[AName]

Hi there,

I have a radwindow that performs a search on data and displays a list within a repeater of options the user may select.
What I need to do is collect the repeater object and send back to the parent. 

I looked at some of your examples using javascript, the problem is using javascript to grab the data within the repeater is quite ugly.

Is there a way I can pass the code back via code behind?
So in my repeater I have a button "select" when user clicks the "select" button the radwindow closes and
the parent receives the selection. 

My repeater code

​<asp:Repeater ID="rptStores" runat="server" OnItemDataBound="rptStores_ItemDataBound">
<HeaderTemplate>
<table>
<tr style="color:#ffd700; font-weight:bold;">
<td>Store Name</td>
<td>City</td>
<td>Street</td>
<td>Distance(Mi.)</td>
</tr>
</HeaderTemplate>
<ItemTemplate>
<tr style="color:#fff;" onmouseover="this.style.backgroundColor='blue'" onmouseout="this.style.backgroundColor=''" class="<%# If(Container.ItemIndex Mod 2 = 0, "TRNormal", "TRAlt") %>">
<td style="padding: 4px;">
<asp:Label ID="lblDBAName" runat="server" Text='<%# Eval("DBAName") %>' />
<asp:HiddenField ID="hfRowID" runat="server" Value='<%# Eval("id") %>' />
</td>
<td style="padding: 4px;">
<asp:Label ID="lblCity" runat="server" Text='<%# Eval("State") +"-"+ Eval("City")%>' />
<asp:HiddenField ID="hfState" runat="server" Value='<%# Eval("state") %>' />
</td>
<td style="padding: 4px;">
<asp:Label ID="lblStreet" runat="server" Text='<%# Eval("Street1") %>' />
<asp:HiddenField ID="hfPhone" runat="server" Value='<%# Eval("phone") %>' />
</td>
<td style="padding: 4px;">
<asp:Label ID="lblDistance" runat="server" Text='<%# Eval("distance") %>' />
</td>
<td>
<telerik:RadButton runat="server" Text="Select" ID="storeSelection2" CommandName="Process" Skin="Black" OnClientClicked="returnToParent"></telerik:RadButton>
</td>
</tr>
</ItemTemplate>
<FooterTemplate>
<tr>
<td>
<asp:Label ID="lblEmptyData" Text="No Data To Display" runat="server" Visible="false"></asp:Label>
</td>
</tr>
</table>
</FooterTemplate>
</asp:Repeater>


my vb

Protected Sub rptStores_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.RepeaterCommandEventArgs) Handles rptStores.ItemCommand

Dim dbaName As Label
dbaName = CType(e.Item.FindControl("lblDBAName"), Label)

Dim city As Label
city = CType(e.Item.FindControl("lblCity"), Label)

Dim state As HiddenField
state = CType(e.Item.FindControl("hfState"), HiddenField)

Dim phone As HiddenField
phone = CType(e.Item.FindControl("hfPhone"), HiddenField)

Dim street1 As Label
street1 = CType(e.Item.FindControl("lblStreet"), Label)

Dim selectedID As HiddenField
selectedID = CType(e.Item.FindControl("hfRowID"), HiddenField)

ProcessButton(dbaName.Text, street1.Text, city.Text, state.Value, phone.Value, selectedID.Value)

End Sub

ProcessButton is called AFTER a return to parent javascript call.

Is this an option or do i really need to send object via javascript back to parent and then push into code behind.

Hello,

If the code in the RadWindow is in its own page, you can store data on the server, e.g., in the Session, so you can access it from the code-behind of the main page. You would still need some JavaScript to close the RadWindow and invoke a function on the main page that will POST it.

Another option is to use the ContentTemplate of the RadWindow so the repeater is a part of the main page, which will let you access all control in it. The following demo shows the difference in accessing the controls and lists the pros and cons: http://demos.telerik.com/aspnet-ajax/window/examples/contenttemplatevsnavigateurl/defaultcs.aspx. You may also find useful this article on using AJAX in this scenario: http://www.telerik.com/help/aspnet-ajax/radwindow-ajaxifying.html.

Hi Marin,

I tried putting in repeater inside RadWindow's ContentTemplate, but when saving the records, the values of the textbox inside repeater's itemtemplate is not according to what I put in, i.e. still the original data bound values. Is this a problem with the viewstate? Please find my code below. When I open the RadWindow, and change values in tbSequence, and hit a button click, the values are still the original databound values. Can you please advise?

<telerik:RadWindowManager ID="RadWindowManager1" runat="server">

Hi Julius,

This shouldn't be happening and my best suggestion at the moment is to move this RadWindow out of the RadWindowManager, because when its ContentTemplate is used, a change in the server lifecycle may occur, as described here.

Thanks Marin. It works fine now :)
