Data not bound again after postback on dynamically-loaded RadGrids

I have a project in which I have a hierarchical RadGrid contained within a UserControl (usrAccountOverview.ascx). There is an aspx page that dynamically loads a number of these UserControls based upon which option a user selects in a DropDownList. The RadGrid binds data just fine at the top of the hierarchy, and if you expand one top-level item in the hierarchy binding works fine within the DetailTable as well. However, if the page posts back, none of the previously bound data reappears in any expanded DetailTables.

Here is the declarative code for the RadGrid

    
                <telerik:RadGrid ID="rgMonthly" runat="server" GridLines="None" OnColumnCreated="rgMonthly_ColumnCreated" 
        
                    OnDetailTableDataBind="rgMonthly_DetailTableDataBind" OnItemDataBound="rgMonthly_ItemDataBound" 
        
                    OnNeedDataSource="rgMonthly_NeedDataSource"> 
        
                    <MasterTableView DataKeyNames="GroupID"> 
        
                        <DetailTables> 
        
                            <telerik:GridTableView Width="100%" runat="server" DataKeyNames="GroupID"> 
        
                                <ParentTableRelation> 
        
                                    <telerik:GridRelationFields DetailKeyField="GroupID" MasterKeyField="GroupID" /> 
        
                                </ParentTableRelation> 
        
                            </telerik:GridTableView> 
        
                        </DetailTables> 
        
                    </MasterTableView> 
        
                </telerik:RadGrid>

I am loading the UserControls in the Page_Init method of the aspx page and binding them as in the following:

    
                protected void Page_Init(object source, System.EventArgs e) 
        
                { 
        
                    BindSelectedInfo(); 
        
                } 
        
                protected void BindSelectedInfo() 
        
                { 
        
                    try 
        
                    { 
        
                        DTSelectedAccts = TAAcctPi.GetData(Int32.Parse(Session["id"].ToString())); 
        
                        for (int i = 0; i < 1; i++) 
        
                        { 
        
                            dsAccountProjections.dtAcctPiRow SelectedAcct = DTSelectedAccts[i]; 
        
                            usrAccountOverview AccountOverview = (usrAccountOverview)LoadControl("~/usrAccountOverview.ascx"); 
        
                            AccountOverview.ID = "usr" + SelectedAcct.SlAcct6Num; 
        
                            AccountOverview.Acct.AcctNum = SelectedAcct.SlAcct6Num; 
        
                            AccountOverview.PullAcctInfo(); 
        
                            pnlHolder.Controls.Add(AccountOverview); 
        
                        } 
        
                    } 
        
                    catch (Exception ex) 
        
                    { 
        
                    } 
        
                } 
        
                protected void rgMonthly_NeedDataSource(object source, GridNeedDataSourceEventArgs e) 
        
                { 
        
                    if (!e.IsFromDetailTable) 
        
                    { 
        
                        rgMonthly.DataSource = DMonthlyExpenditures.GetMonthlyExpendituresByGroup(_Acct.AcctNum, firstMonthID, lastMonthID, lastMonthID); 
        
                    } 
        
                } 
        
                protected void rgMonthly_DetailTableDataBind(object source, GridDetailTableDataBindEventArgs e) 
        
                { 
        
                    GridDataItem parentItem = e.DetailTableView.ParentItem; 
        
                    DataTable dtBind = DMonthlyExpenditures.GetMonthlyExpendituresBySubAcct(_Acct.AcctNum, firstMonthID, lastMonthID, lastMonthID, Int32.Parse(parentItem["GroupID"].Text)); 
        
                    if (dtBind.Rows.Count > 0) e.DetailTableView.DataSource = dtBind; 
        
                }

Is there some way of getting this to work?

Thanks,

Brian

Problem Script registering and RadGrid edit mode

Hi...

I'm trying to dynamically register some client script in a user control Page_Load method... This user control is triggered by a RadGrid through the EditMode...

AJAX SETTINGS :

    
            <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
        
                  <AjaxSettings > 
        
                      <telerik:AjaxSetting AjaxControlID="RadGrid1" > 
        
                            <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="RadGrid1"/>  
        
                           </UpdatedControls> 
        
                          </telerik:AjaxSetting> 
        
                    </AjaxSettings> 
        
                </telerik:RadAjaxManager>

GRID :

    
             <telerik:RadGrid ID="RadGrid1" runat="server">  
        
                    <MasterTableView Name="masterView" GridLines="None" EditMode="PopUp" CommandItemDisplay="Top">  
        
                        <CommandItemSettings AddNewRecordText="Add new entry" RefreshText="Refresh" /> 
        
                        <EditFormSettings UserControlName="Control1.ascx" EditFormType="WebUserControl">  
        
                        </EditFormSettings> 
        
                    </MasterTableView> 
        
                </telerik:RadGrid>

USER CONTROL UI

    
            <%@ Control Language="vb" AutoEventWireup="false" CodeBehind="Control1.ascx.vb" Inherits="TestClientScriptRegister.Control1" %> 
        
            <asp:Button ID="Button1" runat="server" Text="Button" />

USER CONTROL SERVER SIDE CODE

    
             Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load  
        
                Me.Page.ClientScript.RegisterClientScriptBlock(GetType(String), "Test", Me.GetScript(), True)  
        
                Me.Button1.Attributes("OnClick") = "Test()" 
        
              End Sub 
        
              Private Function GetScript() As String 
        
                Dim sb As New System.Text.StringBuilder()  
        
                sb.Append("function Test() {")  
        
                sb.Append("alert('what?');")  
        
                sb.Append("}")  
        
                Return sb.ToString()  
        
              End Function

Quite basic stuff... I know that there's some ways to achieve this without any dynamic script registering but for some reasons, I need to do it that way...
I tried a bunch of stuff without any success...
- EnablePageHeadUpdate = "true" in the AjaxManager
- RadScriptManager.RegisterClientScriptBlock
- Page.ClientScript.RegisterClientScriptBlock
- RadAjaxManager.GetCurrent(Page).ResponseScripts

Some remarks...
- Works well when using a radwindow that calls a page containing the user control.
- Works well when I remove the ajaxsettings that update the RadGrid in the RadAjaxManager.

Am I missing something? Maybe I'm not using the grid edit mode the right way... Is there a way to achieve this?

Thanks for your help : )

Adding ItemTemplate Dynamically

I am really having trouble adding a template field to a RADGRID in my cs file. Here is what I have:

[Solved] RadMenu layer on top of Window

I am using both your RadMenu and Rad Window. When I open a new RadWindow the RadMenu is on top of the window.

How do I get the menu to stay behind the window? Where is the layer setting if that is what it is to set it to be behind the RadWindow?

Binding Grid DropDownList to IList

I am using a dropdown field in a RadGrid to edit/save a value to a database field. The edit method is via popup. The dropdown list is populated in code behind with the list of the names associated with the values. This is a general concept used in many business models. The data itself is not important to this discussion, only that I am using name/value pairs. The names should be displayed in the dropdown and the values go back and forth to the database. Here is the aspx code setting up the grid column:

    
                        <telerik:GridDropDownColumn DataField="StartRndType" Visible="false" HeaderText="<%$ Resources:TCRS, Start %>" 
        
                            EditFormColumnIndex="0">  
        
                        </telerik:GridDropDownColumn>

Here's the code behind:

    
                    protected void grdRndPolicy_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)  
        
                    {  
        
                        if (e.Item is GridEditableItem && e.Item.IsInEditMode)  
        
                        {  
        
                            // get the editedItem (row)  
        
                            GridEditableItem eeditedItem = e.Item as GridEditableItem;  
        
                            GridEditManager editMan = editedItem.EditManager;  
        
                            // get the record  
        
                            RoundPolicyT dataRecord = e.Item.DataItem as RoundPolicyT;  
        
                            // safety check  
        
                            if (dataRecord == null)  
        
                                return;  
        
                            GridDropDownListColumnEditor editor;  
        
                            // All 7 rounding type dropdowns use the same item list -  
        
                            // it does not appear to be necessary to make a new copy for each control  
        
                            IList<ListItem> items = new List<ListItem>();  
        
                            items.Add(new ListItem(Resources.TCRS.Forward, "1"));  
        
                            items.Add(new ListItem(Resources.TCRS.Nearest, "2"));  
        
                            items.Add(new ListItem(Resources.TCRS.Backward, "3"));  
        
                            // Start Rnd Type dropdown  
        
                            editor = editMan.GetColumnEditor(_STARTRNDTYPE) as GridDropDownListColumnEditor;  
        
                            editor.DataSource = items;  
        
                            editor.DataBind();  
        
                            editor.SelectedValue = dataRecord.StartRndType.ToString();

The problem I have is that once the editor.DataSource is set, all the Name values are the same as the Value values, so my SelectedValue is not in the list. I have tried using a NameValueCollection instead of an IList but that had no effect. I also tried using a GridDropDownColumnEditor but that had no effect. Somehow setting the DataSource and doing DataBind causes the dropdown list to be populated with just the Name value. The Name/Value should be different (one the item name, one the item value).
My question is, how do I get the dropdown to populate with the Name/Value pairs?

Advanced InlineInsertTemplate

Hi,

I am trying to create an advanced InlineInsertTemplate. I want the user to be able to select the appointments start and end date/time. Maybe even give the user the opportunity to select a resource for the appointment. If I can get my head arround it!?

I have pasted my InlineInsertTemplate code where I try to do the date and time thing. The problem in this case is that if I choose a start and end time, that differ from each other, the date gets destroyed in month view. The date is totally different from the one I choose.

I suspect that it's the way i Bind the controls. But what do I do? And how would I let users choose a resource?

    
            <InlineInsertTemplate> 
        
                  <div id="rsAppointmentEdit" style="background:#fff;">
