Selecting Children for Heirarchical view from a Generic Collection

Hi,

I'm sure you have addressed this somewhere before, but I could not find it.

I am assigning a generic collection as the DataSource of a RadGrid control. The Items in the collection have one member which is also a generic collection which provide the children.

For Example:

public class WorkOrderDetails

{

protected readonly IWorkOrder _workOrder;

protected readonly List<ResourceRequirement> _resources = new List<ResourceRequirement>();

public WorkOrderDetails(IWorkOrder wo)

{

_workOrder = wo;

foreach (IWoResources res in wo.ResourcesChildren)

{

_resources.Add(new ResourceRequirement(res));

}

public string WoNumber { get { return _workOrder.WoNumber; } }

public string Title

{

get { return _workOrder.Description; }

}

public List<ResourceRequirement> Resources

{

get { return _resources; }

}

public class ResourceRequirement

{

private IResources _data;

public ResourceRequirement(IResources res)

{

_data = res;

}



      //

      // Summary

      //    The Unique ID of this ResourceRequiment (which is a "Skill").

      public string ID { get { return _data.ResourceId; } }

//

// Summary:

// The property for the planned_hours column of the TabWare database wo_resources

// table.

public decimal PlannedHours { get { return _data.PlannedHours; } }

//

// Summary:

// The property for the remaining_hours column of the TabWare database wo_resources

// table.

public decimal RemainingHours { get { return _data.RemainingHours; } }

//

// Summary:

// The property for the workers column of the TabWare database wo_resources

// table.

public int Workers { get { return _data.Workers; } }

}

The assignment looks something like this:

List<WorkOrderDetails> list = factory.GetWorkOrders();

RadGrid1.DataSource = list;

My goal is to display the Work Orders with the ResourceRequirement children grouped under each WorkOrderDetail line.
For Example:

WoNumber    Title
000010202    Repair light fixture
      ID             Planned Hrs           Remaining Hrs            Workers
      Electician      8.0                         8.0                            1
      Welder          8.0                         8.0                            1

I figured out how to get the headers defined, but I currently have no content showing up for the child rows. Here is my markup:

<telerik:RadGrid

ID="rgPlannedWorkOrders" runat="server"

Width="480px" Height="392px"

AutoGenerateColumns="False" AllowSorting="True"

Skin="Sunset" GridLines="Vertical" CellSpacing="0"

AutoGenerateHierarchy="true">

<ClientSettings>

<Selecting AllowRowSelect="True" />

</ClientSettings>

<MasterTableView Width="100%"

HierarchyDefaultExpanded="True" HierarchyLoadMode="ServerBind">

<Columns>

<telerik:GridBoundColumn DataField="WoNumber"

FilterControlAltText="Filter WoNumber column" HeaderText="WoNumber"

ReadOnly="True" SortExpression="WoNumber" UniqueName="WoNumber">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Title"

FilterControlAltText="Filter Title column" HeaderText="Title" ReadOnly="True"

SortExpression="Title" UniqueName="Title">

</telerik:GridBoundColumn>

</Columns>

<DetailTables>

<telerik:GridTableView Name="SubLevel1" ShowHeadersWhenNoRecords="false" AutoGenerateColumns="false">

<%-- This level holds items of Type2 --%>

<Columns>

<telerik:GridBoundColumn DataField="ID"

FilterControlAltText="Filter ID column" HeaderText="ID"

ReadOnly="True" SortExpression="ResourceId" UniqueName="ID">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="PlannedHours" DataType="System.Decimal"

FilterControlAltText="Filter PlannedHours column" HeaderText="Planned Hrs" ReadOnly="True"

SortExpression="PlannedHours" UniqueName="PlannedHours">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="RemainingHours" DataType="System.Decimal"

FilterControlAltText="Filter RemainingHours column" HeaderText="Remaining Hrs"

ReadOnly="True" SortExpression="RemainingHours" UniqueName="RemainingHours">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Workers" DataType="System.Int32"

FilterControlAltText="Filter Workers column"

HeaderText="# Workers" ReadOnly="True" SortExpression="Workers"

UniqueName="Workers">

</telerik:GridBoundColumn>

</Columns>

</telerik:GridTableView>

</DetailTables>

<EditFormSettings>

<EditColumn FilterControlAltText="Filter EditCommandColumn column"></EditColumn>

</EditFormSettings>

<GroupHeaderItemStyle Height="32px" />

<RowIndicatorColumn FilterControlAltText="Filter RowIndicator column"></RowIndicatorColumn>

<ExpandCollapseColumn FilterControlAltText="Filter ExpandColumn column"></ExpandCollapseColumn>

</MasterTableView>

<GroupingSettings GroupContinuesFormatString="" GroupContinuedFormatString=""></GroupingSettings>

<FilterMenu EnableImageSprites="False"></FilterMenu>

<HeaderContextMenu CssClass="GridContextMenu GridContextMenu_Sunset"></HeaderContextMenu>

</telerik:RadGrid>

So, my question is: how do I tell the control to use the "Resources" property of the WorkOrderDetails item to fill the content of the second level of the heirarchy?

Please suggest solution for the above.

Tab Order From Grid to rest of page

I have a grid that is hidden when the page initially loads. So, the tab order is correct when the grid is hidden. The user clicks or presses a button and the grid appears with the results. Now the tab order is set to the first heading of the grid, which is correct. Then it tabs through the grid. But, after the grid instead of going to the menu on the page, it goes to some links on the bottom of the screen, then it goes to the browser URL, then the browser menu, which is not what I want to happen. Is there a way to keep the tab order the same when the grid is hidden or not? I'm not sure why it's going to the browser menu after the grid when it appears.

Thanks.

Expanding Problem in Firefox 4

Hello,

When I am using RadPanelbar all expanding and collapsing functions work well in IE and/or Chrome. But when I try it in Firefox 4 no expanding or collapsing occur. Here is my code :

<telerik:RadPanelBar ID="RadPanelBar1" runat="server" EnableEmbeddedSkins=

"false"

                Height="100%" ExpandMode="SingleExpandedItem" Skin="ShowCategory" Width="100%"

                AllowCollapseAllItems="false" OnClientItemClicking="OnClientItemClicking">

</telerik:RadPanelBar>

I am programmatically creating the items.

One more thing, in all other browser I can call OnClientItemClicking event but in FireFox 4.0 its not firing. FYI, added script below :

<script type="text/jscript"

        function OnClientItemClicking(sender, args) {

            debugger;

            if (args.get_item().get_level() == 0) {

                args.set_cancel(true);

               args.get_item().set_expanded(!args.get_item().get_expanded());

</script>

I am using Telerik 2010.1.519.35.

What can cause that problem? Any Idea?

Problem with AsyncUpload/Ajax Processing using MasterPage/ContentPage

I am following the Demo Project

AsyncUpload / Ajax Processing

In the demo, it states to setup the RadAjax Manager as such:

    <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

        <AjaxSettings>

            <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">

                <UpdatedControls>

                    <telerik:AjaxUpdatedControl ControlID="Thumbnail" />

                </UpdatedControls>

            </telerik:AjaxSetting>

        </AjaxSettings>

    </telerik:RadAjaxManager>

Since my Asych Upload control is in a Content Page, I am using an RadAjaxManagerProxy. My problem is if I set the AjaxContorlID to the Proxy's ID, I get a javascript error that I have nested Update Panels. If I set it to the MasterPage's RadAjaxManager ID, I get a javascript error that ID can't be found.

Here is my code.

MasterPage:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" ClientIDMode="Static"

DefaultLoadingPanelID="ralpDefault">

<ClientEvents OnRequestStart="centerLoadingPanel"></ClientEvents>

<AjaxSettings>

</AjaxSettings>

</telerik:RadAjaxManager>

Content Page:

<telerik:RadAjaxManagerProxy ID="rampMyAccount" runat="server" ClientIDMode="Static">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadAjaxManager1">

<UpdatedControls>
