Details grid binding to the MasterTableView Datasource by default?

I am building a Nested Detail grid programmatically in code behind only.
Sometimes the parent rows will have nested child data and sometimes they wont.

It appears that by default the details GridTableView is binding to the entire dataset of the MasterTable view (several hundred records).
I am using the "GridDetailTableDataBindEventHandler" for the detail grid and "GridNeedDataSourceEventHandler" for the MasterTable View.

Can anyone explain this to me? Is it by design that the Nested Grid (I can see the datasource "count" as I step through the code - so I know what its doing) but it doesn't make any sense.

I did find something that (perhaps) states that this is by design - but its very convoluted and confusing:
http://demos.telerik.com/aspnet-ajax/grid/examples/programming/hierarchy/defaultcs.aspx
"When RadGrid constructs each copy of the detail tables, it assigns its data-source of the grid itself. This is useful when the data source is a DataSet containing all the detail table data. Using the DetailTableDataBind() method, you can obtain the instance of the DataSet from the DataSource property of the detail table that is an argument of the event handler (referred to as e.DetailTable). Prior to rebinding MasterTableView or any detail tables, RadGrid fires NeedDataSource event, so the developer can assign a DataSource. Note that it will be fired only once for a group of detail tables and only if the DataSource of RadGrid is not already assigned."

My approach has been to pass 'dummy' values of zero to the datasource if there shouldn't be any nested data - very clunky and not what I was looking for...

my code behind (pertinent stuff only) is below:

// build the grids MasterTableView in OnInit (this sits in a SharePoint 2010 webpart)

_radGridViewSearch = new Telerik.Web.UI.RadGrid();

// advanced data filtering

_radGridViewSearch.NeedDataSource += new GridNeedDataSourceEventHandler(radGridViewSearch_NeedDataSource);

_radGridViewSearch.Skin = "Sunset";

_radGridViewSearch.AutoGenerateColumns = false;

_radGridViewSearch.AllowPaging = true;

_radGridViewSearch.AllowSorting = true;

_radGridViewSearch.PagerStyle.Mode = GridPagerMode.Slider;

_radGridViewSearch.PageSize = 25;

_radGridViewSearch.AllowFilteringByColumn = true;

// per telerik: Depending on the data source, the filtering may be case-sensitive or case-insensitive. You can control this behavior using the GroupingSettings-CaseSensitive property

_radGridViewSearch.GroupingSettings.CaseSensitive = false;

// per telerik: In some .NET 3.5 scenarios you should also turn off the Linq expressions - EnableLinqExpressions="false"

_radGridViewSearch.EnableLinqExpressions = false;

_radGridViewSearch.MasterTableView.TableLayout = GridTableLayout.Auto;

// build the detail tableview - if the report needs one

if (_genReport.HasDetailsView)

{

// use 'ServerBind' so that the DetailTableDataBind event fires immediately after the corresponding parent item is bound

// Assign the DetailTableDataBind event handler to the grids nested matters

_radGridViewSearch.DetailTableDataBind += new GridDetailTableDataBindEventHandler(_radGridViewSearch_DetailTableDataBind);

_radGridViewSearch.MasterTableView.HierarchyLoadMode = GridChildLoadMode.ServerBind;

_detailsView = new GridTableView();

_detailsView.HierarchyLoadMode = GridChildLoadMode.ServerBind;

_detailsView.AllowPaging = false;

_detailsView.AllowSorting = false;

_detailsView.AllowFilteringByColumn = false;

_detailsView.Width = Unit.Percentage(95);

_detailsView.HorizontalAlign = System.Web.UI.WebControls.HorizontalAlign.Right;

_radGridViewSearch.MasterTableView.DetailTables.Add(_detailsView);

}

void _radGridViewSearch_DetailTableDataBind(object sender, GridDetailTableDataBindEventArgs e)

{

try

{

// grab the 'parent item'

GridDataItem targetParentItem = (GridDataItem)e.DetailTableView.ParentItem;

int targetParentMatterID = 0;

string targetChildMatter = "0";

_lionRepository = new LionBCSRepository();

// first, prep the parent matter ID and make sure we have something that we can work with

if (!string.IsNullOrEmpty(Convert.ToString(targetParentItem["MatterID"].Text))

&& (int.TryParse(targetParentItem["MatterID"].Text, out targetParentMatterID)))

{

// next, prep the related matter ID and make sure we have something that we can work with

if (!string.IsNullOrEmpty(Convert.ToString(targetParentItem["RelatedMatter"].Text))

&& !string.Equals(" ", Convert.ToString(targetParentItem["RelatedMatter"].Text), StringComparison.OrdinalIgnoreCase))

{

// once we're here we know that we have something to work with for both the parent and child matters

targetChildMatter = targetParentItem["RelatedMatter"].Text;

// setup the datasource

e.DetailTableView.DataSource = _lionRepository.GetRelatedMatters(targetChildMatter, targetParentMatterID);

}

else

{

e.DetailTableView.DataSource = _lionRepository.GetRelatedMatters(targetChildMatter, targetParentMatterID);

}

else

{

e.DetailTableView.DataSource = _lionRepository.GetRelatedMatters(targetChildMatter, targetParentMatterID);

}

catch (Exception ex)

{

LionExceptionLogging.LogException("WebParts", string.Format("LION SS exception at _radGridViewSearch_DetailTableDataBind: {0} Details: {1}", ex.Message, ex.InnerException));

this._LitError.Visible = true;

this._LitError.Text += ex.Message;

}

Stop the selection of a day in month view

Hello Telerik team,
is it possible to stop the selection of a day in month view?
I'm using the Scheduler control and I'm using the OnClientTimeSlotClick property to overwrite the behaviour of the scheduler control when a day in the month view is clicked (I'm generating an own ajax request, save the selected day in the session variable and use an own css class to change the background of this day in the month view).
This works fine.

Furthermore I have supressed the default behaviour if the day in the date header is clicked, so the scheduler will not change to the day view with the selected day.
This works fine also.

But one problem is still there. If the date header of a day in month view is now clicked (NOT the day number and NOT one of the other <tr> which are used to render the day in the month view), then the hole day will have assigned the 'rsSelected' css class (and in my example a deep blue background will be use), BUT the OnClientTimeSlotClick event WILL NOT FIRE. That means my own javascript function will not be called AND the new selected day will not be saved in the session variable.

Is there a way to prevent this? I mean to fire the right event so my own java function for the OnClientTimeSlotClick event will be called?

Greetings,
Richard Huber.
