In this demo I edited an occurrence of a recurring event. The event is to run from 1100-1200 the 2nd day of every month. I opted to create an exception and set the event to run from 1200-1300. Then I clicked the recurrence checkbox and clicked save.

As you might expect from the date of the initial exception forward I have 2 copies of the envent. One running 1100-1200 and the other from 1200-1300.

I seems to me that we don't really want recurrences set up as exceptions to existing recurrence events. I've (obviously) not been able to examine what has been written to the recurrence rule of the master event, but I'll bet it doesn't match the events that my actions caused to be created.

Is this a bug?

Do I win a prize? :-)

In the short term, why might be the best way, when adding/editing a recurrence exception, to hide the recurrence checkbox?

Problem with Ajax and disabled fields

By default, ASP.Net form submission will not pass back disabled field during postback. To get around this, we can set the form property "submitdisabledcontrols" to true and it will pass back the value of a disabled field. However I am having a problem with an Ajax postback as it does not contain the updated value of a disable field.

For example, I have a disabled checkbox when the form load. Through javascript, I enable the checkbox. Then I fire an event that makes an Ajax call to lookup a value. The Ajax call does a server side postback but the state of the checkbox is disabled.

Please help. Thanks.

Show insert item form automatically when grid is loaded

Hello,

I've got a grid with a custom EditForm in place for inserting records (update and delete are not allowed). Rather than requiring the user to press the Add New Row button, I'd prefer to just have the edit form displaying by default when the screen loads. They should be able to type in the form, commit it, and it will refresh itself with the new data and once again show another new item form.

I assumed there would be a C# command that I could call in Page_Load that would show this form but I was not able to find it. I would highly prefer to do this in C# rather than calling the client-side API with Javascript.

I did begin to create a separate form outside of the grid, but because of my layout it really makes more sense for the insert form to be inside the grid control itself.

Thanks in advance to anyone who can tell me how to do this!

Self-referencing hierarchy dynamicaly

I am trying to look for an example in VB on how to create a Self-referencing hierarchy grid dynamicaly. I have created one where i declare all the columns and parameters. However I want to create it entirly dynamicaly. I am already creating a standard grid in this manner, however I wish to add this option into the user control created.

I included some code, however would like to see an example if possible.

' the nestedDatasource is a dataset with a relation added

If NestedTable Then

RadGrid1.EnableLinqExpressions = False

RadGrid1.ClientSettings.AllowExpandCollapse = True

RadGrid1.MasterTableView.HierarchyDefaultExpanded = False

RadGrid1.MasterTableView.HierarchyLoadMode = GridChildLoadMode.ServerBind

RadGrid1.MasterTableView.SelfHierarchySettings.KeyName = NestedTableKey

RadGrid1.MasterTableView.SelfHierarchySettings.ParentKeyName = NestedTableParentKey

' RadGrid1.MasterTableView.SelfHierarchySettings.MaximumDepth = 0

Dim expandCollapseColumn As New GridExpandColumn

expandCollapseColumn.HeaderStyle.Width = 20

RadGrid1.MasterTableView.Columns.Add(expandCollapseColumn)

RadGrid1.MasterTableView.ShowHeader = False

RadGrid1.MasterTableView.HierarchyDefaultExpanded = False

Datasource = NestedDatasource.Tables(0)

End If

....

'create the columns dynamicaly from the dataset

boundColumn = New GridBoundColumn

RadGrid1.MasterTableView.Columns.Add(boundColumn)

boundColumn.DataField = column.ColumnName

boundColumn.HeaderText = column.ColumnName.Replace("_", " ").ToLower()

If colDataType = "int32" Then

boundColumn.DataFormatString = "<nobr>{0:N0}</nobr>"

boundColumn.ItemStyle.HorizontalAlign = HorizontalAlign.Center

.....

Protected Sub RadGrid1_NeedDataSource(ByVal source As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles RadGrid1.NeedDataSource

If NestedTable Then

RadGrid1.MasterTableView.VirtualItemCount = NestedDatasource.Tables(0).Rows.Count()

RadGrid1.DataSource = NestedDatasource

RadGrid1.Visible = True

Else

If Not Datasource Is Nothing Then

RadGrid1.MasterTableView.VirtualItemCount = Datasource.Rows.Count()

RadGrid1.DataSource = Datasource

RadGrid1.Visible = True

Else

RadGrid1.Visible = False

Exit Sub

End If

End Sub

Just a snippet, the issue I have with this is that when I click on the arrow, nothing expands. Not sure where I am going wrong here. Like I said I can get it working when not creating it dynamicaly. Also like to add, I am plugging this into a usercontrol that already creates a normal grid dynamicaly.

Just wondering If I need to do something extra?

I have own composite control inherited from RadWebControl. It contains RadTextBox control where I need handle keyup client event.
I have implemented client class for it and I attached event in initialize function. In dispose function I'm removing this event handler but it causes javascript error:

Line: 6

Error: '_events' is null or not an object

Here is the script:

nData.KnowledgeManagement.Web.UI.Searcher.prototype =

{

initialize: function () {

nData.KnowledgeManagement.Web.UI.Searcher.callBaseMethod(this, 'initialize');

// SearchTextBox

this._searchTextBox = $find(this.get_id() + '_searchTextBox');

this._keyUpDelegate = Function.createDelegate(this, this._keyUp);

$addHandler(this._searchTextBox._textBoxElement, "keyup", this._keyUpDelegate);

// XmlHttpPanel
