Is there a way to make is so that when I have a group of items and I click to collapse the group, it collapses ALL of the items in the group - not just the visible items.

For example, say you have 2 groups. The first group has 150 items, the second has 25. My page size is 20. When I collapse group 1 (150 items), I want to immediately see group 2 and it's first 20 items show in the grid. Instead you just get a collapsed group and no items below it.

Thanks!

Show edit form by grouping the data

Hello

I have a RadGrid with one Group. The data is seperated by the groups in a proper way.
So from this point everything is ok.

Data should be added by an edit form (modal popup).
Now I try to display the edit form, but it's just appearing if I press "Add new record".
Pressing "Edit" in a row does not show the edit form.

If remove the grouping of the RadGrid, the edit form appears as expected!

What's the reason for this behaviour?

Here is my code:

    
                <asp:ScriptManagerProxy ID="ScriptManagerProxy1" runat="server">  
        
                </asp:ScriptManagerProxy>

Does Telerik RadTreeNode have some sort of tag property ?

Hi,

I have to create some RadTreeNodes programatically and I was wondering if the nodes have some sort of "tag" property ( like the tag property that controls in windows forms used to have ) ....

foreach(Student in students)
{
RadTreeNode treeNode = new RadTreeNode() { Text = Student.Name, Tag = Student.Id ??? }
}

Thanks.

RadListView- GroupBy dynamic selection

Hi,

I had designed ItemTemplate, LayoutTemplate, DataGroupTemplate in RadListView. Its working fine. Right now I am currently grouping by Date.

In my scenario, user can select groupby option either by 'Date' or 'Name'. I tried to declare two DataGroupTemplates, buts its throwing error 'RadListView doesn't have Item place holder specified' . I am pointing to the same ItemPlaceholder(Item Template) in both the DataGroups.

Is there a way to achieve this in RadListView, or should I create two RadListViews for each group and make visible/invisible accordingly.

Please advice,

thank you,

Madhavi

Batch Edit and Keyboard Navigation

I notice when I have Batch edit and Keyboard navigation, that hitting the ESC key fires the OnBatchEditCellValueChanging event if the value in the editor has changed. I handle this event to process the changed info, but I would think hitting the ESC key would cancel out of any changes. Otherwise, there really doesn't appear to be any way to prevent a changed status once any of the text has been modified.

IMO the ESC key should cancel any changes and take the cell/row out of edit mode without any changed values. Your thoughts? Is there any way to circumvent this behavior? Obviously, if the value is changed, I want to capture that in all instances... except when a user hits the ESC key.

Cant get templatecolumn to show the text of the selected item of a radcombobox in an edititemtemplate

I cant get the item template to reflect the text of the selected item in the radcombobox that is in the edititemtemplate of my programmatically created gridtemplatecolumn

Code for creating the template column:

01.Dim tempDB As New SqlDataSource

02.Dim templateColumnName As String = col.Caption

03.Dim templateColumn As New GridTemplateColumn()

04.

05.templateColumn.DataField = col.Caption

06.templateColumn.ItemTemplate = New LCDisp(templateColumnName, ddQuery, DiConnectionString)

07.templateColumn.EditItemTemplate = New DDEdit(templateColumnName, ddQuery, DiConnectionString)

08.templateColumn.HeaderText = templateColumnName

09.

10.templateColumn.UniqueName = col.Caption

11.

12.grdReport.Columns.Add(templateColumn)

Code for LCDisp template:

01.Private Class LCDisp

02. Implements ITemplate

03. Protected lblCont As Label

04. Private colname As String

05. Private DSQuery As String

06. Private DiConnectionString As String

07.

08. Public Sub New(ByVal cName As String, ByVal query As String, ByVal connString As String)

26. tempDB.SelectCommand = oQuery.SQLQuery

27. tempDB.ConnectionString = ConfigurationManager.ConnectionStrings(DiConnectionString).ConnectionString

28.

29. dv2 = tempDB.Select(DataSourceSelectArguments.Empty)

30. DropDown.DataSource = tempDB

31. If dv2.Table.Columns.Count > 1 Then

32. DropDown.DataTextField = dv2.Table.Columns.Item(0).Caption

33. DropDown.DataValueField = dv2.Table.Columns.Item(1).Caption

34. Else

35. DropDown.DataTextField = dv2.Table.Columns.Item(0).Caption

36. DropDown.DataValueField = dv2.Table.Columns.Item(0).Caption

Updating RadDiagram Data Sources

If RadClientDataSource is used for both the symbol and connection bound data sources, will the data sources, if they are to a SQL Server database, be updated when changes are made on the diagram; e.g. symbol title changed, new symbol or connection added, etc.?

If not, is there another approach or a relatively easy workaround to do this?

Thanks,

Donald
