I have a collection of say invoices that has a collection of invoice details or line items and a collection of payements.  I want to bind the gridview to the collection without manually creating all of the columns and such.  When I use the Invoice collection as the datasource I do not get the children of invoice, only the single column.  I am setting autoGenerateHeirarchy.  Do I need to define the relationships to accomplish this, even though they are well defined already?

Thanks

I'm having an issue with  RadGridView1_RowsChanged event. Normally this event will trigger if I modify the row content and moved to another row. If the row contains a cell with NULL values and I clicked on that cell and without editing I moved to another row, then also the RadGridView1_RowsChanged event triggered which is causing me issue. What I'm trying to do in my project is that I need to get the edited row details and update that to database on a button click. If I go through a null cell and moved to another row then also RadGridView1_RowsChanged event triggerd and my edited row index valu will change and I'm not able to save the details to database.  Some part of my code is given below. Can anybody help me?

Can you tell me how I get the grid view to wrap text and force the height of the cell to match the amount of text - IE exactly like in Excel where you select cell properties and select "wrap text"??

I really need a solution that is defined in the front end like the show/hide columns, expand widths etc, so the settings can be saved on the users end.

Can you tell me what i am looking for to achieve this?

Thanks

Hi Experts,

I add decimal columns into my grid. My application is base on the example GridView/Columns/Column type example.

My problem is when I try to set the appropriate DecimalPlaces no change appear to the grid view. For example, it show 500.000 instead of 500.

I try to do a modification to the code of the Telerik Grid example and change the numeric column decimal places from 0 to 2 and I got the same result then in my application; decimal place didn't change and the numeric column still show 0 decimal places...

What I am doing incorrectly?

Thanks
Nadia

If I set the

 

 

MasterGridViewTemplate.AddNewRowPosition =

PinnedRowPosition.Top, then the Value changing event does not fire. It fires only if it is set to bottom... Please advise


Thanks

Hi,

I follow this code: http://www.telerik.com/support/kb/winforms/combobox/implementing-checkbox-items-in-radcombobox.aspx

and i could fill the combo well.

But now i cant know if one item is checked or not..
This line gives me the content of the item: MItem= RadComboBox1.Items(i).Text
but i cant know if its check or not. How can i know that?

Best regards

we want to use web form scheduler for adding recurring appointment and save it in a database  and

We want a winform application to use scheduler to retrieve the same database  and use the data .

We tried it and found that the recurring appointments are saved in different manner  in winform and webform in the table .

is ther a way to make both controls save the data in the same manner . So that both asp.net  application and windows winform application can use the same data ?

Hi - I am having a strange problem when using hostedcontrols with radtreeview.  Replicate by dragging a new radtreeview onto a vb.net form.  Set AllowArbitraryItemHeight to true, and then add code to add some nodes with some hostedcontrols containing radpanels.  When I run the app, a radpanel appears incorrectly at the very upper left of the treeview.  Then I scroll to the bottom, and back up to the top, and the mystery panel disappears.  Also, when I expand / collapse nodes, it all seems to go a bit haywire.  Using 2010.1.10.308 and VS2008 / VB.NET. Any ideas?  Thanks!

Here is code to replicate the problem:

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Dim viewParentNode(3) As Telerik.WinControls.UI.RadTreeNode
viewParentNode(1) = New Telerik.WinControls.UI.RadTreeNode("Level1")
viewParentNode(2) = New Telerik.WinControls.UI.RadTreeNode("Level2")
viewParentNode(3) = New Telerik.WinControls.UI.RadTreeNode("Level3")

Dim viewChildNode(5) As Telerik.WinControls.UI.RadTreeNode
viewChildNode(1) = New Telerik.WinControls.UI.RadTreeNode("sub 1")
viewChildNode(2) = New Telerik.WinControls.UI.RadTreeNode("sub 2")
viewChildNode(3) = New Telerik.WinControls.UI.RadTreeNode("sub 3")
viewChildNode(4) = New Telerik.WinControls.UI.RadTreeNode("sub 4")
viewChildNode(5) = New Telerik.WinControls.UI.RadTreeNode("sub 5")

Dim thumbnailPanel(5) As Telerik.WinControls.UI.RadPanel
Dim viewImageNode(5) As Telerik.WinControls.UI.RadTreeNode
For i = 1 To 5
thumbnailPanel(i) = New Telerik.WinControls.UI.RadPanel
thumbnailPanel(i).Height = 61
thumbnailPanel(i).Width = 100
viewImageNode(i) = New Telerik.WinControls.UI.RadTreeNode
viewImageNode(i).HostedControl = thumbnailPanel(i)
viewImageNode(i).ItemHeight = "75"
viewImageNode(i).Expanded = True
viewChildNode(i).Nodes.Add(viewImageNode(i))
Next

viewParentNode(1).Nodes.Add(viewChildNode(1))
viewParentNode(1).Nodes.Add(viewChildNode(2))
viewParentNode(2).Nodes.Add(viewChildNode(3))
viewParentNode(2).Nodes.Add(viewChildNode(4))
viewParentNode(3).Nodes.Add(viewChildNode(5))

For i = 1 To 3
RadTreeView1.Nodes.Add(viewParentNode(i))
Next

RadTreeView1.ExpandAll()
RadTreeView1.Refresh()

End Sub

Simply, I need to make a toolstrip with large imagebuttons, for example 30x30, and I need to have more space between buttons.

How to do it? Thank you.

Stefano.

When first opening a form with a new type of RadControl on it (like a RadGrid or a RadDock), the form takes several seconds to load (about 4 seconds on my AMD Phenom II X2 550). Subsequent forms with the same controls open nearly instantly (I have a MDI application). I understand that there might be some one-time initialization going on, but 4 seconds on a fairly decent modern CPU is a bit annoying. I'm worried about my clients who might not have the latest hardware (to put it mildly). Is there anything that can be done to speed up this process?
