Wondering about extra space to right of selected node?

I am trying to find out why the extra space shows up to the right of the highlighted node ( the node is in green in attached image). I would have liked the right border of the treeview to be very close to the right of highlighted node in green, but it is not so. May be there is some property of treeview that determines this?
I am using Q1 2008 SP1 version.

Thanks
Sunil

Changing the Indeterminate node image

Hi all,

I have a TreeView which is in TriState mode, which works fine but for one cosmetic issue. On every other TreeView I've used, any node which is in the "Indeterminate" state is filled-in so it looks like a solid box.

e.g. http://www.codeproject.com/KB/tree/Three_State_TreeView/ThreeStateTreeView2.png

However, in the Telerik TreeView, the node is a greyed-out tickbox. To my eyes though, this doesn't look distinctive enough. Can I make the Telerik TreeView achieve the same effect?

Thanks
Eddie

images dynamically set from Datatable setting?

Hi there,

When using the tree view I would like to set a node image depending on what I have specified in the datatabe. for intance I am doing the following:

1. I load a datset datatable from an SQL database
the columns in the Datatable are
ID, ParentID, Name, SQL_Query, Type

list is listed as follows with the binding:

FillSqlDs(

"TreeView_Reports", "Select * from SYSM_T_REPORT_TREE_VIEW ORDER BY NAME")

Me.TV_Reports.DataSource = ds.Tables("TreeView_Reports")

Me.TV_Reports.ValueMember = "ID"

Me.TV_Reports.ParentIDMember = "ParentID"

Me.TV_Reports.DisplayMember = "Name"

Me.TV_Reports.DataMember = "SQL_Query"

I would like to be able to set the image depending on the "Type". for instance I have 2 options here type = Folder or Type = Report. I want the node that corelates to "Folder" to display a folder image that i have in my images list (ImageID 0) and if Type = Report, then the node image should show that of a report Image (ImageID 1).

I also plan to have if I double click the folder, it will expand the node as it currently is, however if I double click the Report node it will spawn off a DataGridView in another form that I have loading into the RadDock MDI Container.

any help you could offer would be greatly appreciated.

Many thanks!

Nodes highlighting/disappearing issue

Hi all,

I am posting my response here as well for everyone's benefit. Since Q32009-SP1 release, we had intermittent reports about treenodes remaining as highlighted or even altogether disappearing briefly. Once this issue is seen, restarting the application or closing down other applications did not resolve this issue. However, rebooting the machines seems to have resolved this issue. I don't know what the problem is exactly but atleast there's the most popular workaround :)

Regards,
MP

How do I put image to left of checkbox?

When I am using a TreeView with checkboxes, how do I make the image show up on the left side of the checkbox instead of the right? When the image is enabled right now, it shifts the text to the right and puts the image between the checkbox and the text.

Hello experts!
Look, I have a radtreeview with a background image, but I need that that image always displays at the bottom left side of the control. How I can accomplish this?

Thank you for your help!

Can not add image to Winform radTreeView ImageList

I am using the Winform radTreeView. I am trying to add small PNG file (16x16) into the ImageList during design time. When press the Add button and choose an image from the file browser I get this error dialog that says this:

Parameter must be of type.
Parameter name: value

Is there something I have missed? i have set the color depth to 32 bit since it is a PNG file.

Thanks,
-TK

Size/position problem when radform starts minimized

Hi,

I opened a project just now and remembered that I had a problem that I thought I should mention:

I had a radform what had a radtab on it and 2 buttons. This form was started minimized to mimic system tray. The problem was when the form was restored to normal form, all controls shrunk and there was a wide horizontal band of space beneath the controls (the 2 buttons)

This behaviour was different on different machines (Win 7), probably because of the themes used, but always wrong.

I did not test it again because i changed strategy, but I thought i should mention it so you can correct it.
