Hello

I am attempting to bind 3 tables of data to a Treeview using lists:

 

 

 

 

The last object rulesetsx does not bind ..please can you advise if I am on the right track.

Thanks

 

 

 

 

 

I was wondering if it's possible to use a TreeView as the drop-down of a combo box in win forms like you can in ASP.NET?

Hello,

i downloaded a trial version of your winforms 2009 / 2 for my future project and i am trying to understand this type of your product (i have experience with ASP.NET Controls)

But here I am not able to bind anything. I will need a treeview generated from database but when i am binding treeview step by step from your manual at http://www.telerik.com/help/winforms/tree_datadatabase.html and from your music collection database i have still empty form. At Visual Studio is everything fine - no errors or warnings, but when i debug that i have empty form. The same problem is with RadGrid, just columns name and no data. Display name i have defined. I really dont know what to do, bcs i tried everything what i know. I have Windows 7, VS 2005 SP1, .NET framework 3.5.

Thx for any help, i did not use C# so much.

Hi,

Is there any way to change the RadTreeNode look (or "style") based on the type of DataBoundItem ? For example, if the type of DataBoundItem is Person the RadTreeNode should be red and if the type of DatBoundItem is Address the RadTreeNode should be green (something like WPF DataTemplates).

Thanks in advance.

Hi Guys,

I am having a problem populating a RadTreeView with a Dataset that contains a DataRelation. As I step through the code the DataSet returns two tables and they both contain the correct values I want shown on the form, however, it only displays the first table’s data on my form. I am using the most current version of controls.

The following is a snippet of the source code that contains the problem described above:

private void LoadTreeView()

{

DataSet dsData = new DataSet();

int intDocID = 10;

tvrDocs.Nodes.Clear();

dsData = AppDocument.GetDocumentTreeView(intDocID);

if (dsData != null)

{

DataColumn parentColumn = dsData.Tables[0].Columns["DocGlobalRuleTypeID"];

DataColumn childColumn = dsData.Tables[1].Columns["DocGlobalRuleTypeID"];

// Create DataRelation.

DataRelation drGlobalVar;

drGlobalVar = new DataRelation("GlobalVar", parentColumn, childColumn);

// Add the relation to the DataSet.

dsData.Relations.Add(drGlobalVar);

tvrDocs.DataSource = dsData;

}

dsData.Dispose();

}

Please let me know what I can do to solve this issue.

Many Thanks,

Mike

Hi,

I am using a RadTreeView and a webbrowser (System.Windows.Forms.Webbrowser) on a form, the problem is that i need to set the themes of both control's scrollbars similar. Is there any way to set the treeview's scrollbars theme to system theme (which windows is currently using). And what is the probability of you to add a web browser control in Telerik suite.  

Thanks and regards

Hassan

I guess the title says it all. What I would like to do is dynamically replace the editing control used to edit nodes in the tree view, and only for specific nodes. Is there a way to do this?

The reason for doing this is to enable entering a phone number with an existing mask, and not force users to enter the mask as well. There's also a need to perform custom formatting on the value of the node when it is being displayed. For example, the stored value should be 3213214321 and displayed something like (321) 321-4321. How should I do that?

Hi Sir,

I have a problem on radtreeview, when the application is running and I'm exploring and clicking on radtreeview and sometimes just hanging on there and waiting for the response and update. the radtreeview suddenly crashing and the red mark "X" appeared over the radpanel bar. below is the detail of error. I hope for your immediate response on this. Thank you in advance  and God bless...

Hi Guys,

Can you add a button to a treeview node?

I need to give my client the ability fire an event on a specific node, but nice I have various other functionality tied into the tree already I don't really want to add a button below the tree to provide this event.

So...  Can I have a node like this.

Node Text  - (Button)

When the user clicks a button next to the node it fires off an event.  Maybe the button would select the node so I could get the info off the node tag.

Let me know.

I have set datasource of a tree view from a data table which is self referencing i.e. it contains columns id and parent id and so data is bind successfully. Now i have set property lableEdit = true for this radtreeview. and so when I press F2 and after I enter new text to the nodes I get error "Column ColName is ReadOnly." Where ColName is DisplayMember of this radTreeView. Thank you so far fast reply.
