How can i loop through the RadTreeView all node. Which i can get the node name and node is checked or not?

Im using Q2 2010 Telerik for WinForm.

p/s:
Currently my project is running under (Trial) Q2 2010 Telerik for WinForm, I already purchased the Q1 2011

May i know what should i do?
Uninstall Q2 2010 and Install Q1 2011? or Direct install Q1 2011?
Will that effect my project?

How can I prevent the user from clearing out the textboxes in the DateTimePicker?  For example, I always an actual date displayed in the textbox at all times.  Right now, a user can hit the "Delete" key and clear it out, even if MinDate is set.  The value will return the last "good" date thought.

Thank you!

Hello,
Is there a way to add a non-telerik control in a radgridview?
Thank you

When setting allow add new rows to false in my template, the template disappears when I run it in debugger. I have 2 other tabs that are working just fine, but when I try to add this third one it is being really buggy.

added:
After continuing to work on the project, it seems that there is an elusive template running about. I have now hit rock bottom and have deleted the grid view and now starting over. When I have not bounded anything to the grid view I go in to relations and it still says there is a child template of "Material List", BUT THERE SHOULDN'T BE. The templates collection is blank. How do I get rid of this?

added:
I ctrl + f for "MaterialList" to find that it was still embedded in code behind. I got rid of it and now it works, but there is a new problem.
I have a composite key on the table.

Reject Report:
Primary Keys: Reject_ID and Revision

Parts List
References: FK_REJECT_ID AND FK_REVISION

When I add to the parent and child column names of the relation, just the first key "REJECT_ID" AND "FK_REJECT_ID" it works, but pulls back materials for all revisions if there is more than one. Then, if I add the second set of column names it does not return anything. It actually doesn't even show the tab.

Do I need to do something different when messing with composite keys?

Thanks,
Chuck

Hi,

I have a LookupEntity type with a property Description of type MultilingualDescription - see snippet below. I want to use a list of LookupEntities as DataSource of a GridViewComboBoxColumn. The ValueMember should be the Code and the DisplayMember should be LookupEntity.Description.French

How can I achieve this?


Thanks in advance.

I have a RadTreeView bound to a bindinglist, which has code that is executed on SelectedNodeChanged.  The code fills a grid.  For some nodes, when they are selected, SelectedNodeChanged fires for that node, then two others afterward.  What, other than the user clicking on the node, would fire SelectedNodeChanged?  This doesn't happen for all the nodes, and I don't know what could be different about them.  Thanks!

I have a number of configurations in my application that I would like to enter into a treeview.  For instance:

Parent Configs
---{CheckBox} Allow posting:
------ Posting Account: {ComboBox}
---{CheckBox} Post Payments
------ Payment Number: {TextBox}
------ Payment Account: {ComboBox}

Something like the above, Perhaps even add descriptions to each node.  An example of someone who already does this IntegralUI TreeView for .NET WinForms I think it would be a great feature for your product.

That being said, is there any way to do this, even through code?  Even if the ComboBox or TextBox needed to be their own node, I could put them as a child under the description, that's no big deal.  Any thoughts, or ideas?

Hi Telerik Team,

All the examples that I have found online is binding to TreeView with Datasets. Is it possible to bind to treeview with business objects? If so would you mind providing me some code snippets and examples?

Thank you all for input.

Hi,
Im evaluating the telerik treeview component and trying to get it to work with a dataset, ParentIDMember and Relation but i just can't get it to work with both ParentIDMember and relations between multiple tables in the dataset. One at a time works.

The dataset contains two tables.

One folders table with folderid, parentfolderid and foldername columns. This table work find to bind with the treeview using the ParentIDMember to get a hierarchy treeview of the folders.

The second table contains data that should be found in a specific folderid with two columns of FolderID and ObjectName. The treeview shows the relational data if i do not use the ParentIDMember property on the treeview, but then i dont get the hierarchy of the folders in the view and the ObjectName doesnt show up at all when using the ParentIDMember property.

Should this work or do i have to work with ParentIDMember OR relations between tables to show hierarchy treeview of data?
