Custom Property in Rad State Editor

We would like to assign our own property to a rad UI control that we could then examine in the Rad State Editor. For instance we could have a property added to the RadTextBox that could be called something like errorState. We could then set errorState to true at either design time or run time to indicate the error state of the text box. The controls default theme would then examine this property in a custom state created with the Rad State Editor in the Visual Style Builder. This would then dynamically apply the proper visual styles to the textbox for the custom error state. This would allow us to encapsulate all visual elements of our application into a single master theme.

We have a need for a custom property on a textbox. I have found how to create a custom RadProperty, but I do not know how to attach it to all of the textboxes in the application. Is there a tutorial or something that we could follow for this functionality?

Thanks

RadPanel and Validation

Hi,

I moved my controls from a standard panel onto a RadPanel and noticed, that Form.Validate() was no longer validating my controls on the RadPanel.

The reason for this is, that RadPanel.CausesValidation is false by default and not visible in properties window. Why this?

Regards
Martin

Loading RadPanelBar Groups and Elements from a Database

Hi,
I'm new to RadControls and am having fun using the different controls. I am trying to load groups and elements in a RadPanelBar based on a group table and an items table in my database. If I can do that my employers will gladly buy the full suite. I looked at the help and I can build up the groups programmatically. Is there a tutorial or an easier way to do this? I can build it up using datasources, but just wondered. I'm using SQL Server, but the help files show an example using Access and OLEDBConnection.

Thanks a lot.

Disable Popup Fast Navigation window

I would like to disable the fast navigation popup that appears when clicking on the calendar's "title" (Month-Year). When clicking there, a popup appears allowing the user to select a different Month-Year. I would like to handle this event with a different popup. I have been able to tie into the same mouse down event to create my own popup window, however the telerik fast navigation window still pops up. Is there a way to disable this so that I can handle the event myself and popup my own fast navigation type of window?

I would like to keep the fast nvaigation arrows and header in place, just replace the popup that gets displayed when clicking on the Month-Year text.

Thank you.

William

Hierarchical GridView - winform bind in code

Okay, I know I'm missing something here. I'm using the latest version of Rad for WinForms (Q1 2008) and I'm trying to populate a RadGridView using code only (not the BindingSource control). Can you tell me why this code isn't working?

private void PopulateGrid()
{
DataSet ds = GetMasterDetail();
radGridView1.DataSource = ds;
}

private DataSet GetMasterDetail()
{
DataTable master = Clients.GetMasterList();
master.TableName = "Clients";
DataTable child = Orders.GetChildList();
child.TableName = "Orders";

DataSet ds = new DataSet();
ds.Tables.Add(master.Copy());
ds.Tables.Add(child.Copy());

DataRelation relationship = new DataRelation("MasterDetail", ds.Tables["Clients"].Columns["ClientID"], ds.Tables["Orders"].Columns["ClientID"]);
ds.Relations.Add(relationship);

return ds;
}
