How can i filter all the columns/rows in an hierarchical grid at the same time?
The GridView includes 2 tables, AccountName as Master and Contacts as detail. At runtime the GridView shows only the AccountName Column. Now i want to be able to search either an AccountName or a Contact by entering the search criterias in only one field.

Thanks in advance

Complex Grid - Custom Combos per row & more

Hi,

I've got a bit of a problem I'm thinking the rad grid might be able to help out with, but I'm really not sure how to tackle this at all.

I've got a UI that has 10 fields on it, each one is a combo box. They are all linked to an underlying business object, and changing one will repopulate all the others down the line with information based on the selection.

What I'm wondering is - how can I implement this with the Rad Grid? Each row is a business object, with each combo being linked to a property on that object, and each property, when updated, also updates the list of the subsequent properties.

Second to this, I want to be able to add a grouping to the grid - I want to have a field linked to that group, so that if the user adds a new record in the grid under a group, the group field is also filled in.

How would I start figuring out how to do this?

thanks,

GridView

[Solved] Rad Ribbon Bar causes VB to crash

I'm using the RadRibbonBar with VB 2008.net express edition. I've followed the extra steps to get the ribbon bar to appear in the toolbox and everything seems to be OK. However, recently I find that when I create a new project the ribbon bar works fine until I save the project. Then the application won't start - nothing has changed since the last test other than saving the project. I've tried this out several times, changing different things, and have shown fairly conclusively that it is the saving of the project that causes the problem.

My test case was to create a new project, add the ribbon bar to the form, run the program. All fine. Save the project, run the program. Failed. All default names were left alone, no changes were made to the ribbon bar or the form.

This is the error that I get:

InvalidOperationException was unhandled

An error occurred creating the form. See Exception.InnerException for details. The error is: That assembly does not allow partially trusted callers.

What can I do to fix this? Any suggestions greatfully received.

Thanks,
Martin.

Standard control properties

A quick question about standard control properties;

I have just started using the Winforms control set and started throwing some controls onto the forms expecting to have little problem when swapping out standard controls (buttons, check boxes) etc. I was surprised to find that the checkbox doesn't have a checked property?? Obviously I should be using IsChecked, but why the deviation from having the standard properties. I assumed that I should be able to simply swap out the basic UI controls without issue. Am I missing something very obvious here??

Thanks in advance.

SortChanging

The SortChanging-Event does create an wrong handler:

It should be (original documentation):
Private Sub radGridView1_SortChanging(ByVal sender As Object, ByVal e As SortChangingEventArgs)

It is (my project):
Private Sub rad_grid_SortChanging(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.GridViewCollectionChangingEventArgs) Handles rad_grid.SortChanging

ergo, there no methods like e.NewSortExpression, etc.

I use the Version 6.0.2!

regards
Michael

Border formatting problem on scroll

I have a winforms application correctly displaying data from a dataset.

When a user double clicks on a row it opens a document associated with that row - I want the row to then be highlighted (ie create a border around it) so that the user knows they have viewed that item.

the code i'm using for this is:

dg2.Rows(dg2.SelectedRows(0).ViewInfo.CurrentIndex).VisualElement.BorderColor = Color.Blue
        dg2.Rows(dg2.SelectedRows(0).ViewInfo.CurrentIndex).VisualElement.BorderColor = Color.Blue
        dg2.Rows(dg2.SelectedRows(0).ViewInfo.CurrentIndex).VisualElement.BorderBoxStyle = Telerik.WinControls.BorderBoxStyle.OuterInnerBorders
        dg2.Rows(dg2.SelectedRows(0).ViewInfo.CurrentIndex).VisualElement.DrawBorder = True

this works fine - until i use the scroll bars - the highlights stay in the same place visually - but this now highlights the wrong items.

Help please......
