I have a list of items shown in a GridView. After Initialization I only want to show some, and not all of these Items.
I do this through a function call with the components with the Items I want shown.
My problem is how to hide the Items that I don't want shown. I can't use filtering, because it is impossible to construct a useful filtering string that singles out the objects that I have sent.
I have tried to retrieve all the GridViewRowInfo, setting their IsVisible property to false, then setting IsVisible to true to the ones I want shown. But all Views are still shown in the GridView component.
My Grid is hierarchic, has this anything to do with my items remaining visible?

Hi All,
Is there a way to set the tab when the color dialog opens? It currently defaults to "Professional", but I would like it to default to "Basic".
Thanks in advance for the help!

Hi,
I was playing around with RadLabel.
I found a difference to Forms.Label which is a thing I'm hardly missing!
When I place a label - regardless of it's height - I can (with Forms.Label) drag it so that the text is alligned with the next control.
It shows a magenta line when alligned properly.
But RadLabel doesn't show this line.
Am I doing something wrong - or is this feature really missing?
The same problem with RadCombo -- I use a Forms.Label with a Forms.Combobox -- and get the magenta line.
I do Forms.Label with RadCombo - no such line.
Regards
Manfred

Hi,
I am trying to show the font list in the combo box in the ribbon bar. Is that any possible to show the "sample" text in the combo box itself? So the user can preview the font before they selecting it.
Please advice.

Hi,
I am setting the BackColor of a RadTextBox control at runtime. There are some discrepancies between what the documentation says, what the recommended approach is in the forums, and what actually seems to work.
The documentation:
ms-help://telerik.winforms.5.0/telerik.winforms.raduielements/RadTextBoxProgramming.html
The fourms:

When adding a new row (in line editing), the GridViewNewRowInfo.DataBoundItem is null even though it is bound to the underlying object.
Here's my situation: I'm binding a BindingList of objects to the grid's data source. I'm implementing an MVP pattern where the Presenter listens to the binding list's AddingNew event and initializes the new object. Prior to Q1 2008 beta, the initialization made in AddingNew was not reflected in the grid's new row (this seems to be fixed in Q1 08 beta).
I am also implementing cascading combo boxes (Country selection drives items in the State column). The Presenter listens to ListChanged events and computes the available States when the object's Country changes. The filtered list of States is added to the object (presentation model). In RadGridView.CellBeginEdit, the view modifies the RadComboBoxEditor, reseting the State list source to the new filtered list in the presentation model. This works for existing rows, but breaks for new rows since the new row's DataBoundItem is null.

Now that the rows collection includes only data rows, how do I get the child data rows for a GridViewGroupRowInfo? I'm in the SelectedRow event after a group row was selected by the user. I need to get information from the data rows that makes up the group. The rows collection is always empty. This one is BIG.

Hi, how can I change the style on alternate row? I see another post with same question, and you told to do it:
private void radGridView1_RowFormatting(object sender, RowFormattingEventArgs e)
{
if (e.RowElement.IsOdd)
{
if (!e.RowElement.IsCurrent)
{
e.RowElement.BackColor = Color.Beige;
}
else
{
e.RowElement.BackColor = Color.LightBlue;
}
}
}
but when you scroll, you loose the style.

Since this release completely breaks backward compatibility, is there anything I can refer to for tips/techniques for upgrading? Some of the items have been obsoleted and therefore tell me the replacement method. A few others I've been able to figure out through experimentation or by looking at the examples. There are some where the feature has been commented out in the example (see AutoCompleteMode and DropDownStyle of a grid combobox column) and it's not obvious how that functionality has been replaced. I would love a list of breaking changes and the replacement way to do the same thing.
Thanks.
Thanks.
