Add New RowPosition Bottom causes UserAddedRow event not to fire...

I think I found a bug in the latest realease 2011.3.11.1219 that causes the UserAddedRow event not to fire.. Found this after upgrading a large project and critical events that occur after a user completes adding a new row no longer fired.

This is not confined to my project as it can be reproduced easily in new projects.

To reproduce you just need a bound grid with the new row position set to bottom, then hook the UserAddingRow event. The event will never fire. Change the new row position back to default (Top) and the event fires.

This doesn't appear to affect any other events including the UserAddingRow event, only UserAddedRow.

// Change new row position to bottom

this.radGridView1.AddNewRowPosition = SystemRowPosition.Bottom;

// Add an event for UserAddedRow

this.radGridView1.UserAddedRow += new GridViewRowEventHandler(radGridView1_UserAddedRow);

// Event will not fire

void radGridView1_UserAddedRow(object sender, GridViewRowEventArgs e)

{

throw new NotImplementedException();

}

Need example for data-binding to a chart with multiple series

The guide below shows an example for one series (in the example, one list of Products):
http://www.telerik.com/help/winforms/chart-building-radcharts-data-binding-radchart-to-a-generic-list-of-objects.html

How would I data-bind multiple series to a chart (in the example, more than one list of Products)?

Timeline Footer

Hello,

I was wondering if it was possible to have a footer at the bottom of the timeline view. For example, it could show the number of appointments in that day or month.

Filtering on Guid columns

Hi Everyone!

I started using the RadGridView. The grid is populated by a DataTable containing string, boolean and guid values for the different rows.

I mapped the guid columns to GridViewComboBoxColumns whose DataSources are DataTables containing the Description for the Guids (see code).

DataTable data = DbTools.GetExistingFawisGroups();

DataTable clGroups = DbTools.GetBBlockGroups();

DataTable clCategories = DbTools.GetBBlockCategories();

GridViewComboBoxColumn colGroup = new GridViewComboBoxColumn();

colGroup.Name = "columnGroupId";

colGroup.HeaderText = "Gruppe";

colGroup.FieldName = "bBlockGroupId";

colGroup.ValueMember = "id";

colGroup.DisplayMember = "descript";

colGroup.DataSource = clGroups;

this.radGridView.Columns.Add(colGroup);

GridViewComboBoxColumn colCat = new GridViewComboBoxColumn();

colCat.Name = "columnCategoryId";

colCat.HeaderText = "Kategorie";

colCat.FieldName = "bBlockCategoryId";

colCat.ValueMember = "id";

colCat.DisplayMember = "descript";

colCat.DataSource = clCategories ;

this.radGridView.Columns.Add(colCat);

this.radGridView.DataSource = this.data;

this.data.AcceptChanges();

Now filtering (GridView standard filters) for all columns except the mapped guid columns is working fine. When i click on the filter icon in the column headers of the guid columns, i see the descriptions representing the guids and can select them. But by clicking ok i get the following exeption:

The exeption "Missing operator

before a operand" always contains a part of the guid, in this case it's just the "a", but it's always different an definitly a part of the guid.

What can i do to make filtering work for all my columns in the grid view? The posting (http://www.telerik.com/community/forums/winforms/gridview/cannot-use-a-guid-as-a-valuemember-with-filtering-on-radgridview.aspx) seems to point to the same problem, but doesn't solve my problem because by appling the described solution none of my filterings are working any more.

Kind Regards,
Michael

Hide MDIButton of RadRibbonBar in RadRibbonForm

Hi,

I need to hide the MDIButtons (Minimize, Restore/Maximize, Close buttons) of RadRibbonBar in RadRibbonForm. I tried using this code (radRibbonBar1.RibbonBarElement.MDIbutton.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;) but it always shows whenever I resize or maximize the form or show another child form. I attached a screen shot.

Many thanks,

Ian

Question about navigating root element tree

Hi,

I would like to programmatically get to some of the hidden properties that I can see in the Element Hierarchy Editor, but don't see an obvious way to do so.

For instance, a RadButton has a root element and then a Fill Primitive, Layout, Focus, Border, etc. Drop down lists have other goodies in there. How does one get there in c#?

Is it something like this, but then casting it to something else? For instance..
(FillPrimitive) btnFoo.RootElement.children[0]

It would be really nice to know how to navigate the tree because there are a lot of properties that we could take advantage of.
Thanks.
Jason
