Questions on UI for WinForms Forum

Hi,
I am developing a winforms app using dock with a single tool window, currently I have tool window located in the top. I really want it to display as it would if it were in the middle but for styling reasons I prefer a tool window to a document window.

So the result right now is an odd space below the tool window and the splitter that divides the tool window from the odd blue space. is there any way to put a tool window in the center, or to make the splitter disappear and lock the tool window so if the user alters the size of the form the tool window will grow in size as well as opposed to the blue space growing as well. I have attached a picture so you can see the blue space separator/splitter I am talking about.
thank you in advance for your help.

Sort a column with value of other column

Hello,

I have a gridview containing a file explorer. For the column filesize I have a hidden column with the filesize in bytes. The I have another column with the size formatted to a string containing 8,25 KB, ...

When the user wants to sort the data by the filesize column, I have to sort dynamicly on the hidden column instead of the filesize column.

Is there a way of doing this?

Tnx!

Hierarchy control does not show up

I have a hierarchical RadGridView that I am putting a RadPanel with a user control into during cell formatting. When I expand the row to look at the control all I see is the AddNewRow Pane. If I set AllowAddNewRow to false the row never expands. Below is the code I am using to do this. Any help I could get with this would be great.

private void TemplateRelations()

{

GridViewTemplate template = new GridViewTemplate();

template.Caption = "Tracking Info";

template.DataSource = trackingInfos;

gvTrackingInfo.Templates.Add(template);

template.AllowRowResize = false;

template.ShowColumnHeaders = false;

template.ShowRowHeaderColumn = false;

template.Columns[0].Width = 800;

template.Rows[0].Height = 500;

for (int i = 1; i < template.Columns.Count; i++)

{

template.Columns[i].IsVisible = false;

}

GridViewRelation relation = new GridViewRelation(this.gvTrackingInfo.MasterTemplate, template);

relation.ParentColumnNames.Add("TrackingNumber");

relation.ChildColumnNames.Add("TrackingNumber");

this.gvTrackingInfo.Relations.Add(relation);

}

private void gvTrackingInfo_CellFormatting(object sender, CellFormattingEventArgs e)

{

TabContainer tabContainer = new TabContainer();

GridViewDataColumn column = e.CellElement.ColumnInfo as GridViewDataColumn;

if (column != null && column.OwnerTemplate.Caption == "Tracking Info")

{

RadPanel panel = new RadPanel();

tabContainer.Height = 500;

tabContainer.Width = 800;

panel.Controls.Add(tabContainer);

panel.TextAlignment = ContentAlignment.MiddleCenter;

e.Row.Height = 500;

e.Column.Width = 800;

e.CellElement.Children.Add(new RadHostItem(panel));

}

RadGridView Cell Location

I am trying to use RadGridView.RowPain. I need an extra header row to show that the columns are categorized:

e.g.

[-------- Category A --------][-------- Cat B --------][-------- Category C --------]

[--- Col 1 ---][--- Col 2 ---][------- Col 3 --------][--- Col 4 ---][--- Col 5 ---]

This should be relatively easy, except I don't know how to find out the cell locations for the column headers. Because my cells cannot be moved, I tried adding up the cell widths, I had some success - except when use the horizontal scroll bar.

Please can someone explain how to get the cell locations.

Thanks

Force Validation When Saving

Hello:

Our controls do not validate until after the user tabs off, which is the default for binding (OnValidating). However, in the case where the use clicks a save button, validation is taking place after the save event fires. This leads to situations where the changes aren't saved and the user closes the form, losing their changes.

In Windows Forms, you could call ValidateChildren to force the controls to bind to the underlying data object. This doesn't appear to work with Telerik controls.

Is there a way to force changes to commit to the data object before the save takes place? I don't want to change the binding DataSourceUpdateMode to OnPropertyChanged.

Thanks,
Travis Parks

Customize filtering row

Hi there guys

I'm trying to customize the filtering row in a Winform Telerik Grid. What I want is to hide the Filter Icon and only show the text boxes. When a user enteres text in the text box it should apply the "Contains" filter on the column.

I have been using Telerik ASP Net. Radgrid quite a lot and could set the "ShowFilterIcon=false" and on the gridboundcolumn and "AutoPostBackOnFilter=true" to get the desired functionality.

Any hints?
