I have a set of tabbed ToolWindows that are initially hidden when my application starts. When I hover over one of them, and then select to pin the windows, is there a way to specify the width, and/or height, that I want them to be when pinned?

Thanks.

RadGrid Winform Refreshing Datasource

Hi, I recently installed the Telerik Winform and using the RadGrid control. I am working with a database where the values get updated every second and I have to display the updated rows to RadGrid. Before that I was using the standard DataGrid but there was lot of flicking problem on assigning the data source again to refresh it.

RadGrid is better option but I am still facing the same issue with it. I am using background worker control with Async mode queries and on Timer control I am refreshing the data
1. Clearing the dataset
2. RadGrid datasource to Nothing
2. Filling the dataset again,
4.and assigning the data source to RadGrid

All the above process causing the RadGrid to flick, can you please guide me to do this is better way. Example will be appreciated.

Thank you.

New row behavior

Hi,

I want to achieve the same 'new row behavior' as the default windows gridview.
That means that if I edit a cell in the 'new row', the row is also added to the datasource and is a 'real' row instead of a 'new row'. Now this only can be achieved by pressing enter or set the focus to another row.

Best regards

RadButton base.OnClick problem

When I override Onclick on RadButton, the code first finishes the whole onclick method before firing base.OnClick.
For a standard Button, this works fine.
In the example below, the OnClick will first finish completely before the base.OnClick will be executed, but is should not.
How to fix this ?

public class QButton : RadButton
{
protected override void OnClick(EventArgs e)
{
var form = FindForm();
try
{
// set wait cursor
form.Cursor = Cursors.WaitCursor;

// execute base click code
base.OnClick(e);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
finally
{
// set arrow cursor
form.Cursor = Cursors.Default;
}
}
}

Buttons, RadioButton, CheckBox, etc

Listview width with or without vertical scrollbar

I have a RadListView, with a ViewType of Listview, and VerticalScrollBar set to AutoHide. I simply want to get the width of the control including the scrollbar if visible.

I have tried ClientRectangle.Width - it did not take into account the scrollbar.width

So I tried checking the visibility of the scrollbar, if visible then subtract the scrollbar width. Even when the scrollbar is visible, it always comes back as Visible=False.

Is this a bug or am I doing wrong something wrong?

Dim iScroll As Integer = 0

'get scrollbar width if needed

If Me.lvwLoadForms.VerticalScroll.Visible = True Then iScroll = SystemInformation.VerticalScrollBarWidth

'resize items and group widths

With Me.RadListView1

.GroupItemSize = New Size(.Width - iScroll, .GroupItemSize.Height)

.ItemSize = New Size(.Width - .GroupIndent - iScroll, .ItemSize.Height)

End With

ListView

GridView ImageColumn not showing image

Hi,

I've already performed a search here, and I think I'm doing this right, but the fact is that my RadGridView does not show the image.
The only thing that the field shows is "System.Drawing.Bitmap"

'Loading image from file ( path in database )

Dim img As Image = Image.FromFile(Reader("Imagem"))

'Attempt 1

r.Cells(2).Value = img

'Attempt 2

'Writing to a memory stream

Dim ms As New MemoryStream

img.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg)

'passing the bytes to the value field

r.Cells(2).Value = ms.ToArray

'Attempt 3

'Simply loading an image from resources to the value field

r.Cells(2).Value = My.Resources.icon_fantasma_05

I know I'm doing something wrong, I just don't know what. These 3 attempts , are based / copy from examples given on the intermet..
I've attached a image, which shows what I'm getting at the GridView.

Could somebody please help?

Thank you very much !

Add extra column for input below another column in gridviewrelation

Hi,

We use a gridview with a gridviewrelation.

The Case:

We have a list of projects, for each project we have employees working on a specified project.
For each week they have to put amount of hour(s), W1 -2014, etc... (see picture)
We have also a column W1Description2014 etc... we want to add this below the column of W1-2014, etc...

See picture for more information.

This is de code we use to add the grid relation:

Dim MyProjectRelation As New GridViewRelation(MyBase.SearchGrid.MasterTemplate, template)
MyProjectRelation.RelationName = "ProjectRelations"
MyProjectRelation.ParentColumnNames.Add("projectnr")
MyProjectRelation.ChildColumnNames.Add("projectnr")

In telerik screenshot we see difrent styles, but we can't find this issue in code.

Do you have any solution for this issue ?

With friendly regards.
