Questions on UI for WinForms Forum

Good afternoon.
I have a problem with RadPanelBar. I use VB Express 2008.
I create a new WinForm project and add a RadPanelBar control. Dock = True, GroupStyle = ExplorerBarStyle.
This is the code:

Imports Telerik.WinControls.UI

Public Class Form1

Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

Dim rpbge As RadPanelBarGroupElement

For i As Integer = 0 To 10

rpbge = New RadPanelBarGroupElement

rpbge.Caption = "Group" & i

rpbge.EnableHostControlMode = True

RadPanelBar1.Items.Add(rpbge)

Next

Dim rlc As New RadListControl

rlc.Height = 2

rlc.Width = rpbge.ContentPanel.ClientSize.Width

rlc.Anchor = AnchorStyles.Left Or AnchorStyles.Right Or AnchorStyles.Top

rpbge.ContentPanel.Controls.Add(rlc)

rpbge.Expanded = True

End Sub

End Class

Now:
- Run the project and scroll down with the vertical scroll bar.
- Collapse and Expand the last group (Group10).
- Now try to scroll down again with the vertical scroll bar and you'll see the flicker.
Is there any solution?
Thank you in advance.

ListControl problem with scrolling and styled Items

Hi.

I have a "little" problem with the ListControl.
I am trying to do a little Chat thingy.. and facing a Problem when the items are formated with Styles (Font, Size, Bold...).

In my Test Application you will see some controls.
1.) ListControl that stores the written messages
2.) A TextBox to input the desired Text message
3.) 2 Buttons with the text 1 and 20 - The 20 Button just calls the 1 button 20 times
    The 1 Button, inserts 3 Items into the ListControl
        1st a HeaderItem with the UserName and the DateTime
        2nd a TextItem with the given Text
        3rd a FooterItem to get a space between Messages
4.) An indicator for the Items.Count Value of the ListControl

So now the Problems i have after i have added some Messages to the ListControl and do some scrolling at some Point you will notice 3 Errors.
1.) The last Item doesnt get selected (not Highlighted with the Orange Color)
2.) The scrolling doesnt work. The Scrollelement moves but the ListControl seems like frozen.
3.) No new Items get displayed, tough it works - Item Counter goes still up.

Another Problem is that when i call the 20 Buttons at first after the form loads, the last item doesnt get selected. But this isnt really an issue that i am facing in reall application, because this button only exists in this test application so that you can add items faster, since you need some. (Second time hitting this button selects list item fine, only doesnt work when hitting it at first)

Hope you guys can help me fix those problems, already tried some LayoutUpdates but no luck till now. :(

And a side Note Question, is there a way to change the HighLight MouseOver and the Select Color?

Filtering RadGridView with IQueryable as datasource

Hi,

I have a radgridview which has an IQueryable as datasource. When attempting to filter the radgridview using filter descriptors the fiter descriptors are shown on the grid. But the fields are not filtered. I have an idea this has something to do with the binding?

The IQueryable is generated in the DAL and returned to the BL which in turn returns it to the WinForm. There is no way to directly access the database as we can only work on the Winform.

Is it possible to filter the radgridview when it is using an untyped IQueryable as datasource?

radGridView1.DataSource = BusinessObject.getAll(); //Returns IQueryable

//Setting filter descriptors

FilterDescriptor filter = new FilterDescriptor();

filter.Operator = FilterOperator.IsEqualTo;

filter.PropertyName = "Username"t;

filter.Value = "Bob";

filter.IsFilterEditor = true;

this.radGridView1.MasterTemplate.EnableCustomFiltering = true;

this.radGridView1.MasterTemplate.EnableFiltering = true;

this.radGridView1.FilterDescriptors.Clear();

this.radGridView1.FilterDescriptors.Add(filter);

radGridView1.ShowFilteringRow = true;

RadMaskedEditBox simple decimal

Hey at Telerik

I would like to know how i can set the RadMaskedEditBox to accept only a decimal number.

I need the RadMaskedEditBox for coordinates and cannot limit the box to a specific number og digits before the seperator or after.

The closest i can get is by setting the MaskType of the RadMaskedEditBox to 'Numeric' and the Mask to 'n'.

As i see it 'n' and 'n2' gives the same result. isn't 'n' supposed to not limit the input.

Sincerly

looking for help on moving row from a grid on a form to another grid on another form scenerio...see message for more detail

Hello,
I am trying to acheive the following scenerio and was hoping i could get some guidance or even a sample. Here is the scenerio.

I have a form with 2 raddocks on it. I am loading my forms into the left raddock which is on the left. one of the forms is a searching feature for searching inventory. on the second dock i am loading a sale order form. when a user does a search for inventory i am wanting them to be able to drag a row from the search results (gridview) to an identical gridview on the other form(sale order form). Right now i have a collection on the order form which stores which inventory items it has. i then bind the grid view to the collection to show current inventory that belongs to the sales order. ideally what i would like to happen is a user selects an item (row) from the gridview on form1 and can drag it over to the other form at which time i populate the collection on that form and bind its gridview to that collection?
is it possible to drag and drop a row from a grid on one form to a grid on another form if so...how can i accomplish this?

Thanks,
Joshua Gates

Editable Pivot Grid

Does something like this exist?

I want to transpose my normalized data into a pivot view, but also have that pivotview be editable and then have those edits update the backend normalized table that it came from. Is this a feautre, or do I have to write my own enumaration class, stored procedures, etc. to do this for me?

Thanks,
~patrick
