Do you had some example for me using this "best" pattern to start the GUI of my new app?

Desert Theme is lost

Hi,

I can not find the Desert Theme at design time on my radcontrols after upgrading to Q3. If I try to apply this theme via programming, then no theme is applied.

Any ideas?

Thanks & regards,

Disabling autoselect when there is only one row

Hi,

I've a problem with the Autofilter in the MultiColumn ComboBox:

If AutoFilter is turned on, and I type some numbers in the CB and if there is only one value in the Combo Box which matches with the text we type it is automatically getting selected.

Is there a way to disable this function because extra numbers are getting added after the autoselect.

For eg if I m typing the value 990113 in the text area of CB,and there is only one value in the Combobox which starts with 9901,then
if we just type 9901 the value 990113 will get automaticaly selected .So when we try to type 990113 ,
after we type 1 it will automaticaly select 990113 and it will also add 13 which we type and the value will be like this 99011313.

Please advise how to workaround these problems.

Thanks

Existing Windows Forms User Control into docking window

Hi,

I have the following scenario.

I have windows forms user control (written Framework 4, VS 2010, C#) and I need that user control to be dockable so users can move it from the main application window to the second monitor to be visible while main form is visible as well.

So I need to have a sample code or better a simple demo project in C#/VS 2010 that demoes how it can be achieved.

Refresh GridView on new row added

I want to refresh the gridview on first form(form1) when form2 is closed.

How can I do this?

Bind Multiple DropDowLists to Same DataSource

I have a situation where I have a list of topics (stored in a datatable) that I would like to tie to multiple dropdownlists on separate tabs of my form. In doing so, it appears that when I change the value of one, it changes the value of the other, triggering all of the index_changed events and every other repercussion that goes along with that (default values, etc.).

Is there a way to tie this same datatable to multiple dropdownlists without having the selections mirror one another? I realize that I could loop over the table and add items but I would rather not go down that road. The code that I am using to bind is below. Any help would be appreciated.

With ddSMTaskType
.BeginUpdate()
.ValueMember = dtTaskType.Columns(0).ColumnName
.DisplayMember = .ValueMember
.DataSource = dtTaskType
.SelectedValue = "Meeting"
.EndUpdate()
End With

With ddSTTaskType
.BeginUpdate()
.ValueMember = dtTaskType.Columns(0).ColumnName
.DisplayMember = .ValueMember
.DataSource = dtTaskType
.SelectedIndex = 0
.EndUpdate()
End With

RadMultiColumnComboBox editor auto resize problem

When the user resizes a form and the RadMultiColumnComboBox is stretched to a larger size, the editor does not seem to stretch with it like you would expect. So when you click the down arrow, the editor is much smaller than the width of the control. Is there a property I can set?

Multiple RadControls entries in the Toolbox

We have identified several occurrences of multiple/duplicated ToolBox items existing in the Visual Studio Toolbox. Unfortunately these seem to stem from a glitch in Visual Studio, which was still not reproduced reliably so that we can fix it, or ask Microsoft for a fix.

Below are the different kinds of occurrences and their possible fixes:

Duplicate Toolbox items, remaining two entries per control:
- this could be a result of having parallel RadControls installations, which is the correct behavior (Visual Studio 2008 only)
- this could be the result of an improper deregistration of an older RadControls distribution, followed by the registration of the newer one. Usually either of the two approaches below helps fixing the problem:
  - Close Visual Studio instances, start Windows Explorer, navigate to %localappdata%\Microsoft\VisualStudio\10.0 and delete the *.tbd files
  - Right-click the Toolbox inside Visual Studio and click Reset
Multiple entries per control, number increasing with each start of the IDE: this is the worst scenario we have come across. All the registry entries and files on the customer machine seemed fine in this case. The only fix we were able to apply was a complete uninstall of RadControls and Visual Studio 2010, followed by a clean install of the IDE and the RadControls.

Kind regards,

Programmatically setting CurrentRow with only 1 row in grid

When I have only 1 result in a grid, and I try to programmatically select that row it does not set the SelectedRows or associated properties.

var newrow = CurrentOrdersGridView.Rows.Where(o => ((TDOC2.UIFunctions.ORDER.OrderSearchResult)o.DataBoundItem).PRI == oldpri).FirstOrDefault();

if (newrow != null)

{

CurrentOrdersGridView.CurrentRow = newrow;

}

I select the newrow from the gridview's Rows collection. I see that I have a valid newrow. CurrentRow is null before I set it to newrow, and gets set properly, but the SelectionChanged event doesn't fire. And if you look at SelectedRows it has a count of 0, even though CurrentRow is properly set. If I have 2 or more records it works fine. It seems to me that the first row in Rows is considered selected by default, and so it's not registering a change. But at the very least SelectedRows should be set when I assign newrow.
