DropDown Scroll Broken

The latest release - Q3 2014 - has broken the dropdown control unless we are overlooking something.

Create a RadForm, drop a RadDropDownList control on the form.

Add _8_ items (enough so it goes beyond what shows in the list when you click the drop down) to the dropdown list.

Run the program.

Click the dropdown and you see items 1 through 6, now try to scroll to see items 7 and 8. The dropdown immediately closes.

Unless we are overlooking something this seems fairly serious as it more or less breaks any app that uses the simplest of dropdown.

Grid not refreshing/updating properly when changing cells

Hi,
I have a main grid on a winform.
When adding rows to it(ONCE) i use a background thread that creates a 2nd grid programmaticlly and adds the rows to it. when it finishes, the main thread calls MainGrid.AddRange(backgroundgrid.rows.toArray()).
It gets the info right, but the values aren't refreshed.
It seems to only refresh when the UNSEEN rows are shown:
When i scroll down the values that weren't shown(below) are correct, when scroll back up it refreshed the grid also.

How do i fix this situation?
NO DB no Dataset no datatable.

some problems about image combobox in radgridview

Hi,
I have a radgridview and it has 5 columns and 36 rows
(1 and 2 columns are GridViewTextBoxColumn and
4 and 5 columns are GridViewComboBoxColumn)
.I wanna add the images as the combobox's items, so I search and
apply the source base on this example.
http://www.telerik.com/forums/gridviewcomboboxcolumn-that-displays-only-icons-images

When I finished the code and run it, some problems happened.

First, in the first picture,
When the scroll of the table is moved down, some cells not conserned with
image combobox display the images(solid dash line image).
I wanna know how to fix that.

Second, in the second picture, when I open and select the
image of comboBox, some texts are shown as figure.
Although these texts are disappeared if I clicked other place,
but I don't want skip that step. (In upper example source, that has same reaction.)
Can I fit that? If it could, I wanna know how to remove that step.

Third picture is about my source.
Please point out my problem.
And if it is possible, I wanna example source about
successful case of my problems.

Thank you.

Avoid auto sorting in RadGridView

I want to sort the grid only on Header click. In sorting when ever we modify the value of the sorted column the rows get auomatically sorted based on the value.
I just want to avoid this auto sorting during modifying the cell values, it should happen only on header click. Is this possible in RadGridView for win form ?

Rows.AddNew returns null

Hi,

I am using the gridview Q1'14 in unbound mode and with load-on-demand.
Populating the grid and loading the child rows in the RowSourceNeeded Event works fine.

Adding new Rows in the MasterTemplate with Rows.AddNew works as well.

But adding a Row in MasterTemplate.Templates[0].Rows.AddNew always returns null.

Am I forgetting something?

Thanks in advance for a qujick response!

Child GridViewTemplate.Rows.AddNew returns null

Hi,

I am using the GridView in Unbound Mode, and with load-on-demand.
Populating the grid, and loading the children in RowSourceNeeded works fine.

Adding a record in the mastertemplate with Rows.Addnew works as well.
But adding a record to a child level template with grid.MasterTemplate.Templates[0].Rows.AddNew always returns null.

Am I forgetting something?

Thanks in advance for a quick response!

Inputbox

Hi,

I would like to suggest an Inputbox for the Winforms control set. I think if you offer a radmessagebox it would only be normal to include an Inputbox.

Thanks

Bottom border missing in selection

Hi,

Sometimes I'm pedantic when it comes to the appearance of the application.
I have a RadGridView called cGrid with events:

private void cGrid_CellFormatting(object sender, CellFormattingEventArgs e)

{

// simple background

e.CellElement.BackColor = Color.FromArgb(186, 220, 230);

e.CellElement.BackColor2 = e.CellElement.BackColor;

e.CellElement.BackColor3 = e.CellElement.BackColor;

e.CellElement.BackColor4 = e.CellElement.BackColor;

e.CellElement.DrawFill = true;

}

private void cGrid_ViewCellFormatting(object sender, CellFormattingEventArgs e)

{

// border color from background

Color color = e.CellElement.BackColor;

// but if IsCurrent or IsSelected the border color should be red

if (e.CellElement.IsCurrent || e.CellElement.IsSelected)

{

color = Color.Red;

}

// single border for nice looking

e.CellElement.BorderBoxStyle = BorderBoxStyle.SingleBorder;

// solid for using only one color

e.CellElement.BorderGradientStyle = GradientStyles.Solid;

e.CellElement.BorderColor = color;

e.CellElement.DrawBorder = true;

}

And set:

this.cGrid.EnableHotTracking = false;

this.cGrid.HideSelection = true;

this.cGrid.MultiSelect = true;

this.cGrid.SelectionMode = Telerik.WinControls.UI.GridViewSelectionMode.CellSelect;

And now I see by selecting multiple cells (check attachment).
For cells ch last selected row can not see the bottom border.
Do you know a trick to solve this "problem"?
