Hi.
I have an UltraCombo that is assigned to a grid cell EditorControl. Everything works as planned, except for one thing: The UltraCombo grid column does not auto size to the drop down.
I have tried setting the relevant AutoSize on the column and AutoFitStyle on the control without luck.
What am I missing here?
Best regards,
Goran
Hi Goran,
I don't understand what you are asking. Why would the column in the grid size itself to the dropdown? That does not make sense. The dropdown shows multiple columns and there is no relation between those columns and their widths and the grid column width.
The UltraCombo shows ONE column as I want to display it as 'normal' drop down. This column should span the entire width of the UltraCombo, otherwise it looks strange (when selecting items, the selection is cropped at the column border). No matter what I do, I cant accomplish this.
So I am not trying to resize the main grid column, I am trying to resize the drop down grid column.
Any suggestions?
Hi,
Okay... so what are you trying to autosize the column to? AutoSize means setting the width of the column based on the contents so you make sure all of the text in the column is visible to the user with no scrollbars. Is that what you want?
Or are you trying to make the column in the dropdown (and thus the dropdown itself) the same width as the grid column it's in?
Also... may I ask why you are using an UltraCombo? There are easier ways to provide a list in a grid cell.
Hm... are you saying that the dropdown is showing extra space in addition to the width of the column?
The default behavior of the combo is to size the DropDown to the columns automatically. So if you are getting extra space it's because you changed something.Like maybe you are setting the DropDownWidth property on the Combo. That's not what you need in this case, though. What you should do, instead, is change the width of the Column in the dropdown and let the dropdown itself size to the column - which it will do automatically unless you also changed the AutoSizeMode.
Yes, exactly. I need for the drop down to auto size to the container cell, and I need the drop down column to auto sixe to the drop down width.
Trying with the BeforeCellListDropDown now, will report on result.
Got it to work! Now if I only could find a place to read the width of the drop down button, I would be all set... ;-)

Private Sub productTypesGroupsGrid_BeforeCellListDropDown(ByVal sender As Object, ByVal e As Infragistics.Win.UltraWinGrid.CancelableCellEventArgs) Handles productTypesGroupsGrid.BeforeCellListDropDown Dim tmpDD As Ultra Dim btnWidth As Integer = 20 tmpDD = CType(e.Cell.EditorControlResolved, UltraCombo) If tmpDD IsNot Nothing Then tmpDD.DisplayLayout.Bands(0).Columns("Name").Width = e.Cell.Column.CellSizeResolved.Width - btnWidth End If End Sub
CType is "Convert to type". It's just like casting in C#.
So:
editorElem = CType(buttonElem.ChildElements(0), EditorWithComboUIElement)
is the same as:
editorElem = (EditorWithComboUIElement)buttonElem.ChildElements(0);
Thanks for the code example! I had to convert to C# though, as this project is using it (see below).
Also, I didn't know how to convert your Ctype methods above, so I just used a foreach loop, i'm sure there is something more elegant, but its probably doing the same thing anyway.
also, my situation was a little different, we put this code in all of our drop down controls (in grids and on forms) on the "BeforeDropDown" event, so we really don't have a handle to the UltraGrid, but the UIElement was available for us to use.
Infragistics.Win.EditorWithComboUIElement editorElement = null; Infragistics.Win.EditorWithComboDropDownButtonUIElement comboElement = null; Infragistics.Win.EditorWithTextUIElement text = null; try { foreach (var element in UIElement.ChildElements) { if (element is Infragistics.Win.EditorWithComboUIElement) editorElement = (Infragistics.Win.EditorWithComboUIElement)element; } if (editorElement != null) { foreach (var element in editorElement.ChildElements) { if (element is Infragistics.Win.EditorWithComboDropDownButtonUIElement) comboElement = (Infragistics.Win.EditorWithComboDropDownButtonUIElement)element; if (element is Infragistics.Win.EditorWithTextUIElement) text = (Infragistics.Win.EditorWithTextUIElement)element; } if (comboElement != null) buttonWidth = comboElement.Rect.Width; } } catch (Exception) { }
Here is a small code example of how I did it:
Private Sub myGrid_BeforeCellListDropDown(ByVal sender As Object, _ ByVal e As CancelableCellEventArgs) _ Handles myGrid.BeforeCellListDropDown
Dim tmpDD As StandardDropDown 'This is actually an UltraComboDim btnWidth As Integer = 20Dim buttonElem As UIElementDim editorElem As EditorWithComboUIElementDim comboElem As EditorWithComboDropDownButtonUIElement'Get ref to dropdowntmpDD = CType(e.Cell.EditorComponentResolved, StandardDropDown) Try 'Get UIElement from cell buttonElem = e.Cell.GetUIElement() 'Get main editor element editorElem = CType(buttonElem.ChildElements(0), EditorWithComboUIElement) 'Get actual editor (UltraCombo) element
comboElem = CType(editorElem.ChildElements(0), EditorWithComboDropDownButtonUIElement) 'Set button width to with of editor button width btnWidth = comboElem.Rect.Width + DROPDOWNBUTTON_WIDTH_COMP 'const to adjust width, it misses by a few pixels for some reason Catch Throw End Try If tmpDD IsNot Nothing Then 'Adjust with of grid column in drop down tmpDD.DisplayLayout.Bands(0).Columns("Name").Width = e.Cell.Column.CellSizeResolved.Width - btnWidth End If
End Sub
Mike,
could you provide a small code example for what you described above? I too need to get the drop down button widths.
it seems to be different for grids and controls so if I can grab the actual value that would be preferred.
Thanks for the tip. I ended up using the ChildElements collection and drill down to the correct element. Then I used the Rect property to get the width. Works great. Thanks again!
