Hi,

I would like to control the style of a point of the RangeSelector when the AssociatedControl is a ChartView.

There's an example available how to do this on a regular ChartView (at http://www.telerik.com/forums/scatter-points-with-different-color-symbol-and-size), but I can't get this to work on a ChartView in a RangeSelector.

In have tried for example to implement an event with:
RangeSelectorViewElement rangeChartElement = ((RangeSelectorViewElement)this.radRangeSelector1.RangeSelectorElement.AssociatedElement);
rangeChartElement.LabelFormatting += this.rangeChartElement_LabelFormatting;

but it isn't being called (and I made sure ShowLabels = true).

Could you please help me?

Regards,

Peter

Remove filterdescriptor on column

Hi,

I am applying a filter to my grid on a hidden column using a form buttons click event (see code below). When I click the button again I want to remove filtering, but only for that particular column i.e. if filtering is already on another column don't reset all filters...

I've tried using Me.DgvInvoiceData.FilterDescriptors.Remove(filter) but the grid stay the same...

Any ideas?

Dim filter As New FilterDescriptor()
filter.PropertyName = "Custom"
filter.[Operator] = FilterOperator.IsEqualTo
filter.Value = "Yes"
filter.IsFilterEditor = True

If btnCustom.Text = "Show Only Custom Lines" Then

Me.DgvInvoiceData.FilterDescriptors.Add(filter)
btnCustom.Text = "Show All Lines Including Custom"

Else
MsgBox("Clearing filter")
Me.DgvInvoiceData.FilterDescriptors.Remove(filter)

btnCustom.Text = "Show Only Custom Lines"
Me.DgvInvoiceData.Refresh()
End If

Thanks...

RichTextEditorRibbonBar Localization

Hello,
I localized RichTextEditor with an xml file (file name RichTextBoxStringsEng.xml). But I didn't find any information about to localize RichTextEditorRibbonBar.
How can I localize RichTextEditorRibbonBar?
And Find/Replace dialog, Paragraph dialog and so on, all embedded dialogs are opening at the top left of the screen.
Is there a way to open all this dialogs at the center of screen or a manuel location?
Best regards...

BeginEditMode - like Excel

I want to make editing in the RadGridView more familiar for users like using Excel.

I currently have BeginEditMode set to BeginEditOnF2. Unfortunately this goes into edit mode when:

1. The user presses F2.
2. You have a cell active (not in edit mode) and you click the same cell.
3. You have a cell active (not in edit mode) and you click another cell.

I want to only enter edit mode when:

1. F2 is pressed.
2. A cell is double-clicked.

Can you give me info on how to do this please?

Thanks

Paul

Using AutoComplete with DropDownList style

I cannot seem to get AutoComplete to behave properly when I have the DropDownStyle property set to DropDownList.

AutoComplete works with multiple typed characters only when the user is able to type very fast. Even a slight delay in keyboard activity (1/4 second or less) causes the next key press to start looking through the item list as though we are looking for a match on the first character.

As a simple example, if I have a dropdown with the following names in the item list:
Aaron
Alice
Allen
Betty
Bill
Bob
Larry

If I am looking for Allen, I can very quickly type A-L-L and the correct entry is chosen. However, even a slight delay between A and L, or between the first and second L will cause Larry to be selected.

If I set the DropDownStyle property to Dropdown, I can type A-L-L as slowly as I want and select Allen. However, this does not prevent the user from entering a value that is not in the list.

I have tried all of the AutoCompleteMode options and none of them seem to make any difference.

Is there a property that would increase the time allowed between keystrokes and still recognize it as a single entry?

[Solved] Splitter position

Hi,

I'm using RadPropertyGrid with multiple RadPropertyStore objects. The properties names are quite long and their length are run-time dependent. How can I auto resize (move the splitter) columns in RadPropertyGrid to fit contents of both the widest PropertyName and the Value.

Best regards,
Mirek
