I am attempting to filter results in a RadGrid.

What I am looking for is the programmatic equivalent of selecting the all but (blanks) or not (blanks) option from the filtering area.

I will apply filters of " " and "" but still will get results of " " or varying amounts of whitespace that I don't want in the results. I cannot do this with a composite filter as I cannot capture all of cases of whitespace, but removing (blanks) achieves the correct results.

Thanks

More than 20 (25) waypoints.

Hi there,

I have read that it should be possible to add 'Viawaypoints' in combination in normal 'Waypoints'.

I however cannot find a c# method other than 'reqRoute.Waypoints.Add(l_sWaypoint);'

What is the right manner to have more than 25 waypoints in my route?

Kind regards,

Victor

Row Double Click

Is there a way to differential data row double-clicks from double-clicks in the header or scroll bar. RadGridView::DoubleClick seems to fire when anything is double clicked, and the sender is always the grid, not the specific element.

Looking at MouseDoubleClick, I think I might be able to use the event's X and Y to get the child control at that position and check to see if it's a data row. Are there other options?

SelectedItems MultiLine?

Hey Guys

I would like the selectedItems to line wrap when required. Ideally I would like the control to grow in height when the user selects enough items that require a new line. ( the same way as the Telerik MultiSelect Web Controls work)

See screen Shot.. the top control has the minimum height updated to what I would like to be the maximum height , however the selected items just dis appear off and cannot be seen.

I have been fiddling with the minimum , maximum sixes etc, but I don't seem to find how to achieve this. ( Maybe it's related to how I add the selected items?)

Any help most appreciated.

Horrific crashing. What have I done wrong?

I was receiving exceptions when attempting to set range at runtime on the range selector.

System.NullReferenceException
HResult=0x80004003
Message=Object reference not set to an instance of an object.
Source=Telerik.WinControls.ChartView
StackTrace:
at Telerik.Charting.CombinedBarSeriesRoundLayoutStrategy.ApplyLayoutRoundingVertical(LayoutContext context)

So I stripped the form out of the main project and I've put it into a sample application. Commenting out lines 13 and 14 of FrmPerformanceChart.cs leads to different levels of nightmare.

Link to project is sample: testchart

DropDownListEditor ComboBox Mode

Is it possible to set a DropDownListEditor in a PropertyGrid to behave like a ComboBox?

I have tried setting the DropDownStyle property to RadDropDownStyle.DropDown, which looks as though this should setup this behaviour, but it does not seem to work. It is not possible to enter text even when this has been set.

Is there an additional step that needs to be taken in order for the dropdown list to allow text entry?

Thanks,

Chris

Disable MultiColumn ComboBox from always selecting a value after information is added?

The MultiColumn ComboBox is always selecting a value after data is added to it. Is it possible to have it work almost exactly the same as the DropDownList?

For i As Integer = 1 To 12

Me.MultiColumnComboBox1.EditorControl.Rows.Add(i, "Row " & i)

Me.RadDropDownList1.Items.Add(i)
