[Solved] RadListControl Selection Issues When Re-Ordering

When SelectionMode is set to 'MultiExtended' the RadDataItem.Selected property will behave as if the Mode is 'One' (clear all other selections).

When SelectionMode is set to 'MultiSimple' and a RadDataItem is added witht the Selected property set to true then the RadDataItem will always show as selected but cannot actually be selected or de-selected. Also when the list is re-ordered then ActiveItem does not stay on the RadDataItem that was active before the re-order.

Thanks.

FillType not working correctly

I have a very simple radChart and I am attempting to set the Fill Type to Gradient and use two KnownColors as the Main and Secondary Color. I have tried to do this progamatically and through the property panel. When setting the property in the property panel from Solid to Gradient it immediately goes back to gradient, however I am able to set it to hatched. Here is the code I am using. The is still solid white. Any help would be greatly appreciated.

KnownColor clrTopBackgroundColor = KnownColor.White;

KnownColor clrBottomBackgroundColor = KnownColor.LightBlue;

radChart1.PlotArea.Appearance.FillStyle.FillType = FillType.Gradient;

radChart1.PlotArea.Appearance.FillStyle.MainColor = Color.FromKnownColor(clrTopBackgroundColor);

radChart1.PlotArea.Appearance.FillStyle.SecondColor = Color.FromKnownColor(clrBottomBackgroundColor);

radChart1.Update();

radChart1.UpdateGraphics();

Thank you,
Will

RadGridView Filter - 'Contains' option required on numeric column

Hi
Is there any way that I can override the default RadGridView Filter behaviour where the 'Contains' option is not presented for numeric fields?
I need the 'Contains' option to appear on a numeric column. I know that I could change the datatype on the table but that's not really an option for me.
I am a licensed user of RadControls for WinForms Q1 2010 SP2.
Any help is appreciated.
Thanks

Error when clicking filter icon for GridViewComboBoxColumn

I have a GridView with a GridViewComboBoxColumn for choosing units of measure. My grid is bound to a DataTable of parts data. One of the fields for a part is 'unit of measure' but it is not a required field. I am using the Excel-like filtering. If I have a null value in the 'unit of measure' field and I click the filter icon, I get an exception that says: "Object reference not set to an instance of an object.". This only happens when I have a null value for that field in one or more rows. Here is part of the stack trace that seems to indicate that the error happens during the attempt to get the column's distinct values.

A first chance exception of type 'System.NullReferenceException' occurred in Telerik.WinControls.GridView.dll System.NullReferenceException: Object reference not set to an instance of an object.
at Telerik.WinControls.UI.RadListFilterMenuProvider.GetDistinctValuesTable(GridViewDataColumn column)
at Telerik.WinControls.UI.RadListFilterMenuProvider.CreateListFilterMenuItems()
at Telerik.WinControls.UI.RadListFilterMenuProvider.CreateFilterMenu()
at Telerik.WinControls.UI.GridHeaderCellElement.FilterFunctionButton_Click(Object sender, EventArgs e)...

Should I be able to have null values in a field bound to a GridViewComboBoxColumn and expect filtering to work properly?

Here are the properties I have set on the grid:

gridCatalog.AllowCellContextMenu = false;

gridCatalog.AllowDeleteRow = false;

gridCatalog.AutoGenerateColumns = false;

gridCatalog.EnableFiltering = true;

gridCatalog.EnableGrouping = false;

gridCatalog.NewRowEnterKeyMode = RadGridViewNewRowEnterKeyMode.EnterMovesToNextCell;

gridCatalog.EnableCustomSorting = false;

gridCatalog.EnableSorting = true;

gridCatalog.MasterTemplate.SelectLastAddedRow = false;

gridCatalog.MasterTemplate.EnableCustomSorting = false;

gridCatalog.MasterTemplate.EnableSorting = true;

gridCatalog.MasterTemplate.ShowHeaderCellButtons = true;
