ControlContainerTool and toolbar

Viktar posted over 16 years ago

Hi All, I am trying to add custom control to the ribbon tools using the code below. When form is loaded it trows exception: Object reference not set to an instance of an object. The same code for the PopupControlContainerTool works correct. Could anybody give me a hint what is the reason? Thanks in advance. ControlContainerTool controlContainerTool = new ControlContainerTool("textControl"); controlContainerTool.Control = new TextControl(); controlContainerTool.SharedProps.Caption = "textControl"; controlContainerTool.SharedProps.AllowMultipleInstances = false; ultraToolbarsManager1.Tools.Add(controlContainerTool); group.Tools.Add(controlContainerTool);

Its tough to say without a stack trace of the error or knowing how the 'group' variable was obtained. However, if it works fine with one tool type and not another, it is probably a bug. I would recommend submitting the issue to the support group: http://ko.infragistics.com/gethelp.

Mike, thank you for your answer. If possible could you look at stack trace below? I found that UIRoleOnMenus and UIRoleOnRibbonGroups properies are null after adding control to the ribbon. But when I use the same code for the PopupControlContainerTool object these proprties are not null. Is it possible that the reason of the exception is in UIRole properties? BTW I receive 'group' variable as RibbonTab tab = ultraToolbarsManager1.Ribbon.Tabs["ribbon1"]; RibbonGroup group = tab.Groups["ribbonGroup1"]; Thanks in advance.

After looking at the stack trace, it is still difficult to determine the problem, but it seems like it should work. Submitting a sample to the support group using the link above would be the best way to determine how to fix this issue.

Vru,
It sounds like you want to use the UltraGridRowEditTemplate, which provides functionality for modifying grid cells from an external control. The general help area for this control can be found here. There is also a sample that ships with the NetAdvantage SDK that illustrates how to use this; I believe that it is contained within the Grid Samples Explorer.
