Thanks Mike

It sounds like there may have been a bug in 7.1. Unfortunately, this version is no longer supported, so you will have to upgrade to a later version or a newer hotfix of 7.1 to get this working.

 Hi

Thanks for the reply.

The code you have sent is worked for me, i.e I didnot get any exception. But still I didnot get the separator.

I am using Infragistics  2007 Volume 1 CLR 2.0 build. Is this problem due to the my version of the Infragistics?

Looks ok to me. And for me it works, at least with Infragistics 2008.2 build 2022.

I would try to get the new instance returned by the AddTool method on ToolsCollection of the ribbon group, set it's InstanceProps and check to see if they are set on the instance referred by m_ToolBarManager.Ribbon.Tabs["Charts"].Groups["Betting Charts"].Tools["Investment"]:

ButtonTool addedInvestmentTool = m_ToolBarManager.Ribbon.Tabs["Charts"].Groups["Betting Charts"].Tools.AddTool(InvestmentTool .Key);
addedInvestmentTool.InstanceProps.PreferredSizeOnRibbon = RibbonToolSize.Large;
addedInvestmentTool.InstanceProps.IsFirstInGroup = true;

if (addedInvestmentTool.InstanceProps.IsFirstInGroup != m_ToolBarManager.Ribbon.Tabs["Charts"].Groups["Betting Charts"].Tools["Investment"].InstanceProps.IsFirstInGroup)
{
    throw new Exception("IsFirstInGroup property could not be set!");
}

 Hi Emanuel Haisiuc

Thanks for the reply.

Actually I setting the IsFirstInGroup to true exactly the way you have said.  The code I am using is

            ButtonTool  InvestmentTool = new ButtonTool("Investment");
            InvestmentTool .SharedProps.Caption = "Investment";
            InvestmentTool .SharedProps.Tag = this;         
            m_ToolBarManager.Tools.Add(InvestmentTool );
            m_ToolBarManager.Ribbon.Tabs["Charts"].Groups["Betting Charts"].Tools.AddTool(InvestmentTool .Key);
            m_ToolBarManager.Ribbon.Tabs["Charts"].Groups["Betting Charts"].Tools["Investment"].InstanceProps.PreferredSizeOnRibbon = RibbonToolSize.Large;
           
           m_ToolBarManager.Ribbon.Tabs["Charts"].Groups["Betting Charts"].Tools["Investment"].InstanceProps.IsFirstInGroup = true;

Can  you suggest me, what is going wrong in this code.
