How to disable a custom toolbar button using C# code

Hi All,

I am facing a problem with Disabling of a custom tool bar button. Actually i am making "Enabled" property of my custom tool bar button to "false". But it is not disabling. If i made "Visible" property of that toolbar button to "false", then it's working means the control is in-visible. But my actual requirement is i should disable the button not as in-visible.

Can any one please help me. It's very urgent. Thanks in advance.

Below is my template and code details:

In My Template manifest.xsn file, below is the code for my custom tool bar.

<xsf:toolbar caption="Custom ToolBar" name="CustomToolbar">
    <xsf:button name="btnSaveToDatabase" icon="SaveToDatabase.gif" tooltip="Save To Database" showIf="immediate"></xsf:button>
    <xsf:button name="btnConvertToWord" tooltip="Show In Word" icon="Word.gif"></xsf:button>
    <xsf:button action="btnRemoveApprover" caption="Remove Approver" tooltip="Remove Approver"></xsf:button>
    <xsf:button action="btnAddApprover" caption="Add Approver" tooltip="Add Approver"></xsf:button>
</xsf:toolbar>

Based on the current position in the form i need to disable some of the custom tool basr buttons, say for example "btnRemoveApprover and btnAddApprover". And these buttons i am using to Add/Delete a row to myApprovers table.

To get the current selected section from the form i raised an OnContextChanged event.

below is my code:

[InfoPathEventHandler(EventType=InfoPathEventType.OnContextChange)]

public void OnContextChange(DocContextChangeEvent e)

{

CommandBars objCommandBars = UnwrapCommandbarsObject((ObjectWrapper)thisXDocument.View.Window.CommandBars);

CommandBar customToolBar = null;

try

{

customToolBar = objCommandBars["CustomToolBar"];

}

catch

{

return;

}

if (e.Context.nodeName != "my:Approvers") // my:Approvers is the section for adding/deleting approvers in my form.

{

customToolBar.Controls[3].Enabled = false;

customToolBar.Controls[4].Enabled = false;

}

else

{

customToolBar.Controls[3].Enabled = true;

customToolBar.Controls[4].Enabled = true;

}
