I am not sure if this is a infragistics specific problem, but since I am using infragistics controls, I thought I should post this question here too. I have a WebTab consisting of UltraWebgrid, WebImageButtons, WebGroupBox organized in asp:Table roughly in format below tab updatePanel Table TableRow TableCell UltraWebGrid WebImageButton1 WebImageButton2 WebImageButton3 WebImageButton4 TableCell TableCell igmisc: WebGroupBox asp:Table asp:TableRow asp:TableCell Label1 asp:TableCell asp:TableRow asp:TableRow asp:TableCell WebTextEdit asp:TableCell asp:TableRow asp:TableRow asp:TableCell WebImageButton5 WebImageButton6 TableCell TableRow Table /igmisc: WebGroupBox /asp:TableCell /asp:TableRow /asp:TableRow /updatePanel /Tab Everything is functionally working good except when I click anywhere on the WebImageButton1 is clicked by default. It is especially irritating when I am on WebTextEdit and hit enter - I want to activate WebImageButton5 instead WebImageButton1 is getting activated. I have all the buttons set to AutoSubmit = true, ClickOnEnter=False. I have not set the TabIndex currently. But I tried setting the tabindex in the order I want for all the buttons and Text boxes but it is still having the same result. Can you please let me know which property on Tab/Page/UpdatePanel this problem might be related too? I hope my formatting shows up when posted. Thanks, Shalini.
