I have carefully created a test page based on the cmbCustomer code which is available in WebForm2.aspx page in the sent sample. However, I was unable to reproduce the slow performance reported problem in my local end.

I’m willing to advise you further but in order to do so I would need you to elaborate on your specific scenario and possibly give a step-by-step guide that I can use to observe the problematic behavior.

I hereby attached a sample file with the site master page and the web combo with linked settings.

Actually i'm using web combo link settings to connect multiple combos where I feel the posting back of pages tend to load the combo box as each postback fires.

Please let me know how to handle this.

Thank you for the sent sample.

I modified the sample in order to have it works in my local end. The list below shows the detail changes:

• Removes MMI namespace in WebForm3.aspx.cs (line 10; line 11; and line 12) since it could not be found in my local end.
• Modify the SqlConnection in WebForm3.aspx.cs (line 17 and line 18). I added Northwind.mdf file – which is available in %ProgramFiles%\Intersoft Solutions\WebUI Studio for ASP.NET\Data folder – into the App_Data folder of the project and modify the SqlConnection to the Northwind.mdf database.
• Modify the SqlCommand of bindAccount() and BindBudgets() method. I’m using the Categories and Products table of Northwind.mdf as a replacement to sp_anp_accounts_select_byuser and sp_anp_budget_master_select stored procedure.
• Modify each of the WebCombo columns structure.

Unfortunately, I’m still unable to reproduce the reported performance issue by using the modified sample. I enclosed the sample as attachment. Please have the sample evaluated on your end and let us hear your feedback.

For your information, I tried to reproduce the reported problem use WebForm3.aspx sample file.
