Bob,

>I have an mmTextBox placed on a web form and have bound it to a business object column using the bindingsource and bindingsourcemember properties. I also have a button next to this control with the following event code:

>// Create a new trader profit record
>        TraderprofitDefaults TPD = new TraderprofitDefaults(this.profitID, Convert.ToInt32(this.cboTrader.SelectedValue));
>        this.oTraderProfit.NewEntity(TPD);
>        if (mmSaveDataResult.RulesPassed == this.oTraderProfit.SaveEntity())
>        {
>            string nextScreen = "ProfitEditForm.aspx?profitID=" + this.profitID.ToString();
>            mmMessageDisplay.DisplayMessage("System Confirmation", "Trader Allocation Record Successfully Saved",
>                nextScreen, 3);
>        }

>The code is to add a new row into the trader profit table. This table has three columns. The two referenced above as default values and the third the value in the mmTextBox that is entered by the user (before the button is clicked to add the row).

I recommend setting a breakpoint in mmTextBox.BindBack() to see what's going on. When the web form is posted back, the text box should contain the value entered by the user (make sure you haven't turned off view state for this control).

Best Regards,
