       if (this.datc.fnGetDataConnection())
       {
            this.dataGrid1.ReadOnly = true;
           this.dataGrid1.DataSource = datc.dSet.Tables["student"];
           // DataBinding of TextBoxes
           fnGetDataBindingForTextBoxes();
                     fnSetCurrencyManager();
           //Record numbers in the StatusBar

Solution 1

Since you have not shared your code, based on what you say, it sounds like you call the same code more than once in your program to reload your data source - as a result, the code is calling Control.DataBindings.Add twice with the same parameters. This would attempt to add a duplicate binding to the DataBindings collection - leading to error.

One solution is to clear the DataBindings collection before you add your new binding, something like:

C#

Me.TextBox1.DataBindings.Clear();
Me.TextBox1.DataBindings.Add("Text", myDataTable, "Col1Name")

now, code shared

Try to put:
this.dataGrid1.DataBindings.Clear();

before assigning datasource. See if it helps.

Sandeep Mewara 19-Sep-12 3:57am

Then you need to clear/reset that too!
