Cellvalidating in datagridview in c speed dating events scranton pa
The problem is now, that the error-symbol (and the error text) is not displayed (in the cell). Cancel the cell looses the focus and error-symbol is displayed.How can I achieve that the cell remains in edit mode and the error-symbol is displayed too?m_Sqlstr = "Select Distinct RFID, Prod_Code, Lot_No From Scan Stk Where Batch No = '" & str Batchno & "' " m_Sql Cmd = New Sql Command(m_Sqlstr, Con) Con. Close Connection) With m_Bindingsrc Detail While RFIDReader. For a code example that uses an unbound Data Grid View control, see Walkthrough: Creating an Unbound Windows Forms Data Grid View Control.The Data Grid View control is highly configurable and extensible, and it provides many properties, methods, and events to customize its appearance and behavior.When you want your Windows Forms application to display tabular data, consider using the Data Grid View control before others (for example, Data Grid).If you are displaying a small grid of read-only values, or if you are enabling a user to edit a table with millions of records, the Data Grid View control will provide you with a readily programmable, memory-efficient solution. Follow these steps and you will see how to write a data driven application without writing a single line of code.
In my next articles, I will talk about more detailed features of the Data Grid View control.
The Data Grid View control supports the standard Windows Forms data binding model, so it will bind to instances of classes described in the following list, The Data Grid View control supports data binding to the public properties of the objects returned by these interfaces or to the properties collection returned by an ICustom Type Descriptor interface, if implemented on the returned objects.
Typically, you will bind to a Binding Source component and bind the Binding Source component to another data source or populate it with business objects.
To copy the code in this topic as a single listing, see How to: Validate Data in the Windows Forms Data Grid View Control.
The following code example demonstrates how to use the Cell Validated event to clear out the Error Text property.
