Data Grid View control is one of the coolest features of Dot Net Framework. # In the Add Reference dialog box, select the tab indicating the type of component you want to reference. Hello Rahim, Thanks for your code for update from Grid view to database….
You can use this control in Windows Form using Wizard or programmatically. Select the components you want to reference, and then click OK. But unfortunately when i debugging this code an error is coming ” System. Data Table’ is a ‘type’ but is used like a ‘variable’ ” can you please suggest that how can i improve that…….
I have done this kind of stuffs with vb6, has not done it with C#. the better idea is create a new function in datagridform, then shift(cut & paste) the code which you use to fill datagridview in a new function(means refactor the code to function).
Now when you close the add form call that function.
