System Generate Error Message Specify Cast Is Not Valid


public int EditGrid(DataGrid myGrid, string myValue)
{
DataTable myTable= null;
myTable= (DataTable)myGrid.DataSource;
}

You are trying to put a datasource into a table object => that's a big no no ;)

And by trying to convert the datasource to a table object ...., no that is not the way cause simply a datasource isn't a table object.

If I'm not mistaken it my work like this : myTabel = myDs.Tables[int index];
and myDs is the datasource of your datagrid

but we can do this in vb.net

myTable = CType(myGrid.DataSource, DataTable)

could be but this is C#.
Just get the datasource of your datagrid and then get the table from the datasource
