datagrid

问题 I am trying to display students in a datagrid that have "yes" as active. If the student has "no" as active, the form has to hide it and only show the students with "yes".

问题 I have a SQL CE database, which is beyond my control, that has fields in the format of ., complete with a period in the column name. The columns will always be different, so I cannot have a strong-typed data field. I've been tasked with displaying dynamic table data into a DataGrid.

问题 In the application I'm developing at the moment I'm using a datagridview to display data. To fill it, I've to press a button and a backgroundworker will start running, it will fill a datatable and when it's finished running it will use the datatable as the datasource for the datagrid.

问题 my mission is to select an item in a DataGrid instance with nothing but the coordinates on screen. We are implementing right-click functionality in our Flash application, with the goal of being able to right-click a DG row, which would select that row plus show a popup window containing some context commands. I have managed to get the right click event into my Flex app with the help of this site. Further progress so far has been to obtain the DataGrid instance via var objects : Array = this
