C# datagridview invoking the getformattedvalue function

Question

3.00/5 (2 votes)

See more:

I derived a new class from DataGridViewTextBoxCell in my application and overrided the function GetFormattedValue

In GetFormattedValue, I do some data binding (for example I read a ID from the database on the web and I show the corresponding name of that item from my local information which are pre-read in a datatable).

However, some databinding need to query from the web. It slowed down the application so every time when I need to do the bindings related to the web, I open a new thread to do the query, and show the original value(e.g. the item's ID) at the moment first.

The problem now is I don't know how to invoke the GetFormattedValue function when the query is finished so that it would show the desired value (e.g. the item's name).

Anyone could help? Thanks a lot=]

GetFormattedValue is a protected function and in those threads you could not put in the parameters needed to call GetFormattedValue. So I can't call it directly.

Btw, I get the answer now, the Refresh() functon of the datagridview could solve the problem.

Hope this could help some people =]

Why don't you invoke the getformattedValue function for a particular cell in the end of the thread. If this does not help please does not help please elaborate your problem so that i could get the exact idea of your problem.
