View 2 RepliesCannot Remove Rows In Datagridview
Aug 11, 2011My datagridview is bound to a data table. I want to filter the datagridview without affecting data table.

So I pass datagridview by reference to a function PassFilter which removes unwanted rows in datagridview. I can see that it does execute rows removal in datagridview. But the problem is that when datagridview is shown on the form, it is unchanged, the same as the data table. I do not understand why rows are not removed on datagridview The code is as follows:

Asp.net - No Rows Being Returned From Dataset JUST On IOS Using MVC 3
Aug 11, 2011I have a model that returns a dataset to a view and builds a list. The crazy thing is that I have tested this code with IE, Safari on Mac and Windows, Chrome and Opera and all return data. However, on the iPad or iPhone, zero rows are returned from the dataset object. It seems that the model is in fact passing the dataset to the view. I am using jquerymobile to render the view for the iOS devices and have taken that out of the mix to test and it still doesn't work.
