This is a very common problem in WPF, if you support Drag & Drop within your Items control or across the controls like ListView, TreeView etc. and your List contains hundreds of items then it’s very hard to drag an item at the bottom to the top. Various solutions are available on net for this -

Today, I am going to start with the task of memory profiling the WPF application, on which I am working from past few months. I have successfully done this in past, fixing a lot of memory leaks and improving the performance of WPF applications; As in past, I am hopeful of fixing some very interesting bugs and improve the application performance.

In this post I am going to share my experience on how I achieved the functionality to resize DataGrid row/column from any cell in that row (not just the row header). We needed this functionality as our user can hide the DataGrid headers and it is not possible to resize the rows/columns after that.

I am really very happy right now, for the past 4 days me and my team were trying to solve a very trivial bug in our application and finally it got resolved by just adding x:Type in our RelativeSource bindings;Can you believe this, a production issue getting resolved just by this simple change, I couldn’t; so I tested this fix at least ten times to believe it

While developing WPF applications, you will notice a lot of binding errors being displayed in output window; like this

In one of the application I am working, lot of converters were used for determining the value of a property based on various conditions (values of other properties); It’s not required to use these converters at all and these can easily be replaced with Triggers. I don’t have any statistics in favor of triggers at present but some problems I see in using converters are –
