winforms - gridview row filter -

I have named gridview with 800k rows myGridView One of the columns is named NAME is and can have value in Alex (1) , where there is a current serial number for Alex. When I insert the new rank for Alex, I want to place it with the value of the name "Alex (N)" where n is the smallest number that has not been taken. I think I should filter something like this: var rows = (gridview in all objects). Select (where rows NAME.IndexOf ("Alex (") & gt; -1)

and it will send me all code for Alex (some numbers) And now I have to filter by number I think ... how to properly filter which I have not been taken to return to the smallest number yet? Can it be faster? < / Div>

  First of all, I should mention that the code you pasted will not work Because this does not provide grid line archive. Also, even though this code works, it will work very slowly as it will have to filter 800k rows on the web server. Do not you think the DB server requires the necessary information Is it better to request, which is optimized for working with such questions and will be able to process your request faster?

visual studio 2010 - How to reinstall MVC 2 tools for VS2010? -



    I uninstalled ASP.Net MVC 2 device for Visual Studio 2010. How can I restore it? MVC2 downloads seem to include only the VS2008 device.   Whatever I said, says that MVC 2 has been included in VS2010, but the installation of an improvement did not fix it, and MVC 2 is not listed. Add VS2010 / Select a component in the Remove screen.      You will get your VS2010ToolsMVC2.msi VS2010 DVD under WCU \ ASPNETMVC - hopefully it will do!    






Git Bash script to check whether repo has any commits? -



    I have a script on which I need to work differently if there is one, which is one or more , Commits. What is the best way to do this?   Something like this will appear in the proxy code.    #! / Bin / bash if [[`git log_count`] ==" 0 "]]; Then there is no commodity for this repo. # What goods ... and echo are "one or more committed!" # What are the other things?    Any ideas?      you can    git rev-parse -verify HEAD    (after :)     This is a pipeline command, and its behavior vs. "  git diff " There is very little possibility to change   I find it more pronounced  rev-parse -verify  means "is this a valid object name?"    This is your  show-ref .  You ask "Is there anything in this safe / head in the safe?"  I ask, "what current  head  exists?"   In practice, both of these are fair tests, because once you have a branch, so to achieve the  HEAD , some mock values will indicate manually lack of editing It is very diffic...
