Re: Is it possible to have both row and column selection set in DataGridView?

22-Sep-09 6:29

The DGV doesn't support multiple selection like you're describing. I've never seen an application, using the DGV, that does.

If it's unbound and just numeric data, I HAVE seen a library that does Excel emulation, which does support multiple row and column selections. I just can't remember what it's called... Cry | :((

Thanks. I was afraid of that, but I needed to check. I'll look for the library and make do in the meantime.

Can you set it to CellSelect and enable MultiSelect and then handle selecting all the cells you want programatically?

Hi,

I am using visual studio2005 and .NET framework2.0

when ever I am trying to run my ASP.NET application I'm getting "Unable to find a version of the runtime to run this Application" error message. After clicking OK button of this message , I'm getting another message stating "Unable to connect Visual Studio's Local Host Server".

If I repair / reinstall the VS2005 , the error disappears for sometime , but again it reappears.

Can any one help me out from this.

Thanks,
Amu

Remove .NET framework2.0 from your Add/Remove programs in control panel and reinstall it.

asp.menu not immediately reflecting DB changes. (C#)

Hi,

I have a few questions about caching and how to immediately reflect database changes in the asp.menu control. Currently I'm using a custom sitemapprovider and binding my menu to the sitemapdatasource. When I make a change to one of the menu items whether it be to the menu items title or sortorder it doesn't get reflected in the menu control immediately. Moreover, I have no idea when it will be reflected as I have lost patience in waiting!

So my questions are:
1) How long does it take to get reflected in the menu control?
2) How do I make the menu control refresh immediately?

thanks,
Tim

You can use update panel from ajax control toolkit and poot your menu in that update panel and set refresh time whatever you want........

You'll need to start by researching Visual Studio Tools for Office[^]

You are not going to get anyone here to write your code for you. You've been given the tools to do your own research. Research is the TOP skill a developer needs in order to be successful at this job. It has nothing to do with knowing the language or the .NET Framework inside out. Without the ability to teach yourself what you need to know when you need to know it, you're completly screwed as a developer.

The longer you screw around on the forums hoping someone will just give the answer, the longer it'll take for you to learn about how to write it yourself.

I agree with the philosophy but could you explain me then why you have already posted more then 20 000 messages in the forums if you think that I screw around in the forums if I ask for explanation.

I find a forum a fast alternative to get information instead of doing lot of research. There isn't alway a lot of time to perform research if you have deadlines you know.

By The way I don't have problems to give code snippets to a person to give them a start. But I certainly agree that performing research is the best way to become a top developer.

Reread some of the previous suggestions you have been given. The first response to your enquiry was a link (given by Mark) to the Visual Studio Tools for Office web page. It is up to you to use these tools for your research and design and code your application. When you have a specific problem with some aspect of your application then come back and ask for help.

bluepoison wrote:

Quite frankly that is your problem and not anyone else's; it is not urgent to us, as we have our own deadlines. You cannot expect the other contributors here to do your work for you. Firstly, they don't have the time - they are most likely engaged in their own research, and secondly the only way for you to succeed in this, or any other, business is through your own endeavours.

This is where you're short-changing yourself. By constantly asking a lot of questions, you're actually missing out on learning other things while you research your topic. Also, if your research skills are up to the task, asking a question in a forum is not faster than doing the research. For example, a week ago, I needed to get all the exported function names from any specified .DLL. Knowing nothing about the Win32 PE executable format, I started digging by launching Google. 2 days later, and a ton of research, I can almost read a PE file by hand, byte-by-byte. I'm still working on the library to do it for me, but my question was answered in 2 days and I've also learned about all kinds of little things that go on inside a PE file that make my debugging life a bit easier and well as some pitfalls in reading and parsing the file. It's just not possible to get an answer describing the format for PE files in a couple of forum posts and it's not possible to get all the tiny details you need to know to parse one and understand it.

Then there isn't time to do the project properly and where you have to push back on a deadline.

A very poor excuse that essentially means the project has already failed.

multithreading in c#.net

Hi All,

I have the application whose runtime argument will decides how many threads I have to create.All these threads functionality may differ by a step or two.Threads are going to use the same set of resources (Database tables,variables) etc.

To improve the application performance I planned to use multithreading.But I am a bit abash while thinking about .. since in my application the thread should continue processing in spite of any error in another thread. The sucessful run of all the above threads end up with the creation of file having consolidated data.

Can anybody help me on how to implement this scenario? Please reply.

Thanks!
