Hi,
I think you don't have any such property "autogenerate columns" in datagrid for winforms.
Just select the fields you require to display in your database query.
Or else you can set the "Visible" property equal to 'False' for particular column in the datagrid which you dont want to display.

hello experts,
I have one question... Why ASPX pages are running more slower than any other web technology...?
I saw php sites are running too fast than the any ASP.NET application.
The latest example of it is Code Project it self. When it was in classic ASP than it run smoothly, but since the upgradation is apply on it using ASP.NET technology it running more slower and slower.
one more intersting aspect of ASP.NET is : This is the only web technology which having the compiled code and other technologies are run whole code every time. So .NET should run fast as compare to other...
How to over come with this particular problem...?

This is a dumb question. Many tests have been done, for example between J2EE and ASP.NET. No matter what the result, examining the code used will result in people pointing out ways to optimise one version or the other. There's really no way to compare apples for apples, the core benefit of ASP.NET is being able to write structured code, no-one said it was faster, although I also don't think it's slower. Each app needs to be written, performance tested and, yes, worked on when it fails to perform as hoped under extreme load. That doesn't mean ASP.NET is slow.

I have been noticing this kind of behavior from some "experts" as well, on this community. If the users are expected to maintain the decorum and dignity of this community, so are all the "heads" of this community.

Hi friends,

I have to disagree with you. Given that the OP's question was both inappropriate and ill-informed, Christian's remarks were quite reasonable. Most people who answer questions in the programming forums do so in a reasonable and understanding manner, which is often difficult with the high volume of 'noise' posts. This is a free site and no one is being paid for offering their assistance. If you are not happy with the standards of response, maybe you should be encouraging those that post to ask more intelligent questions.

I also disagree, although people can seem a little harsh at times, it is usualy because people do not pay attention to the rules... or ask a question that is so obviously a peice of homework.
Also, CP doesn't delete posts, or ban / suspend its members for their opinions. If enough people regard your post as inapropriate, or spam then it will automaticaly be removed. But thats down to the community, not because of one person.

Adding CG's post, who said CP became slow after upgradation ? Then better change your internet connection. I felt it's faster than the ASP version, and AFAIK, CP team has not completed the full upgradation process. So they might be uploading something and it cause recompilation of the site which will make it slower. For getting good performance on ASP.NET pages, optimize it, follow best practices and understand well about how it works.

Their is no way to prove you wrong...  otherwise I'll definitely give you speed demo between ASP and ASP.net version of Code project.

I think you are getting architecture and implementation mixed up here. If you write a PHP page that does nothing but return HTML, then it is going to be faster than an ASP.NET page that hits the database, pulls back a couple of thousand rows, binds them to various parts of the display and then sends that back to the client, with a couple of HTTP handlers interacting on the way.
The only way to verify speed differences is to code up two systems that do exactly the same thing, in exactly the same way, and measure the time over a period of interactions.

Errm no. What about CGI code? What about Java applications? Please check your facts before making bald statements like this.

That's answer for that I'm looking for.
I already make some pages in ASP, .NET (same functionality and test them) and ASP.NET application is running slow as compare to asp.
Sorry about that compiled code line.... 
But here some people underestimate me and some start fighting without giving proper answer of my question.
One thing I want to tell
"NO ONE IS THE PERFECT IN THE WORLD".
So you are sit here to helping people or underestimate them....?

Thanks in advance.

It all depends on what your 'themes' are. Different colours? Different images? Different layout even.
Still, if you think about it for a moment, its not that difficult.

hi,
i have two arrays..
first arraylist consists of 1,2,4,6,8;
second arraylist consists of 2,6,9,8
i got the commoon items using the following code..it is working fine
for(int i=0;i<strOldItems.Length;i++)
{
strTest[i]=strOldItems[i];
for(int j=0;j<strNewItems.Length;j++)
{
if(strTest[i]==strNewItems[j])
{
if(strCommon.Length>0)
{
strCommon=strCommon+","+ strTest[i];
//Response.Write(strTest[i]+",");
}
else
{
strCommon=strTest[i];
}
}
but i need the items which is in first array and which is not in second array..for that i wrote the following code..but it is not working..
for(int i=0;i<strOldItems.Length;i++)
{
strTest[i]=strOldItems[i];
for(int j=0;j<strNewItems.Length;j++)
{
if(strTest[i]!=strNewItems[j])
{
if(strReject.Length>0)
{
strReject=strReject+","+ strTest[i];
//Response.Write(strTest[i]+",");
}
else
{
strReject=strTest[i];
}
}
}
}

hi,
it is not giving any error,
to get the same values from the two arrays ..i wrote the logic like this,
first array first element checks with all the second array elemnts..if it find any matches ..it returns the matched value..like second element with all the elements of second array.
but to get the elemenet which is in first array and which is not second array..
i wrote like this,
first array element checks with the all the elements in the second array..if he does not found any matches it returns the unmatched values ....this is wrong na..becasue this first elemnt unmacthedvalues may be equal to the second element in the first array
how can i write the logic for this

Hi all,
I want to use 3 lists ,list1,list2 and list3...
list1 contains the list of tables.list2 contains the list of columns corresponding to the table in the list1.
user selects the columns by checking them and presses a button and the column is moved to list3.
I have an idea to do it.But the main problem,when the user finishes the selection ,I want to see which tables are selected and which columns corresponding to which tables are selested...

you can do one thing , insted of read the Table name in List box use a combobox, when selet one table from combobox all column name will come with in a list box and you can move to another list box. Which make simple and easy.
Or you can use collection for that !!!!!!
Good luck !!!
