That should be possible with the DX controls. Quite a bit of code would be needed, but the framework should help with that.

Your expectations are a long way beyond a report builder, any report builder. All of them will handle to design and layout of the reports you require, deciding on the layout of the report is up to the user designing the report, not the report builder software.
Storing the query and report code into a database is up to you to build. I have done all of the above using a number of reporting tools over the years so there is nothing new about your requirements. It will require you to a lot of work managing the infrastructure.
You will not need to create your own report designer, use one of the commercially available ones.

Hi,
where can i find a GOOD Example for C# Datagrid and CRUD-Functionality, with SqlDataAdapter.
I want to Insert, Update, Delete Gridvalues with Bulk via "Update-Button"
Thanks and
Regards

What database are you using ?
iirc, MySQL has a plugin to Visual Studio ?2010+ that can generate a grid based or page based CRUD program

I have a function fired by a buton to select an entire row of checkboxes of a datagrid and set them with the same value (true or false), similar to the excel filters. If all checkboxes of the row are true than if I click the button, they all become false, otherwise they all become true. But it only works when all the checkboxes are simultaneously true or false, if one of them is true, they all become false instead of true as it was supposed to, like in excel filters. This is due to the last part of the code that is commented which is not throwing the expected result. Can anyone help to see the problem cause?
public void seleciona_check()
{
for (int i = 7; i < grid_lic.ColumnCount-1 ; i++)
{
for (int j = 7; j < grid_lic.ColumnCount - 1; j++)
{
if (grid_lic.CurrentRow.Cells[j].Value.ToString() == grid_lic.CurrentRow.Cells[i].Value.ToString())
{
if (grid_lic.CurrentRow.Cells[i].Value.ToString() == "True")
{
Convert.ToBoolean(grid_lic.CurrentRow.Cells[i].Value = false);
Convert.ToBoolean(grid_lic.CurrentRow.Cells[3].Value = false);
}
else if (grid_lic.CurrentRow.Cells[i].Value.ToString() == "False")
{
Convert.ToBoolean(grid_lic.CurrentRow.Cells[i].Value = true);
Convert.ToBoolean(grid_lic.CurrentRow.Cells[3].Value = true);
}
}
}
}

Your code needs quite a bit of improments:
1. why start at 7:7 (i and j)? Why go until grid_lic.ColumnCount -1 instead of grid_lic.ColumnCount?
2. Your i and j iterate through columsn onlyl not through rows at all.
3. Why do you set that CurrentRow.Cells[3] to false or true?
4. Why the double statements (Convert.ToBoolean...)?
5. The Convert.ToBoolean seems un-needed
6. You need to first check ALL cells to see if they are all true or not, so that you'll know how to set them
7. Then, once you've done 6., you have to do a simple for..., and set each checkbox to either false or true (what you computed at step 6.)
Best,

Because the checkbox columns are on the column nr. 3 and from 7 untill 19, in a 21 columns datagrid.
John Torjo wrote: 2. Your i and j iterate through columsn onlyl not through rows at all.
I'm not interested in going through rows, but only through the columns of the selected row.

Because being checkboxes, only booleans are read.
John Torjo wrote: 6. You need to first check ALL cells to see if they are all true or not, so that you'll know how to set them
Isn't the cycle in the code doing that? What's the alternative?

I will address your other points at a later time. Please note that the following code
"Convert.ToBoolean(grid_lic.CurrentRow.Cells[i].Value = false);" is meaningless:
1. Convert.ToBoolean makes sense only if you want to assign the result to another value, like
x = Convert.ToBoolean(y); In your case,you don't need that.
2. And false and true are already booleans.

John

You should be able to use a variation of this code
public void CheckGrid()
{
List<int> trueIndices = new List<int>();
for (int i = 7; i < GridItems.Count - 1; i++)
{
if (GridItems[i])
{
trueIndices.Add(i);
}
}
bool setValue = trueIndices.Count == 0 || trueIndices.Count != GridItems.Count - 8;
for (int i = 7; i < GridItems.Count - 1; i++)
{
GridItems[i] = setValue;
}
}Note that you would need to convert my GridItems calls into your grid_lic... calls but this should be incredibly trivial for you.

I replaced GridItems for grid_lic, and it throws an error in grid_lic[i], with the message no overload method fot 'this' takes one argument.

It would have to be to your cell level - my version was just a list of booleans. Yours would have to be something like grid_lic.CurrentRow.Cells[i] (remembering to convert this to a boolean).

Now it is working, the problem was that I didn't convert grid_lic.CurrentRow.Cells[i] to a boolean.
But my idea was to not use a list, despite this probably being the simplest way to achieve the result.
Thank you.

You're welcome - you could, of course, use a combination of booleans if you wanted - this was simply a quick example of how you could do this.

Hi there!
I'm just trying to use dtsearch desktop/engine on my website and I was told to use C# to program it into php or sth....
I Dont know how to do programming for dtsearch to apply to my website/host so that people can use my database search engine....
and in years to come, I'm gonna turn it into android progrm
please help me, I could give you some 25 $......I'm not rich enough
thanks a million ways to die in the west juno!

We don't charge for help here: if you want to pay, thn go to vWorker.com and ask there. $25 should get you a complete Android app if you don't give a damn if it works at all...
But I'd start by asking the people who wrote dtsearch (whatever that is) as they will probably have a much better idea and possibly even tutorials...
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

As you were told when you posted this in QA two days ago[^], if you have questions about the code in an article, use the forum at the bottom of the article[^]. The person who wrote the code is the most likely to be able to help you.
Reposting your question in a general forum will only serve to annoy the people who answer questions here, because you're duplicating work. Particularly so when you have completely ignored the advice you were given in response to your previous post!

So I wasn't sure whether to post this here or in the database section, but here it goes. I have a 'logbook' that I'm developing which is basically a simple message board. Where I'm drawing a blank is how to format the data coming out of the database for the printable report. The database is set up so that all the messages are stored with various headers and a parent/child structure in a single table. You can have multiple child replies to a single parent, but only 1 level deep. Where I'm drawing a blank is how to structure the data for use in the printable reports. Any help would be massively appreciated as I'm drawing a blank as to which direction to go with this.
Here's the desired report structure[^] and the current data format[^]

From your post it is difficult to understand what you want to achieve or what the problem is.
If it is a single table, I'm unsure what you mean with "how to structure the data". Linking the records seems (from your text) easy enough. What's the report for? What data should be on there? For whom is it? You're not asking for a report structure, or are you?

Thanks for the reply. I updated the original post with some pictures to see if that helps explain it.

Hello,
Much clearer, thank you.
I'm not sure what everyone has against Crystal Reports, I worked with it and never had any issues.
I think from the other answers a quick tutorial is indeed a good idea. Many report builders allow grouping/summaries and even graphs on the fly. Playing with it is the best way to learn.
Not sure about other reporting tools, but Crystal Reports allows basically two ways of fetching data. You select data from .Net and pass it to the report document allowing more dynamic control or (my favorite) you build a template and just pass some parameters from .Net to it. The report document will fetch the data itself and build the report. (advantage is that you can test the report outside your application)
Concerning the report format I can only give the advice what I always do. That's asking yourself what is important. I use the 7 seconds rule. The first thing any user asks himself when seeing a webpage, a report, a document, ... is "What am I looking at". Attract their attention with showing what the report is about. The next 7 seconds are navigation. The user passed the first 7 seconds and now wants to know how the thing is constructed. (layout, where is which data, etc ...) After that you have their attention and only then will they look in detail.
(PS: I say 7 seconds, it could be 3 or 5 or 2.45, but you get my drift)
Hope this helps.

I suggest you consult the documentation for the (Sql Server / Visual Studio) Reporting Services and do one of the "walk-throughs".
That will take you through:
1) Starting the report designer / builder
2) Specifying a data source (I.e. database tables)
3) Selecting records
4) Fields to report on
5) Sorting
6) Formatting
7) Grouping
8) Parent-child reporting
etc.
Reporting Services Tutorials (SSRS)[^]
Once you have something going, you can ask more specific questions.

Thanks! I didn't know they covered Parent-Child grouping.
