I'm working with datagridview.I found an example on the web about creating a datagridview: firs I make my array containing data, then I make a datatable from array, then I make datagridview from datatable.I don't know if it's the correct way but it seems work.In a column I make random numbers for test: for example I have on column "Time" these values: 1155, 1725, 584, 996, 1352.Then I try to sort with code when I press pushbutton: it doesn't work because I have the values:1155, 1352, 1725, 1758 (until now it seems to work correctly), but then I have 584 and 996 values: wrong!Ok, let's try with the manual sorting: same result.I filled cells with "integer" values, let's try using strings, then I used "value.tostring" same result.I also tryed to fill strings with blankspaces to obtain same length, but nothing changed. "1155", "1352", "1725", "1758", " 584", " 996".Then I tryed to fill with "0" values:"1155", "1352", "1725", "1758", "0584", "0996".The same.How can I fill cells values?
View 9 Repliesi have a combo box that i'm trying to fill from a database, managed to get it working through the wizard and the form view method but could do the next bit that way. I then started to try it the coded way, got the database linked but it only shows the first name in the database, how do i get it to show all the names in the database?
this is the code for the form

I'm trying to get a combo box to fill itself from a MS access database field but I can't get it to work. I can get it to work at school but not at home. Also can't get a program that worked at school to work here so I'm guessing that somewhere there is something blocking the connection to the database. I've gone into the MS access trust center and looked at the settings there but I can't see anything that would be stopping it. I just need to find that setting (if it is indeed a setting) wherever it is and fix it so that I can access my database. I am not using visual basic from access I am accessing access through visual basic.
I can't get it to work with an ADO connection, either. Also when preview data via clicking smart arrow on the combo box then going to preview data I can see the data just fine. Also I just noticed I get two lines in my output after the file is run that say "A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll" I don't get these lines if I comment out all the code for the combo box.
I am trying to fill a combo box using a dataset and data adapt. I am struggling too work out how to do it. I thought it would have been easy but I was wrong. i can set the text to read the first line of the colomn but nothing else. I was wondering if anyone could help me out with what I have to do. I think I have to increment inc and add a line underneath but I don't know how to do that
comboMaps.Text = datSet.Tables("TheLastShot").Rows(inc).Item("Maps")
i'm finishing up on my A2 Computing project now and am trying to make a few improvements. first of all, i want to fill a combo box with a list of variables from my database, so when they enter a new record on my vb form, they will have an option to choose from..
my attempt at coding:
Do
ComboBox.ObjectCollection.Equals(ds.Tables("TTDB").Rows(inc).Item("GroupID"))
inc = inc + 1
Loop Until inc = MaxRows
I'll start off with a brief explanation of my situation. I'm doing my A-Level coursework project at the moment and am having some difficulty trying to figure something out. My project is a VB.NET Program that connects to a Database to display/add/delete/update records. At the moment I am having trouble with one particular thing which must be solved before I can move on (and the deadline is fast approaching).
I have a combo box which contains a list of different item types (Which match up to the item types used in the database, but it is not filled from the database). When the user selects one of these options, the list box below must fill with all items of that type that are in the database.
Unfortunately I'm at home so I can't get access to my coding, but I can try to explain what I've tried. I've tried so many things after trawling though what seems like endless amounts of tutorials to find an answer.
One thing that is used in pretty much all of them is the SQL string to select the needed records;
"SELECT ItemName FROM Stock WHERE ItemType = Anime"
Now, this has been used many different ways. I think the way that I'm trying at the moment is to create a new data set that contains the records that are needed for the search. There is already a data set that contains the whole table that is needed for this particular form. I think my most recent attempt was trying to copy the relevant information from the original data set to the new one, but I can't get any coding that isn't incorrect.
Is there a way to make a DataGridView's column a combo ONLY in the "new row", and a read only textbox in all other rows? I want the user to be able to make a selection from the combo box, and when the row is finished and the "new row" moves down one, I want the column to become a textbox containing the what the user selected. My grid will be bound to a table witch contains a "category" column, that is drawn from a seccond table that i want the combo box bound to.
View 1 Repliesis there a way to set a single cell as a combo box? it looks to me that you can only set the whole column.

View 5 RepliesI have an access query which plays flawlesly in Access.I want to use it as a source for a datagridview i use in one of my forms but....given the fact that is a rather big query with some "like" and conditions like ">3" and so on AND the fact it uses tables from 3 different mdb (not to mention is bases on other queries...i 'ill try my best to fix this) what is the best approach .
1st case .Can i retrieve the data simply with NO oledbparameteres and NO " select * xxx where yyy like 'd' ".I think there is a issue with the Oledb connection that "omits" them.To explain better the query right now with the filters in access returns 3 rows, without the filters 30 rows,can i get just the 3 rows to do my job... 2nd case . How should i fill a datagridview using tables from 3 different mdbs.If you can show me an example it would be life saving.
I'm fairly new to VB.NET but have been programming for a while. Anyway, for the life of me I can't figure out how to properly populate a datagridview in .NET. I am using VS 2010. I add the control to the form, click the arrow on the control and select "add project data source". From there, I select Database, then Dataset, choose and ODBC data source, the table I want to use and enter the data set name.

I am working on a project that allows the user to search the database for particular records, then passes the record that the user chooses to the main form to be manipulated or changed. Yes I am aware that I could let the user change the values in the datagridview, but I do not wish to do that this way. This is the code for the event that fires when the user presses the button to return the selected row:
Private Sub returnBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles returnBtn.Click

View 1 RepliesI am struggling with coding up a bit of logic.
I have a map which I have created zones which are basically rectangles which have the coordinates sorted
eg
Zone 1
Zone 2
Zone 3
I then want to create circles within the rectangles. So for example
Item1, Zone1
Item2, Zone1
Item3, Zone3
Item4, Zone2
Item5, Zone1
So i would like Item 1, 2 and 5 to show up as three circles and when the mouse cursor floats over them to show it. The item list is dynamic and so I am not sure how to get about with this?
DataGridView inserting an extra row every time I populate with data. The row appears even if I only fill the column headers. This is causing problems when I try to get values of each cell. Is there a way to avoid this perhaps in properties?
View 1 RepliesI have written some code in a form which is shown via ShowDialog from a different form. This code fills a DataGridView with data from two tables in a dataset, one through data binding, and one through more manual means. The latter part runs, or more accurately, fails to run in the same way if I call this form in the same way subsequently but without stopping debugging.
