VS 2005 Datagridview Sort Not Working / Wrong Filling Cells?
Nov 8, 2011
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?

I created a DataGridView and entered some data in it,at runtime it looks like this:Attachment 72177Here the 3rd row name column cell is a bit short according to the name size....so i want to increase the cell size at runtime such that the user can see the full name.....Again the roll and age cells are a bit short.....so i want to decrease them as well..
I tried this with the AutoSizeColumnsMode and the AutoSizeRowssMode but in vain...How to do this?

I've got a DataGridview I want to remove columns from as it greatly increases performance when I format the DGV. The first time I remove columns in a loop (using the removeat) property, everythings fine. But when I try to remove more columns in another loop, it appears to remove the wrong columns and displays the wrong data. In other words, it displays the wrong data and headers; and the columns it does show has headers and cells that don't match.

how to sort the Datagridview. In my scenario I've a datagridview and this is the code I use to fill it:
vb
...declaration of cmdStoredProc...
cn.Open()
cmdStoredProc.ExecuteNonQuery()
[code]....
So it works very well only if i set AutoGenerateColumns = True.Why this code doesn't work with the autogeneratecolumns property set to false and the runtime binding of each column?

I have some code written by another developer(no, really). The datagridview has the AllowUserToResizeColumns property set to true, but at runtime the grid will not allow column resizing. I've checked the code to see if the property is being set in code and I can't find anything. Is there some other grid property that, if set to a certain value, will disable column resizing?

Was updating a project and all of a sudden the auto-filling of a WebBrowserControl's Dropdownbox stopped working. Here is the HTML of the Input box:
[Code]....
I think it is the "onkeyup" thing that isn't getting fired properly so the dropdown list isn't updating itself... it was working fine before, and now, with no changes, it just stopped working. can someone take a look at my code and see if they spot anything? EDIT: attached an image of the dropdown box in question. as I type, it does the lookup. (using the onkeyup event). I am setting the value of the dropdown to the five digit code at run-time, trying to trigger the onkeyup event to get it to get the full line, but it won't work.

In a gridview, the sorting event you can do a

.DataSource = Os

This is my first time posting here although I have been lurking for quite some time. I'm stuck with a problem I have seen before and never solved: I have a long list (~23,000) of alphanumeric strings that I'm reading into a List(of String) from a text file, and then sorting. When I iterate through the list after sorting, it appears to be correctly sorted EXCEPT that the element that was originally at the beginning of the list is now at the end (and it should be somewhere in the middle after the sort)Here is a sample input:
PRE1-PRE2_00015648
PRE1-PRE2_00015649
PRE1-PRE2_00015650

I have a slightly odd problem that I think is most likely due to an act of foolishness on my part, but for the life of me I (and other members of my team) can't see it.I have an object that contains a generic list property which I would like to sort. I have written a comparer class to do this for me and I am calling it in the following way:baseObject.ListOfThings.Sort(new ThingComparer()I have debugged into my compare function and it is returning the right values.However After the sort call, the list remains unchanged. Have I missed something obvious, or is there something else I need to do.EDIT: Yes I was being a fool, and the property returning a list was recreating it from scratch each time it was accessed

I have a program that is connecting to an oracle database. I am using the table adapter to fill a combobox to select a model. Then I am connecting to the database programically to return a max and min value based on the selected model. I am doing this by passing parameters back with the selected mode. This all works fine.

I've tried google a way to sort a table but couldn't get my code working.My program lets the user input enter information such as first name and last name in textboxes, once done they click on update button(so far everything works).On the top right of the form it has a Combobox and it displays a list of all the names of poeple the User inputed... but it shows it in the order the user inputed.I want to have a sort button so that way when the user clicks on "sort" it will alphabetically sort the msql table by last name and reupdate that on the Combobox (most importantly save msql with the new order of names)

I 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
Dim ActRow As ds.ActivityRow

I 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?

I have this database and I need to load it with a visual basic form in Visual Studio 2005.The database has 6 tables and they contain wrong data that I must filter when loading the database in the form.
A quick example:First table is Category, which has 3 fields (id, name, description). In one record I have 2a for id (a numeric only field) and in other record I have m1lk for name (a string only field).
When I click a button I load the database into a DataGridView control. How do I stop visual basic from loading into the DataGridView control those records that have invalid data (like in my example).
I have try with SQL queries using WHERE and LIKE, like in
SELECT IdCategoría, NombreCategoría, Descripción
FROM Categorías
WHERE (NombreCategoría LIKE '[!l]%') AND (IdCategoría LIKE '[!abcdefghijklmnñopqrstuvwxyz]')
but it's really difficult to filter things like Angel* and P3ter and Hood8, all at the same time..
