I want to make my checkboxes to work as a filter for my DataGridView. The checkbox.text is the thing I wanted to use for filtering.My problem is that, when I click on the button with one or more checkboxes checked, my datagridview shows no data. (Of course, before I pushed the button it did).
[Code]...
My problem is once I filter my datagridview I cant seem to be able to update the database. The error I get is Concurrency violation: the Update Command affected 0 of the expected 1 records. Why is it that I cant update after i filter????
View 1 RepliesI have a DataGridView that is bound to a datatable. I also have a combo box with sorting items in it. When the user selects a new item in the combo box, the DataBindingSource.filter is changed accordingly.
For the cell and row validation on the DataGridView, I set the row error text accordingly as opposed to displaying a message box.
Occasionally, when switching between items in the combo box, the datagridview gets filled with a bunch of empty rows that all have error messages. It seems it is validating the rows that existed from the previously selected filter against the new filter.
See attached image. I hope I am making myself clear.
[code]I want users to be able to click on the checkbox in field4 and add all of the data plus the word Holiday to my database when they click on the box in that field, but right now it's not allowing me to click on the checkbox, can someone please assist? Also, I did have this working for that field but it would only allow me to add the first line of data, what in my code would not allow for the additional lines to not add their data as well?

I have some DataGridView code written in vb.net.

It even turns ON the checkbox in rows other than the row I clicked in. (Huh?)

I am currently developing a program that was first built within access using VBA.My program is a search form connected to an access database, which is itself linked to a dbf database.I managed the code from access to a new program, but I am stuck with one line of code;How can I open a form (which shows the filtered data) using a filter (a string built with the input boxes).
The code in vba is:
DoCmd.OpenForm "frm", , , Left(strWhere, lngLen), acFormReadOnly
where FRM = the form showing the data
strwhere = SQL string
lnglen = number of characters in strwhere.
How can I do the same in a Visual Studio 8 environment (Visual Basic -idontknowwhat-) ?
Could not find this through Google or in SO questions.I have a checkbox listbox on my form. I want to filter my List by the list of selected Ids from that listbox that are checked, in SQL I would have done this like "Where TypeId In (1, 4, 5, 7)"... how do I do that in LINQ?
I feel like I am missing a really obvious answer, but cannot get it.
For argument sake... here is the what I have for sample data:
In Colors (List<of currentColors>)
ID, Name, TypeId
1, Red, 1
2, Blue, 1
3, Green, 2
4, Pink, 3
Selected Types 2 and 3 in CheckboxList: filteredColors

2) I have a column in my datagrid that I have changed to combobox and I did two things both gives me this error, first I inserted the values for the combobox in the collection. Second, I connected to one of the tables with a binding source and has one of the columns as the options (advisors).
Each student has a different advisor so the field gets set to the correct advisor each time but the problem I am getting is when I scroll (doesn't happen for a little while) I get an error so i put in this sub to handle it and the error message box says: Error Happened Formatting, Display.

I have a DataGridView (dgv) on a Windows form (VB.NET) which is bound to a datatable. One of the bound columns is a an ID (Foreign Key) to another datatable. All I want to do is Hide the ID column and populate an unbound column with the Name (ParmName) for the user. I searched the foreign value in the datatable and retrieved the information. I set the Value of the cell in the Datarow. All works well, but does not display. The cell accepts the value...I can even Debug.Print the values to the console. They are there just nothing displaying in DataGridView. Nothing odd about DataGridView. Should be straight forward...

I'm adding textboxes inside a datagridview to use them to filter the data that is displayed in the grid. Each column has a textbox placed in the header. Everything is fine until the grid has the horizontalscroll visible. The texbox move if the scroll isused but they flicker and if the grid has the rowheader visible the textboxes gets over it. Is there any way to avoid the flicker and a workaround with the rowheader. I don't want to have to hide the rowheader but if there is nothing else that can be done.The class is not finish yet:

I have it so when the form loads I can double click and the row and bring up the form to edit that row. This works. but if I run a filter on it and then double click it doesn't bring up the selected row but the first row of the grid as if I never had a filter on it. I have 1000 rows, I run the search to filter it and find 5 rows. I click on the last row and it brings up the data from row one of the 1000 rows. Always the top row. Does this have something to do with the bindingsource not having the correct index?
