Field In Database Appear To Be Datagridview Header 2010?
Apr 10, 2011
how to make database field as datagridviewheader For example,I have table called subject, and have one column named subjectName. This column will hold all the subjectName, there are more than 100 subject names. E.G
subjectName: math,physics,chemistry,history
Let say a student take those subject, then how to display in datagridview something like this. (field in the subjectName appear to be datagridview header in datagridview)
I have been using this code to find the value of the cell in a datagrid view
Dim eRow As Integer eRow = dgv.CurrentRow.Index MessageBox.Show(dgv.Item(0, eRow).Value)
This works fine when the columns unless the user changes the order of the column.
So what I am trying to achieve is to find the value if the cell even if the order of the columns is changed. Is there a way instead of saying column (0, eRow) I can add (ColumnHeaderName = "NameHere", eRow) or something along those lines.
in my application i created table called houseloading which has field called housename.which is inserted into the sqlserver database. my table will look like this

I have used ADOX for create some fields in my database in access but the required property of this appended fields (columns) are set in "yes" but I want to be them "No" who knows how can I solve this problem
I'm using a MS Access 2007 database. I modified the field definition of one of the fields in a table, it a text field and I change the maximum length from 40 to 150. I have a data source in my app that contains this table and many others. I refreshed the data source but the change didn't take affect. I went through configure option but the change still didn't take affect. It gives me this error, The value violates the MaxLength limit of this column. If I add/delete a database field the data source is updated when I go through the configure process. I finally just deleted the table from my data source and then added it back.
There are lots of questions about this but I've not been able to solve my problem using the answers to any of them (after many, many attempts..)
I'm working in vb.net creating an asp.net web application. I have an SqlDataSource and a GridView on my page.
I want to change the DoNotMail boolean value represented by a Gridview checkbox and automatically update in the database if the checkbox is checked from 0 (False, Will Mail) to 1 (True, Won't Mail) here is the code I used. [code]...
is it possible to do a two way sync on the entire gridview when the user hits a button so you don't have to do an update every time a row is changed? because the user might check the box and then check another box then uncheck a box and it would be a lot of updates...
I created a local Database in VB2008 with 4 tables, the problem is that I have a textbox in one table and a combobox in other table and I want that the information that I put in textbox appear after in combobox from the other table... that's possible?
Table: Filmes ... Field: NomeTextBox Table: Tempo de Aluguer ... Field: Nome_FilmeComboBox
Dim query as String = "Select * from openquery (devbook, 'SELECT wb.arrival_time FROM web_bookings wb ')"All I need is to convert my arrival_time into a datetime field in the query
I have an application where a datagridview is used to display some data, a datatable is bounded to it, and I want to put some text in the front of some rows to indicate that they are different from others. My code checks the rows and used the following mydatagridview.Rows.Item(iCnt).HeaderCell.Value = "A" To set the row header values, it was fine when the data was first loaded. However, when I sort the datagridview by clicking the column header, these rowheadercell values disappear. How to keep the row header values after the sorting?
I am using following codes to format datagridview column headers, that works fine. My questions are
1) how to make all headings bold? (bold header row) 2) how to apply specific font to heading row 3) how to apply specific fontsize to heading row 4) how to apply specific fontstyle to heading row
With DataGridView1.ColumnHeadersDefaultCellStyle .Alignment = DataGridViewContentAlignment.MiddleCenter .BackColor = Color.CornflowerBlue
I am creating a DataGridView in code, not dropping the object on a form in the visual environment, and the row header is ugly. I have been playing around with this for a while. I would like the row header to look "normal", and it does not. The row header is slightly larger than the column headers, and the border is not showing. I also am not seeing the "*" or arrow(pencil) for current row selected.
Can I show checkboxes to the column headers in datagridview for each column in my dgv I Used [url] for help but it replaces the header cells one by one .Can I use any property of dgv which shows checkboxes for all column headers
I have a windows application with many forms. We use the DataGridView control on most of the forms, but on a new form that I designed I have four DataGridViews. All of the DataGridViews on this form do not dipaly the Column Header Text when the form is displayed when running in the IDE. I do not receive any errors or messages. The other DataGridVeiws on other forms display their column header text just fine. I am at a loss as to why this is happining on this form.
UPDATE: If I add the desired text to the column.HeaderText property at the end of the form load event it displays the column header text. For example AssignedAmountColumn.HeaderText = "Amount" it displays Amount in the column when run from the IDE.... However it dosn't display when the property is set though the Columns property at design time.
I have a datagrid and have added in some row headers:

However the row header width is very small and you cant read the header without adjusting it. What is the formatting command to automatically size the header to fit the text?
I am creating a database in VB.NET for a movie rental place. I currently have three forms;
Member Information DVD Information Borrow DVDs
What I would like to do is when I am viewing a member's details, if I click a button 'Borrow DVD for Member', the member's ID number transfers over to the Borrow DVDs table in the Member ID which also would hold some information from the DVD Information table, but I'm sure if i can figure out how to do this firstly, I will be able to apply the same rule and work it out myself.I have been trying to use a query statement like;
INSERT INTO [Borrow DVDs].[Member ID] [IN goodstuffvideos.mdb] SELECT [Member Information].[Member ID] FROM [Member Information]
but that has been coming up with error codes and completely not working.
Borrow DVDs table fields are: Borrow ID, Member ID, DVD ID Number, Hiring Fee, Borrowing Limit?
DVD Information table fields are: DVD ID Number, Title, Rating, Hiring Fee, Borrowing Limit Member?
Information table fields are: Member ID, Family Name, Given Name, Address, Town/Suburb, Postcode?
The error coming up is; Error in INSERT statement. Unable to parse query text.And under that it says The query cannot be represented graphically in the Diagram and Criteria Pane.
I'm looping through rows in a datagridview, and selecting a cell from the 3rd column each time:
Dim customer_name as String For Each dgvr As DataGridViewRow In myDataGridView.Rows customer_name= dgvr.Cells(2).Value '.... next dgvr
However, I'd really like to make it dynamic, in case a new column gets added to the grid, so that I need the 4th column, not the 3rd. I'd like to use the column's header text. So something like...
At runtime, I am adding a DataGridView to a windows form. The final column is a DataGridViewImageColumn:
Dim InfoIconColumn As New DataGridViewImageColumn MyDataGridView.Columns.Insert(MyDataGridView.Columns.Count, InfoIconColumn)
Adding the following code will get my Information Icon (bitmap) to display in each of the column cells but NOT the column header:
Dim InfoIcon As New Bitmap("C:MyPathInfoIcon.bmp") InfoIconColumn.Image = InfoIcon
Also, it is worth noting that the image displays 'perfectly' in the cells i.e. it is sized correctly to fit the cell.
However, I cannot find a way to add the same image to the column header cell. After some googling I used the following code which placed the image in the header cell but left me with two problems:
The image did not 'auto-size' to the column headercell in the same way it did when added to the column cells. The image was slightly larger and blurred. By using the _CellPainting event slowed down performance i.e. when hovering over the DataGridView to highlight the selected row the highlighting lagged behind where my mouse was placed.
Here is the code:
[Code]...
Does anybody know of a way to solve my problem and get a nicely sized, sharp image into a DataGridViewImageColumn headercell at runtime?
I'm trying to render a checkbox in a datagridview column header so that when the checkbox is checked/unchecked all the cells in that column should be checked/unchecked accordingly.The datagridview is bound to a database table but the column containing the checkbox header cell is unbound. The problem is, whenever i click the header checkbox, all the cells in that column are checked but the header checkbox itself gets invisible. If I click the HEADER (though the checkbox is invisible, still I can click the header) again, all the cells in the column below are unchecked and the header checkbox becomes visible and unchecked. Everything is happening as expected except the visibility of the header checkbox. Why is it so?
''' <summary> ''' The custom class for checkbox header cell. ''' </summary>
