I'm using vb.net 2008 and I want to be able to format the way numeric values are displayed in the datagridview control.
My datagridview control is being populated from data stored in sql server 2008, what I am after is for a value to always show 2 decimal places, even if the number is a whole number. e.g. '1500' to display as '1500.00'.
I have already tried using the following commands in my sql statements:
CONVERT(MONEY, Value) AS Value
CONVERT(DECIMAL, Value) AS Value
But this doesn't seem to display correctly in the datagridview. for 1500 I get 1500.0000 and 1500
I am making a program that uses the datagridview control for making the sales invoice and I want to add direct values from textbox control to datagridview. But the problem is I am not getting the row, col index properly and if I use: dgv.item(0,dgv.rowcount -1).value=textbox1.text Then the value goes to the 1st col and 1st row. When I use dgv.rows.add() then value goes down to last row of the dgv control.
I want to multiply or add the values of two or more cells in a datagridview control in a row and and should also be auto-saved in the database after entering datas in the cell. I am using SQL Server 2008 for my database. do take a look at the screenshot attachment that I made for further details..
provide a simple example code for displaying a string array of (9x13) values in a datagridview control. I am lost in the complexity of data binding and datagridview controls. I am an experienced VB6 programmer and cannot seem to grasp the transition from flexgrid control to datagridview control.
I have some columns of my datagridview formatted as currency, set up in the designer. But after entering data, the values are not automatically formatted. Is there a setting I haven't found? Or is there code I can place in the cellvalidated event to get the cells to format properly?
My stored procedure covert two integer column Hours and Minutes to varchar data type and after concatenation the result looks like HH:MM (1:05).In DGV form I have problem to display same values. The EmpTime column is dispay time like (1:5). The column's coding is:Me.DataGridView.Columns("EmpTime").DefaultCellStyle.Format = "HH:mm".
I am using VS 2005 pro and VB.NET. How do you format the DataGridView.DefaultCellStyle.format property for zip codes and phone numbers. I have a zip code and phone number column(s) that I want to be formatted. I have tried a lot of different things:
Zip code: "99999-0000" or "Phone Number: "(999)000-0000" or "(000)000-0000" and the like So far nothing has worked. I can get my date columns formatted correctly, but not these. Can any one give me some examples that work?

I have a DataGridView on a WinForm that has a column with a combo box in it. The combo is populated from a datasource and all works great. My problem is this: How do I get the value selected (or the text) in the combobox for a specific row when a button is pressed?
I need to get all the different values from my dgv, but no duplicates, and add them as rows to my dataset.for example if my dgv col1 have the following values:
a b c
[code]....
the procedure must get the values from dgv1 and add it to a dataset if the values isnt already there.My dataset should have this:
i used a split container, in the 1st panel, i put the textbox for the user to input the values. In the 2nd panel, i put the datagridview to output the values that the user inputted. Now, i don't know and i cannot find way how to print the values into the datagridview from the textbox.

I have a DataGridView1 populated by sql searches. On the rare occasion that nothing is returned, my app cannot make use of data so I'm trying to check for null values. My code below is not correct because IsDBNull is not a member of the of the DataGridView1.
If DataGridView1.SelectedRows(0).IsDBNull Then MsgBox("Nothing to display") Exit Sub End If
I have a form which has a user control in it added dynamically. How can I change the values in that dynamically generated user control? All my functions are in a module and I will just call them in main form. So in module how can I find that user control and change its values? I tried writing a function in user control form. Like it has 10 txt box and I tried to pass a structure as argument in that user control form but I am unable to do so. when I tried to declare the structure outside function parameter in user control form it works well but not as function parameter..
I have 3 controls in my Form.Two Dropdowns and one textbox.My task is if i select a value in one Combobox then the related text should be display in other two controls.Ok I wrote a code in "SelectionChangeCommitted" event and now i am getting the values correctly.
So basically what I'm trying to do is write data from an XML file (a "save file") back into the form. My controls are in all different group boxes (makes it much easier for showing and hiding groups of controls dynamically). I thought about and am putting each control's Parent name into the file, but can't figure out how to get that parent name back into the DirectCast within a For...Next loop so it will actually cast the data into the control.
I bound datagridview to bindingsource. The bindingsource has its datasource a collection Called Rates which is a collection of Rate items. The rate object has a property called VALUE. I need the user to be able to edit different values for the collection; However, on the datagridview, i need to keep displaying on one column called OldValue the existing Rate value before the change while allowing the user to edit that value in a second column called NewValue.
In other terms, One colum OldValue will keep the existing values from the DB before being edited by the user, this column OldValue is readonly. Another column NewValue will display, the 1st time, the old value from the DB (similar to OldValue when we do the Fetch from the DB), but it`s editable column, so the user can modify each value in the column NewValue without overriding OldValue cells. For now, I bound both columns OldValue and NewValue to the same property VALUE of the Rate object,
I'm using a DataGridView in a Windows Forms application to update a table in my SQL CE database. The code runs without error; however, it appears that the database table is not being updated. I had this working at one point, now it is no longer working.
Private Sub BtnCommitChanges_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles BtnCommitChanges.Click If Me.CLCitiesDataSet.HasChanges = False Then Exit Sub 'Exit sub if no changes to dataset Dim SQLCommand As New SqlCeCommand("SELECT * FROM Cities")
Here is my problem: I have a DataGridView and I am adding a new row. In a particular cell, I have to check that the user does not enter existing values in the related table. That is, the value of that cell must be unique. If the user enters an existing value, the application must:
- Show error message
- Clean the cell
- Put the focus again into the cell, to allow the user to enter another value.

I've been asked by a local window cleaner to design a small utility that can display a grid of customer data, sort them, and then export it out as a formatted .txt or rtf file.
I am working on Datagridview. My task is adding buttons in the Datagridview table based on the case statements. Like In the Present table i have one column called "CategoryDescription". In this column, values are like 3101,3102, 3103........Here 31 is the common. and like 3201,3202,3203......Here 32 is the common. Like there are so many common values are there. So where ever the common values will come there i have to add one button in the Same column.
So Finally my conclsion is at Satrting 3101 and starting 3201,3301,3401.. i have to add one button control 3101 and add button control on 3201 and add button control on 3301.
how could I get the text of a specific cell in a DataGridView control ? If it matters , in my case , all the cells contain strings or nothing . For example , in order to get the text from the cell on row 2 and column 3 , what code do I have to use ? I have tried the Value property but seems that's not it . I've found some examples on the web ,but they were all for C# ... I guess , though , it has to be easy .
I need to convert hex values aa 01 00 17 f4 2f (as contained in byte array FrameData) to display in a label control as AA:01:00:17:F4:2F
HexDump(FrameData(2)) converts the aa (which has been converted to Decimal 170) into 31 37 30 !
similarly I need to convert hex data ('02 00' contained in byte array FrameData) as 0x0200."0x" & FrameData(1) + FrameData(2) displays the data as 0x20. How would I convert the '02 00' hex data to display as 0x0200?
