How do we set width of individual columns in data grid ?
View 4 RepliesI need to split an Arraylist into individual columns, here is an example of a column in the arraylist:
John Doe - John.Doe@email.com
I want to split up the arraylist so I can use the name and the email address in an email routine i.e. Dear John Doe, yada yada
I need a few columns in my datagridview to have the font be aligned to the right, but no matter what code I use it doesnt work.
I would also like my columns with numbers to always have 2 decimals.
And lastly I would like the right side of the column header to be blank and not movable. I can do this by adding another column to my table with a blank name and then set the width to fill, but the problem is I can just move this around, which is not good, I want to freeze it so it looks good. I do want to be able to move around on the other columns, just not this one. Unless there is another way to do that?
I am currently using a recursive search to get all of the files in a directory as well as in all subdirectories of that directory. At the moment (as a temporary solution to make sure the script worked) I have all files with their respective directories listed in a listview (2 separate columns).

I am having a problem regarding to Importing file from excel to listview. Actually my problem is that my program will let the user define what database he/she want. I know already how to load on my listview from .txt, access, ms sqlserver, but my problem is the user want to open from excel file. Base from his data, the columns contained Contact, address, age,name and only in sheet1. My problem now is that the user want to call his/her excel act like a database. The tablename will be Sheet1 and if he/she want to display the age and name column he/she can view by calling the its columnname. The columname will act as a fieldname. How can I do this upon loading all of this to listview. I have here an example on how i load data from .txt(csv) format but i need an excel on how to load data coming from excel.[code]...

Now that I figured that out I was going to try and place the data in a specific location. On my application I have a datagridview set up with 4 columns. What I would like to do is put column A of the excel file under the 1st column of the datagridview and column C of the Excel File in the second column of the datagridview.
So replace:

With:
vb
DataGridView1.columns(0) = myDataset.Tables(0).columns(0)
DataGridView1.columns(1) = myDataset.Tables(0).columns(2)
Obviously this doesnt work, and something tells me I might need a for loop to import the data, but I have never imported information from an Excel file before and to make it worse I have never worked with datagridviews before so I have no idea how to go about this.
I would like to do something like this if I could:
vb
For x = 1 To xldoc.rows.length - 1
DataGridView1.Item(0, x).Value = CType(xlDoc.Cells(0, x + 1), Excel.Range).Text

In my application I read data (using data binding) from an Excel spreadsheet into a DataGridView. This works, but the data columns contain text fields (strings). I would like to set the data type for some columns to "Date" and Decimal. I cant do this on the DataGridView (error: cant change properties for data-bound stuff) and I cant figure out how to do it on the dataset or data-table that I bind to the DataGridView.The following is the code I use to read and bind the data:

View 2 RepliesI have an access database with one table and 4 or 5 different fields.
All I need to do is be able to be able to use a loop to read the values in a specific row and column and store it in a variable (or array).
I don't need the code for the loop or anything, just the syntax for reading the value of a specific row and column in a table to a variable.
I have a unbound datagridview which i use to enter data. I would like to make calculations using individual cell data as follows:-
Datagridview1.rows(0).cells(1).value = datagridview1.rows(1).cells(1).value + datagridview1.rows(1).cells(2).value
This works fine but if im using lots of cells it can be quite confusing .I was wondering if there was a way that i can give a cell a unique name so i can be easy for me to identify. Using the above example it could read TOTAL = JAN TOTAL + FEB TOTAL
I have datgridview with 12 numbers of rows. I set the format through collection like
Format= N2 but i want row number 5 shows four decimal places instead of two? How i set it?
I have never worked with datagridview before. I need to know how to use it so i can use it in my (calculator) program. I would like to know how to make columns, rows, linking the cells in the table/grid to textboxes so values entered into the textboxes (on the calculator) after pressing save goes straight to the table.
View 1 RepliesIs it possible to take an Excel spreadsheet and move some columns around? Basically I receive spreadsheets that need to be re-formatted and have the columns shifted, some also need to be deleted. I have no idea how to go about this, is it even possible? It's always the same columns so it's not like it changes from file to file. I know it probably makes more sense to just create a macro but I thought I'd see what was involved in it anyway.

View 1 RepliesI am trying to create a .Net application to edit a excel file by deleting some columns and keeping the columns which we need and then removing the duplicate values based on the first column which is going to be the Serial no. which should have a check to have 6 digits by default like 2563 should be displayed as 002563.
Code:
Public Function GetAllFileContents(ByVal path As String, ByRef errorMessage As String) As IList(Of String)
Dim contents = New List(Of String)
Try
Dim files = Directory.GetFiles(path, "*.xls")
If (files.Length = 0) Then errorMessage = "Please select the files"
For Each file In files

I am trying to create something different by not only letting me do it for excel files but for say txt and csv files along with it. Removing all the values which I dont want and removing the duplicates and then if possible putting a check on the first column of data that the serial number number should have minimum of 6 characters and then The output file should have all the details in Uppercase
I am reading XLS files, via JET provider, using the following

cn.Open()
da = New OleDbDataAdapter("SELECT * FROM [" & sheetname & "]", cn)
da.Fill(dt)
The problem I am facing now is that some of these excel files have hidden columns: These columns are meant to be ignored. However, the code above fills my datatable with ALL columns (hidden and nothidden). Is there any "Extended Property" that I could add to the connection string, to ignore hidden columns?
