View 7 RepliesUsing SQL Express 2008, I have tables with the following columns[code]...
View 7 RepliesIt seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?

I have a datagrid that I am unable to change the width setting, it always reverts back to the original setting.
To change this setting:
1. select the datagrid view tasks
2. Edit columns bound column properties
3. Select Width property
4. Width property will always revert back to the original setting.
I have check the properties settings without any luck.
It appears my connection to the db is correct when I select different options the datagrid displays the correct number of records. So I am not sure why I can not see the data in the grid.[code]....
View 4 RepliesI am attempting to display a datagrid with the results of two different queries. I want one to display, wait two minutes,display the second query, wait again then start over. I am unable to get either grid to display. If I run either query individually without the wait they display perfectly. How can I do this?

Take text data from a small file and display it in a form using a DataGrid.
I am trying to make the program so it will allow the user to choose which file to open (this part already works). I have stepped through the code and found that the rows are being added to the table, but when the action runs to completion my form has no data on it. Here is my code (forgive any code shortcomings as I have exactly three days as a VB.NET programmer).

I am trying to display an excel spreadsheet on a page using datagrid, but for some reason it is filtering out some of the cells, leaving a blank space instead. Also, the "$" sign won't show up in most of the columns.Could someone please take a look at my site and file, and give a suggestion as to why this would be happening? I've tried a bunch of troubleshooting on it, with no success.

I have populated a dataset with the contents of a csv file. Here is a sample of the imported data:
Protocol,Process ID,Process Name,Local Address,Local Port,Remote Address,Remote Port,Status
TCP,4,SYSTEM,134.190.220.54,4505,134.190.184.193,139,ESTABLISHED
TCP,4,SYSTEM,134.190.220.54,3963,134.190.218.5,139,ESTABLISHED
TCP,4,SYSTEM,134.190.220.54,3816,134.190.176.154,445,ESTABLISHED
Here is the code that I used to import and display the data:
Code:
Dim sConnectionString2 As String
sConnectionString2 = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" _
& CasePath & ";Extended Properties=""text;HDR=Yes;FMT=Delimited"""
[code]....
The problem is, all of the data gets displayed correctly except for the ip address. It gets truncated to "134.1892". How can I change the formatting for the "Local Address" and "Remote Address" columns.
I've tried a few different methods I could find in order to connect my VB .NET program to a book store's database. While I've been able to connect to it and display the contents of its tables in a DataGrid, I need to be able to search the tables and display specific records, depending on the contents of appropriate the adjacent text boxes.[code]This is a code I've used for a very similar process, just really aims to search a different field in the table. If this is easier to adapt into a code that allows searching and producing specific records in a database, please use this one.

I have 5 textboxes embedded in a datagrid that require a date format (mm/dd/yy), but can be left empty if user doesn't have date.User can poplute these textboxes for multiple records and hit submit button.On the submit i loop through the grid. If dates are populated AND they are in the correct format then I call a stored procedure that inserts the record into a table.If any of the dates that are populated in the textbox is not a date or in the incorrect format I need to display error message in a label.I got all this to work, but if it throws error message all the data in the grid is wiped out.How can i keep data in each textbox and still display the error message?

View 2 RepliesI have a gridview that is bound to a datasource on a Windows Form (VB.NET). The grid displays a list of "certifications", and each "certification" can be associated with many languages. So in the grid, I'd like to display "languages" as a column, and display a comma delimited list of the language names for each "certification".
In the "certification" class, one of the properties is a list of "language" objects, and each "language" has an ID (guid), name (string), and value (integer).
So in the datasource, I have the list of "languages", but I can't figure out how to display them in a column on the grid. The gridview won't let me add the language list property as a column.
So is the ONLY way to add a new property on the "certification" class, which returns a string that contains the comma delimited list, and show THAT on the grid? Or is there a way to display that list of "languages"?
