I am totally new to VB and ADO. I know that we can bind a data source to the datagrid view but if I want to populate the same datagrid view with different set of data but the column names are the same. Based on a date range entered by the user I would like to populate the datagrid view. Can we do this at design time? If I not how do I do this?

I have a Datagridview, It will have pairs of lines:
first line: requested customer
second line: assigned quantity for that item for that customer
Something like:
CUSTOMER-ITEM-VARIATION1-VARIATION2-VARIATION3-VARIATION4
Cust001....-120.-......10........-.........0.......-........8........-.........1
Cust001....-120.-........0........-.........0.......-........0........-.........0
Cust002....-120.-......15........-.........7.......-........2........-.........0
Cust002....-120.-........6........-.........0.......-........1........-.........0
The second line will have numbers if other table has information about that customer reservations, or will be in 0 if not.I can load the first line of each pair, with the data of the "requested" items loading a datagrid with a datatable.
somehow combine the results of separate Fill queries on a single dataset?Basically, I'm trying to implement a 'Filter' function, whereby, the user can filter the records in a DataSet according to specific criteria.

I am developing a report which outputs data in a SQL Table via an ASPX page, using VB. How do I code this so that all rows containing a "1" for one of the columns, shows up as red? Here is what I have so far. This doesn't cause any errors, but it doesn't show up as red either.

Depending on a preprocessor directive, I want to set all properties in a class to EditorBrowsableAttribute.Never.

I am developing an ASPX file to return all records from a SQL table. I can successfully get all of the numbers to show, but now I want certain rows to have their background colors changed if they meet certain criteria. So I want to compare 2 of my columns to some value, and if it exceeds this value then it should change color of that row. How can I fix below code? Main problem is I don't know how to specify a column of data to compare. No errors on this, but none of my rows have color changes either.[code]...

I am trying to fill my DataGridView using a date for my parameter. My first problem was in my code where I would get the common error message of Too many arguments to public overrides overloadable. I solved that error message by going into the dataset designer, selecting the query and adding RegDate as a parameter. Now my problem is that I will enter a date in my tool strip text box click the button and still get my data grid view filled with all the data.
Try
Dim RegDate As Date = CDate(RegDateToolStripTextBox.Text)
Me.PatientsTableAdapter.FillByDate(Me.Database1DataSet.Patients, RegDate)

I am using VB 2010 with an Access 2010 database. The Access table is the data source for a DataGridView created by dragging the table from the DataSet onto the form. The table has 3 columns - First, Last and DOB (Date of Birth). I want to have a column in each row to show the person's age. I added an unbound cell in the DataGridView called Age, but cannot figure out how to fill the cell with the information I need. I tried using the DataName property, but that will only allow me to enter columns already in the grid. I think what I need to do is fill this cell (Age) by a value computed from DateDiff(DateInterval.Year, DOB, Now), but I cannot figure out how to do so.

how to load data into datagridview using backgroundworker & progressbar?Let's say i have a report that shows some statistics, or has 100 000 of rows that should be displayed and during the load i would like to show the data that is already loaded and not to frees the form.Same example like in SQL when you perform a select command from a table which has 100 000 of rows and while loading the data, the grid is already filled up and progressbar is shown at the left buttom side.
View 7 RepliesI have a database with values as shown in the attached image "Image1.jpg". There are multiple other columns not shown on the screenshot (over 30), for the sake of this question we'll say I'm interested in columns called "Col1", "Col2", "Col3" & "Col4".
I was able to get this information automatically filled into a TreeView as shown on attached image "Image2.jpg".
At this point I also want to fill a DataGridView from the same database.
I managed to accomplish this with the following

But unfortunately this uses the manual binding of data to the DataGridView, which I'm sorry to say I struggled to "convert" if you like, to using SQL commands and coding to connect a database to DataGridView.
I have a datagridview with 3 columns.
Now I need to fill the datagridview's datasource with 3 arrays.
