I have an unbound Gridview that is populated by a Linq to Entities query and would like to convert string values in a particular column to lowercase. In the Gridview's RowDataBound event, I have tried StrConv(e.Row.Cells(3).Text, VbStrConv.ProperCase) but this doesn't work. I have also tried StrConv(emp.Name, VbStrConv.ProperCase) in the LiNQ to Entities query but still the Name values returned are to converted to Lower-case.

I have a Datatable with one column of the table being 'PartNum(product part number)'. I used EntriesTable.DefaultView.Sort = "PartNum ASC" to sort the whole Table, with respect to the information in this column. Now I'm just trying to further sort the table by grouping rows that have same info under that column together and do something to each of such groups. but I'm kinda stuck here.
I'm thinking of creating some sub-DataTables out of the original one and have these sub-tables to hold those rows with same info under "PartNum". Does anyone have ideas how to do that? maybe with DataReader or DataView ,

How, if it's possible, you can make a combobox have groups like the html example below:
<select>
<optgroup label="Swedish Cars">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
</optgroup>

VB GridView control will not allow code in the vb code file to access a data column that has its visible property set to false. When it is set to true, the data column can be accessed with no problem. Any suggestions as to how to correct this? I have looked through the documentation, text books, and I have not found anything that gave me any clue as to what the problem could be. I thought that the property was just applied to the column, not that it would remove the column from being accessible.

I'm writing a help application for the Customer support team at my company to help agents ask better questions when customers report problems. In it, I've got a SQL database that contains all the products, topics, and questions. The layout is similar to the following:
Products Table:
Product_ID Product Name:
Topics Table:
Topic_ID Product_ID Topic
[code]....
I don't know if I'm making myself clear, but I basically need to do the equivalent to the following SQL statement: "SELECT PRODUCT_ID FROM Products WHERE PRODUCT_Name = LstProducts.SelectedValue"

I have a data gridview on my windows form with 4 columns. Now I identify a column as followed:
Dim item1 as String = DataGridView1.Item(1, index).Value
So now I use a number ( In this case: 1 ) for the column index, but I want to make it a bit more readable so now I want to obtain the column index based on the datagridview column name.[code]...

I have a grid view which uses SQL to calculate information that I need! I want to put this calculated total into another table in database.
SELECT StaffDetails.StaffID, SUM(HolidayRequests.RequestTotalDays) AS Expr1
FROM HolidayRequests INNER JOIN StaffDetails ON HolidayRequests.Username = StaffDetails.UserName
[Code]....
It basically calculates the total number of approved holiday requests for a staff member which is correct. I want this number to then update the HolidayTaken field in another table each time a holiday is approved.
I have tried an update however you cannot use an aggregate in an update as I have found.

What I want to do is basically have a column that ranks the users so if there were 10 people it would rank the person with the highest sales 10 and the second highest 9 and so on. Theres not always going to be 10 employees
I am using a stored procedure along with a sqldatasource to connect to my stored procedure. To get all the data for each agent, then I am using functions like
Dim TotalSales As Decimal = 0.0
Function GetTotalSales(ByVal Price As Decimal) As Decimal
TotalSales += Price
[Code]....
and then some how sort the array list and print the index of the agents sales total?

I have a GridView with a button located beneath it. The GridView's height is set dynamically. When the height is set, it displays on top of the button. What I want to do is move the button down so it still displays just below the GridView when its height is changed.I know I can just set the location of the button, based on the height of the GridView, but is there a way to link the height to the location of the button? Like anchoring the button to the bottom edge of the GridView.

[code]If I wanted to get Part Name for multiple PartIDs from OrderDetails, how would I go about doing this? Would I use two DataTables? I'm confused as I cannot see an efficient way to do this. The only thing that I can think of is to create a DataTable with SQL:[code]and then maybe use a For loop to take each PartID, create another DataTable to find the PartName for that and then give this to a variable. There could be up to 10 PartIDs to search through and I don't want to have variables such as PartID1 PartID2 etc. [code]
