Filter Expression For Use With Button?
Apr 28, 2011
Is it possible to have a filter expression invoked when a button is clicked. The only documentation i can seem to find is based on a dropDownList. For example;
<asp:SqlDataSource
id="SqlDataSource1"
runat="server"
[code]....

I am trying to build a filter string for my DataView, but I have run into a problem. My underlying DataTable contains values that are formatted when displayed in my DataGridView.For example, if the DataColumn contains 1.52 and the DataGridViewColumn.DefaultCellStyle.Format = "n0" then 2 is displayed.So the user sees 2, then sets the DataView.RowFilter = "DataColumn = 2", and no DataRows are returned. Is there a way to format the DataColumn in the RowFilter string? For example, DataView.RowFilter = "FORMAT(DataColumn, "n0") IN (2, 4)". This filter string should return 3 rows. If not, can LINQ do this?

I am trying to filter the results of a datagridviw using the bindingsource.filter method.
Dim filters(2) As String
...
If Me.txtPartIDFilter.Text = "" Then
[code]....
The issue is in the last line. ID_Part is an Int64 data type filters(0) is a string so the system returns a "Can't perform 'Like' operation on System.Int64 and System.String" error message.As you can see I tried converting the data type, but that failed since it is encased in String.Format()- it's going to be a string no matter what, I suppose.It's almost 1:00 a.m. so I'm not firing on all cylinders.

While looking in the dataset designer for a database table I am doing in visual basic 2008 I found a line for expressions under the property menu for a specific column. I need to know the code that I would put in this expression line so that this column adds up the numbers I input into three other columns and displays that number in the column. I need it to automatically calculate this for each row in the database table.

I am using Flee to build a formula builder. It works great but the only problem I'm facing is that Flee doesn't understand Generic Methods I guess. I have a function called IIf declared in the expression context I'm using. [code]How can I work around this. I mean cannot , in sense, write all possible overloads of the function of all .net primitive types. What approach should I take.

I must convert string data from a CNC that is arithmetic expression to a number that I can use in a VB application that I wrote. The following is what I get out of the cnc. [18722*65536+19377]/67108864. I need to evaluate this expression in my VB ap. The format of the string is not always the same as what I have illustrated.

I'm having some trouble extracting a distinct value out of a dataset.. I have a database table with 5 fields,
ProjectName, VendorName, ExpenseType; TxnDate; Amount
In VB6 I would have several different recordsets opened one after another to
A. Find all the unique project names within the table (and put them into a For/Next loop)
B. For each unique project name open a recordset to look up unique vendor names applicable to it (add For/Next)
C. For each unique projname, unique vend combination find unique exptype....for next loop....
D. For each unique projname, vendor name, exptype, date combination, sum up the dollar amounts...
The end effect is that you have a net dollar amount for each unique combination of project/vendor/expensetype/date.I dont like doing it like this because I have to keep hitting the database, I wanted to know if there was something I could do within the actual dataset which will be filled when I open the application with the values of the entire table..I got to ds.tables("Text").select.distinct( ....not sure how to proceed and everthing I've read online leads me into a complicated direction of creating new datatables...
