Use Rowfilter To Filter Year?
May 15, 2010
I'm trying to filter a dataview for e.g dates with a year larger then 2005, or e.g items with a month+year larger then Oct 2005. The compared to value comes from a datatimepicker which depending upon users input has a custom format of either full date, month+year or year as its textproperty.
I know that rowfilter is very limited in its options, and that's where my problem lies.
The dates in my dataview are real dates, M/dd/yyyy, so no conversion needed. The date columns type is also DateTime as such. The problem though is that I'm not able to separate the year, or month+year from the date columns value to compare against the datetimpickers value.

I am trying to use dataview.Rowfilter to filter datagridview for users. The basic idea is that user enters a text in a textbox, and then the below function is called to filter the text in all columns, like Col1=value OR col2=value OR col3=value. But I got error message of the filter expression.

I have a datatable and I apply a filter to the defaultview.rowfilter property of that datatable. If I then loop through the rows collection of the datatable, will I only be able to see those rows that the filter applies to, or will it loop through all the rows?

I'm using EPPlus to create Excel reports. Now i'm trying to create a Pivot with a DateTime PageField, so that the user can filter the period he want to see by himself. But although i can filter this for year,month or days in the according data worksheet by default, i don't get it working in the Pivot.
Here is what i have:
Dim wsPivot = excel.Workbook.Worksheets.Add("Pivot")
Dim wsData = excel.Workbook.Worksheets.Add("Data")
Dim source = workSheet.GetDataSource

Is it possible to select distinct in the rowfilter method?
I have something like:
VB
'Create a data view so we can get each items name
Dim dvwItemNames As New DataView(dtlItems)
dvwItemNames.RowFilter() = "SELECT DISTINCT Name"
This gives me a syntax error exception. I tried just "Distinct Name" but this had the same result. "Name" is the column name. I would rather do it this way then looping through the entire table and putting the name in an array list or something.

I can filter when I'm only checking with one textbox, but when i try to use multiple text box filters its does not work the way I want it to. I understand what is going on here but i don't know what to do to fix it. Basically I have my main form with the datagridview, there is a button on this form called filter. When the user will hit this button a small form will pop up with 5 text boxes, I want to give the user the ability to enter into any text box they wish and the datagrid view will update accordingly.The problem is when they enter into one text box it works fine, but when the try entering into a second test box the filter is only filtering from the original datatable and now the dataview.
Code:
Public Class Form2
Dim dvFilter As DataView

Does anyone know if it's possible to pad a column to the left using the RowFilter property in a DataView? My data comes from a third party via XML which I've converted to a DataSet. I'm inferring the XML schema to set the column datatype. I've converted the column in question to string in order to properly compare any text entered by the user. At the time I populate the data grid I format the column by padding it with zeros on the left side so that it is always 11 characters (Ex: 123456789 becomes 00123456789). This is for legal reasons and not optional. However when using the RowFilter property the zeros in front are obviously not accounted for because they don't exist in the DataSet.
This is what I'm doing currently:

I have a dataset that holds a few tables; Songs, Artists and SongArtists (relations between songs and artists). I want to bind a grid to a view of the songs so they are filtered by artist. A combo will provides the artistID. Is there a way to use a dataview.RowFilter to filter based on a table that the dataview is not "viewing"? Or is there a better way to do this type of thing?

why the rowfilter property does not work if there is an apostrophe in present in the string. For e.g. , tempdat.DefaultView.RowFilter = "Mystring = '" & st & "'" the above does not work if st="mystrings's" under the column header Mystring.

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.
