View 2 RepliesDoes 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 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

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.
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 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?
View 2 RepliesI 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.

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.

View 1 RepliesI'm trying to sort multple colums in the DataGridView which is unbound. I would prefer to sort by using a DataTable/DataView but for some reason another developer in my team experienced other problems relating to sorting so he abandoned using the DataTable to fill the grid :(
Here is the senario: I want the user to be able to choose which columns they want sort on. The way I envisaged was to show a form with a listbox, a grid and 3 buttons (Add to sort, Remove from sort and Apply Sort).
The list box would be populated from the parent form grid column headings.
The grid will show the columns and sort direction.
Button 1 would add the selected item of the list box to the grid.
Button 2 would remove from the grid the selected row.
Button 3 would Apply the Sort in the order of the grid and the columns SortDirection.
Now I looked at How to: Customize Sorting in the Windows Forms DataGridView Control using the IComparer [URL]
how I can use the IComparer to sort on multiple columns that a user has specified or another way to sort on multiple columns using unbound data.
How do I combine the following two similar statement into one. They are similar in the sense that they both get input from the same textbox:
Me.ReportsQueryBindingSource.Filter = "ParkingSpaceID = '" & txtSearch.Text & "'"
Me.ReportsQueryBindingSource.Filter = "StudentID = '" & txtSearch.Text & "'"
I have tried couple :
Me.ReportsQueryBindingSource.Filter = "StudentID = '" & txtSearch.Text & "'" Or "ParkingSpaceID ='"& txtSearch.Text & "'"
Me.ReportsQueryBindingSource.Filter = "StudentID Or "ParkingSpaceID ='"& txtSearch.Text & "'"
......just none of them works...

I have downloaded the VBWinFormDataGridView from the code framework, and implemented the code in to a project the only problem i have found is when i refresh or reload the information in to the column headers it increases the size and keeps doing this so the column headers take up the full form height.i understand that the coumn header height needs to be reset but unsure how to do this.

View 9 RepliesI need to create a checkedlistbox that has multiple columns and each column has a header. Is this possible? I can't really find much on Google. Here's the headers I need:
Checkbox Title Existing path Destination path
I have created these columns to the checkedlistbox I have in my form, but when it is run the headers don't show up. Also the items I'm adding don't seem to abiding to the column widths I put in. Also with the code I'm providing below the items don't display as multiple rows, meaning each item doesn't get displayed on a new row, but in a new column.

Movie = New MovieItem()

With my query an exception is generated saying that @booking_date has already been declared try a different variable....

I have a table with two columns, date and time. I am using the following code to sort in descending date order.
VB
If historydataGrid.Rows.Count > 0 Then
'if there are rows, sort by date (most recent first)
historydataGrid.Sort(historydataGrid.Columns(0), System.ComponentModel.ListSortDirection.Descending)
End If
Where Columns(0) is the Date. However, how difficult is it for me to then sort secondarily by time. So that the grid will sort by most recent date and time.. Working down from the most recent time on the most recent date, and then moving backwards towards the oldest date with the oldest time.
I'm trying to split a date column into multiple columns by year. If I could achieve a roll-up subtotal at the end that would be awesome.
I'm thinking the best way to do it, is using a .NET datalist control, but I'm open to suggestions.
Example data:
DATE | SALES
1/1/2009 | 1234.56
2/1/2009 | 4567.89

So I have a datagridview being populated with data from a database.At this point a user may or may not selected (via mouse click / key press) one or more rows within the datagridview.I need to (upon selection) create a new dataset, datatable and add rows with the some data from the said datagridview.
For example, if a table had nothing but names, e.g.
Joe
Sean
Larry
Chris
Upon the user clicking, dragging a selection over Sean and Larry to add those names to a new dataset so I can pass it to another method for further processing.

Input array is longer than the number of columns in this table.It looks like I'm either missing a column declaration or adding the table to the set?
I am new to working with XML and have a question. I can recover any one value from an XML file but how do I recover 2 values from the same file and align them into a column format.
This is what I have been doing so far:
Dim doc As New System.Xml.XmlDocument
doc.Load("C:a_xmltestingDev_Clean.xml")
Dim list = doc.GetElementsByTagName("product") 'this returns the product ok
Dim list2 = doc.GetElementsByTagName("product_code") 'this returns the product code ok
I can pass either list into this and recover the values but not both
For Each item As System.Xml.XmlElement In list2
Debug.WriteLine(item.InnerText)
Next
Can I pass 2 GetElementsByTagName into a list?
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?
View 6 RepliesTwo quick questions about datagridviews... I have an unbound dgv and I'm trying to do some simple formatting but sadly my .net knowledge is limited at best. I'm trying to make a balance sheet and I need to do two things:
1. How can I set row(d) to sum row(a:c) for each column (for multiple years of financials)
2. Is there anyway to not only make a row readonly, but make in unselectable (to skip totaled rows)?

I am wriing a vb.net windows application to log and store information. then display it in a sortable multiple column listbox (I personally like FlexGrid by Component One). However... I am not sure how to go about storing the information. Should I go with a .sdf file database, registry, simply storing them in a file, or some other method?
What I need is to be able to:
read/write/delete from it
read possibly up to a 20mb file and sorting it without a lot of lag
be transported to multiple systems and maintain these writes (installed on many systems)
I know I could split up the reading/writing to anther thread. Even to other .DLL's and whatnot. But as for storing. Not sure what the best option is.
Here is the structure of my database: i have textbox1 and textbox2 and 8 checkboxes in my ASP.NET (VB.NET) webform.i want to retrieve the seats on the particular dates means if i enter 11/12/2010 in textbox1 then in textbox2 the output would be from seat_select column, let say (1,2,3) where date would be 11/12/2010
If i enter 13/12/2010 in textbox1 then in textbox2 the output would be 1,2
