I am attemting to read a .txt file database into an xml file and then read the xml file into a DataSet and then bind the dataset to bindingSources and then subsequently bind comboboxes and text boxes to the binding source. I am struggling with how to create bindingsources with different filters. I am not sure if I am even going about this the right way. Perhaps there is a better way. I already have the program working using traditional OLEDB and creating different datatables but I wanted to be able to add and edit my datafile so I decided to convert it to a xml file.

I'm designing a form wherein a datagrid is being filtered from numerous controls.
The issue im having is each filter overrides the previous one. Just wondering the best way to approach this problem.
Heres a snippet of my
Private Sub MakeIDComboBox_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MakeIDComboBox.SelectedIndexChanged
Sheet1BindingSource.Filter = "Make like '" & MakeIDComboBox.SelectedItem & "'"
End Sub

What is the difference, and why don't any of these methods work?

I have the code below and would like to sharpen the image in the increments of 10% starting at 0% to 100%. How do i apply separate filters so that when i move the track bar, i am able to see the effects take place step by step?

Dim sharpness As Single = CSng(TrackBar1.Value / 100) ' no change in brightness

I would like to sharpen an image using pure vb with no filters or unsharp method.Then use a track bar to slide through so that the image in the second picture box shows the effects of sharpening, up and down. I have the code below but it gives me errors:

Scenario: FormA has a DataGridView with a DataTable as it's DataSource. The DefaultView of the DataTable is set to a particular filter, say "UnitFreight < 2.00". The user selects multiple rows then selects a context menu item to open up form2. Form2 does a bunch of stuff and in this example it will change the UnitFreight value in the selected rows on form1 to say 2.27. It also raises an event in form1 to adjust attribute cells such as UnitPrice.
The issue is that doing the above example puts the selected rows out of the range of the applied filter and I believe this is the issue because I end up getting a "Column named UnitPrice cannot be found" error. This is happening during the update of those attribute columns. I'm guessing the row has been filtered out so there's no column to be found. If I do the update without the filter applied it works fine. So my question is, what's the best approach to updating the data in this situation. I've started converting the updates to work against the DataTable directly instead of the DataGridView.
Has anyone tried merging multiple HTML Files to single HTML File ? am in confusion whether we need to treat HTML files as an ordinary text and and to append text or is there anyother way..

I'm trying to develop a Mail Merge using Bookmarks in a word template (1 page doc). It works ok for the 1st record from a datatable (source of data for bookmarks), and then just piles the other records into the same bookmarks. After the 1st insertion I need the code to goto the end of the doc, insert a page break and append a fresh copy of the template for the next insertion. The mail merge could have many 1 page letters in it.
strTemplateDir = Trim(txtDocument.Text)
wrdApp = CreateObject("Word.Application")
wrdApp.documents.add(strTemplateDir) 'open new word doc based on template
'make it the active doc

View 2 RepliesI have two RichTextBoxes, each of which can have any sort of formatting. I need to be able to take the rich text from box 2, complete with formatting, and add it to the end of box 1, preserving the formatting of both box 1 and the appended rich text.
I've not managed to find anything usefull on this anywhere apart from hints pointing to manually re-building the RTF codes for the result (but no actual VB / C# / C code to perform this or similar).
I'm having problems with bindingsource. I have a proc used to update a datagridview from a bindingsource. When I run the debugger, the datatable appears to be populated rowcount is 2206 and 7 columns. When the bindingsource.datasource is set, everything looks good. The filter appears to be ok, however, when the datagridview is set to the bindingsource, it's not working. I have it in a try/catch block and an error isn't being raised. When I reference the columns to size them, an error is raised. Below is the snippet of

All fields from my class objects are added to the columns collection of DataGridViews, when the forms or custom controls that contain them are viewed within the VS 2005 designer. I haven't been able to figure out how to stop the designer from auto-adding all of the fields found within the bindingsource object.
View 6 RepliesIf you have a form with two datagridviews that were dragged on to the form from a datasource that have a parent/child relationship with foreign key constraints. Is there any difference between using the binding navigator Delete button or adding a button to the form and in the Click event put "somebindingsource. RemoveCurrent". Basically what I'm trying to find out is if clicking the navigator Delete button causes "Removecurrent" or does it do something else or something additional.

When I drag an item from my data sources area onto my form, VS automatically creates a tableadpater, bindingsource, and bindingnavigator for me. This is great. The name it picks "xxxxxtableadapter", "xxxxxbindingsource", and "xxxxxbindingnavigator", where "xxxxx" is the tablename, is in my opinion a bit wordy.
View 3 RepliesI have a dgv and in it the user can move around column's or resize columns or filter columns. Now there's an issue when the user try's to move the column's around because you have to click on the column and drag it over. But once you click on it, it sorts that column in ascending (or descending) order.
View 5 RepliesI have a DataGridView to display the content of my database. I Queried the required fields to a Dataset and Used this as DataSource for the Datagridview. Now i want to add dropdown filters to each column as we see in Excel Sheets. Is it possible and how.
Any how i require dropdown for the columns i also tried from below link to set the BindingSource.Filter = value but i did not find this property for Datagridview[URL]..
is there any possiblities like this select two conditions in one dataview like
Childds.Tables("ColumnList").DefaultView.RowFilter = customername='hello'
dv = Childds.Tables("ColumnList").DefaultView()
it has given correct answer but
Childds.Tables("ColumnList").DefaultView.RowFilter = customername='hello' or customername='hai'
dv = Childds.Tables("ColumnList").DefaultView()
In this case it takes only first one and ignore the second or condition

I have a windows applicatin built using vb.net 2005 - backend webservice that uses a sql db. I'm working on a form that contains a datagridview that I bound. My pic below to displays the outcome. I have a combination of dropdowns, textboxes, checkboxes, etc in the grid. I now need to add several filters and would like to know, what is the best approach:
1) adding the filters to the header row in the grid.
2) adding the filters outside of the grid as you can see i've started to do from looking at the pic?
I've been reading how it's possible to add them to the grid; but not sure if this is possible to do this when there are controls other than text boxes inside the grid.
I'm currently searching a database using filters. The user can use any or all of them, and to achieve this, I have the following
Private Sub GetData()
Dim QueryString As String = "SELECT * FROM Inventory WHERE"
Dim FiltersExist As Boolean = False
'Set Up Connection to Database
[Code] ....
I would like to create this using the query builder instead, but I don't know how to tell it to ignore a parameter if its value is null or an empty string. Another problem with the way I'm doing it now is that if the user has filtered the results, then adds a record, I cannot use the Update method of my TableAdapter, because the datasource of my DGV has changed. Even if I can't achieve what I want with the Query Builder.
Is there a way to use the DataTable.Compute Method with 2 or more filters, i have googled a bit and cant seem to come up with answer?

I am looking to find the best way to do the following: Filter data based on the drop down filters, as long as I am within the same product category (e.g. toys, puzzles, etc...), but in different web forms (product grid and product detail).So if I select toys under $25, I need the filter to the toys in a grid format, but if I click to view the detail I need the filter information so I can filter the related items display.Display certain filters depending on the product category.Right now I believe that if I build a user control and session variables that I should be able to accomplish this.
EDIT: Right now I am using the page_load event to update the data and would like to avoid AJAX for right now.
