View 8 RepliesI have a datagridview and a bindingsource. The first column is a comboboxcolumn which is bound to a table field and then the rest of the items are populated from another datatable. What I have on my other forms is a textbox called txtfilter and on the textchanged event I have this
Me.ProductBindingSource.Filter = "BatchNo LIKE '" & txtFilter.Text & "*'" that works great. Now I want to filter the combobox columns just like this.
In my datagridview there are two dependent columns, one is category and the other is items. So I want to filter my item column list as per selected category. But the problem is that when I change the category wise data to datasource of items combobox, previous selected items names disappear because previous items is not in current datasource.

View 27 RepliesHow 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'm writing an app for someone where I am pulling in work orders table information. The information includes: worknum, fname, lname, customername, description, etc. I do not plan to update the data in this table, only to read from it.I'd like to display a combo box for the work order numbers. The user would start typing the information for the work order in and it would autocomplete based on what's in the list. As work orders are displayed in the combo box, I want to update the data in text boxes representing the various fields.
I'm thinking rather than query the database several times, it would be a good idea to create a DataSet with information for the work orders table within the last x months then query the data from that dataset. I know there is a DataSet.Select method, but it looks like it returns the entire row. Is it possible to retrieve just a column of distinct values? For example, I'd like to do a select statement similar to this:
SELECT worknum FROM {WorkOrderDataSet} WHERE date >'{today-x}
The first part in curly brackets is meant to represent the work order dataset I create when first importing the data from Access. The second part in curly brackets will be replaced with variable data to represent a date to reference. I also don't think I'll need distinct because the workorder is unique (edit: is a primary key)Is it possible to retrieve just a column of distinct values from a DataSet with multiple columns? How do I do this?

I'm develloping a small application over na Access 2007 database. how can i pass the value of a combobox to a query being built with the query builder tool?If I use ? in the Filter column I�m prompted to enter the value but what I need is to pass the value of a combobox in a form. I tried to use:
HTML
=MyForm.MycomboBox.Value
but it is ignored, interpreted as the value to be filtered.
In Excel 2010 (but also in older versions you can find a nice functionality - auto filter. When you just put some data in a row and press CTRL+SHIFT+L you activate Auto Filter. Now you press the down arrow and you get what I need... A new window appears. This window include buttons ordered in something like a context menu a textbox and a checkedlistbox. The windows definitely is not a classic form, because when you operate with the controls on it, the original excel windows is still the active window. The window can also be drawn outside of the main excel windows.
View 5 RepliesI have AutoFilter in place in my sheet. I want to sort data using the AutoFilter itself and not by normal sort. I want the client to see the down arrow on the autofilter button, which tells that rows are sorted on this key.
I have 'sheet' as an object :
sheet.Range("A2").AutoFilter then Or something else ??(Ensure the syntax for VB.Net and not VB Script)
Add persistence to multible DataGridView in terms of Hide/Show column and column width
View 1 RepliesIt seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?
