View 5 RepliesI'm having troubles with my datagridview. Id like to use a combobox that you could type into and (as you are typing) would update the drop down list with the ability to use wildcardsThe list is populated with a table in my database. I know how to do this using just a combobox on a form, but I'm still learning everything with datagridviews.Is there a way to do this with a combobox in datagridview? If not, is there a way to do it any other way (i.e. using a textbox and having something pop up like the autocomplete windows)? I really would like to have the ability to use wildcards with this
View 7 RepliesI am using DataGirdView in my project.I have some queries listed below.
1. I want to add Rowheader' name like
Column 1||Column2
Row1
Row2
2. I want to fix the number of Row like just 2 Rows . And if I edit in datagrid or press enter after editing ,the automatic addition of the next row must be blocked.
I want all the contents both in columns and rows to auto resize its length depending on the length of text that is to appear in the cell...but it seems I cant get the idea on how to properly use the auto size method.
View 1 RepliesI would like for my datagridview to automatically fill in the column's next row with the previous entry + 1 letter. So say my datagrid is like this:
ID NextField
15-3A xxxxx
15-3B xxxxx
15-3C xxxxx
Everything is working fine if I type it in but would be nice if the user didn't have to type this each time and just have it fill in the next consecutive ID automatically when you press down to start a new row. Also i need it to work no matter what gets typed in... so if I make another ID 15-4A it will start filling in 15-4B etc. on each new row.
I have a Table with an integer ID number set to auto-increase. Does anyone know how to let SQL server fill the gap (where rows are deleted) when new rows are added? If can, how to get the scalar ID number assigned?
View 4 RepliesI saw lots of things online that look like you can't create a number that increments with every build automatically - rather you have to set it in AssemblyInfo.vb - is that really the case??
View 4 RepliesI've been using some recommended code from successfully for a couple of years now to auto-increment the build number in my project.

But I just updated my workstation from XP Pro x86 to Vista Ultimate x64 and now it isn't working any more. Everything else works, but not this. It increments the build number when I build the application, but then VS gives the following error:Error 4 Unable to apply this change while debugging. File 'D:My ProjectAssemblyInfo.vb' was reloaded. You must revert the change or stop the debugging session.So essentially I can't do anything in my application, or at least I can't run in debug mode because of the error.

View 6 RepliesI have this picture to be more clear:
My idea is when I paste (ctrl+v) for example this number : 4111111111111111
it would automatically paste them in textboxes one by one in order!
so txtBox1 will contain : 4111
txtBox2 : 1111
txtBox3 : 1111
txtBox4 : 1111
the automation of inserting credit card's number will ease so much so that user will not work so hard to cut & paste each four digits!so any suggestion of doing auto-fill inside textboxes..?
2)if I am already in txtBox4 and want to delete back with the key "BackSpace/Return" after deleting txtBox4's content and clicking one more time the "RETURN' key it would move to txtBox3 and so on until cursor gets to txtBox1...
I have a project which has a table with a list of stores. Originally the store code was a string of 3 and was padded so 1 would be 001 etc. I have had to increase this column to 8. The problem is when I read in data from a XML file the store code is padded so it looks like this '500 ' rather than '500'. This is now causing a major problem when I do a comparison.Is there a way to it does not auto pad to the full string length?
