View 1 RepliesDatagridview - Sort Datagrid View Column With Numbers And Texts On Column Header Click?
Feb 13, 2012It 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?

ListView BackColor Fill Entire Column?
Dec 21, 2009In the screenshot, you can see where the BackColor is set for each item added to the ListView on the right. How can I fill the white space between the columns as well? I'm assuming the column width is the highlighted portion plus the white space. I thought setting the BackColor would fill this whole portion so that there essentially would be no white space at all showing anywhere in the listview (except maybe at the bottom). Is there a Property I need to set to do this? the listview has 1 column and it's autoresize property is set to CellContent.

Extract Specific Texts From Parse Given Header Names
Feb 6, 2010I have a parse from Wikipedia saved in a text file in the following form: The town itself is situated to the south-east of the rock, and overlooks the Palaia Monemvasia bay. A small hamlet with about 10 houses lies to the northwest.The founding of the town and fortress of Monemvassia most probably occurred in the 6th century AD. The town was founded in 583 by people seeking refuge from the [[Slavic peoples|Slavic]] and the [[Eurasian Avars|Avaric]] invasion of Greece. From the 10th century AD, the town developed into an important trade and maritime centre. The fortress withstood the [[Arab]] and [[Normans|Norman]] invasions and conquests in 1147. Cornfields that fed up to 30 men were grown inside the fortress.What I need to do is to extract specific texts from the parse given the header names. For example, if I type in a textbot Geography I need ONLY the geography text returned.

Any Way To Paint Background Of Column Header
May 7, 2009I am currently working on my own listview control, and I was wondering if it was possible to get it to not draw the text for the listviewitem when the listview is in report mode? What I have been doing is putting all of my information in the tag and leaving the text property blank so it doesn't paint. Andis there a way to paint the background of the column headers? Because It only allows me to paint the actual column header? Here is what im talking about for the background of the column headers.

View 3 RepliesDataGridView Column Header Text
Sep 15, 2011I have a windows application with many forms. We use the DataGridView control on most of the forms, but on a new form that I designed I have four DataGridViews. All of the DataGridViews on this form do not dipaly the Column Header Text when the form is displayed when running in the IDE. I do not receive any errors or messages. The other DataGridVeiws on other forms display their column header text just fine. I am at a loss as to why this is happining on this form.
UPDATE: If I add the desired text to the column.HeaderText property at the end of the form load event it displays the column header text. For example AssignedAmountColumn.HeaderText = "Amount" it displays Amount in the column when run from the IDE.... However it dosn't display when the property is set though the Columns property at design time.
Delete On Column Header In Excel?
Apr 26, 2012Looking at deleting columns in excel and have found several threads that show how to delete an entire column which I have tested and done successfully. These columns were all identified by "A", "B", "C" and so on...
I was wondering if it was possible to do the same thing using the column headers. When deleting the columns in excel, one has to keep in mind that columns deleted from the left will shift the entire sheet to the left and if one is not careful, the next column[code]...
Let's say a user wants to delete the 'Middle' column (assume as column B in excel) and then delete the 'Suffix' column (assums as column D in excel). If they don't know to work from right to left when deleting columns, they would write code that would delete Column B and then repeat that code for Column D. However, once column B is deleted, all columns will shift left, which will result in the 'Phone' column (formerly column E now column D) being deleted instead of the 'Suffix' column (formerly column D now column C).
If there was a way to delete the columns by their headers (i.e. Middle, Suffix...) this would eliminate the problem; to me it seems a bit more intuitive as well.
Disable DGV Column Header Click?
