.net - DataGridView Resizeable Columns But Last Column Can't Be Resized Bigger?
May 10, 2011
For c = 0 To grd.Columns.Count - 1
grd.Columns(c).Resizable = DataGridViewTriState.True
Next c
That allows all the columns in my DataGridView to be resizable EXCEPT the last column. Why?I DO get the little resizable-mouse-pointer... but you can only make the column SMALLER, never WIDER.(Same problem if I try to set all the columns to Resizable, using the VB.net IDE)Shouldn't I be able to resize ANY column I want, bigger or smaller?
For this application, I need a resizeable window that contains 2 (two) lines (In a cross hairs design) that are both resizeable and rotateable. I need them both to rotate at the click of a button (The button is on a BubbleBar, but the code is the same for a normal button control). I also need them to resize with the window (It has to be accurate). I have tried using LineShapes from the Visual Basic PowerPack, however the amount of trigonometry involved with this solution was too much for me to implement and understand.I also tried using a WPF ElementHost to accomplish the same thing, without luck. I tried using the RenderTransform property of the WPF Lines to rotate them, but I could not apply both that and resizing to these lines.
I need to display a column called Full Name in the my datagridview, but the datasource (datatable) does not have a FullName column. It only has FirstName and LastName columns. I'm setting up my DataGridView like this:
I have a user control with an embeded DataGridView. I exposed the Columns property so that the columns collection could be edited in the visual designer:
I am using VS2008. I have a table in which the jpg images are stored. I can retrieve the images from the table and display it in datagridview. But many images are of different sizes. So the cell height of the datagridview changes according to the image size. Is it possible to give a fixed cell size for the image column and also shrink the image to that cell height.

I am trying to implement a DataViewGrid in VB.NET that will be simply for identifying and selecting GIS features that are already within a database. Simple enough with DataGrids and DataSets, although there is one slight twist.First, I need to be able to populate the grid based on one record of the column [Name] that is chosen from a ComboBox(I have been able to populate the ComboBox, but not the grid).Second, I need to restructure the DataGridView so that each current column name is in a column called "Field" and the row for that one record chosen is in another column called "Value".As you can see here, each "Field" is a column name and each "Value" is one record for each of those columns. So, if I could somehow parse through all of the column names into a "Field" column, and also populate a "Value" column with one record for each [Name], I would be on the road to happiness.
I am currently building a web browser in which i want to have 4 browser in it running at once.The main idea is there are 4 browsers in a formation where you can adjust each one to the correct size a bit like in this image (i hope its a permanent link)[URL]..if this would be thery hard to do then i would have to do somthing like in fig 3 if its simpler.
I am running a program that needs to allow the user to be able to change the size of a text box at run time. I know I need to use the MouseDown, mouseMove, and mouseUp events. I just need some help with the coding to send the information.
I have a Dataset with a Bunch of Columns used in a Report (DevExpress XtraReports) (DataSet being the DataSource). The Dataset has many columns, and i need to read a column (based on the row type), and decide which column value to read for the row, and apply formatting based on the row type.
[Code]...
Is there a suggested way to handle this in the Report or at DataSet Level (excepting the formatting part)?
It 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?

I 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.

I'm trying to create a message box that shows a column for Years, represented by 0-10, and an amount, as a $ wise decimal in another column.I was wondering how to create a multi column message box with column headings o.o.
I used sqlbulkcopy to upload huge data from local to remote. It works great.The only problem is that there is a table tClaim in which there are 50 columns. One clumn "IsUpload" do not need to upload. How to upload all columns except for this column? If I use columnmappings, do I have to code add column one by one?
I am working with two different connections because the information I need is stored in two different locations. One being Oracle, the other being Access. I pull all the information I need from Access with the exception of one field which I pull from Oracle. When I add this field to my datatable, it adds it to the end. I am wanting the column that I add to be between column 1 and 2 of my current datatable. Anyone know the best way to do this? From what I could find, there wasn't a way to re-arrange columns. Here is my code.
Dim da As New OleDbDataAdapter(" SELECT tblSummary.WorkOrderNumber, tblLabor.Crew, tblLabor.NumberOfMechanics, tblLabor.NumberOfHoursPerMechanic, tblTasks.TaskNumber, tblTasks.TaskDescription FROM (tblLabor tblLabor INNER JOIN tblTasks tblTasks ON
i have a datagridview with three columns. i set the first column to visible=false, so the user can only see two columns.when the user presses the tab key in the first visible column -- column(1), i want to ignore column(2) so that the user only tabs through the rows in column(1)i can't get it to work. it will always tabs through the rows in column(2) even if i use the column name.
I'd like to autosize listview columns to fit the column names. From what I saw this should do it but it doesn't work for me. Can someone see what I'm doing wrong or know of a way to do it? The listview is designed to dynamically build the coulmns based on the number of coumns in a recordset.
I have been trying to pull rows from my access database into a list box, so the rows do appear on the list box, however the columns are not spaced out, and when I put & Space(10) & inside the ListBox1.Items.Add() the values are all scattered around. How do I fix this?
Below code is supposed to update a table in oracle with rows imported. But it seems to update all columns in the table with only the first column which is imported from the CSV file. I figure its the "ReadFields" property which needs to manipulated/changed.
