Is it possible to take the last row added to the grid and enlarge it for viewing? Then when another row is added it enlarges and the previous goes back to normal size. When I say enlarge, almost like a magnify effect. Am I making sense?
View 1 RepliesI am trying to move from the old ADO to the new ADO .NET . However , no matter how many tutorials I read over the internet , I still can't find a way to do something which , as I believe , has to be very simple I tried to mimic the way the graphic control did but I am missing some things ... I noticed that , in the graphic way , the wizard created 4 controls :- a DataGridView control- a DataSet control- a BindingSource control- a TableAdapter controlI recreated all of them and filled their correspondent properties , but yet I can't make it work . I think what I am missing is the connection itself . I looked on the internet and I think a connection can be made and opened like this :
Dim DataBaseConnectionMY As New OleDb.OleDbConnection
DataBaseConnectionMY.ConnectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source = C:ProsoData.mdb"

And at the end of the DataGridView1 Row, I Have inserted Another Button called "Allocate" There Is also a ComboBox. that a user can select a driver and when a driver is selected. I want the user to click the Allocate Button to update the dataset/Database with the selected driver. then remove the row from the DataGridView1. the DataGridView1 should be refreshed each time a row is remove.

I have a FlexGrid control in my Windows application that contains a row of data. The data in this row is related to even more data that won't all fit on the same row. For Example:The main data row contains Username, Last Name, First Name, Middle Name, E-mail Address, Phone Number, etcA secondary row to this might contain user permissions to certain resources, such as File Server Access, FTP Access, Remote Access, etc.Now, I can use the subtotal and outline capabilities of the VSFlexGrid to make a second row, but the column widths are still bound by those set for the main data row. Additionally, I can't put real "headers" on the supplemental data. I have to fake it by creating an additional row, setting the background color of that row to gray, putting the header strings into those fields, and then adding the next row with the actual details.
What I would like to do is create separate grids for these secondary rows and "embed" them in a blank row of the existing FlexGrid control directly under the related main data row. This would give me the ability to use a different number of columns, to format these columns independently of the "parent" FlexGrid settings, as well as put a new header row for the new grid that identifies its data.In other words, I'd like to somehow make a "child" grid that's related to a particular row of the "parent" grid (not the entire grid itself). I don't know if this is possible, and if there is another way for me to accomplish this goal, I'm all ears. However, if it IS possible, I'd love some advice on how to implement it.

View 1 RepliesI want to design visual match the pairs. There will be two columns. The left column will have images and the right one will have word labels. User have to drag image over the correct label.
Since the form size is small, images will have to be smaller (thumbnails). So there should also be image enlargement when user hovers mouse over the image. The user should also still be able to do a basic drag-and-drop of the image.
My users uploads a picture and the picture get saved into my SQl Server Database.My users view the picture on the page in a normal Image WebControl with size 150px by 150px - example can be found[url]...
If the user uploads a picture of 300px by 200px the image will look funny in my static 150px by 150px Image box. Any idea how i can display the Image so it wont be fuzzy?
Also, how can a have some form of pop-up that will appear on the screen, showing the actual size of the picture from the database when the user clicks on the 150px by 150px Image.
Note: I dont want the Image static size to increase as this will totally mess up my page layout and look. It must be some form of pop-up or something. Something i have seen before i think was really cool. User clicked on the small image and then a pop-up appeared in the middle of the screen with the actual size of the picure and everything ells on the page was disabled until the user clicked on the close button.
what is the code to enlarge images as the program is running
ie double click the image and it expands

View 6 RepliesI have a databound datagridview.I have disabled automatically adding new rows to the grid. The datagridview is bound to a datatable.In it,I have also set the Protected Overloads Overrides Function ProcessCmdKeyto handle and process the 'Enter' keypress.When the user presses Enter within the Datagridview,I want the grid to add a new single row to the bottom of the grid.I have tried several methods to do so,but the grid always adds the new row to the top of the grid instead of to the bottom.I tried posting this issue in the Windows Forms Data Controls and DataBinding board, but didn't recieve any help there, that's why I'm posting this here instead.The only person to help me there said she couldn't reproduce my issue, even when I supplied her with the exact code I was using.I believe there is more than one way to implement this adding of a new row to a datagridview programatically, and browsing through the various msdn forums, I came across several and tried implementing them all, always with the same result.I don't remember all the various implementations I have tried, but here are my few most recent ones:(This is within a class I created that inherits the datagridview. This custom class was the only place I could specify the ProcessCmdKey function, it doesn't work in an instance of the datagridview instantiated directly onto a form. That is why I'm using the me keyword to refer to the datagridview)#1)

I have a form allowing user to search details of employees. the form allows users to key in 7 search criteria. the results of this search open in a new window. employee details (data) are of following 3 types: personal details contact details additional details
I want to achieve the following with the results window the new window that opens to show the search results has a tab control with 3 tabs for displaying the results for each of the above categories. hence the three tabs would be personal details contact details additional details each tab would display the required data in a datagridview control. on adding the datagridview directly to the tabpages of the tabcontrol the window does not resize to the size of the datagridview that is displayed. i understand that the property AutoResize is not applicable to a tabcontrol or a tabpage, hence 1 added a panel to each of the tabpages and then added the datagridview to it.
However, even this does not help and the results window is still does not resize to the size of the datagrdiview. i have set the AutoScroll property of all the tabpages to, AutoResize of the datagridview and results window all to True. How to do this as the results widow does not rezise even to the size of the tabcontrol that i have added and the tabcontrol ends up with scroll bttons in the window.

I have a datagridview control that where I need to color the rows based on a value in one of the cells in each row. I'm using the CellFormatting event like so: [code]This works fine when the grid loads and when I scroll it, etc. But when I click on the column headers to sort the grid, e.Row Index is always zero and all of the rows get the formatting of the first row..[code]For some reason, e.RowIndex is set correctly here but not on the other methods. The only thing you have to worry about here is it can be -1. But when I tried to use other methods, including PrePaint, I had to deal with it always coming up zero on a sort. If I exclude the zero case, like I excluded the negative one case about, then the first row is always white!!! I'm not sure why this works, but it does. It also produces no flicker beyond what I got using the CellFormatting event.

How do I add the button that scrolls down / up as I add or delete rows on the grid?
I have a DataGridView that I am adding rows to programmatically.Normally, when I add the first row of data the SelectionChanged event firesBut my Grid is anchored to the top and bottom of the form and when I make the form smaller such that the height of the Grid is zero, the SelectionChanged event does not fire when adding the first rowIs this by design? It doesn't seem logical to me.
