How to hide or show rows in a table layout panel.
As I used rowstyle property and it works
But the issues are
1) It works very slow
2) It seems as form is vibrating and lightning behind the panel when rows are hiding or showing(jerky motion of hiding or showing)
I also used the control .visible property for each control of the row but it also make same problem of being slow
I am creating a TableLayout in which the rows and columns are set by the user at runtime.There initial controls on the form are rowsTextBox, columnsTextBox, button1 and tableLayoutPanel1.I modified some of the code from my initial program. Here's the old code.
Private Sub button1_Click(sender As Object, e As EventArgs)
tableLayoutPanel1.RowCount = Integer.Parse(rowsTextBox.Text)
tableLayoutPanel1.ColumnCount = Integer.Parse(columnsTextBox.Text)
[code]...

View 1 RepliesI'm using a TLP and it contains controls that exceeds it's height, so it's normal for a vertical scrollbar to be displayed. So far so good, but i can't figure out why a horizontal scrollbar is also being displayed when my controls width do not exceed that of the TLP. Is there some way to remove this horizontal scrollbar?

View 4 RepliesI have a listbox populated with peoples names. When I click on a persons name in the listbox, a datagrid will unhide itslef, connect to a DB, and list all of the pictures that person has. All the pictures are stored on a drive in a folder named after the person. i.e.
Greg Palinkas has 52 images stored in F:PicturesGregPalinkasImages.
I would like to display all of those pictures in a Table Layout Panel populated by the choice I made in the listbox, so if I select Greg Palinkas, the Data Grid is pupulated with the names of all the images i have, and the Table Layout Panel is populated with all the pictures I have in my GregPalinkasImages folder. I have got the Data Grid updating and running smoothly, but am lost as to how to get the images to come up.

View 6 RepliesI need a help with showing/hiding rows in datagridview by setting the trackbar value. The below example works if there are not too much rows. If there are greater number of rows then after you change a value of trackbar you must wait for a few seconds for the datagridview to redraw and only then you can use trackbar again.Apparently I must use multithreading to achieve what I want: when I use trackbar, datagridview starts to redraw, but if I use trackbar again before datagridview finishes redrawing, it immediately stops redrawing according to previous trackbar value and starts to redraw from the beginning according to current trackbar value. That way trackbar will never be frozzen (stuck, unusable...).I tried with backgroundworker but got error "Cross-thread operation not valid: Control '' accessed from a thread other than the thread it was created on." I have old and slow computer. If you have new and fast computer maybe you wont experience what I'm describing here so try to increase number of added rows in line 'For i As Integer = 1 To 5000' (I added 5000 rows here) - and if you have even older and slower computer than you will have to decrease this value or you will have to wait to long after you drag the thumb in trackbar.
View 5 RepliesI use a Repeater that's databound to a DataRowCollection and programatically build a table through that. I have something similar to:
Private Sub SubAcctGrid_OnItemDataBound(ByVal sender As Object, ByVal e As RepeaterItemEventArgs)
If e.Item.ItemType = ListItemType.AlternatingItem Or e.Item.ItemType = ListItemType.Item Then
Dim currentrow = TryCast(e.Item.DataItem, DataRow)
Dim acctSummaryTable = New Table With {.ID = "acctSummary" & e.Item.ItemIndex, .CssClass = "minisub_acct_table"}
[Code] .....
I can't pass in the correct element ID, though. From what I understand, ASP.NET transforms the ID I assign into some huge long ID for the sake of uniqueness. For example, I assign a table with the ID 'drillDownTable0' and it spits out 'ctl00_drillDownTable0' in the HTML markup. It worked the first time around, but then the Repeater gets binded to a new row and then I get 'ctl01_drillDownTable0' so on and so forth. I've tried the ClientID, ID, and UniqueID where I add the attributes to the Cells in the code above and they don't do what I need to. Is there any way I can get that ID and pass it to the Javascript function? Or I guess a better question is: When are the IDs generated and can I get to them before the page is rendered in HTML?
My problem with AddNew. It really is somewhat simple, but I can't figure out the solution. I have a form where I show a list of my rows with a given a table. The user can then select a row and press clone, which then will try to make a copy of that row.
Here is a snippet:
Dim rowToCopy As cmaDBDataSet.cmaPropertyRecRow
Dim originalID, newID As Integer
rowToCopy = CType(CType(Me.CmaPropertyRecBindingSource.Current, DataRowView).Row, cmaDBDataSet.cmaPropertyRecRow)
originalID = rowToCopy.id ' id of row to be copied
[CODE]...
.... and continue to copy the rest of the data to the newrow...One of the items in the row is obviously a primary key called id. I can not copy this data since I am creating a new row. My problem is, how do I set that value!? or atleast retrieve the value for the newly added table. I need that value so that I can call another form to actually allow the user to modify this newly cloned data. I tried using EndEdit, UpdateAll, no worky. THen I thought I could assume that the newly added row would go at the end of the table so I used MovedLast then got the currentRow id from there... That worked well until we did some deletes within the table.

I have a program with three tabs. On tab one I use a folder browser dialogue and load file names into a listbox. These are usually ".tif" image files but could be other image formats. I save the folder location in a variable. On tab 2 I have a Flow Layout Panel. I need to 1) use that folder location on tab 1 as the source of files to be loaded into the flow layout panel and have it do so when I use the Folder Browser Dialogue; 2) I need to click on these tab2 images (in the Flow Layout Panel) to select them, and to trigger events. Mainly create a list of selected image thumbnails.
View 3 RepliesI have been trying to understand how to make thumbnails that I create from a directory, and place in a flow layout panel, selectable. That is, when someone klicks one of the thumbnails that thumbnail should be selected and, either automatically or by the click of a button, a new window (picture viewer) opens and shows the original picture. This is probably very easy to implement, but I am at a loss for the moment.I've tried to find an answer to this by searching the forums, but nothing good has been found so far.
[Code]...
The above code works perfectly and creates thumbnails from the directory c: emp and whatever subdirectory the user writes in the textbox (textbox2). No problem here, it is how to proceed to the next level that has got me stumped. As stated I want the user to be able to select one of the thumnails to get a better look at it in another window. So in selecting it, the procedure should get the path to the original image, and the rest is magic.
during the development of my project, i'm incurred in the need to use the flow layout panel, but the real need is to show these panels with a defined size without using scrollbars.
I think a kind of dynamic clip of these panels.
For example.
I've a flowlayoutpanel of this visible size (100,200) but its real height is 500, now i've to show to the users the other content of the panel, without using scrollbars.
I am looking for the windows mobile equivelent of a flow layout panel (or any other control that I can use to hold custom controls)
View 2 RepliesI'm curious if it is possible to hide a group of text boxes from view in a form until a particular condition is met, and to have a custom set of text boxes for that condition. To give an example; I want radio buttons offering choices for a manner of searching records, the user selects one and then a specific set of text boxes are displayed for the user to utilize, if a different option is chosen a different set of text boxes will be shown. Is this something that can be done?
View 7 RepliesI'm working on a visual studio 2008 VB.Net project (.net framework 2.0), and am having some trouble with the Panel control using a fixedsingle border. As a small example of the problem, suppose I have one Panel2 contained inside of Panel1. If the Left position of panel2 is set to 0 (meaning it's border is up against the left edge of Panel1), the left border will show as bold, and slightly indented.

I have a panel that Iv added some groups to dynamically. Inside this same panel I have another panel that is NOT visible. I also added some groups to this panel. I placed a button "btnMoreLess" that sets the nested/hidden panel .visible = true however I never see it appear. If I unnest the panels it seems to work, but does not have the effect I am looking for. I want all these groups to be inside the main panel, and have scrolling enabled. The hidden panel is set to autosize so it wont scroll. My thought is that when the click "btnMoreLess" the additional groups will become unhidden and cause the scrollbar on the main panel to appear with all the additional groups. Perhaps there is another method to do this?
