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?

I'm trying to write a very basic program in VS 2008 (VB.NET 2.0) that will help me to quickly set up new servers. One of the things I want the program to do is hide the "Volume" and "Network" system icons. I cannot find where that setting is or a way to programmically change it.

I am working on Treeview control and Gridview Control VB.NET08. In the Treeview i have Parent and Child Nodes. Like: [Code] Comparing the Parent Node text and first two digits in the Column values. I want to add rows inbetween the gridview rows based on the parent and Child Nodes. If i expand the First Parent Node Called "31" then according to the Number of Child Nodes (for first parent node(31) there are 5 child nodes.) add rows in the gridview.
These New rows should be add under the 31-xxxx. If i expand the 32 Parent Node based on number of Child Nodes, add rows under the 32-xxxx. [Code] I am getting the rows in the end of the Gridrow not in the Specific row.

Our site is developing against a 3rd party API (Wonderware) that returns datasets and datatables from certain calls. The issue we are having with some of the calls is the data returned is more than we want to show to the end users. We are binding the data to a datagrid, and will sometimes get back 20+ columns of data we don't need to show. Is there a way to filter the datatable of columns before binding it to the datagrid? Right now we are using the datagrid to hide the columns, but I think it would be better to strip out the columns of data we don't need before binding to the grid.

Is it possible to add a button column to a datagridview and then remove a select group of these from rows without removing the rows themselves? That is, I want the ability to hide or remove these buttons in certain rows after certain actions have occured. I realized that I could simply delete the rows with these buttons, but I want to keep the data in these rows visible without the user thinking they have to use the buttons. I am assuming that I can also disable the buton in the desired rows as well.

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 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.

I want to make a gridview with 4 columns. (Checkbox, Hyperlink name Title, Dynamic name Price, Dynamic named ASIN#)I want to be able to add new rows to the gridview from three different strings. I have a function that looks like this:Private Sub displayData(title As String, cost As String, asin As String)Is it possible to even add new data to the gridview with these strings.I've looked all around online and most things deal with databases. I'm also not 100% sure how to initialize at gridview.

I have a gridview that contains user info and one of the columns is a date when the user was added to the system. Is it possible to use the GridView.onRowCreated method to check if the user was added within a given time frame? If the user was added within that timeframe, then the row is added, if not, then that row is not added.
Note that I can't modify the datasource of the gridview, so I need to do this somehow as the gridview is being created.

Is it possible to loop through a gridview with more than one page, the gridview I'm looking at has a pageSize of 20, there are say 26 records (over two pages) and I want to be able to loop though all the records.
For Each row As GridViewRow In GridView.Rows The count of the above is only 20 as the pageSize is set to 20, I can see that the pagecount is 2 but how do you loop through the next page in a gridview? Or would I have to just iterate through the orginal datasource?

I have a dynamically-created GridView which to which I'm attaching a handler using the AddHandler command. The problem is that when I try to refer to sender.rows within that function, it won't do anything because it says that sender.rows.count = 0. I've done enough dynamic form creation that I'm pretty sure that I'm creating the controls, binding them, and adding the handler at the proper points during the page init/load load_complete. Also, I have nearly the exact same code-behind on another form that is not dynamic, and it is able to access the values in the rows.
Considering that the RowCommand event is firing, it's clear that I'm clicking on a row. For some reason it's just not in scope for the handler event. Background: What I really want to do is access the values that are databound to the row. I'm creating a SQLCommand and binding that to the dynamic grid, and I would prefer to talk to the grid's datasource, but that doesn't seem to be possible. Perhaps I'm missing something, but for now it seems that reading the values from the GridView (which I hate doing) is the only thing that works.

I have asked a question similar to this in the past. I was able to resolve it by removing gvRowDataBound completely from the code. This is similar code except I can't remove gvRowDataBound sub.
The issue is that when you click the Edit button of the first row, it allows you to successfully update that row.After the first row, if you click on thr edit button of any other row, enter the value to update, it doesn't update that row.
Instead, the cursor moves down to the next row. I didn't design this and having difficulty figuring out what needs to change.

So I've created a gridview with checkboxes so the user can check as many fields as they want and delete them with the click of a button. It works except that it deletes all selected rows except one, the row with the lowest number. I can't firgure out what logic error is causing this.
Here's the code for the delete button procedure:
Protected
Sub btnDelete_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnDelete.Click
Dim count As Integer = 0

I have a gridview which gets its input from a database with sql. There is a column with checkboxes in the gridview, so you can select which row you want to export. There is also a column that's called "Project Number". When you push the button "Export" the program should figure out which row is selected, get the project number from this row and connect to the database to get the data from the selected projectnumber. I already got the part where it gets the selected checkboxes. But I'm stuck at the part where it gets the projectnumber from the selected row. Must be something with Datakeys I think.
