I am trying to fix a vb.net program that works with windows xp but not windows 7. The following steps will recreate the basis of the problem I am having. 1. Run MS Visual Basic 2010 on Windows 7.
View 7 RepliesWhen a user is editing a given piece of data, they're allowed to add messages/comments. These are stored as child records in a SQL database. Clicking on the Add Message button brings up a panel (pnlMessage) courtesy of the AJAX ModalPopup Extender. This takes some input and, when the "Send Message" button in the panel is clicked (I learned the hard way to NOT make that the 'OkButton' property), the message is stored in the database and an email is sent to the intended recipients. No problem there.
However, I need to be able to allow the user to add new email addresses (so long as they are registered in our database). I have another ModalPopup / panel combo (pnlSearch) that's tied to a button on the previous panel (pnlMessage).
The user is supposed to be able to add an email or click on a search button to populate a list to choose from.
The pop-up panel (pnlSearch) comes up just fine, but clicking the "Lookup" button (which instigates the search and returns a collection of records that the user is supposed to pick from) closes the panel.
Previously, I ran into the problem of having the Button.Click event never firing when I put the Button into the "OkControlID" property (the CancelControlID works fine since I don't want to do anything). Removing the "OkControlID=Button" line allowed it to work perfectly with the Button.Click event firing as expected.
So now I have the Search panel with a button for "OK" and a button for "Search" - but the panel should stay up and visible after the Search.Click does it's thing. Am I missing some property that basically says "don't close the panel when this button is clicked"? Of course, if I bring up the panel again in the same session, the results from the previous effort are there (the search results).
In VB6 I could embed a panel or picturebox containing controls or images within an outer panel or picturebox. If I moved the outer control then the embedded panel would move with the outer panel and stay in the same relative position, which is what I require. This doesn't seem to happen in VB.NET, the internal panel stays fixed in its location, even if I have pasted this panel within the outer container. Is there are trick to this or do I have to code to get the internal panel to move with the outer one? How does an internal container remain embedded within an outer one?
View 4 RepliesI have a number of textboxes and labels in a panel which has to scroll in order to view them all. The user is then able to scroll down and click on one of the labels which has a textbox that appears so the user can change the corresponding value in the label. For some reason, if the user has to scroll down at all to any of the labels that are initially out of view, when they click on the label the textbox appears far below as if it was at its initial position and not directly where the label currently is.

I use panel.controls.add to add controls to the panel. But... they insert at the very top of it.
I tried the BringToFront and SendToBack methods, but does'nt seem to be working.
what i want, is that they dock at the top of the container, but if there is another docked control there, the new one is displayed below that one...
Yesterday I installed vs2008, installed SP1 all seems well.I have converted a project (from VS2005), it works fine but....When I try and modify any of the forms none of the controls aer displayed on the form.Additionally I have noticed that each form has a formname.designer.vb file, the top few lines of the code in the designer.vb files are;
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
Partial Class frmFullMarketView
Inherits System.Windows.Forms.Form
[Code]....
Then my controls are listed. Do I have to copy the code held in the seperate designer.vb file back to the 'formname.vb' file for all my forms?If so, why does VS2008 create all this extra work when converting forms from vs2005?
I need transparent panels. I simply set that background color of controls to Transparent - this does not solve the problem, as the transparency simply shows the background color of the form, but does NOT show any controls placed on the form, which is the crux of my problem.Why? Because I'm trying to use this skinning example, which does the skin by creating a user control, and make the panels show the skin's background:[URL] It seems I'm going to have to override the panel and paint it's background manually, but I don't understand how it all works; I've created a new class and overridden the panel, but the painting stuff is way above my head.
In the form's class:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'Panel1.BackColor = Color.FromArgb(0, 0, 0, 0)

I have a form that searches a db. Some searches will always result in one row of data, others might return multiple rows. I want to have the data from a single row shown in text boxes and the multiple rows show in a datagridview is it possible to hide/show those depending on the amount of rows.
View 6 RepliesI am trying to add controls to a Panel in a loop, but for some reason they are being added from the bottom up instead of top down.In a little test program I am running this

And this is the result I get ... the controls are added starting at the bottom. I need them to start at the top of the panel, with each new control being added under the previous one. If I remove the Dock statement, then the controls just get added on top of each other.
I've successfully been able to add controls (labels, images, buttons, etc) to a panel control (using VB/ASP). This panel control, I refer to it as "insertpanel". Then I add this panel to the main panel on my webpage which I made during design time. The problem I run into is that when I add multiple controls of any type to the panel, they are all added in line with each other. I tried giving my image some css-styling of[code]....
View 1 RepliesWant to use several panels on a single form and have them turned on based on what button you click. Think I can figure out how to turn panels on and off but I find it difficult to manage multible panels within a single form in Visual Studio.When I create multible panels they end of connect to eachother instead of connecting back to the main form and when you add child controls it is difficult to know what pannel they got connected to.

View 6 RepliesSo I have 2 picture boxes, a textbox, and a button. One of the picture boxes adds another row with the same controls but moved down when clicked and the other picture box (should) remove the same row that it was clicked on. I have PictureBoxAdd1, PictureBoxRemove1, TextBox1, and Button1 set up by default and when PictureBoxAdd1 is clicked, it adds 1 at the end of the name properties. Now, how do I remove the appropriate row when PictureBoxRemove is clicked? Say I have 5 rows (but the amount of rows available will depend on how many PictureBoxAdd was clicked), if I click on PictureBoxRemove4, then PictureBoxAdd4, PictureBoxRemove4, TextBox4, and Button4 should be removed all together.

View 9 RepliesI have a solution with about 5 projects, the main (startup) project is a windows forms project while the others are control libraries that contain some custom controls. The main winforms project however also contains some custom controls.
Recently, the controls in the main winforms project have stopped appearing in my toolbox. The controls from the other control library projects appear just fine, but none of the controls in my main project will show...
Some of the projects are VB, some are C#.
I have tried everything I know to fix it:Delete bin/debug folders and restart
Build, build, build, build, and build Target the same .NET Framework version and CPU platform in all projects Build again Nothing works...
All projects target .NET Framework 4.0 and compile for the x86 platform (since I am using Access db). All projects build successfully, no errors. I can run the solution just fine. I can even declare and add the controls in code and they work just fine. They just don't show up in the toolbox so I can't drag them to my form and I have to dig into the designer code everytime, which is really annoying!
how to add controls in panel control runtime. I mean, I want to add group box at runtime. When I click on my button, it should add a group box in my panel and when I click again, it should move the first group box down and add the second. Every group box should have a label control in it.

I am working on a project for a handheld in Visual Studio 2008 where I need to add a group of labels to a panel that correspond to a record on the database. The record is a "Pass/Fail" Record. So, if the record is a "Fail", the failed items will be added below the main group of labels; therefore, many child groups of labels will be added below the main group, which is theoretically the header record. I am using a second panel to add the failed items. My issue is how to dynamically add, name, and position the failed item labels and panels. Below, I have included a sample of what I am trying to accomplish.
View 12 RepliesI'm trying to add a group of four radio buttons to a form. There are other radio buttons so I'm grouping them by placing them on a Panel. However using the below I just get the panel added to the form without the radio buttons... Am I doing something wrong here?

The goal of this code is to add a control to a panel in runtime. This MUST be done in runtime for the purpose I intend. The problem is that, when I add a second control, the first one disappears.

I have a question in regards to the usability of panel controls (2.0 frameworks). I have a change request that I'm currently working on where the end user wants to see the data in a different format. Currently the data is only being returned in a weekly format, and now they want the data to also be returned in a hourly format as well.
The data is being displayed in a series of labels (child controls) that are tied to a single panel (parent control.) I would like to set the user up with a checkbox that they can use toggle the way that the data is displayed (weekly & hourly), but I would also like to use the same single panel control to display both views (weekly/ hourly). Is there an object associated with the panel control that will allow me to do this? If not then what would be the best approach for this change.
