VS 2005 - Top Of The Panel To Bump Up Against The Bottom Of The Custom Control?
Mar 23, 2009
I created a custom control. I put it on a form with Dock = Top. I place a standard Windows Panel below it and set it's Dock = Fill. I would expect the top of the Panel to bump up against the bottom of the custom control, but instead, it goes underneath it and jumps all the way to the top of the form. This behavior does not seem to exist if I place two Panels on the form and set one to top and the other to fill. The second one bumps up against the bottom of the first one, as I would expect. But my custom control (from UserControl) does not seem to work this way. Do I have to set something special on my control?
Namespace CustomPanelControl Public Class CustomPanel Inherits Panel Public Sub New() MyBase.New() [Code] .....
Now I need to use it and make it fade in and out. This is a panel containing typical play, stop, FF, REW controls over a media player. Just like Windows Player or VLC, I want the panel containing the controls to fade out on mouse leave and fade in on mouse enter.
I'm trying to create a simple transparent PANEL control. I want to create a custom control based on the existing Panel Control with a property added called "transparent" which can be set to true or false. If it's set to true it's transparent(not invisible). So if I place it over some controls in a form say a button or text box... they are visible but disabled.
I have inherited the standard panel control to create a panel having custom border color. The problem is, while the panel is on a form and any other form is moved across it, it paints hapazard lines of the same color as the panel custom border color, all throughout background of the panel. I tried to Refresh or Invalidate the panel in its paint event but of no avail. The same is happening while designing in the design editor too. See attached image. Why is this happening and how to get rid of it? My code follows:
I created a custom control and I'm trying to insert it into a panel, but also center it.The control itself is larger than the panel, so I've set the AutoScroll property of the panel to True. I think that might be affecting it. Perhaps I should just offset the Y axis a bit.But, either way, this is what I'm trying:
VB .NET 'Create the control Dim AutomationReport As New AutomationReportControl
[code]....
It works just fine with the X axis, but the control is out of bounds vertically. About 1-2 inches of the top is cut off.
I'm trying to create a custom control that contains a List(Of Panel). I quickly ran into an error about the base class Panel being nonserializable. So I created my own class that inherits from Panel and implemented the ISerializable interface. At the surface, everything appears to work, at least everything at design time. I don't know what would happen if I tried to run the application. Anyway, the errors occur when I try to open a file that contains my custom control. For example, I create a new Windows Form and add my custom control to it. I save the Form and close it.
Then I try to open the form and get the following error: Object of type 'MyTestApplication.SerializablePanel[]' cannot be converted to type 'MyTestApplication.SerializablePanel[]'.
I don't know what I'm doing wrong? I've opened the XML file to see what it's actually writing, and read the header notes about using binary base64 serialization. I think that's what I'm using, but I'm not sure.
Below is the code for the class SerializablePanel:
I have a question about getting control inside of a panel to appear Here's what I am trying to do:I have 2 database maintenance screens done with both details and grid.
Customer Inventory
I have all the Customer table data on 1 panel control (pnlCustomer) that has textbox and datagridview controls. The visible property is set to True because this is the first UI that I want to appear when the form loads Next I created another panel for the Inventory data (pnlInventory) and I added contols to that in detail and datagrid views. I placed the Inventory panel directly on top of the Customer panel. The visible properly is set to False My intentions are that when the employee selects the Inventory button that the Customer panel will hide() and the Inventory panel will show().
I have tried a number of things but they do not work. What happens is that when the Inventory button is selected the Customer panel and all it's controls will actually hide but the Inventory panel will not appear. If it is opening, then there are no controls visible...and I checked to make sure that the property of all controls in the Inventory panel are set to Visible = true
Here is what I have tried:
' on form load pnlCustomer.Visible = True ... also tried .show() pnlInventory.Visible - False ... also tried .hide()
This is a task panel made from 3 others open source code that I combined. It already has some docking ability, hiding ability, resizing and moving but there are some problems it wont dock top and bottom without getting confused with left and right. When 1 panel docks another panel will dock on the side of it not the parent container. It needs some kind of splitter container to be able to dock into if you have 2 panels or more docked on the same side but still being able to drag out of it and move somewhere else. So who wants a challenge here is the link to all the files [URL]
While implementing this article,i cant understand what they try to mean by this:Still in the Code Window, change the line that reads:Inherits System.Windows.Forms.UserControl So that it reads:Inherits System.Windows.Forms.Button..if i change this line of the designer form: Inherits System.Windows.Forms.UserControl to this: Inherits System.Windows.Forms.Button...then when i return to the designer,i am getting this error: The designer cannot process the code at line 22: Me.AutoScaleDimensions = New System.Drawing.SizeF(6.0!, 13.0!) The code within the method 'Initialize Component' is generated by the designer and should not be manually modified. Please remove any changes and try opening the designer again.
A friend of mine called me to that we need a program for our club that when a member will enter in club gate so first of he will have a card upon which a barcode will be printed and through barcode reader his code will be scanned and will be find out that whether he is a temporary member or regular member or absent member or other. Only regular members are allowed to enter into club and allowed to avail all services of club. Now the question is that i dont know that how the custom barcode will be created and how the scanner will be controlled with vb.net?
i created a custom control that accepts only datetime values. [url] but i'm having some issues with it when it is bound to a column and then i navigate through records. it seems to trigger a row-change to all navigated records even though i haven't manually change anything on these records.
this is affecting the last_update_date and last_updated_by fields of my tables. i need to only affect records that were manually changed. can anyone help me? also, any date field should be bound to the Value property of this control instead of Text. haven't figured out how to remove the Text from bindable properties yet.
I am trying to create a news ticker app that runs on the top of your screen. however, other forms get stuck under it(the topmost property is true). i need a way to bump the other forms from under it. i also need a way to keep people from dragging other forms under it. I NEED TO HAVE THIS PROJECT DONE IN 2 DAYS.
I have one form lays on the top of a form or a panel. I would like be able to drag the top form within the boundary of the bottom form or panel. How can I do that?
I have noticed in my applications that if I open several forms, one after the other, I end up with a load of icons at the bottom of the screen where the Start button is. Is there a way to group these so the main one only shows?
I have 8 tabs in Tab Control. I set 1,2,3,4 in first row and 5 to 8 in second row but my problem is that when I select tab 1 to 4. Then row is switched and its shows at bottom. Always selected tab row shows bottom I need to fixed it. When I select any tab, tab order remains same. I am using vb.net 3.5.
Public Function debugOutput(ByVal type As String, ByVal StringToOutput As String) As Integer Debug.Items.Add(type, StringToOutput) Return 1 End Function
For some reason only the 1st string appears(type) and StringToOutput doesn't appear at all. also how would i make a listview control automatically scroll to the bottom
I am modifying some code I found here to test to see if a user has scrolled to the end of the control. In this case the control is a Crystal Viewer but I posted here because I think the issue is based on the vertical scrollbar not the Crystal Viewer itself.
The code flags an error at
Me.CRViewer.Controls.OfType Indicating 'OfType' is not a member of 'System.Windows.Forms.Control.ControlCollection'.
I understand the concept that I can't reference something that it is not but I don't know how to fix it. The original code was for a DataGridView.
The ultimate goal (not finished) is to find out when the user has used the mouse or possibly the scroll bar itself and if it hits the bottom of the page of the viewer, then trigger a new page so it looks like they can just keep using the mouse to scroll.
Public Sub New() Me.InitializeComponent() Dim vscroll As VScrollBar = Me.CRViewer.Controls.OfType(Of VScrollBar)
How do I set a User control (or a class with a few properties) to appear in the tan bar at the bottom of the Designer? I have tried googleing it but, I don't know what that bar is called (Kinda Hard to Google without know what to Google)
I have custom collapsible panel control. I put it into a FlowLayoutPanel. he FlowLayoutPanel is docked within my form. The Panel Anchor property is set to Left/Top. The purpose of the anchor is so that if I want to put multiple panels in the FlowLAyout Panel, they will all stay snuggly together when they are expanding and collapsing. The panels work fine.
I have created a basic OS with VB.net and in that I have a panel docked at the bottom which would be my taskbar. My problem is if i minimize any forms or programs I open they all minimize to the windows taskbar. How can i make them minimize to my panel?
I've been programming a Fisheye-panel that holds image and make it behave like the icondock in Mac Os X. But now i have a problem. When i add to many item, i want them to shirk, to make room for more, or grow when i remove icons. This is the behavior i get: When i want them to grow, they don't grow at all. When i want them to shrink, they shrink, but leaves lots of empty space (like replacing a photo from a frame with a smaller photo. The image shrink, but not the frame)
I need to have a custom background on a panel that can be resized with the form and want to know how I should go about designing it. Maybe have three images the left side, right side and the middle is just replicated? The thing is I would like for it to have a border and there will be buttons attached to the top edge so simply stretching a static picture may make the buttons not line up properly.
how to specify a custom icon for display in the toolbox window when you create your own custom control? Something other than the dreaded "gearbox" icon.
I am fooling around with VB for a while now and it is not the first time I created custom controls to use in an application. The situation: I have a database application (FormView / not GridView). The form is designed the following way: At the left I have a Panel1 with TextBoxes and other controls to view / edit dataset records. At the right I have a Panel2 which contains on default a custom control (a number of PictureBoxes mainly) to view / add / delete pictures associated with the currently viewed data record.
On a ButtonClick at a special button on the ToolStrip, I would like to replace that custom control in Panel2 with another custom control (which contains a search with different search possibilities), so, I basically throw out the PictureControl and load a SearchControl instead. This is the first time where I actually designed the custom controls within the actual project. In past, I always developed the custom controls seperately in a new project and later imported the dll. However, my first attempt just does not work and I don't even know where I should start troubleshooting since I don't get any errors.
