I have MDI parent and child windows that were working fine but now clicking on a dropdown doesn't do anything, also scrollbars cannot be moved. Other controls are still ok, buttons and other links are still working. I should also note that if I change the child to load in a separate window all the controls work again.
View 2 RepliesEssentially, in C# the left dropdown has all the classes in a file while the right drop down has all the methods, events, properties, etc.In VB all of my controls are in the left dropdown and I have to select them if I want to go to a particular event handler for that control.I find it time consuming to navigate to my btnSave_Click method by first selecting btnSave in the left dropdown and then selecting Click in the right dropdown.Is there a setting or a plugin that can change this functionality?

I've got a MenuStrip with dropdowns and a Toolstrip with buttons. I don't want the button images in the image margin of the dropdown because they are too small to read properly. I can't seem to find the ShowImageMargin property (in either the MenuStrip or the ToolStripMenuItems) to turn the margin off. I've constructed the menu items in the designer.
I have set it up to email me should someone submit this form and an error occur and right now should that occur for most integer or datetime fields if they fail to validate then it will show me which fields in the email failed and what was input into them.
Problem I'm having now is to validate the drop downs and the textboxs in a similar way to what I with integer and datetime fields so I can display those also in the email in case they error.

Summary:- Need vb code to validate if strings and dropdowns are valid and the use of try/catch block is another possible solution but I wasn't able to figure out how to implement validation for that either.
I have one page with two dropdownlists with different IDs and in my codebehind I have two distinct methods, one for each dropdownlist, with distinct names and handlers.BUT, in my codebehind, only one dropdownlist calls it's method - and sometimes it calls both methods! - while the other dropdownlist never calls its method.I tried cleaning the infamous "Temporary ASP.NET Files" folder I tried rebuilding the solution but the problem persists?
View 1 RepliesMVC 3 VB.NET razor. I have a view that has 4 dropdown boxes in it.. This is for setting up a staff member.. If that staff member is to work certain classes then that class will be set for each day. If he is not then the value needs to stay null. This is a edit view so it may have to be accessed multiple times and still keep the original selectlist values if none changed. The below is what I have right now that is working only on its face. The Old selected value is shown first. However this isnt being returned on the save. The only way that it will save correctly is if I select the value that was set in each box then click save. The next problem is that not all staff members will have classes to work on every one of the 4 days. So how do I set a value to null and keep it that way unless a class Is actually selected.

Any resolution to make the cascading dropdowns work as expected when used inside edit mode of AspxGridview. I am using DevExpress Controls.
My requirement is as follow:
If I select country="United States" then populate the "State" combobox and on selection of "State" populate the "City" combobox.
If I select "country" other then "United States" then populate only "City" combobox with cities of selected "country" and no need to populate the "State" combobox. Also I need to hide the "State" combobox. i.e. like
Country State City
ROW1 united states Alaska Douglas
ROW2 Canada Toronto
ROW3 Australia Sydeny
ROW4 united states California Yuba City
Same is required in Editmode also.

View 15 Replies[Using VB.NET 2010 / targeting the .NET 2.0 framework]I'm getting some unexpected behavior with panel scrollbars, and was wondering if it is a bug, or simply something that I'm failing to do correctly.Basically, I have a panel with Autoscroll enabled. Then I put some other items inside the panel, and then make the panel smaller, so that the panel's scrollbars appear.
Outside of the panel I have 2 buttons -- named "scrollOn" and "scrollOff", which turn the panel's scrollbar's on and off using the "Autoscroll" property (for example the "scrollOff" code I'm using is Panel1.AutoScroll = False ).
So after I run the program, I move the panel's scrollbar down a little bit with the mouse (this part is necessary to reproduce the bug). I then click the "scrollOff" button (which should make the scrollbars disappear). But when I do that, the scrollbars are not only still visible, but they "freeze up" (can't move them with the mouse anymore).

View 1 RepliesI have 2 richtextboxes on a form and I want to link their vertical scrollbars i.e. ifrichtextbox1's scroll bar is moved then richtextbox2's scroll bar moves by the same amount.The reason for this is that both richtextboxes will contain almost identical text barring a few differences in the second richtextbox. By linking the scroll bars my hope is that the user can better compare the textboxes for any differences between them. I have looked at trying to find a scroll bar property but can not find one. Does one exist?

I have a LIstView to display four columns. I have fixed the width of LIstView to 400 and this width is divied proportionately amongst the four columns . The code is working perfectly. The problem is with the horizontal bar on the bottom of LIstView.

I searched the forum for this and couldn't find anything. Maybe someone can help me on this.I have a child form that has a ToolStripConatiner that holds a ToolStrip, StatusStrip and a PictureBox. I need to have scrollbars when the picturebox is larger than the form. I set autoscrollbars to true on the form but after I added the toolstripcontainer, the scrollbars no longer appear.
The toolstripcontainer is not docked but is anchored to the top,left,bottom and right. I tried unanchoring from the right and bottom, but still no scrollbars.
Does anyone know of a way to make the scrollbars appear, or maybe I am doing this all wrong and can give me a clue.It all works like I want it to except the scrollbars do not appear anymore.
I'm trying to use a loading overlay on top of a Windows form that adds a 50% opaque layer on top of a windows form with a loading GIF, while it does what it needs to do in a background thread. The overlay is a windows form that I'm drawing in the onPaint event.
The loading overlay works fine on multiple different form loads, but fails to work properly when summoned to ensure patience during a 30 second upload process (That Prints a Word Document to PDF, then uploads that PDF to a SQL Server). This upload collects some data from the form, puts it into an Object, then operates entirely on a background thread. The loading overlay will appear, show the first frame loading GIF, then just freeze. The onPaint is getting fired and the image frame is being updated, but it isn't visible
Constructor sets the form to be UserPainted:
Sub New()
InitializeComponent()
SetStyle(ControlStyles.UserPaint Or ControlStyles.Opaque, True)
End Sub

i have a number generator which creates a number then a new line followed by another number. its set on a timer that goes over and over again until a desired number is reached. the only problem is that the numbers go off the screen and a scroll bar appears but stays at the top. is there a way to set the value of a scroll bar on a text box and if not how would i tie a vscrollbar to a textbox or richtextbox.
View 2 RepliesSometimes, I have a picturebox lets say 100x100. But the image it will display is actually 100x400. I don't want to increase the size of the picturebox itself. Instead, I would like to create a vertical scrollbar (or horizontal if needed). I could not find a scrollbar in the toolbox, so I guess I have to code it. But, how? And I still wonder if I didn't make a mistake and didn't see the scrollbar in the toolbox.
View 3 RepliesI wrote a Visual Basic program using the PMT function to calculate the monthly payment for a loan. Also calculate the Total of All Payments made over the term of the loan. This is how it should work, The user will input the loan amount in a text box. The user will use horizontal scroll bars to input the term of the loan (years), and the rate of the loan. As the user clicks the scroll arrows for years and rate their values display on the form above each scroll bar. When the user clicks the Calculate button the program will output values for the amount of the monthly payment and the total of all payments for the term of the loan. The two scroll bars are set to their mid-points (15 years and 10%), I am unable to get to show this values in their respective text boxes for some reason. [Code]
