I'm using the VS 2010-Net 4.I have develop an usercontrol that is compiled on one DLL and when I reference this DLL in other applications the usercontrol doesn't look like it was desined. It looks all wrong.
In the same project of the usercontrol if I put the control inside of a form there looks the way it supose to but in other projects as reference doesn't.
I have a user control in vb.net application.and i have a form in vb 6.
so in my vb.net applciation to this user control i need to mention the vb 6 form as its parent.
Means when i run a vb6 application i should see this user control as a part of that form.
I have a customer which as a Visual Basic Project in single instance mode with a wired presentation logic.
The main form contains a TabControl with mutliple TabPages.If I click on TabPageA another form is shown in front of the Form and resized to have the same size as the TabPage.
If I click on TabPageB the first form is hidden and another form is displayed.So basically for the user it looks like you have a TabControl with different TabPages which is not the case.
I tried converting the Forms to UserControls and put them inside the TabPage, but, thanks to the SingleInstance app, this would take a whole lot of refactoring. I tried it but eventually gave up because of many many runtime errors and I don't want to put any more effort in this.
Am faced with the above problem which I have failed to understand. the details of the error are given below.
Code:Control 'ValidationSummary1' of type 'ValidationSummary' must be placed inside a form tag with runat=server.

I have a DataGridView in one of my form which at a certain point I resize an change it's position. I would like to be able to restore it to the designer's default position at runtime. I know I could save it before changing and then restoring it later, but I feel like there surely is a way in .NET to just restore a control position to it's default.
View 2 RepliesI am developing a software using microsoft visual studio basic 2010. I used a datagridview control to display a list of data from product table. What I want to do (actually I am not sure how to do it, or is there a way to do it), when I choose one of the value in one of the column inside the table, I want it to open a form that contain data(details) based on that value.
How to do it? How to call the value that I pressed, so it can be used to open a new form containing the details of that value
Example of the data: (the "system" column) SYSTEM
topaz
nex1300
Nec
If I pressed "topaz" system, it will prompt me to a new form containing the details of that "topaz" system.

I am making an invoicing application. I have a label (lblCost) inside of a UserControl (InvoiceEntry) inside of a FlowLayoutPanel (pnlEntries). InvoiceEntry represents a line item on the invoice, and pnlEntries is the "body" of the invoice. pnlEntries can hold several InvoiceEntry controls.
I am attempting to sum all of the lblCost values from each InvoiceEntry control to make a subtotal, and I want that subtotal to change automatically if costs are changed (e.g., a change in quantities being ordered). Is there a way to handle when the lblCost.Text property of any of the InvoiceEntry controls contained within pnlEntries changes?

View 4 RepliesI have an asp.net usercontrol which represents a "popup" dialog. Basically, it's a wrapper for the jQuery UI dialog which can be subclassed to easily make dialogs. As part of this control, I need to inject a div into the page the control is used on, either at the very top or very bottom of the form so that when the popup is instantiated, it's parent is changed to this div. This allows "nested" popups without the child popup being trapped inside the parent popup.
The trouble is, I can't find a safe way to inject this div into the page. A usercontrol doesn't have a preinit event, so I can't do it there, and calling Page.Form.Controls.Add(...) in Init, Load or PreRender causes the standard exception "The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases."
I thought I had found a solution by using. ScriptManager.RegisterClientScriptBlock(Page, Me.GetType, UniqueID + "_Dialog_Div", containerDiv, False) which seemed to work well normally, but recently a coworker tried putting an UpdatePanel inside the dialog and now she's getting the error "The script tag registered for type 'ASP.controls_order_viewzips_ascx' and key 'ctl00$ContentBody$OViewZips_Dialog_Div' has invalid characters outside of the script tags: . Only properly formatted script tags can be registered."

View 3 RepliesI have a form allowing user to search details of employees. the form allows users to key in 7 search criteria. the results of this search open in a new window. employee details (data) are of following 3 types: personal details contact details additional details
I want to achieve the following with the results window the new window that opens to show the search results has a tab control with 3 tabs for displaying the results for each of the above categories. hence the three tabs would be personal details contact details additional details each tab would display the required data in a datagridview control. on adding the datagridview directly to the tabpages of the tabcontrol the window does not resize to the size of the datagridview that is displayed. i understand that the property AutoResize is not applicable to a tabcontrol or a tabpage, hence 1 added a panel to each of the tabpages and then added the datagridview to it.
However, even this does not help and the results window is still does not resize to the size of the datagrdiview. i have set the AutoScroll property of all the tabpages to, AutoResize of the datagridview and results window all to True. How to do this as the results widow does not rezise even to the size of the tabcontrol that i have added and the tabcontrol ends up with scroll bttons in the window.
I think the short answer is you can't, but there has to be someway to make it happen. I want to make a list of items, that then have a list of items within them, nesting only one level.[code]...
