I'm developing a form with usercontrols which have to be edited during disign.The project has a connectionstring in de my.settings.The usercontrol has a property which is also called connectionstring.Now, I want to pass the project connectionstring to the usercontrol connectionstring, when the usercontrol is dragged to a form. (All during design)
View 2 RepliesI'm creating a usercontrol with a splitcontainer. I can reposition the split when running, but when designing on a form I can't adjust the position graphically, I can only do it by typing a new SplitterDistance. Is there a way to get a grip on that position at design time?
View 10 RepliesI have a TabControl on a UserControl. I want the UserControl to behave like a TabControl as usual (it contains only the TabControl and a Contextmenu), including Design-time behavior.I have spent the last two weeks finding out how to add the Design-time behavior and I think I have come a far way.The problem is with adding TabPages during Design-time (while the UserControl is a custom tabcontrol, it is using regular windows forms TabPages).In the Designer class, I have the following code to add a TabPage:
vb.net
Dim dh As IDesignerHost = DirectCast(GetService(GetType(IDesignerHost)), IDesignerHost) If dh IsNot Nothing Then Dim i As Integer = tc.SelectedIndex Dim name As String = GetNewTabName() Dim tab As TabPage = TryCast(dh.CreateComponent(GetType(TabPage), name), TabPage) tab.Text = name tc.Controls.Add(tab)
[code]....
So it would add the control to the TabPages collection if it was a TabPage, and use the regular routine otherwise.
(I'm now using 'tc.Controls.Add(tab)' again instead of 'tc.tabCtrl.TabPages.Add')
But, I don't think the designer even gets that far because it is telling me I cannot add TabPages to my usercontrol, because only TabControls can accept TabPages... How can I make my usercontrol understand that it is a TabControl (without Inheriting from a TabControl?)
I have a custom UserControl that I am hosting inside a FlowLayoutPanel. Each time that I run the application the control will disappear off the hosting form's design view. I have to close the form's design view and then reopen it each time. The control is not getting removed in any way, just isn't being shown.
Edit, alright this got a bit weirder. Only the first usercontrol that I put into the FlowLayoutPanel disappears. This problem also happens on a project Build and Rebuild.
I'm trying to create a UserControl in ASP.NET to display news items based on two values that are passed in, NewsTag and ItemLimit. The problem is that the SQLdatasource is not picking up the properties in SqlDataSource1_Init. Instead the calls to the properties are empty when this is called but after render have values.

in VS 2008, is there a way to design a ContextMenuStrip in a designer without a relation to a specific Form or UserControl class? For example,if you need the same ContextMenuStrip in Form1, Form2 and Form3, in which of them am I to design the ContextMenuStrip? Do I have to add a "pseudo-Form" to the project that contains my shared ContextMenuStrips and create only one instance of that Form, or is there another way? I consider this a programmatic hack, that's why my question is whether the IDE offers something better.

using VS2008, targetting framework 3.5I have a rather complex UserConrol which does some of its own rendering.I display this UserControl on a form.Opening that form in the Designer creates an instance of the UserControl in the Designer, which tells me a NullReferenceException is occurring in one of my rendering methods.I have attempted to correct this by making alterations to the UserControl's default constructor, but have not found success.

I have a form with 2 dateTimePickers and a SHOW button which gets data from an sql server database and displays it in a DataGridView. this works ok. I also have an EDIT button which brings up another form with textbox and comboBox controls displaying this one record. I want to be able to click in the DataGridView to select a Name and then click on the EDIT button to bring up the selected record. I don't know how to pass the ID as a parameter to this second form. Apart from that the EDIT button works, in the sense that I hard coded the ID (32 or 35 etc.) and it brings up the appropriate record. But how do i pass the selected ID. [Code]
View 2 RepliesI have a DataSet1.xsd This is connected to my access DB through OleDB. the DataSet Designer is stating that my column in my table is of type Double. Which is true when I verify it by opening Access and viewing that same column in my table.
I need to pass a parameter to my fill query so that on formload it populates the controls. I create the parameter in the dataset designer and give the paramter a name and specify the proper data type.
I edit the query to include the parameter.
on form load the generated code from the dataset designer inserts the fill command for the table adapter but doesn't include the parameter data, so I manually insert the data to be passed to the parameter.. This is where I get an error stating that datatype mismatched..
However the datatypes are correct.
[code]This works fine and passes 8 parameters into the sysimp.bat file. The problem is if I try to pass in a value that has a space between the text then it will treat it as two parameters rater than one.So if P1 value is for example "Hello World" then when passed into the bat file it will assign "Hello" to P1 & "World" to P2. Is there a way to wrap the text in the parameters or should this be done in the .bat file?

Currently working on a web-service with Oracle10g as back-end. Here is my problem.
1. The table I need to populate has 100 columns. I have no control over the design of the table.
2. I wanted to use the "deriveparameters" method of OracleCommandBuilder, but found out that this is "costly" in terms of performance. What I initially planned to do was to derive the parameters from an open connection, close the connection, then maybe cache the parameters obtained but I don't know if this is possible.
I am unsure how big of a hit the performance will get if I continue using the "deriveparameters" method WITHOUT caching the parameters driven. The environment is as follows
-intranet
-around 2000 users
-users spread out in different parts of the country
I am not familiar where they will put the web pages of the application, the web service and the database. I don't know if they'll be putting it in different servers or on one server, but that's something we cannot control too, that's why I am looking for the best approach.
I just don't want to hard-code all that parameters and if, for instance, we need to change some properties/parameters, it will be a pain to maintain the code. It would be nice if someone here can point a way to automate the whole thing w/o the performance of the system taking a hit.
