I'm trying to develop a web application where there webpage would contain a list of Web control (textbox, label, calendar...) images on the left (as a menu), and the user would be able to drag any of the images onto a specific space within the page and it would dynamically create that specific control (for example, if the user drags an image of a TextBox into a panel, then a TexBox control would be dynamically created into that panel). Basically, I need to reproduce the basic drag-and-drop functionality of an IDE. To be honest, I have no idea how to do this.. anyone can point me in the right direction??

Forms Data Controls :: Create A Placeholder For Drop Down Lists?

Aug 25, 2010

I'm using VWD with a database back end. I have a list of teams which are marked off by league, level, division, teamid and then using gridview for the list of players per teams.I've got the drop downs working correctly but running into a little snag and that is on the auto postback.When I only have one option come up in a list, i obviously don't change that list and thus it doesn't change the next drop down because there is no post back. is there a way to use a "header" value?

What Is The Best Way To Display A Hierarchy Of Choices In A Forms Application

Sep 13, 2010

I am working on an ASP.net Forms Application that keeps track of information about different offices in an organization. The offices are organized into a hierarchy.

Some users of the program will have access to certain information about all offices in the hierarchy. Some users of the program will have access to only a small part of the hierarchy.

When a user browses for information they are authorized to see, I would like to present the user with a prompt to choose which office in the hierarchy they wish to see information from.

I want to accomplish the following:

A) I want the user to be able to easily navigate the hierarchy of the organization to locate a specific office.

B) I want the user to be able to navigate the hierarchy without refreshing the page.

C) I want my interface to be able to handle a hierarchy at least four layers deep with less than 100 nodes.

I see that Microsoft includes a TreeView control in the standard collection of ASP web controls.

Web Forms :: To CtrB (the Correct Hierarchy) Its Not Working.

Aug 19, 2010

I,m having some issues with 3 user controls.heres the scenario.i have 3 UserControls: ctrA and ctrB and ctrC.the idea is: ctrC is collections of ctrB plus some minor info and ctrB is a collection of ctrA plus soe other minor info.ctrA is a simple control with 2 textbox and a label.u enter values on the textbox and the label shows the values multiplied by each other.ctrA is totally inside a updatePanel and when i drag-and-drop it on a custom-page or to ctrC it works just fine (notice that im breaking the disired hierarchy).but when i add it dinamically to ctrB (the correct hierarchy) its not working.the page is being posted back synchronously and worst,the controls desapear.like if they were never there.

Web Forms :: Accessing Controls In A Hierarchy Of Nested Master Pages?

Dec 3, 2010

I have a master page. This is where I put my ScriptManager control.I have a nested master page within the master page.I have a content page within the nested master page. This content page needs to register a Postback control with the ScriptManager, but I can't figure out how to access the ScriptManager. Both Master.FindControl() and Master.Master.FindControl() always return null. I also attempted to use a strongly typed master page, but like all controls, the ScriptManager is protected and thus inaccessible from the content page. How can I access the ScriptManager?

Create An Image With Drop Shadow On Text Programatically In VB.NEt?

Nov 1, 2010

I'm currently building an intranet engine for a project I've got on the go at the moment, and I'd like to save myself a little time by generating header images from code where possible, however, I'd like it to match our concept image.What I'd like to achieve is below:My issue is I've not the faintest how to create that from code. I can do the absolute basics but that's about it.

I start to fall down when it comes to the gradient background and the drop shadow on the text. I can get away with positioning the text on the larger header image, so if it's not possible to generate the exact gradient I have there, then I have a work around for that, but what I really want to achieve is the text with the font and drop shadow.I'd say it's safe to assume that to use a "non-standard" font, I'd merely need to install it on the web server?
