writing a code for adding a dynamical user control to the static web part zone.
I need to add, <uc5:FckEditorModule ID="FckEditorModule1" runat="server" /> dynamical to the webpart zonetemplate.
I have a page that has 5 zones, by default have also defined the layout.
Now I need to restrict the user to have only one web part control in a zone at a time. Is that possible? Currenty we can add more than one control in the same zone.
I m new in web part tools in asp.net, i create a simple page using web part tools, but now i want in my web part zone too open a web site like I Google..
when u use i google there is a functionality to open a web site in web part zone.
specify method to remove web Part Zone names.
View 3 RepliesIs there any way to restrict a web part to a certain zone? I know I can restrict it by using the AllowZoneChange flag, but is it possible to make sure the web part can only be added to certain zones? I have some web parts which are only viable in a wide column (zones), so I want to make sure that no one tries to add the web parts to narrow columns (zones). Is there any way of accomplishing this?
View 1 RepliesI created user control and want to add it to page. I use next code:
Controls_MultiTextInput cc = new Controls_MultiTextInput();
Controls.Add(cc);
But control doesn't appear on page. What is wrong?
I am having a .net project that builds the web based installer. I was using visual studio 2005 environment and the project is targetted to .Net 2.0 framework earlier. I don't see any issues with installing the product that was builted from above environment.
Recently i migrated to Vs2008 and .Net 3.5 framework and the i was facing the following issue. During the installation the web browser( opened in IE 6.0) is getting opened in INTERNET Zone which applied higher security settings including disabling of all Java scripts.The browser was not responding any click events( next or back or cancel).Copying the URL to the new IE doesn't have this issue. I am not sure whether it is an environment issue or not.
When in the Catalog Zone, I select a Web Part and a zone in which to put it and then click Add. I need to know immediately which zone has been selected in which to place the selected Web Part.
My Catalog Zone is declaratively a class called CatalogPart1 which inherits the CatalogPart class:
[code]....
But I cannot work out how to use this event to get the Zone that has been selected.
How do I get the Zone that has been selected?
I have created a user control as part of an asp.net web application. This control works fine. I have then moved the control into a class library and attempted to reference it in my original application. I find that the asp controls created in the ascx for the control (texboxes and buttons) are no longer instantiated i.e. I get a null reference exception in my Page_Load event handler when I try to reference them. The only change to the page in my original application has been to change the register statement to load the control libary dll otherwise this is identical to when the conmtrol was part of the application:

I'm building an HTML5 application (with ASP.NET back-end) and i want to develop it in such a way that i can run it locally with all my resources (such js and css) not minified (so i can debug it easily). However when i build the final version i want merge and minify the resources. At the same time i want to create several versions of the app targeting different platforms (iPhone, iPad, desktop, etc) by adding appropriate css.
I thought that the final output should be a set of html files (so the get cached nicely). I could use ASPX and just control the output by a query string parameter, but i don't really want to have the form tag on my page.
So the questions are:
What are the pros and cons of using static html pages generated from a template versus a dynamic ASPX page? (apart from being able to run on any web server)
If ASPX approach good enough then how can i get rid of the form tag that's required by ASP.NET?
UDPATE
Another factor in favor of static html pages is the fact that the files are served instantly, whereas ASPX may take awhile to load if the app has recycled.
The back-end is ASP.NET 2.0.
I'm trying to implement a plugin system, where plugins are in a form of ascx files with code in dll files.
I created a WebApplication project called "UserControlLibrary" that contains one user control "TestControl.ascx". The output from this project are files UserControlLibarary.dll and TestControl.ascx.
Then I created a WebApplication project "WebApplication1" that will use the TestControl.ascx and UserControlLibarary.dll (both files are placed in the "Controls" directory of WebApplication1).
I'm trying to dynamically add the control in "WebApplication1":
[Code]....
Unfortunatelly i get the exception: Could not load type 'UserControlLibrary.TestControl'The problem seems to be in a placement of UserControlLibarary.dll. When it is in the bin directory of WebApplication1, everything works fine but when it is in the "Controls" directory then the exceptionis thrown.I tried to solve this issue by adding the following code, with no success (the event handler is never called):
[Code]....
So my question is how to put UserControlLibrary.dll in a custom folder (in this case "~/Controls" folder).
I have a web app hosted with GoDaddy (so the web server is in Arizona - Mountain Time). My users are mostly in Central Time Zone, but I could have some from other time zones. I have a web page with a databound dropDownList using TimeZoneInfo, and I want to set the selected value of this dropDownList to whatever timeZone the user is in. Here's my code currently:
protected void Page_Load(object sender, EventArgs e)
{
DropDownListTimeZone.DataSource = TimeZoneInfo.GetSystemTimeZones();
DropDownListTimeZone.DataBind();[code]....
It's ok, but I want it to be smarter for those users who aren't in CST. I was hoping there is some way to grab the user's TimeZoneInfo from something like Page.Request.??
whats the exact use of static variables in overall programming in .net and for asp.net...
Recently i went for the interview where interviewer asked me 2 question which i was not sure for the same..
whats the use of session object, i said sessions are the server side object, they are used when you want to store user specific data at server side, then he asked what if i want to use static variables for the same, i was mum, can anyone tell me how asp.net will behave if i store the user specific information in static variables.If i use cookies which are the best option to store the data at client side (not sensitive one), but what if user has disabled cookies on his machine, will my application would crash.
I have a few pages that are completely static. They only change at build time. But they are expensive to create. For the ones that are kind of expensive to create, I cache them for very long times using the ASP.NET output caching. But for one page, I really want it cached forever and ever or until the the next build.
What is the most expedient way to make this happen? Is there a build in feature that achieves this or a 3rd party tool?
(yeah, for the moment I plan to do the "view source" and copy paste thing, which isn't a very elegant build step)
I'm new to Web Part programming in ASP.NET...I have created a simple sample website, containing a page with a WebPartZone control (and other necessitites).After I ran that web page and logged in, I closed all the Web Part controls that the WebPartZone contained. Now they are all gone when I re-visit the page and log in.
How can I regain the Web Part controls of that WebPartZone without coding anything? Do I need to add some particular Web Part Zone control or something to the page? Adding a CatalogZone control was of no use. It only seems to list Web Parts that have been explicitly assigned to it at design time (or by coding).
I have four columns in database. Consider it as a,b,c and d. I'm trying to place a and b column values in TO part and c and d column values in CC part in outlook. a,b,c,d contains six digits numeric values. I just need to place a and b columns values in to and c and d values in cc part on click of a button.
View 1 RepliesI have a multi view which contains a view which contains a panel. the name of this panel is "Panel1"I have the following code and my HTML does not display in the rendered page. Any idea why this isn't working, i must be doing something wrong? sw = simple html statement, any would produce same result.
String mstring = sw.ToString();
Panel1.Controls.Add(new LiteralControl(mstring));
i am using dotnetnuke also, not sure if that is where the issue is.

However this doesn't work,I get the following error:Object reference not set to an instance of an object.
Highlighting:DataList1.DataSource = ds
If I take the loginview away then it works,but I thought the loginview1.findcontrol part would solve any problems.
my MasterPage I have a label that reflects the name of the module that the user is currently in. I change the label text accordingly using the following ..
private void ChangePageTitle(string PageTitle)
{
Label lblPageTitle = (Label)Master.FindControl("lblPageTitle");
lblPageTitle.Text = PageTitle;
}
Instead of placing this method in the code-behind of every page, I want to put it in a single class and call it accordingly. I thought of using a static class but do not know how to reference the MasterPage.Can I use a static class? or do I place the method in the code-behind of one page and call Object.Method from the other pages?
I don't think I understand fully how ASP.NET does inheritance of controls.I have a user control, ucBase, which has an asp.net label in the ascx file. Code behind references the label and it works fine during run time if the control is not a parent for another user parent.
If I have another user control, ucChild, inheriting from ucBase, the label in ucBase's code is always null. ucChild has no controls in its ascx fileThe server controls (like the label) needs to be declared in the ascx file and not created programmatically.What needs to be done for ucBase to see its own controls when it's a parent user control?
I read an article on the www.4guysfromrolla.com which tells to store gatetime in getutcdate() in the database.and while displaying use javascript
