I reference a user control in my ListView in this manner:
[Code]....
The problem is that the #Bind command doesn't update the database, but it does so when I paste the code directly into the aspx page (in other words, without the user control involved).
[Code]....
When i add this control to a page i set it's address with Address property. But it never sets it's address property like this :
[Code]....
When i try it like above, it always set address null. So it never goes to webpage that i want. It's result in the address bar always like this :
http://localhost:4533/TarihKoruma/?Date=12.05.2010 but i want it like this :
http://localhost:4533/TarihKoruma/Events.aspx?Date=12.05.2010
I made a composite control that contains a ListBox. I am using the Composite Control throughout my application but I can not bind the listbox in the Compositecontrol. I have setup a Public get to access my listbox in the composite control.
View 3 RepliesI have a custom user control UserProfileLink on which I have two basic string properties, UID and UserFullName which I would like to use in a template column in a DataGrid like this:
....
<ItemTemplate>
<td:UserProfileLink ID="uplUser" runat="server" UID="<%#Eval("UserUID") %>" UserFullName="<%#Eval("UserFullName") %>" />
</ItemTemplate>
....
I get an error saying "The server tag is not well formed" which leads me to believe this type of binding isn't possible. Is there a way to do this, or is it impossible?
I have a custom control which inherit from the Table class and in the constructor, it takes a an integer as an argument. There is no empty constructor.
Is there a way for the user to set that variable in the properties window after they drag the control onto a form.
I know some .NET controls, you can set the source for the parameter to different things like another control's property, QueryString using just the properties window.
Right now, I have to create the control dynamically. I read the query string and then created the object.
I have created a user control and am ready to convert it into a custom control. I am trying to follow:
[URL] the steps mentioned in the link.
I am not seeing Build / Publish Web Site option.
I am using VS 2008. I only see Publish User Control but it doesn't give all the settings mentioned below. When I do publish user control, it just copies the ascx file to the desired location. how can I convert the user control to custom control.
I need to develop control (template or user) which must have subtags with some items.
For example :
<SomeControl runat="server" id="scTest">
<column1>TestColumn1</column1>
<column1>TestColumn1</column1>
<column1>TestColumn1</column1>
</SomeControl>
This control may contain some other web server controls such as GridView.I need explanation of experienced developers, how to do that - take me to the right way
I'm new to all of this, so go easy on me. This should be an easy one. I have created a custom SmartContentBlock user control for a CMS.The control works, but only if I invoke the Fill() function in the Page_init event in the codebehind of the ASPX page. My goal is to modify the class file so that the Fill() in the codebehind is no longer neccesary. So, for reference, here's the gist of the current situtation.Controls.cs

I have a web user control that represents a simple message box. It is used to display simple messages like "Item has been deleted", or "The item was saved successfully".
On the other hand, I have another web user control that represents the item in the form of an editable form (I made this a user control because this is used in two different pages). I want to embed an instance of the message box user control inside the editable form. I am writing this right after the @Control directive:
[Code]....
Instead of using @Register directives, I register the user controls in web.config and so far this has worked just fine.
With the above markup, the project compiles, but whenever I try to navigate to a page that contains this construct, I get an HttpParseException exception. Furthermore, Visual Studio states that the tack w7rc9:MessageBox doesn't represent a known control.
What am I doing wrong?
I have 3 pages in each page there is a portion of page where it is common in all these three pages.Thought of making the common stuff as a separate control either User control/Custom control.Any suggestions on which one should i use custom/user control
View 2 RepliesI have a user control (ascx file) that contains an interface for users to change the data retrieved from the db. So, I am displaying data and most of this data can be edited by the user. When the user enters text into a textbox, and clicks "Save Changes", the value they typed in is lost and not persisted to the database. I realize now this is because the SaveChanges button does a postback, and the user control gets reloaded with its original valuesbefore the code within my SaveChanges button gets executed. I'm not sure if there are properties I need to set to save the input data, or if I need to write my own code to do it. What is the generally accepted method to do this? (Also, all of the controls in the ascx file are wrapped in an Update Panel.)
View 8 Replies i'm opening a new window and passing on to it variables in a querystring, the values are loaded into a function that is filling my dataset and then filling my Gridview. after i press the button field in my grid to delete an item, the databind doesn't show the updated grid but remains the same. i've noticed that if i navigate back and refresh i see it correctly. in FF btw no problem.

I am using two user controls in my page. The controls are loaded dynamically one at a time. I'm just referencing the user controls in the page and loading them dynamically using 'LoadControl()'. Everything is working fine till now and the user can switch the controls one another.
Here the issue I found is eventhough the controls are working as expected and the data is visible, the rendered HTML contains only the first loaded user control's markup.
Even if the current control displayed is 'usercontrol2', the source shows 'usercontrol1' markup. How can I force the page to render 'usercontrol2' markup and remove 'usercontrol1' markup while loading'usercontrol2'?
I want to create a completely new control instead of extending an existing one. I have found a few articles on the net, but it's not exactly what I'm looking for. I've created Custom User controls in Win Forms before and thought it would be somewhat the same in ASP.NET, but it does not seem so. Many articles talk about a Web Control Library template which doesn't seem to be available when creating a New Project, but is available when adding a New item to an existing ASP.NET forms project in VS2008.
I have extended control by using the ASP.NET Server Control template. But all you get with is a .cs file. How do design a brand new control with that?What I want is to create a control from scratch, with postback functionality, and that compiles to a DLL. Am I going about this all wrong? Should I rather be looking at the ASP.NET Server Control Project Template? If so, How do I create a brand new control with the ASP.NET Server Control?I'm working with VS2008 SP1, .net 3.5, and C#.
The built in Asp.Net Controls (label, Textbox, etc.) all have a CssClass property that can be set, what do I need to do to implement that for a Web User Control?
I know how to add a property and pass thru the get & set to the corresponding Asp.Net control (example if I have a label I know how to create a LabelCssClass property that provides a get & set, but the control itself how do I set a CssClass or ClassName property.
I have a piece of code that is just HTML. It was previously created as a user control. Within the application i'm working with there are two seperate websites that are interlinked to make one website. There is a documents section where users do not need to login and a data section where users need to login. The design was implemented long before I was hired. My problem is I want to use the code from the documents website with the data website but I can't seem to register the control. I only one this piece of code in one place so when it is updated it doesn't have to be in multiple places. I tried setting "src=http://website/doc/doc.ascx" but this errors out saying
<%@ Register Src="http://website/doc/doc.ascx" TagName="docs" TagPrefix="temp" %>
Parser Error Message: The file '/documents/http://website/doc/doc.ascx' does not exist.
It adds the directory as part of the src. How can I have it point to this location http://website/doc/doc.ascx ?
I have a templated user control with single instance template attribute. It works great for everything except the following scenario:
[Code]....
The folder selector uses a tree view that allows people to select a folder, its FolderSelected event works perfectly and the file selector updates with the files. The file selector has a repeater that lists the files in the selected directory. It has a linkbutton for each of the files so that the user can select a file. The problem is that the ItemCommand event of the repeater doesn't fire when the file name is clicked on. The page performs the async postback like it should, but in debug, the method to handle the itemcommand event is never hit. On the same user control to select files there is a button that the user can add files to the folder. When it is clicked, the event DOES fire and the file is added and the control refreshes in the update panel, everything perfect. It seems that because the linkbutton is already in a templated control (which is in a user control, in a templated control), the event isn't firing correctly. I am confused as to why this should be a problem, especially since all the other events (even the custom ones) fire as long as they aren't in another templated control. Since the code is complicated, I didn't want to post it all here.
I have created rounded template user control. The need is what ever we add in the user control should appear appear.

I'd like to create a user control which takes XML as input, applies an XSL transform on it, and displays the results of the transform in the web form or windows form in place of the user control. The transform should happen automagically when the windows form or web form is first loaded. I'd think this would be pretty easy to do. I just don't know how. point to a guide/tutorial on how to do this?
View 1 RepliesI would like to ask you what is the best practice for developing composite user web control with multiple controls inside from the stand point of dealing with properieties. In my situation I would like to use header menu bar with logos, buttons, java baset visible/hidden menus itc as web control. I was successfull in implementing new control in my project.
But my question goes to issue of properties for ALL OF controls. I know how to hard code all required properties like: text, visible, enable for all controls. It's a lot of work. ( This is the very edge of my asp.net comprehension ) Is there a more elegant way provide an access to controls's properties without hard coding seperatelly?
