I would like to convert some aspx code in user controls. This would lead me to having a master user control that contains other controls inside.
The contained user controls have datasource with some control parameters that takes the value from a control present in the aspx (now) and that will then moved in the container user control.
which is the best way to handle a scenario like this?
I have a scenario where I've created a custom control that connects to a database and gets records from the last X number of months where X is any desired number. I use a "MinDate" parameter to determine how far back to look.
When I add my control to my page, how can I set the "MinDate" parameter to something like "DateTime.Today.AddMonths(-3)"? I've tried:
MinDate="<%= DateTime.Today.AddMonths(-3) %>"
I have a custom control that I have created. I want to be able to pass in a Javascript snippet for a callback function. I am able to do this by passing a string back. The problem is that in the Javascript, I need to reference another server control that is not related to my custom control. So, I need to be able to pass in the ClientID of that control for use in the Javascript. Here is a snippet of what I am trying to do:
[Code]....
Now, I realize that '<%= chkStartDate.ClientID %>' will not be parsed. But, I need it to be parsed so the OnClientOnChangeEvent property of my custom control can take any Javascript for use as a callback. In this instance, I need to pass in the ClientID of the control for the Javascript function to find the control to work with; and this seems to be the one issue that I don't know how to handle.
This may be elementary user control stuff, but I can't get it to work.
How can I pass the Membership.GetUser.UserName variable (or any variable) through a user control parameter at load time?
[Code]....
The only thing that I was able to do was to create the User Control object in the code behind and then add it to the page. Although that works, it doesn't seem like the correct way to program.
I tried both, loading the usercontrol when needed and I also tried adding it directly into the aspx.
Nothing worked. With the second one (what's meant to be the easiest option) I tried with delegates and events (but can't access de usercontrol event from page) and tried with properties (I can access properties but they're always empty)
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 want to pass to my control a value to one of its parameter of type DropDownList. Something like:
<uc1:MyControl Id="01" runat="server" OtherControl="ddl1" />
Where "ddl1" is a DropDownList defined in the same page my control resides. How to create this kind of property?
I 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 RepliesI have a 2 page signup form, on each page the form fields are seperated into sections. Each section is a user control, and there are 2 controls on each page. My question is, how do I get the data from page A to B. I'll be using a webservice to insert the data into SQL so I'm not worried about that portion of the process.

using System.Collections.Generic;

First, I would like to apologize, the search on the site wasn't working, so I don't know if I'm missing an existing post or not.
I have a web page that uses a master page file. I am using a third party control from Component One(TabStrip), the tabs are rendered as links on the final page. When a tab(link) is clicked, I need to load the appropriate web user control associated with that tab. Each web user control has its own post backs and methods. I know that I can load the controls on the "SelectionChanged" event of the TabStrip control, but then any postback created by the web user control that is loaded causes the page to refresh and the control was never loaded in viewstate. So, I tried to put my procedure of loading the web user control into the page_init method. This would work, if I could read which link was clicked on from within the page_init method. I tried using a javascript function to run "onclick" of the tabs and within it setting the value of a hidden control. I have verified that the javascript works and that the hidden control's value is getting set correctly. When I get into the page_init method, the value of the hidden control is not readable.
I'm tying to understand the page lifecycle to the fullest, but I don't see what I'm missing here. I know that I need to load the web user controls in the page_init method in order to persist the page as a whole, but how can I get which tab(link) was clicked to know which control should be loaded?
Header controls like create ,delete are created by using templated user controls (ITemplate) .
The controls are working in all pages except the last page when paging is enabled in grid view.
I have a user control with a textbox and a gridview. When data is entered into textbox it has to get data from the database and populate in the gridview. The grid view has add,edit and delete events.The user control is loaded dynamically multiple times on to the page.My issue is when i have 2 or more user controls and if textbox of usercontrol1 is changed, it reloads both the controls and fires the postback event of textbox twice each for the user control, where as it has to execute only once. due to which the data modifications in the grid are lost as it pulls back the data once again from the database.
View 3 RepliesI 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.
Basically I want to call a user control from a master page. However, I need to pass an object (a List of objects to be more specific), to the user control. I'm generating the list of objects in the Page_Load of the master page. Here's the line in my master page that calls the user control.
<cu:Eventlisting1 runat="server" id="eventListing1"></cu:Eventlisting1>
This user control has a parameter called CalendarItems that accepts the list of items. However, if I try to set this inside of the Page_Load method, my control executes before the Page_Load and throws an exception saying CalendarItems is null. Is there any way around this?
EDIT: I have a drop down list on this page that determines what the list of CalendarItems is so when I populate the CalendarItems list I need to be able to read the selected value from the drop down list.
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 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 want to create user control that can be added on other site.
here is the scenario.In my web site reservations can be done for restaurants. I want to provide user interface for reservation in restaurant owner's web site. When user goes to restauarants site he can reserve the slot through my site.
I've been trying to find a solution to compiling css and images into the dll file for distribution, but I haven't found anything good about it. The reason is pretty simple:
1. If the user doesn't use styles, it'll look like...manure ;)
2. If they don't use images, the shadowing effects will be gone
I will add features for changing the styles, but I would like to have a fall-back. If you don't have any ideas about the css, I can write it directly in style attributes instead of using classes, but classes are preferrable.

I am trying to build a custom composite control, which allows me to add custom content to each child control. It's a similar concept to what you have with a GridView and TemplateColumn. The markup used to place the control on the page would end up being something like this:
[Code]....
I have the code below, which allows me to put that markup on the page without throwing any errors, and it renders all the correct HTML, except it doesn't render the contents of the ColumnTemplate. I have replaced the Render() code with a comment because it's quite long winded and doesn't add anything important here:

I have tried to follow examples on MSDN and other forums but I can't make this work. I think I'm missing the code to render the contents of the template, but I don't know how to hook that up.
