Handling Dynamic User Control With JQuery
Mar 15, 2011
I have a user control which I am dynamically loading in my page_load event via a method (see below). The user control contains a gridview and a label. A key piece of information has to do with how to get around the convenient feature of gridviews not rendering when their datasource is empty. In my user control I add some hidden rows so that the grids will render and the user can see just the headers (if the situation calls for it).
The nomControl is an asp:Panel on the parent page which will hold the user controls. The dsRefinedProductsNomInfo is a strongly typed dataset.
[code]....
how I should be handling my events so that my rendered grid is up to date and not showing these hidden rows. I have a feeling I am just doing things in the wrong place/order but this is my first real swim in the deep end of the asp.net pool.

I have a User Control which consists of a TextBox with a few extras, but for purposes of this example just assuming it's a plain TextBox will be sufficient. I am calling this User Control from a Web Form and would like to be able to use a RequiredFieldValidator that basically would function the same as if I used it on a TextBox on the web form. How do I configure my User Control to handle this?
EDIT:
DatePicker.ascx
<asp:TextBox runat="server" ID="myControlTB">
DatePicker.ascx.cs
[ValidationProperty("Text")]
public partial class DatePicker : System.Web.UI.UserControl

I am part of a team that is developing a SharePoint web part. My task is to create a user control which will ultimately be wrapped in another class for presentation in a web part. Because of these requirements, I must fit all of my code in a single user control.To organize my code in the code-behind, I created a few private classes for the different objects which are represented in the database. I want to add some exception handling whereby if some sort of DB exception is thrown I can update a message on the page informing the user of the problem.
My problem is that the page-level controls are inaccessible from the private class where I'm issuing the query, so even if I catch the exception I have no way of directly accessing a Label control to populate the error. I tried to create a baseclass with an EventHandler defined, but when I throw events from the private class I'm not able to catch them for whatever reason. I'm far from an OOP expert Here is a snippet:
ASP Code:
using System;
using System.Collections;

I have a custom ascx user control on my page that includes a dropdownlist. There is an onSelectedIndexChanged event handler that is connected to this dropdownlist. The first time the user selects a value, the page does a postback and the logic executes correctly. However, if the user then goes to change their selection, the event handler does not get triggered.

I have a user control called ucTriStateButton. It raises an event when it is clicked, called TriStateButtonClicked. If I put this user control on a page, it works fine. Here is the declaration on the .aspx page:
[Code]....
When the button is clicked the method tsbTest_TriStateButtonClicked executes correctly.
The problem is when I put the user control in template field of a GridView.
[Code]....
There is no way to hook the event handler to the control in Page_Load because I cannot get a reference to tsbMorning. So I did it in the RowDataBound event handler of the GridView, where I also do a bunch of other row-specific stuff. Although this builds and runs, the event is never actually subscribed to and so never gets fired.
So the question is - how can I handle an event from many instances of the same user control within a GridView? I am calling the same bit of code regardless of which user control is actually clicked. I only need to know that one was clicked.

i developed a custom control (inherited from System.Web.UI.UserControl) which is used within a Gridview's TemplateField:
<sc:MyControl
runat="server"
id="my_ctrl"
AllowEditing="true"
NumberOfControls='<%# Eval("Count")%>' />
"Count" is an integer value from the GridView Datasource.
Based on this value i have to create some LinkButtons dynamically in my custom control (in Page_Init), which works very well when the value for NumberOfControls is hard-coded.
My problem is that the value of "Count" is not available (NumberOfControls = null) during Page_Init and therefore i can't decide how many controls there should be generated.
Is there any way to pass databinded values to custom controls so that they can be used earlier (as if the values were hard-coded)?

I'm developing a CMS of sorts, and I want to give my users the possibility of customizing the display. More precisely, I want to give them the ability to choose to display or hide the left column, the right column and/or the top div. The middle column cannot be hidden since this is where the actual content will show, whereas the other columns are for navigation or side menus.
I've been looking for a way to make this as smart and flexible as possible. For now I'm using a MasterPage, but that seems to be too constraining. For instance, with MasterPage you need to add a ContentPlaceHolder control in every of your ASPX pages.
What are the best practices in this area? I guess a simpler way of saying this would be "I want to create a template system over which I have complete control".

In one of my ASP.NET webform application I want create dynamic controls and add Event handlers for those dynamic controls..For example when I click a button I want to display a list box and I want to add
SelectedIndexChanged event for that list box.I have errors in doing this... Here's the code I tried out... I think there are errors due to my lack of knowledge in postback
[Code]....
[Code]....
DLabel is a existing label control...*** When I click the button I get the ListBox... When I select the Item 1 the page reloads and nothing is displayed in the Label.

I have the usual problem of dynamically created usercontrols not hitting the event handler for a linkbutton inside the control, but I've checked the usual problems and I can't work out what's wrong. I'm calling a function to create the controls at the bottom of my page.load (although I did try page.init as well just in case) outside of my page.ispostback check, and I'm setting the controls id's to a fixed name which is consistent across postbacks. Any ideas what's wrong?

I am not sure how to do this. I have part of it working and I think I understand why it isn't working, I just not sure what I have to do to fix it... I am dynamically placing some data into an ASP:Table from a DataSet. This is all done from the Page_Loud event. I am looping through the dataset by going through the rows no problem to display the data in cells added by rows to the asp:table.
What I am also doing though is adding a button for each row that is to run an Access insert query that adds a record in a log table.I have used the following code to get this to work which it does, most of this is called through functions in the Page_loud event. this is the gist of it:
this is in a loop of the DataSet
for (int i = 0; i < dsResult.Tables[0].Rows.Count - 1; i++)
{
Button btn = new Button();
btn.Text = strDynamicText;
intTID = dsResult.Tables[0].Rows[i].ItemArray[5].ToString();
[Code]....
Here is the problem I am having. The button does display for each row, and the query does execute and run when I press the button. The values being passed in intTID and intUserGroup (are global), are suppose to be different for each row though, and are to insert a unique table ID, and a different group depending on what is in the dataset. Problem is, it is only assigning the last tableID from the result set into the button and will always pass that same ID no matter what button is pressed. This is the same with the intUserGroup. It needs to dynamically have differnent table IDs passed but that's not happening. What do I have to do differently to make sure that when the button is created dynamically it will pass the unique values for each row?

I want to dynamically add a web user control to a web form. Everything I've read so implies that I should be able to use the PlaceHolder web server control for this, yet I cannot this to work. I've created a simple test to just try to master this concept, yet I can only get non-web user controls added. Can anyone tell me what I'm doing wrong? Below is the entirety of my code.

I created a customDropdown usercontrol with Events and It worked fine.
Now I stored the path of the ascx file in the database table and i want to Load the ascx file and handle the Events dynamically in an aspx page.
To Load the usercontrol and access the public properties and method, I need to know the object i am trying to load, right?
For Example
FeaturedDDL c = (FeaturedDDL)Page.LoadControl("~/FeaturedDDL.ascx").
But I dont want to hardcode objectType "FeaturedDDL", coz i dont have that stored in my Database field.
Since I am loading the usercontrol by getting the path and name of the usercontrol from the database table,how will I know the ObjectType at that time?
How to accomplish that and also how to handle the events for these type of situation?

so I have this custom user control, just some data inside divs with a fancy css.
So inside my page I need to add it multiple times, and I do so in code behind within loop.
Now, this code doesn't work
[Code]....
and of course it works fine now. My questions would be - why? can I do it without pecifying file name and just creating control the normal way like in first example?:S

I have a user control (i.e. ascx) that comprises of two related list boxes (i.e. once you change the selected item in one list the contents of the other list update). I'm adding this user control dynamically to a page on the click event of a button (i.e. using LoadControl).I wish to set the list box datasource properties, as well as the default selected item of the parent list from my parent page so I created public properties in my user control to accomodate this. I also created an event in my user control that notifes the parent page when the selected item changes in one of the list boxes so I can update the contents of the other list box.
I understand that I have to recreate the user control on every postback in order for it to function correctly but I'm not sure exactly how I should be doing it. I've shown below what I have currently - whilst it works the problem is that on postback I'm always creating the user control with all its default properties and then updating the properties that need to change(?). For example, when the choice in theparent list box changes the datasource of the list box is set twice (once in AddControl and then again in OnParentChanged)? As the contents of the list boxes originate in a database it means I'm making unnecessary calls to the database (unless I do some something like store each unique set of data in the ViewState).
I'd be very grateful if someone could review how I've done things and illustrate how perhaps I should be doing things. I'm not sure if the way I've done this is considered the 'correct' way. For example there may be a better way of doing things would avoid setting the properties twice? I'm a bit unsure of the way I've set the datasource properties of the list boxes and bound them. I wished to set the datasource from the parent page because I might have a second user control on my page that may also use the same datasource and I could reuse it (as opposed to each control making its own call to the database) so I'd like to keep this feature if possible.It would be great if posting code in reply that you use my example as a guide so I know what you're referring to.Here's the code for my user control:
