Web Forms :: Creating A Nested Property In UserControl Or Multiple Child Properties In Parent Property?
Aug 2, 2010
Can anyone add a complete input about how to create Parent Property with multiple child properties or in short nested properties.
Example: Style tag: which has properties like font, color, display... etc? which accept objects and its value.
[code]....
As soon as Rainbow property is typed, user should get intellisense for list of number of colors. Then accordingly user can select list of those colors and assign a value to them.

So what I'm trying to accomplish is this
[Code]....
The user control has public properties named accordingly and the page has protected properties accordingly which I've verified have the desired values.
For some reason the values are always empty strings or 0s in the usercontrol, no matter what the page property is.

How can I create a UserControl with a collection-type property which has a collection editor?
I've a CompositeControl with an ArrayList-type property which has CollectionEditor-type designer. You can see this property on Properties window with a "..." button which launches a collection editor. This works fine and all but I want to apply the same to a UserControl and I've couldn't manage to pull it off so far. I've done the same thing what I've done with my CompositeControl but the property either doesn't even show on Properties window of the UserControl or shows as a single value property with no "..." editor button.
This is what I've done with CompositeControl:

I have several usercontrols which are loaded based on business logic.However, all of them have webcontrols whose selected/entered value needs to be accessible in parent page on an event.Since there can be any combination of UserControls, I do not want to load all the UserControls in the Parent Page, since they are heavy.
I would like to load only those controls which are supposed to appear on the page, yet access the value from the usercontrol which caused the postback. (I would rather not access using Request.Form) (ViewState is open, but unsuccessful to store value in parent page's viewstate in onClick)Here is a sample scenario
Page: Home
Dynamically Loads: UserControls1
UserControls has TextBox tb and Button btn, causing onClick
When btn is clicked, I want to get value of tb in parent page on PostBack, Page creates UserControl2

If for example my userControl has a CheckBox called IsGreatCoder and the userControl is embedded in a main page (parent page).
I normally have gained access to the IsGreatCoder.Checked value in the main-page by exposing it through a public property that I have to manually write (say "IsAGreatCoder").
If UserControl is included in the main page as "userControl1", then I would access it as "userControl1.IsAGreatCoder".
But, I was wondering if there was anyway to declare the UserControl such that all the UI controls added to it were declared as being public, that way allowing me to gain access to the actual controls in the main page (the parent).
Essentially I would like to be able do something like userControl1.IsGreatCoder.Checked instead of having to implement a property.
The reason I want to do this is that I want to have access to many more of the check-box's properties and it would be a pain to implement each one as a public property.

Here is how I use the control in a gridview on the host page:

I'm having difficulties with adding sub-properties into Property sheet.
for example:
let's say I've created a web-control with a textbox in it. I can add to my web-control a new property such as:
public TextBox MyTextBox
{
get
{
return m_TextBox;
}
set
{
m_TextBox = value;
}
}
and this will be enough for me to add the TextBox into the property sheet of the web control each time i use this web-control.
My problem is with adding the TextBox properties into the property sheet with the sign "+" next to the "MyTextBox" property.
I'm using VS2008 if it's make the difference.

I need to read a Property/variable from outside the webpart usercontrol to determine a course of action. This is not the same as using the Property Editor.
I have numerous usercontrol webparts all accessing the database.
When minimised, I don't want the webpart to hit the database.
So, I need to either : detect within the usercontrol webpart itself that its chromstate is minimised and therefore not access the database (and)or from the Webpartmanager loop through webparts, determine those that are minimised and set a variable / property within the webpart to inform it not to access the database on postback.
Something like...(pseudoCode)
for (int i = 0 ; i < webpartmanager1.webparts.count ; i++ )
webpart wp = (webpart)webpartmanager1.webpart[i];
if (wp != null)
if (wp.ChromeState == PartChromeState.Minimized)
{
// set a known variable in this particular webpart so it can determine whether to refresh its datagrid or gridview or whatever
}
}
OR
Can a usercontrol webpart determine its own ChromeState ????

I have a nested gridview containing gridviews: gvMaster(Parent) and gvAlternate(Child)
If I select a row in gvAlternate is there a way for me to find out what gvMaster row it is under? I want to highlight the selected gvAlternate row and the gvMaster row that it is under.
[code]....
I can get a certain set of rows of gvAlternate only by referencing which gvAlternate control set I want to access: this is based on the gvMaster.Rows and then using the FindControl and id name:
GridView
gv = (GridView)this.gvMaster.Rows[aRowNumber].FindControl("gvAlternate");
Therefore, it is true that a set of rows in a nested gridview is tied to a specific row in its master gridview, the question is does the child gridview know which set it's connected to or does it's master know if a childset has been selected?

I am having trouble finding how to solve the following issue :
I am using nested listviews to display Sales and Sales details.
The main ListView displays General Information about Sales and the child ListView displays the detailed information about one sale. the child listview is shown only when the user clicks on a link (see included code, DataBind is made on PageLoad) :
ASPX Markup Code :
[Code]....
C# Behind Code :
[Code]....
If I removed the datapager part, I can manage show/hide the child list view on the button click event. but if I want to use the DataPager with the PreRender event handling, the child listview is not longer shown on button click.

I currently have a repeater control and inside the itemtemplate I have a usercontrol. This usercontrol renders correctly, but I am trying to assign a dataitem to a property in the repeater control.
[code]...
RequestId is just an Int32. It just doesn't assign it.
I can put the eval outside of the usercontrol just in the itemtemplate and it correctly outputs the right id.
If I remove the whole eval and just type a number in then it works fine. I was using an EntityDataSource and this automatically binded to the repeater. It printed out all the information from the database on the screen without any codebehind. But when I put in the code behind Repeater1.DataBind(); it then started to work.
I don't know why, but hey it's solved. It now successfully passes the value through. I imagine it has something to do with the page lifecycle.

I have a user control in asp.net that i need to dynmically set properties for. The propety and property values are in a dictionary, for example:
Dictionary<string, string> propertyValues;
Control c = Page.LoadControl("~/Control.ascx")
I can currently set the properties on the control using reflection, however, with .net 4 and the new dynamic keyword, is there an easier way to do it, for example, something like this:
dynamic c = Page.LoadControl("~/control.ascx");
foreach(var itemin propertyValues)
{
c.item.key = item.value;
}
this obviously doesnt work because item.key is a string and not a property.

I've got a [PageDefinitionTypePlugIn] PropertyString (it's a dropdownlist), and I'd like to be able to detect what it's parent page is. Generally, Global.EPDataFactory.CurrentPage works fine to return the page, but when a NEW page is being created, CurrentPage returns null.I need to know prior to the render of the control what the parent is, since I'm changing the list of values in the dropdown depending on where the current page is in the navigation heirarchy structure.
