Custom Server Controls :: Creating .NET UserControl With Collection-type Property?
Feb 21, 2011How 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:

C# - Dynamically Assigning A Property In A Usercontrol?
Dec 13, 2010I 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.
C# - Dynamically Setting Usercontrol Property?
Nov 17, 2010I 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.

View 1 RepliesWeb Forms :: Object Reference Is Required For Non-static Field / Method Or Property
May 7, 2015I'm using jQuery and setInterval method in my asp.net web application.
I call the webservice every 5 seconds in order to check for DB changes. When i see a change, i want to change the photo of the linkButton that located on the master page, but i can to that due to static constrains.

((Site1)Master).SetImageUrl = "~/Icons/a.ico";
}

UserControl, ViewState And Loosing Property Values?
Mar 29, 2011this is about ASP.NET, ViewState, UserControls and loosing the values of my properties. It is an classic question by know, I know, and even though I have searched here and on Google for a resolution to this problem, I havent succeeded. On the contrary, the more I test different things, the less I understand it seems.
On top of this I am using ext.net and their so called DirectMethod's but I dont think that has much to do with this problem. There are numerous questions I have and I hope that this text will be fairly readable and understandable =)
