Web Forms :: Custom Control Bindable Property Lost Value After Postback?

Mar 24, 2010

I am using: .NET 2.0, VS2005

I customized a button from System.Web.UI.WebControls.Button (it is a Custom Control, NOT an User Control, no ascx file)the intention is to adding a OrderID property to the button, that can be bound to a datasource field.

Here is how this control is used in a aspx page:

[Code]....

Here is my definition of the MYButton class, it saved in a .vb file and placed in App_Code folder

[Code]....

Here is the code trying to use the OrderID in btnSave_Click()

[Code]....

The problem is OrderID is always returned as 0.

When first time page is loaded, and gridview is bind to a data source, I step through the code, and the OrderID property are set correctly, but after the postback caused by the button, the OrderID value has lost.

Forms Data Controls :: Property Of Custom Control In Repeater Is Null On Postback?

Jan 12, 2011

A common problem in repeater controls where you want to display data for update (like a list of user phone numbers that can be updated and submitted back to the database) is where to store the database unique row identifier. So, I created a custom Textbox control that I've added a Data property to. I populate this data property with the unique row id. The problem is that when I post back the list and go through the repeater items the control's data property is null. The custom control looks like this:

[Code]....

The tag in the repeater looks like this:

[Code]....

I have a custom checkbox with the same data property and it works fine. I actually put in the same repeater with the textbox control and the checkbox control have the row id on postback but the textbox did not. Is there some limitation on the textbox control that might be causing this.

Accessing Property Value Of A Custom Control By Another Custom Control In Design-time

Oct 18, 2010

I created an Extender which has a custom property that drills down a list XML elements from an xml file, where users can select xml elements during design-time. This works perfectly fine. However, my code only has a hardcoded xml filename (source of the xml elements list) and I need to change this by maxing the xml file user-specified.

What I did is that I created another control (panel) which has a custom property that when clicked (through the ellipsis), it will allow a developer to select the xml file which is supposed to be the source xml file that the Extenders shall use. The filedialog from custom panel's property works perfectly fine.

However, my problem now is that when I drag-drop my Extender, I cannot find a way to get the property value of the custom Panel Control which contains the xml filename. I tried creating a static variable which I thought the custom controls can share but VS2010 is breaking.

Custom Server Controls :: List Property Of A Custom Control Is Not Persisted?

Mar 15, 2010

I have a custom control, inherited from Button. This is the class definition for the control and 2 properties:

[Code]....

I show you 2 properties, only to illustrate the problem.

as you see Aplicacion property is of a custom type Sistema, and Roles property is of type List<UserRol>.

The Aplicacion property is rendered well, this way:

[Code]....

The problem I have is with List<UserRol>. I couldn't get it to be rendered. I expeect to be rendered this way:

[Code]....

Finally, this is the TypeConverter and Editor definitions for the list:

[Code]....


The UserRol class is a typical class, without any special attributes.

I have discovered that when I use the custom editor for Roles property, the collection is not persisted. When I use the default editor for the collection, the collection is persisted.

Web Forms :: Modify Property From Custom Control

Sep 29, 2010

I'm trying to do something which to me seems like it should be simple, yet I cannot think of a simple way to do it.

I have a built custom control, that has a property I want to change based on a user's interaction with a second custom control. This second control will be a table of data, with an 'edit' link in the last column. I would like the control, when the edit link is pressed, to pass an ID and trigger some event so that I can assign this ID to the first control. My initial technique for building this (second) control was to create some code which will iteratively create some html based on a dynamic range of data selected by the user. I know that I could create some sort of link with a value in the query string, but I would like to implement AJAX and was hoping that I could enable this communication without changing the URL.

Web Forms :: Restoring User Control Property Values Upon Postback?

Jun 9, 2010

I'm constructing a User Control that will have one Property called "ContractIdx". Here's how I've constructed this Property:

public int ContractIdx
{
get
{
return Convert.ToInt32(this.Attributes["ContractIdx"]);
}
set
{
this.Attributes["ContractIdx"] = value.ToString();
}
}

I'm initially loading the User Control by passing a parameter to it and setting ContractIdx accordingly. That all works fine.

Upon Postback though I'm loading the User Control without any parameters and then setting its ID property to what it was before the Postback. My understanding was that if I did this then ViewState would properly restore everything. Yet apparently this is not the case with the "ContractIdx" attribute.

Where am I mistaken in my understanding? How should I change things to get this mechanism to work?

Custom Server Controls :: Custom Control's Children Do Not Persist Contents After Postback

I have created a really simple custom control to render panels into a page. The code is below. When I use my control and add any webcontrol to it, after each page postback the contents of these child controls vanishes.

I must have missed something really simple but run the example to reproduce this. Can anyone please enlighten me as to why the controls are being 'emptied' of their contents, and how I stop this occuring?

Here is the code for the control

Web Forms :: Trying To Reproduce GridView.Columns Property In Custom Control?

Mar 9, 2010

I'm working on an ASP.NET 3.5 project that requires me to create several custom navigation server-side controls that can be customized at design time by non-ASP.NET website developers through a simple text editor. All but one were relatively easy to create, but the last one is stumping me. I've looked online and can't find any examples anyplace that come close to what I'm trying to do.The last control needs to give the site developers the ability to manually define the number of nodes that are displayed within the control when it's rendered on a page, and I want to reproduce the design time/runtime functionality of the GridView's "Columns" property. In the Columns collection the site developer at design time can manually specify the look/feel of each column within the ASPX designer. I want to give my site developers the same design-time flexibility so they can add/remove nodes at their whim and not bug me to do it for them.
an anyone point me to any examples of how to create a collection custom child controls that are associated with a custom server side control?

State Management :: Update User Control Property On Postback?

Mar 31, 2011

I have created a user control with a property named CurrentPage. When a link button is clicked it runs PostbackToPage() and passes a command argument in which then sets the CurrentPage property with this new value. On the page which uses the user control I am trying to display the updated CurrentPage property after a postback. When I click the link button to cause the postback the CurrentPage is the default value. However when I click it again it works as expected. So it seems to only work after 2 postbacks. How can I get this to work after the first postback?
