View 2 RepliesI have a question about creating and managing events inside an ascx custom web control.
I have created a very stupid control consisting in a div containing a asp:Label control, it is a very simple structure:
<div id="mydiv" runat="server">
<asp:Label id="mylabel" text="Text"... />
</div>
That is, very simple.
I would like to add an event: clicked. I want to let the user add this control on the page and attach handlers to this event so that when this control is clicked it is possible to do something. It might seem a strange solution, it's like i'm trying to invent again the button control, that is: my custom button.
Well to fire the event I would like to add a javascript in my div and call a js function that calls, using ajax mechanism, a server side function. Well how to call a server side function from here.
I posted a question about how to call a server side function from a client side one and got some answers (many of them told me to use PageMethods), well it seems that pagemethod does not work, it compiles but when running and clicking on my control and executing the js (in the line PageMethods.mymethod()) here I have an error --> Java script exception: unrecognized method. It seems not finding the PageMethod.
getting an error like this:

I need to create Listview control dynamically and also i get columns dynamically .
How can create dynamically LayoutTemplate and ItemTemplate and how to bind data dynamically.
I'm using Visual Studio 2008, and when I select/highlight something in design view and switch to source view it does not highlight and scroll to the selected item. This makes it really hard to change stuff in source view, and it's very inconvenient at worst

View 2 RepliesI need to use radio buttons in a datarepeater. The problem is that radio buttons do not get the same ID in repeaters, so cannot be mutually exclusive. One way I read about getting around this is to create my own radio button and just render it differently.
I am trying to create a server control that inherits from the radio button. It needs to support postback and async post backs and have event handlers. The code I have works fine, in the sense each radio button is mutually exclusive but events are not being fired.server control:
Code:
<System.Security.Permissions.PermissionSetAttribute(System.Security.Permissions.SecurityAction.Demand, Name:="FullTrust")> Public Class NewRadioButton
Inherits System.Web.UI.WebControls.WebControl
Implements System.Web.UI.IPostBackEventHandler

View 1 RepliesWhen using the "add view" dialog in vwd is there a common practice for presenting any primary key fields as readonly to the user in the view?
By default it appears the user could change the key field value (as it is presented in a textbox) and overwrite data for that record for which the key was accidentally changed to.
Do we have to store the original record's key and then make the key presented as a label and then on the update subtitute the original key value back in for the record? Or is there something simpler?

View 1 RepliesI'm stumped after a few days of searching and trying to create a Data Source to Oracle for a report under Visual Studio 2005. I followed the guide at

I am able to connect through the Server Explorer to our Oracle database using both .NET Framwork Data Provider for Oracle and Oracle Data Provider for .NET. I can execute queries on both of these and retrieve data.
The problems start when I try to create a data source under the Solution Explorer. I have created a Business Intelligence project on my local computer.
Data Source Wizard Select Create a data source based on an existing or new connection. Click New... Here the Provider is disabled and it appears defaulted to SqlClient Data Provider. All I can do is connect to a MSSQL server.
How can I connect to an Oracle database here?
I'm creating a web server control that has an image button on it.The html for the control is done in the RenderControls of the code, the control devrives from WebControl, IScriptControl, INamingContainer.The button is coded as follow in the RenderControls:
System.Web.UI.WebControls.ImageButton img = new System.Web.UI.WebControls.ImageButton();
img.ImageUrl = "Url of the image";
img.Click += new ImageClickEventHandler(img_Click);
img.ID = this.ClientID + "_img";
img.CausesValidation = false;
imgLock.RenderControl(output);
The button apreas in the browser but when i click on it, the page postsback but the event handler for the button doesn't get fired, from what i can figure out, since the control goes throught RenderControls eachtime the page is posted back, the button gets redrawn and the event handling disapears.
I want to be able to do something like this
<test:TabControl id="" runat="server"....>
<ItemTemplate>
<tabItem label="tab1" />
<tabItem label="tab2" />
</ItemTemplate>
</test>
The idea being here is that the only acceptable items in "ItemTemplates" are the tabitem types. There are many asp.net controls that use this, for example the ScriptManager class only allows you to specify certain types of objects under its various collections. Maybe thats the key to this.. I want to add a collection as opposed to a template. The idea is that in code I will then iterate over each "tabItem" and create the tab as I want it to look (probably rendering div's etc). Ive had a look at most of MSDN link on how to create templated controls but it doesnt seem to do exactly what I want it to. Would be grateful for some assistance.
I'm making a html document by using a StringBuilder, the document is used at a messageBody for a email.

The image is available from the site, I've tried pasting the address in the browser and the image shows up fine.

View 6 RepliesI want to create a map control which will be a server side control.I want to have it as a tool in the toolbox. The above control will contain providers that will fetch maps from the following sources:
1) WMS
2) Oracle Spatial DB
3) Google
4) MS Virtual earth.
How to create the providers for the different map sources? Then I hav to create different screens which will take the parameters and send them to the map preoviders. The map providers will send the generated map to a map control (could be a active X control) or something else. The map control should also be capable of performing standard functions like pan,zoom etc. Pls give some idea as well as source code on how to start with it.
I've been using the Item Inserted event for my data controls, such as details view. I'm wondering if there are advantages to doing this with the data sources instead of the data control. There is a lot of overlap in the events provided by these two types of controls. Are there advantages to using the events raised by the data source instead of the ones raised by the data control itself. Should I be using the events raised by the data source instead of the control used to enter the data?

where I can start learning how to do this, or offer direct help on the code? I've read many tutorials for creating controls using existing controls (e.g. custom labels etc) but they are all too simple. With the above, do I need to create a ContentArea control first, then work onto the TabbedControl? How do I get ASP.NET to render out the contents of my ContentArea (including ASP.NET controls that are contained within it)?
