Web Forms :: How A Browser Differentiate Between Server Control And Html Control
Feb 25, 2010
When a .NET server control is rendered in a browser it is rendered as a html control. Then how a browser differentiate between a server control and a html control. If the two control rendered as same then how server side events fire for a server control? If u say by using runat="server" attribute then also we can add runt="server" for html controls to work at server side... so then how these are recognized?
I am new to MVC framework. I am having issue as follows,I am having "txtUsername" textbox inside my view (myView.aspx). The same control also avialble in my usercontrol(MyUserControl.ascx).In my view i am rendering this usercontrol as follows
I am can able to access this both textbox in view and usercontrol in controller class as follows
ViewData["txtUsername"] = "Text from Controller";
Here how do i differentiate these controls. If i run the application both textbox from view and user control filled by the text"Text from Controller". I dont want to fill the text with view's textbox.
does anyone know how to access a webpart using the HTML Document Object Model? for example: for a given page which contains a webpart manager and a webpartzone.
[Code]....
I cant access the custom control using the HTML DOM Like this: HtmlDocument doc = HtmlPage.Document; HtmlElement element = doc.GetElementById("HostTest"); HtmlElement element1 = doc.GetElementById("silverlightControlHost"); HtmlElement element2 = doc.GetElementById("WebPartZone3"); HtmlElement element2Parent = element2.Parent; HtmlElement element3 = doc.GetElementById("SLRoomConsumerPart1"); //element3 does not return anything at all just Null!
all of the other elements are returned except for element 3 which returns a null! Any controls (regardless if it is a custom control, ASP control, Usercontrol . i tried it by replaceing the custome control with an aspnet button. i go t a null value as well) placed in the <ZoneTemplate> Tag of the <WebpartZone> is not returned using the HTML DOM. I find this stupid and pointless, as the whole point of a webPart is that you can place all sorts of controls in it : customcontrols, usercontrols html controls, html server controls, aspnet controls and you cant seem to get access to those controls using the HTML DOM model in codeBehind <asp:WebPartZone ID="WebPartZone3" runat="server" Height="90%" Width=" <ZoneTemplate> <cc1:SLRoomConsumerPart ID="SLRoomConsumerPart1" runat="server" /> </ZoneTemplate> </asp:WebPartZone> HtmlDocument doc = HtmlPage.Document; HtmlElement my_WeBpart_Element = doc.GetElementbyId("myCustomWebPartControl1") can anyone point me to a solution or a work around as i am trying to access the dom from silverlight 3 but should be exactly the same as doing it from the webpart'shosting page's code behind. so that i can reference the controls inside my web part from the code behind of the custom page once i get hold of the webPart Element referece.
Setting value in html control in code behind without making server control
<input type="text" name="txt" /> <%--Pleas note I don't want put runat=server here to get the control in code behind--%> <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
Code behind
protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack) { //If I want to initlize some value in input, how can I set here } } protected void Button1_Click(object sender, EventArgs e) { Request["txt"] // Here I am getting the value of input }
i want to know what is the main thing that differ between web server control and html server controlthey both run at server. Is the only difference is that, html server control are light weight??
I want to know: what are the basic differences between html server controls and web server control. As I have gone though lots of surfing but couldn't find the exact answer.
I need rft server control not HTML based server controls to display and store text as well as images, from which i can get rtf text and can save it as it is in DB.
I try to run each control and then check what html did it render.
But this seems to me as an inaccurate method as whenever we add or remove the properties, or events of the control,the rendered HTML changes. Is there any book/tutorial/article to explain what is the standard HTML rendered by each asp.net control.
is there any way to create a server control from html string, i mean in code behind i have a string like string html = "<asp:CheckBox ID="CheckBox1" runat="server" />";So how to insert it into aspx page and when the page is rendering, it convert my string
I am trying to create an HTML button that can use a C# server side delete function. since I don't know how many results I will have at the page, the control is created dynamically when the end user searches for current Messages: [CODE] CmsContactUsContent += string.Format(" "" + "" + "
I need to create a reusable custom control,which is like a form containing a listbox and some fields.The fields can be either textbox or combobox as needed for different applications,which can be selected on the property of the form onwhich page that i am using it,also i needed to specify the number of fields in that property.And also need place 3 buttons below for edit and delete the selected item in the listbox and a button to save.Data will be binded from the database as needed for different applications.
tell me with code how to create it using asp.net server control in C#.
I've a grid view which could have huge data. When any control like a button causes the postback, I do not want gridview data to post back as it is not required and results in slower responses.
I added a Input (Text) control in my web form and turned it into an HTML server control so its an instance of HtmlInputText class.
If I double click on the control It only adds a OnClick event handler method inside the script tags in the HTML doc of the web form but how to I get to handle its Serverchange event exactly? does VS.net 2008 has no ability to auto wire up the event to the control, do I have to manually wire up the event handler?
If a composite server control normally encapsulate styling information inside, it is an example of code encapsulation and modularization. However if css properties are included inside the composite control, it is not ideal for code/styling separation and css code re-use principles. Now which consideration should be the main consideration?
