How to Dynamicly generate HTML from server side ?
I'll give you some examples..
Now im using Response.Write("<a> hi hi </a>"); something like this and i generating stuff dynamicly depends on what is on the SQL..
I was wondering how facebook does it or all those sites is generating a full page depending on the SQL...
I have a page with a table and two button with the names (Submit and Add Rows) When I click on Add Row a new row will be added to a page(This is achieved using javascript), when I click on submit button I will be doing server side validation. If I found any error the error will be displayed on the page. During this process the controls which were added by me were loosing its state. As a result I need to add the rows once again and need to fill the data and click on submit button. Can any one let me know how to avoid this and see that the controls donot loose their states. So that there is no need for me to create rows once again if any validation fails on the server side.
View 1 Repliesafter trying alot and searching here and there i decided to post it here. I have my aspx page. at the top pf that page a html header is included, that html header contains a html select control with runat="server". i populated it with dataset, i also implimented onserverchange even successfully. no on my main aspx page i have anothe asp dropdownlist control. what i want is that whenever dropdownlist server selected index changed the value of html select control in my header also chang. I code in dropdownlist_selectedindex change like this
htmlselectcontrol.Value=dropdownlistcontrol.selectedValue.
but value of htmlselect control remains unchanged.
I am trying to integrate URL.... I am selecting urls of 3 images from database and and displaying those 3 images from a particular album. Now the problem is that what if the user has multiple user? It should be able to generate as many Jquery albums on the page as there are in the database associated with that user.
<div class="image_stack" style="margin-left:300px" runat="server" >
<img id="photo1" class="stackphotos" runat="server" clientidmode="static" >
<img id="photo2" class="stackphotos" runat="server" clientidmode="static">
<img id="photo3" class="stackphotos" runat="server" clientidmode="static" >
</div>

I was interested to know whether or not asp.net is allows us to dynamically generate HTML inline on the .aspx Source page (not the code-behind). For testing I created the following simple .aspx page...
In my asp.net code-behind I have the following:
protected List<string> myList = null;
protected void Page_Load(object sender, EventArgs e)
{
if (myList == null)[code]....
Notice that the Repeater control did in fact create the four list items. However, the contents (One String, Two String, etc) of the myList list did not come along for the ride.What do I need to do to evaluate the myList list and get its values inside the list item tags? By the way, I'm not concerned with how to use the Repeater control specifically, so if there is a solution to this problem that does not include the Repeater control, I'm fine with that.
Note: I'm aware that I can bind the "myList" generic list to an asp:BulletedList and get the same result. I am more interested in dynamically creating HTML inline of the Source page.
Is it possible to use AJAX and an update panel and create server-side controls such as checkboxes, buttons, and radio buttons (asp server side) that is created when another server-side control (that which exists outside the update panel) calls them?
secondly, how do you keep them from re-appearing after a postback?
When I do a postback, the controls in the update panel disappear.

View 2 RepliesI coded in code behind to dynamically generate a gridview as the columns of the gridview changes based on user selection. In the gridview I have dynamically generated controls like textbox, dropdown list etc.I have a few filtering options about, for example: listbox which will postback on change and causes the gridview content to change as well.My problem is: since the controls are randomly generated and every postback will read dataset from database and reload, the naming of the controls are dynamically generated too.

I have an ASP.net page which contains some controls.
I generate this controls by code, [Actually I have a method which uses a stringBuilder and add Serverside tag as flat string on it]
My page shows the content correctly but unfortunately my controls became like a Client-side control
For example I had a LoginView on my generated code which dosen't work, and also I had read some string from LocalResources which dosen't appear on the page What Should I do to make my generating method correct
here is the code
protected string CreateSubSystem(string id, string roles, string AnonymousTemplateClass, string href, string rolesContentTemplateClass, string LoggedInTemplateClass)
{
StringBuilder sb = new StringBuilder();
sb.Append("<div class="SubSystemIconPlacement" id="");
sb.Append(id);
sb.Append(""><asp:LoginView runat="server" ID="");
sb.Append(id);
sb.Append(""><AnonymousTemplate><div class="");
sb.Append(AnonymousTemplateClass);
sb.Append(""></div><asp:Label ID="lblDisabled");
sb.Append(id);
sb.Append("" runat="server" SkinID="OneColLabel" meta:resourcekey="lbl");
sb.Append(id);
sb.Append("" /></AnonymousTemplate><RoleGroups><asp:RoleGroup Roles="");
sb.Append(roles);
sb.Append(""><ContentTemplate><a class="ImageLink" href="");
sb.Append(href);
sb.Append(""><div class="");
sb.Append(rolesContentTemplateClass);
sb.Append(""></div></a><asp:HyperLink runat="server" CssClass="SubSystemText" ID="lnk");
sb.Append(id);
sb.Append(" NavigateUrl="~/");
sb.Append(href);
sb.Append(" " meta:resourcekey="lbl");
sb.Append(id);
sb.Append("" /></ContentTemplate></asp:RoleGroup></RoleGroups><LoggedInTemplate><div class="");
sb.Append(LoggedInTemplateClass);
sb.Append(""></div><asp:Label runat="server" SkinID="OneColLabel" ID="lblDisabledLoggedIn");
sb.Append(id);
sb.Append("" meta:resourcekey="lbl");
sb.Append(id);
sb.Append("" /></LoggedInTemplate></asp:LoginView>");
sb.Append("</div>");
return sb.ToString();
}

I've got a little situation here. I'm currently developing a site and the client would like the auto completing behavior. Basically not a problem as this exists, until I stumbled upon the fact that I'd also need to be able to generate this same control server-side.
Basically I've got a few pages where this control is added to the ascx controls and it works fine. However for conformity's sake that input should be the same everyhere. However, I do have a certain control on a page that is generated server side completely and I need to get auto complete behavior into that somehow.
Basically my current attempt goes a little something like this:
[Code]....
The second issue I came across here is that this is a .cs file in a class library. Therefore I cannot just put the asmx file in that folder and have it point to the physical path like the sample website. I was wondering if there's any other method of having the control contact the webservice (which is running in the main website in the same manner as it is in the sample site). Something I can define on the control server side.

View 4 Repliescan generate server control to html befor load page?
wanna replace HTML code to my content.
i need generate html code of server control .
Following code is an example, I just want to know if this can be done. I have an test.aspx file with this server side include tag;
<!--#include file="listOfCountries.htm" -->
Within listOfCountries.htm, I have:
<html>
<div>
<select id="countryList" runat="server">
<option></option>
...
</select>
</div>
</html>
Now, Is there a way to access "countryList" in test.aspx.cs file? On another note, say I didn't have the #include "Countries.htm" in test.aspx, is it possible to access the controls within Countries.htm from test.aspx.cs ? (i.e. accessing an external html file controls in cs)

Maybe this is absolutely wrong way and such things doing different way?
