I have always been banging my head for this:
Why <a runat="server" onclick="CodeBehindFunction()"> does not work (in simple html without databound controls) even if we make it to run at server?
(I know we can always replace such anchor requirement with asp:LinkButton as it ultimately get rendered as anchor in html.)

I have three TabPanels depending on which tab is clicked I would like to call a different c# function to display different content. I know I could just run all the functions when the page loads but this seems messy. I'm sure there is a way to do this but I'm not having much look. It's possible I'm thinking about this from totally the wrong angle so please let me know if you can think of a better way to do this.
Example ASP.net
<ajaxToolkit:TabContainer ID="tabParameters" AutoPostBack="true" Width="100%" runat="server" ActiveTabIndex="0">
<ajaxToolkit:TabPanel ID="tabDetails" OnClientClick="Load_Details()" HeaderText="Details" runat="server">

var Panel = $find("<%=RadPanelBar2.ClientID %>");
//To find the Tab Strip
var tabStrip = Panel._findItemByValue("QueueGridPanel").findControl("RadTabStrip2")
tabStrip.get_tabs().clear();
var newTabNames = "MyTab1,MyTab2,MyTab3";
//var newTabNames = document.getElementById("ctl00_GridContentPlaceHolder_hfTabs").value;
var TabsNames = newTabNames.split(',');
var i = 0;
while (i < TabsNames.length) {
var ntab = new Telerik.Web.UI.RadTab();
tabStrip.get_tabs().add(ntab);
ntab.set_text(TabsNames[i]);
i++;
}
return false;
}
I am trying to build a site that will display a word ("Synset" in my code) from a "function call", (ultimately the word will come from another database but I'm ignoring that part for now). The user will click one of 4 radio buttons deciding if the word is "positive", "negative", "neutral", or "can not be determined". Then the user clicks "Save" the word is saved a MS SQL database, the function is called displaying a new word and the process is repeated.
So far I have been able to get this to mostly work by using the code below. The problem is that the function is called and the correct word displayed when the page loads the first time, when I click a radio button and then the "Submit" button, the word and value from the radio button are saved to the database but then no new word is displayed. The text just disappears. The new word is created, as I can see that new words are saved to the database when i click submit.
I'm thinking the issue might be because I'm binding the text attribute of the label I'm using to display the word to the sqldatasource, because it's probably trying to display the text from the database?
I've tried putting the code that gets and displays the new word in FormView1_PageIndexChanging() and submitButton_Click() and neither work.
I've tried to just call Response.Redirect("Default.aspx") in submitButton_Click() and this displays the word but nothing is saved to the database.

My motto is to call a Java script function at the end of button click code behind. ie, firstly i need to execute the server side function after which my java script function should get invoked. My server side method is as follows
protected string SaveEmbedURL_click()
{
if (txtembedurl.Text != null)
{
School aschool = new School();
aschool.SchoolId = CurrentSchool.SchoolId;
aschool.EmbedUrl = txtembedurl.Text;
SchoolRespository.updateEmbedUrl(aschool);
return "true";
}
}
My Java script function is as follows
function SaveEmbedUrlClientSide() {
admin_CustomizeTheme.SaveEmbedURL_click(true);
$('#lbl_embedcode').removeClass('hide').addClass('show');
$('#embedCode').removeClass('hide').addClass('show');
CopyToClipboard("embedCode");
}
I am trying to call a web service function within my own ASP.net (code behind) using AJAX on the page.
Once i push the button to execute the JS/AJAX/codebehind - I got an error.
POST http://************/admin/Admin.aspx/getDBInformation 500 (Internal Server Error)
This is my code below that I am currently using:
Code:
<WebMethod> _
Public Shared Function getDBInformation() As String
loadDBData()
Return JsonConvert.SerializeObject(dbInfo, System.Xml.Formatting.Indented)
End Function
End Class
The code behind looks like this:
Code:
Imports System.DirectoryServices
Imports System.Security.Principal
Imports System.Net
Imports System.Drawing
Imports System.IO
Imports System.Data.SqlClient
Imports System.Web.Services
Imports Newtonsoft.Json
[Code] ......
How can I correct this issue so that I am able to call **loadDBData()** without that 500 error?
I have several web sequential pages which will modify a record and its child records in the database, called a "project". Such a project is currently passed between pages using its database ID in the URL parameters.
A project has some information specific to itself, and also consists of one or more Tasks, which each have information specific to itself.
Is it faster (alternatively, more maintainable or more easily understood) to hit the database each time I need to query the same project (and its tasks), or should I query the database once (either once for each page or once for all pages and save to Session) and check the saved object rather than the database?
