Try this one in form tag
<form id="form1" enctype="multipart/form-data" method="post" runat="server">
i am trying to fill text box from database on dropdownlist selected index changed without page post back.
i tried the following code it does not work
<script runat="server">
private String queryString;

{
if (!String.IsNullOrEmpty(queryString))
{
Class1 obj = new Class1();

}
}
}
protected void Page_Init(object sender, EventArgs e)
{
queryString = "?foo=bar;a=b";

</script>
Look into ASP.NET PageMethods. Here's a sample:
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true"></asp:ScriptManager>
<asp:DropDownList ID="ddlEmployee" runat="server">
<asp:ListItem Selected="True" Value="1">One</asp:ListItem>
<asp:ListItem Value="2">Two</asp:ListItem>
<asp:ListItem Value="3">Three</asp:ListItem>
<asp:ListItem Value="4">Four</asp:ListItem>
<asp:ListItem Value="5">Five</asp:ListItem>
</asp:DropDownList>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</form>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
<script type="text/javascript">
$(function () {
$("#ddlEmployee").on("change", function () {
PageMethods.SetText($(this).val(), OnSetCompleted);
});
function OnSetCompleted(result) {
$("#TextBox1").val(result);
}
</script>
In the code-behind:
[System.Web.Services.WebMethod()]
[System.Web.Script.Services.ScriptMethod()]
public static string SetText(string id)
{
//do your DB stuff here
return "You selected " + id;
}

I have a div in default.aspx with img inside as follow
<div id="sTab" class="tabs firsttab" runat="server">
<asp:Image ID="sTabImg" src="images/home.png" runat="server" />
Activities
</div>
I want to perform some action on click of the div in ASP.NET (not in javascript).
I tried the following
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
}
sTabImg.Attributes["onclick"] = ClientScript.GetPostBackEventReference(this, "ClickDiv");
}
protected void ClickDiv()
{
Label2.Text = "helo got it";
}
The page is getting refreshed and when i debugged the issue, its not entering the ClickDiv function..What wrong here..
From Here
public partial class _Default : System.Web.UI.Page, IPostBackEventHandler
{
protected void Page_Load(object sender, EventArgs e)
{
div1.Attributes["onclick"]=ClientScript.GetPostBackEventReference(this,"ClickDiv");
}
protected void Div1_Click()
{
// Do something
}
#region IPostBackEventHandler Members
public void RaisePostBackEvent(string eventArgument)
{
if (!string.IsNullOrEmpty(eventArgument))
{
if (eventArgument == "ClickDiv")
{
Div1_Click();
}
}
}
#endregion
}
You have to implement the IPostBackEventHandler Interface.
Why not use ImageButton?

{
Label1.Text = "You clicked the ImageButton control at the coordinates: (" +
e.X.ToString() + ", " + e.Y.ToString() + ")";
}
</script>

I want to update the text property of my textbox control in Asp.Net from within loop.I have tried using Ajax updatepanel with the timer control but unable to update the text property.I have been searching this since last week but unable to find any answer any help would be higly appreciated
Following is the detail:
This is my button click event in this code you can see I am updating the
TxtContent.Text
within a loop the text is being returned by a user defined function called
ReturnBodyText()
afterwards I am assigning the text to the viewstate so that at the timer tick event I can recall the text and update the textbox text property and then at the timer tick event assigning the viewstate values to the textbox.
protected void Button4_Click(object sender, EventArgs e)
{
ArrayList FilePath = (ArrayList)ViewState["ArrayList"];
int i = 0;
int b = 1;
foreach(string[] sr in FilePath)
{
string Month = sr[i];
string datewithzero;
datewithzero = String.Format("{0:00}", b);
string[] FilesArray = (string[])listfiles(Month, datewithzero).ToArray(typeof(string));
foreach (string FileNameWithExtension in FilesArray)
{
ListBox4.Items.Add(FileNameWithExtension);
TxtContent.Text = ReturnBodyText(Month, datewithzero, FileNameWithExtension);
ViewState["Content"] = TxtContent.Text;
Timer1.Enabled = true;
Timer1_Tick(ViewState["Content"], e);
}
i = i + 1;
b = b + 1;
}
}
protected void Timer1_Tick(object sender, EventArgs e)
{
TxtContent.Text =(string) ViewState["Content"];
TxtContent.DataBind();
}
I Hope the above description will help you guys in understanding my problem

Sadly, your code did not help me much. However, I wrote this which I believe does what you want -partially-. It seems to me nothing more can be done though. Here is the code:
