Continues from this post[^] ~
How did you use the UpdatePanel? You should not put the whole body into the UpdatePanel.
Take a lot this link[^]
According this example, the label should be placed in UpdatePanel. If you have some more controls in that page, you shouldn't put all of them in UpdatePanel.

AJAX is just javascript. If you are talking about MS Ajax toolkit, you need to make lot of changes in web.config file. Easy way would be creating a new AJAX enabled website and copying the web.config entries to your current web.config.

Don't ask the same things over and over. The question made no sense when you first asked it, and it still doesn't. A timer is javascript, it doesn't need ajax. The page will not flicker if you use AJAX. Try sticking to one thread, and explaining yourself.

Hi all
i have a link button to add records and a dropdown list filled with data from a stored procedure and i have added "All" with index 0 at the top of the DDL.
i need a validator to prevent entering insert page unless the user chooses a value from the DDL other than "All"
i have used the following validator but not working 
<asp:DropDownList ID="ddlName" runat="server" AutoPostBack="True" Width="470px"><br />
</asp:DropDownList><br />
<asp:CompareValidator ID="nameVal" runat="server" ControlToValidate="ddlName"<br />
Display="Dynamic" ErrorMessage="Please chose a name." Operator="NotEqual" Type="Integer" ValueToCompare="0">*</asp:CompareValidator>
Any ideas!!!

What about changing 0 to "All"?

|

Didnt work too! Any other ideas.
I want the validation to alert me when i press the link button and iam choosing "All" that has index 0 from the DDL.
May be a java script will do it!!! Iam just wondering!!!
|

u should use the javascipt , there detect the dropdownlist id and find the current index , if the index is 0 then alert the user to select other then all.

I have tested. It works.. Can you try it again? Let's say there is one dropdownist and comparevalidator in your page. Set like that "ControlToValidate="DropDownList1"" and "ValueToCompare="All"" in CompareValidator.
<![CDATA[<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>]]>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:dropdownlist id="DropDownList1" runat="server" autopostback="True">
onselectedindexchanged="DropDownList1_SelectedIndexChanged">
</asp:dropdownlist>
<asp:comparevalidator id="CompareValidator1" runat="server" errormessage="CompareValidator">
ControlToValidate="DropDownList1" ValueToCompare="All"></asp:comparevalidator>
</div>
<asp:button id="Button1" runat="server" text="Button" />
</form>
</body>
</html>
Write the following code in Server-side. (Note that I used the arraylist in that sample. You can still use DDL instead of ArrayList.)
using System;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using System.Collections;
public partial class _Default : System.Web.UI.Page
{
ArrayList al = new ArrayList();
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack) {
al.Add("All");
al.Add("Michael Sync");
al.Add("Nav");
al.Add("Dave");
al.Add("Toolbox");
DropDownList1.DataSource = al;
DropDownList1.DataBind();
}
}
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e) {
}
}
Run the webproject.. Select "Nav" and click "Button". then, you will get the error as the way it should be. And select "All" and click "button". there won't be any error. I hope this is what you want.
Thanks and Regards,

Hi Everybody,
I am developing a weblproject in C# using .net2005.
In my page i have a Gridview, some text boxes, dropdown lists to enter data and a button to create a new row in the Grid.
The functionality is when user enters data in the textboxes and selects using dropdown and he has to click create button to create a new row in the Grid.
It is working fine when user clicks the create button once.
When user clicks the button multiple times (continously) then that no of data rows are creating in the gird. Here i need only one row in the Grid.
How can i overcome this problem.
Thanks in Advance

After the insert line try to use
Response.Redirect(Request.Url.PathAndQuery)
HTH

Thanks for your response.
This is not working.
Here i am not directly inserting the record into the Grid. First i am writing that record to a CSV File.From that I am constructing a datatable and giving that datatable as a datasource to the Grid.
THis is the requirement of the project.

You can prevent this by disabling the button.. If the users click the button, you can disable it by using Javascript. After the processing is done, you can re-enabled it.

Not editable. You can't edit it manually. You probably need to use the SQL statement..
