Not very clear what you are trying to do and why it has gone wrong. There are plenty of examples of using check boxes in grids - you need to do a porper search on Google. You talk about an auto-increment column: what do you mean by this?

ok i will ....auto increment coloumn means only one row cell(auto inc col) will be check at a time ......like group radio button works 
|
|
|
|
|
Well it looks like from your post that you know you need to supply code for this. Have you written any code to uncheck the other boxes?
If so, it would be benifical to see it to help further. Also let us know if you are getting any type of error messages, or what exactly is happening when you click the auto inc column.

there is a checkbox outside the gridview for checking the inside col cell of gridview and if i chk inside gridview col cell then it checks outside the gridview as it happens in mysql query browser .....thnx in advance
<pre lang="c#"> private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
try
{
q = (string)dataGridView1.CurrentRow.Cells[0].Value;
if (q != null)
{
cntextbox.Text = (string)dataGridView1.CurrentRow.Cells[0].Value;
dttextbox.Text = (string)dataGridView1.CurrentRow.Cells[1].Value;
if (Convert.ToBoolean(dataGridView1.CurrentRow.Cells[4].Value) == true)
checkBox1.Checked = true;
else
checkBox1.Checked = false;
if (Convert.ToBoolean(dataGridView1.CurrentRow.Cells[2].Value) == true)
checkBox2.Checked = true;
else
checkBox2.Checked = false;
if (Convert.ToBoolean(dataGridView1.CurrentRow.Cells[3].Value) == true)
{
foreach (DataGridViewRow dr in dataGridView1.Rows)
{
dr.Cells[3].Value = false;
}
checkBox3.Checked = true;
}
else
checkBox3.Checked = false;
}
}
catch (Exception)
{
}
}
private void checkBox1_CheckedChanged(object sender, EventArgs e)
{
if (checkBox1.Checked)
dataGridView1.CurrentRow.Cells[4].Value = true;
else
dataGridView1.CurrentRow.Cells[4].Value = false;
}
private void checkBox2_CheckedChanged(object sender, EventArgs e)
{
if (checkBox2.Checked)
dataGridView1.CurrentRow.Cells[2].Value = true;
else
dataGridView1.CurrentRow.Cells[2].Value = false;
}
private void dttextbox_TextChanged(object sender, EventArgs e)
{
dataGridView1.CurrentRow.Cells[1].Value = dttextbox.Text;
}
private void cntextbox_TextChanged(object sender, EventArgs e)
{
dataGridView1.CurrentRow.Cells[0].Value = cntextbox.Text;
}
private void checkBox3_CheckedChanged(object sender, EventArgs e)
{
if (checkBox3.Checked)
{
foreach (DataGridViewRow dr in dataGridView1.Rows)
{
dr.Cells[3].Value = false;
}
dataGridView1.CurrentRow.Cells[3].Value = true;
}
else
dataGridView1.CurrentRow.Cells[3].Value = false;
}
here checkbox3 is used for auto inc that is causing the problem

Hi,
You can't do that using Asp.net web project alone, you either need to use Flash Action script or SilverLight with asp.net.
Flash: You need Flash multimedia server also known as FMS for setting up audio video communication between client and server.
SilverLight: You need to develop or your own service as a server application to setup communication between client and server.

Hi,
I am opening a jquery dialog on button click.I am opening panel as dialog.
In that panel there is iframe and in that iframe src I have called the new page.
Popup is opening properly at the first time.
I am closing the popup and by clicking on button to open the popup again.
When I am opening the popup 2nd time I am facing 2 problems
1. If I click on the button 1st time popup is not opening. If I again click the button 2nd time then popup opens. Popup is opening on 2nd click but not on 1st click. I am not able to find out why the popup is not opening on single click and opening on double click.
2. I have TextBox control in popup. When I open popup 2nd time in IE this TextBox control is in disabled state. If I fire any server side event in that page like button click then that TextBox control gets enabled. While in Mozilla Firefox it is working properly. That TextBox control is always in enabled state.
Please let me know how can I solve this problems.
My jquery function is as follows
function OpenPopupTest()
{
$("#PanelTest").dialog(
{
minWidth: 500,
minHeight: 500
});
}
I am calling the following panel
<asp:Panel ID="PanelTest" runat="server" Style="display: none; background-color: White;
font-size: 12px;">
<div id="DivTst" style="text-align: left; margin-top: 20px; margin-left: 10px">
<iframe id="iframeTest" src="Test1.aspx" height="400px" width="400px"></iframe>
<br />
</div>
</asp:Panel>
<button ID="ButtonTest" runat="server" Value="Open Popup" />
This button is inside update panel.
In code behind on botton attribute I am calling the javascript function.
ButtonTest.Attributes.Add("onclick","OpenPopupTest()");
Any help would be greatly appreciated.
Thanks in Advance.
Regards,
Rahul Rathi

Can you let me know in what event are you using the below code?
ButtonTest.Attributes.Add("onclick","OpenPopupTest()");
You have to add the attribute to the button in an event before the button is clicked. For Ex: PageLoad event.
If suppose you have placed the code in the button click event, the attributes will not be added until the button is clicked for the first time. So when you click the second time the popup will be displayed.

Have you tried
$("#PanelTest").show();

Is there a method in .net for (without actually executing it) like Query Analyzer does?
|
|
|
|
|
Create a script to run your query inside a transaction and then rollback the transaction. Execute this script from .Net using ADO. An exception would generally indicate a problem with the query. Note that this method might be expensive depending on what your query is.

I have developed a subscription based web application using ASP.NET (C#). Applicaiton is used to give user accounts to different customers to download some files from website. I want to measure the bandwidth used by each customer account during downloading. I'm using SQL Server 2008 at the backend where the user account information as well as download history and total download size are maintained on it.
Infact I want to calculate the bandwidth used by each customer during any download file process. Each customer is assigned certain amount of bandwidth. I want to calculate this during the session of a customer, not at the website level.
Something exactly like "sharing-hub.com" website.
Any comments and suggestions are welcomed.

Bandwidth is downloaded amount of data divided by the time need to do so. You only need to additionally record download start and download end time.

I need to retrieve the download size during downloading a file.

Hi,
You need to use handler to process file download request.
When client request the file download, file handler will search the file and calculate it's size. You can store the file size downloaded against the user and restrict user from further downloading if allowed quota reached for the day or week etc..
File handler

hi
what is best practice for showing single record from DataSource controls (SqlDataSource, AccessDataSource, ...)
this is quite common situation; lets say i need to show simple data from database based on id that is passed via querystring
using repeater for only one record feels wrong?
<asp:Repeater runat="server" ID="rpt" DataSourceID="sds">
<ItemTemplate>
<%#Eval("Name") %>
<br />
<div>
<%#Eval("HTML") %>
</div>
<ItemTemplate>
</asp:Repeater>
<%=DetailHTML() %>
<asp:SqlDataSource runat="server" ID="sds" SelectCommand="select * from MyTable where id=?">
<SelectParameters>
<asp:QueryStringParameter QueryStringField="id" DefaultValue="1" />
</SelectParameters>
</asp:SqlDataSource>

I would be inclined to create a suitable control on the form and then populate it from code behind. That way you can render the control with any styles, etc, ready to accept the value. Perhaps like:
<asp:Label ID="Label1" runat="server" CssClass="bold fancyfont veryverybigsize" />
In the OnLoad event (or wherever you deem appropriate):
if (!IsPostBack)
{
result = GetStringValueFromDatabase(Parameter);
Label1.Text = result;
}
or similar.,

It really is up to you. You can use a grid view, a datalist, textboxes, labels, etc. It all depends.

ye, i know... i need to develop master page for portal that has content like this:
////////////////////////////
//div
//
//Check our latest product!
////////////////////////////
////////////////////////////
//div
//
//Pool: What do you think?
//1.
//2.
//3.
////////////////////////////
////////////////////////////
//div
//
//TOP 1 video
////////////////////////////
////////////////////////////
//div
//
//Latest client activites
////////////////////////////
...many more
so i have plenty of "single record" DataSources (queries like "select something from myTable where id=1")
the way i did this is:
////////////////////////////
//div
//
//<asp:repeater datasourceid="productSds">
////////////////////////////
////////////////////////////
//div
//
//<asp:repeater datasourceid="poolSds">
////////////////////////////
////////////////////////////
//div
//
//<asp:repeater datasourceid="videoSds">
////////////////////////////
////////////////////////////
//div
//
//<asp:repeater datasourceid="activitiesSds">
////////////////////////////
but using x repeaters for x "single record" DataSoruces feels wrong. so i am just wondering is this approach ok?

It isn't wrong because it allows for future flexibility but you may want to create a user control for each of those items and just use labels and textboxes or whatever you want in the control. Then just add as many of the usercontrols onto your page. That may make management of it easier.
