{
query="select brok.*,cust.FirstName+' '+cust.LastName as Name from brokermsgrecieved as brok,custdetails as cust where brok.BrokerId='"+Session["broker"]+"' and cust.CustId=brok.FromCustId";
dt = obj.select(query);
GridView1.DataSource=dt;
GridView1.DataBind();
}
protected void Button1_Click(object sender, EventArgs e)
{
int count =GridView1.Rows.Count;
for (int i = 0; i < count; i++)
{
CheckBox chk =(CheckBox)GridView1.Rows[i].FindControl("checkbox1");
if (chk.Checked)
{
query = "delete from brokermsgrecieved where MsgId='"+id+"'";
obj.delete(query);
}
}
}

In your case the gridview is getting binded on every post back. That is why you are loosing the value. Put the code in page load under (!Page.IsPostBack).

Hi,
I have created an Master Page that resides within my root folder. I wanted to resuse this Master Page across various applications hosted in IIS. But in doing so I get the below [1] error. I googled and found following link
http://weblogs.asp.net/dwahlin/archive/2005/11/16/430779.aspx
To be more specific here is what I wanted to achieve
I have a master page @ following location
C:\Inetpub\wwwroot\Common\TemplateMaster.master
I wanted to use this master page across various applications
i.e. I wanted this master page to be used by various .aspx pages of my below applications
C:\Inetpub\wwwroot\SampleApp1\Page1.aspx
C:\Inetpub\wwwroot\SampleApp2\Page1.aspx
Following is the code for Master Page implementation within the C:\Inetpub\wwwroot\SampleApp1\Page1.aspx web page
<%@ Page Language="C#" MasterPageFile="/intranet/Common/TemplateMaster.master" CodeFile="Page1.aspx.cs" Inherits="Page1" Title="Page 1" %>
Now after the above implementation, when I try to build my SampleApp1 website, I encounter below [1] error
Is it possible to achieve this? If yes, then is there is any better way to achieve the above functionalities other than that shown in the above link?
[1]The virtual path '/intranet/Common/TemplateMaster.master' maps to another application, which is not allowed.

Hi All,
Is there any posibility to assign controltovalidate as label
for any of the validation controls
and
also i want a required field validator with label can it be possible or not?
i tried to make use of controltovalidate as label but i got an error as
control to validate is required........
Regards,
Koti

Why would you need to validate a label control? It's just there to display text (an do other events, but still). I don't think you can use the validator control to validate static controls like that(image control, label, ect.)
Can you explain a little more about why you need to validate your label?
|
|
|
|
|
why i need to validate label is
i have a calender control(ajax) and textbox(asp.net)
i was performed required field validation on textbox bec it is must and
should for me, and it allow me to edit the textbox date,
but i dont want to edit textbox..
i know the other way to keep this as readonly
finally
i dont want to show the layout of textbox so i need a label
and there must be data in label at runtime i.,e required field it is
|
|
|
|
|
So you have a textbox to edit the date value of your calender control, but you don't want to use the textbox to edit?
There's no way to use a label in they way your trying. Validation controls only work on input controls, which a label is not. Why dont you change the style of the textbox to seem like a label?

hi....
Thank you for helping me..
yah i too got the count but i am getting the count after clicking
the button submit in my page.
I wrote the code in Checkbox1_ChechedChanged.
I took the count into the label.
plz tell me where i am missing...
Thanks in advance
|
|
|
|
|
ya you miss AutoPostBack="True"
if you give AutoPostBack="True" only it will fire the Checkbox1_ChechedChanged event.
