Using session is trivial.
Session["Key"] = YourObject;
YourObject = (YourObject)Session["Key"]; Session will have a unique id called SessionId which will be sent along with the request to determine where to look for session data.

Keeping huge data in sessions should be avoided. Session variables are kept on server and your server will die when huge data is set on session. You can update the data to a database table and access it from the other page instead.

// Label lblId = (Label)CustomerGrid.Rows[e.RowIndex].FindControl("lblContactName");
TextBox txtName = (TextBox)CustomerGrid.Rows[e.RowIndex].FindControl("txtContactName");
TextBox CompanyName = (TextBox)CustomerGrid.Rows[e.RowIndex].FindControl("txtCompanyName");
TextBox Designation = (TextBox)CustomerGrid.Rows[e.RowIndex].FindControl("txtDesignation");
//CustomerGrid.EditIndex = -1;

string dataBaseConnection = "Data Source=DAYAKAR\\sqlexpress; Initial Catalog=hospital;Integrated Security=true";
SqlConnection updateCon = new SqlConnection(dataBaseConnection);
SqlCommand updateCommand = new SqlCommand(myQuery, updateCon);
//updateCommand.Parameters.Add(new SqlParameter("@Contactname", SqlDbType.VarChar, 50));
//updateCommand.Parameters["@Contactname"].Value = txtName.Text;
updateCommand.Parameters.AddWithValue("Contactname", txtName.Text);
updateCommand.Parameters.AddWithValue("CompanyName", CompanyName.Text);

DayaKar:
What do you meant by not able to update? Are you getting any error? Have you stepped into the code?

My site has a login page. After the user logs in he can click the logout button to logout and go back to the login page. If the user does this he can easily click the browser back button to get back into the site. How can I prevent this from happening?
|
|
|
|
|
Build your site so that it doesnt matter if they click the back button.
|
|
|
|
|
When they click the back button after logging out they can see information that is left over in the browser cache from when they were logged in. How can I prevent this from happening?
|
|
|
|
|
Set no-cache but it is still up to the given browser to determine how best to do it and they may ignore your settings.

Hi,
I have developed a web application in .net 2.0 using Word 2007, wherein I am converting a word document into a PDF file. I want to set the dcom setting in Identity tab as "Launching User" and do not want to use "Interactive User" & "This User", since client wont allow for these. I even dont want to give a Domain\Username & password in web.config file under Identity section.(Impersonation)(same reason, since Client wont allow).
When I set Identity user ( in dcom settings for word application) & access from the client machine using other username/password (other than what I have logged in on the server), I dont get any error but nothing happens even & it doesnot convert into pdf. I have also set the IIS properties for Integrated windows Authentication & unchecked the Anonymous Access checkbox.
Any solution, will be highly appreciated.
Thanks in advance

Hi,
I have a solution and in this solution are a couple of projects, and a web project. In the web project's bin folder there is a reference to one of the projects, so if the project compiles then this referenced prohect's .dll is added to the bin folder. How do I totally remove this reference? I deleted it from the bin folder, but when I compile the solution then the dll is added again.
Please can some one help.
Thanks
Brendan

No, the references are not in the bin folder.
In the Solution Explorer in Visual Studio you have a node named References in your project. That is where you can delete the reference.
Despite everything, the person most likely to be fooling you next is yourself.
|
|
|
|
|
Right Click the website take PropertyPages.There you'll find References and from that remove the project you want to delete from reference.
|
|
|
|
|
Still coming back. I have deleted several times from property pages. But after compilation it is coming back..

Hi all,
I have a page where i have a gridview with two buttons which open up two pop ups:
<asp:GridView ID="All_Orders_Grid" runat="server" AutoGenerateColumns="False" AllowSorting="True">
<Columns>
<asp:BoundField DataField="Order_no" HeaderText="Order No" SortExpression="Order_no" />
<asp:BoundField DataField="PARTY_Name" HeaderText="Party" SortExpression="PARTY_Name" />
<asp:BoundField DataField="Order_Date" DataFormatString="{0 :dd/MM/yyyy}" HeaderText="Order Date" HtmlEncode="False" SortExpression="Order_Date" />
<asp:BoundField DataField="Order_Deliv_Date" DataFormatString="{0 :dd/MM/yyyy}" HeaderText="Delivery Date" HtmlEncode="false" SortExpression="Order_Deliv_Date" />
<asp:BoundField DataField="supplier_loc" HeaderText="Supplier Location" SortExpression="supplier_loc" />
<asp:BoundField DataField="bill_loc" HeaderText="Billing Location" SortExpression="bill_loc" />
<asp:BoundField DataField="Order_Value" HeaderText="Ordered Amount" DataFormatString="{0 :#,###,###.00}" SortExpression="Order_Value" />
<asp:TemplateField HeaderText="Cash Advance">
<ItemTemplate>
#
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Option">
<ItemTemplate>
<table style="width: 100%; height: 100%">
<tr>
<td>
<a runat="server" id="lnk_Add">
<INPUT type="button" ID="Button_Add_Items" value="Add Items" /></a></td>
<td>
<a runat="server" id="Lnk_Edit">
<INPUT ID="Button_Edit_Qty" type="button" value="Edit Qty" /></a></td>
</tr>
</table>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="Order_no" HeaderText="Order No" SortExpression="Order_no" />
</Columns>
<RowStyle CssClass="datagrid_row1" />
<HeaderStyle CssClass="datagrid_heading" />
</asp:GridView>
</pre>
In the row datat bound event i wrote:
<pre>Dim btn1lnl As HtmlAnchor = CType(e.Row.FindControl("lnk_Add"), HtmlAnchor)
Dim btn1ln2 As HtmlAnchor = CType(e.Row.FindControl("Lnk_Edit"), HtmlAnchor)
btn1lnl.Attributes.Add("onclick", "return Open_Window(1,'" + e.Row.Cells(9).Text + "')")
btn1ln2.Attributes.Add("onclick", "return Open_Window(2,'" + e.Row.Cells(9).Text + "')")
the javascript i used to open the pop ups is
function Open_Window(option,orderno)
{
if(option==2)
{
var w=window.open('Edit_Order.aspx?ID='+orderno+'&&option=1')
return false;
}
else
{
var w= window.open('Add_OrderItems.aspx?ID='+orderno);
return false;
}
}
When i save the data in the child window i want to refresh the parent page which contains the Gridview. For this purpose i wrote the foll function in the code
<pre>Sub Show_Msg()
Dim scp As String = "<script type='text/javascript'>alert('Data Saved Successfully');CloseAndReload();</script>"
ClientScript.RegisterClientScriptBlock(Me.GetType(), "script1", scp)
End Sub</pre>
and the script use is :
<pre> function CloseAndReload()
{
window.close();
if (window.opener && !window.opener.closed)
{
window.opener.location.reload();
}
}</pre>
the problem i m facing is that this script works on my local host, but when i deployed it to the server, it gives me a message
"This page cannot be refreshed without resending information, Click
retry to send the information again ..."
if i click yes the pop up opens again and the user thinks the data was not saved.If i click no the page is not refreshed and again the user thinks the data was not saved.
Any solutions.......

Register the script with ScriptManager as
ScriptManager.RegisterClientScriptBlock(Me.GetType(), "script1", scp)

//HttpContext.Current.Response.Status = "301 Moved Permanently";
//HttpContext.Current.Response.AddHeader("Location", "http://digitalcolony.com");
return "Hello World";
}
[WebMethod]
public string HelloWorld()

Hi,
I'm not sure if I understand correctly, but you want to click on a button and redirect to a new website? This is what I would do:
public void MyMethod()
{
Response.Redirect("http://www.google.com/", true);
}
Let me know if I understood correctly.
Regards
Brendan
