Hi,
Please specify what problems you are facing ? By the way you have to start query string with a '?' marks and between two parameters you have to put a '&'. Also there is no need to put the param values in single or double quotes !
If you can specify some details, it would be easier for all here to understand actuall situation !

Hi,
If it is a Web Application then i dont think that it is possible in pure ASP.NET. You will have to use java script for that.

You may have a look at the oncontextmenu[^] event to see how to use it to open a pop-up window with the right click action.

It's simple, the method is used to add the headers to the Response object which is later sent back to the client. I think the topic you may want to learn more is the header part of a Http message, check out this rfc[^]

Is it possible to open a popup window on right click on a row of a datagrid at
client side?

Yes, it is. You can look at the oncontextmenu[^] event, and lots of datagrid examples from this girl[^]

In C#, .NET 2.0. I have a gridview in frm_Report which looks like this.
i have used the sqldatasource to bind the data.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="Stud_Admin" DataSourceID="SqlDataSource1">
<Columns>
<asp:BoundField DataField="Stud_Admin" HeaderText="Stud_Admin" ReadOnly="True" SortExpression="Stud_Admin" />
<asp:BoundField DataField="Stud_Name" HeaderText="Stud_Name" SortExpression="Stud_Name" />
<asp:HyperLinkField HeaderText="" Text="View" DataNavigateUrlFields="Stud_Admin" DataNavigateUrlFormatString="frm_StudReport.aspx />
</Columns>
</asp:GridView>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:FYPJ_TestDBConnectionString2 %>"
SelectCommand="SELECT [SN], [Stud_Admin] FROM [Stud_Particulars]">
</asp:SqlDataSource>
In my another form frm_Show is basically this.
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
When user select the hyperlink View, the hyperlink will grab value of Stud_Admin of the selected row in gridview and display it at Label1. What is the next code should I add?
thanks in advance. Much appreciated.

use Row.RowIndex property to get the selected row..
use RowCommand event of GridView.

I don't know what to do next. By getting the values, how will the hyperlink be clever to pass value to label in another form. And what is the syntax for Label1.text = ? By using findcontrol?
And
protected void GridView8_RowCommand(object sender, GridViewCommandEventArgs e)<br />
{<br />
GridViewRow row = GridView8.Rows[0];<br />
}
thanks in advance. Much appreciated.

If the Stud_Admin text is simple, you may consider passing the value along with the url in the query string (set this DataNavigateUrlFormatString="frm_StudReport.aspx?Stud_Admin={0}" )so that you can get it from the Request object in the next page . In addition, you still have many other choices:
+ Try to retrieve again in DB based on the id passed from the source page when the text is long.
+ Try to use the LinkButton, so before redirecting to the next page you can save the text in the Session.

 Thank you. It works.

But I was just wondering what does Stud_Admin={0} means?
If I want to pass two values which is Stud_admin and the next column just next to Stud_Admin? What will the longer DataNavigateUrlFormatString = be?
thanks in advance. Much appreciated.

I still don't understand.
I am using codebehind. And initially i can fetch one data from the gridview to another webform and display it in the label.
I want to experiment and fetch two datas from the gridview to another webform and display it in the label.
<Columns>
<asp:BoundField DataField="Stud_Admin" HeaderText="Admin No" ReadOnly="True" SortExpression="Stud_Admin" />
<asp:BoundField DataField="Stud_Name" HeaderText="Student Name" SortExpression="Stud_Name" />
<asp:HyperLinkField Text="View" DataNavigateUrlFields="Stud_Admin" DataNavigateUrlFormatString="frm_StudReport.aspx?Stud_Admin={0}"/>
</Columns>
And another webform at the page load,
<code>Label1.Text = Request.QueryString["Stud_Admin"];</code>
How can I fetch the Stud_Name as well and display it in Label2.text?
thanks in advance. Much appreciated.

Well, the explanation in MSDN is clear enough:
+DataNavigateUrlFields="Stud_Admin,Stud_Name" (seperated by comma)
+DataNavigateUrlFormatString="frm_StudReport.aspx?Stud_Admin={0}&Stud_Name={0}" (the parameters in the url are seperated by the &)

Thanks many-many.
minhpc_bk wrote: +DataNavigateUrlFormatString="frm_StudReport.aspx?Stud_Admin={0}&Stud_Name={0}" (the parameters in the url are seperated by the &)
Though this should be right,
DataNavigateUrlFormatString="frm_StudReport.aspx?Stud_Admin={0}&Stud_Name={1}"
thanks in advance. Much appreciated.

Help!
I need to force a postback...
The reason why is, I am using a Menu, and I have configured the StaticSelectedStyle for it, and it works fine, until I set a NavigateURL for the menu items! According to a Microsoft article, when there is a NavigateURL set, and the menuitem is clicked, it navigates to the new page, and does not perform a postback... so the StaticSelectedStyle does not get called, and my menu does not get updated...
Here's the article I'm referring to:
http://msdn2.microsoft.com/en-us/library/system.web.ui.webcontrols.menuitem.aspx
Here's the info from the Microsoft article:
When the user clicks a menu item, the Menu control can either navigate to a linked Web page or simply post back to the server. If the NavigateUrl property of a menu item is set, the Menu control navigates to the linked page...
Thanks so much for your help!

try with ...
if(Page.IsPostBack)
{
//set of code to be executed during Postback
}

Jay

Hi,

Its simple. Dont set the NavigateURL. Then according to the above info, it will post back. Here you call whatever functions u want to and then use Response.Redirect("URL")
You can try it (atleast)

Because it navigates to a new page so the menu control does not remember the current selected item, in this case you simply check the current url then set the selected menu item accordingly.
