I have info from a couple of different tables that I need to be able to double click on a cell in a gridview and navigate to a couple of separate .aspx pages. Yesterday I learned how to use RowDataBound to get the name from a cell on a gridview to use in a delete confirmation dialoge box, and so am pretty sure I should be using this same RowDataBound, but I cant quite figure out where to start.
For example from the gridview below, I need to be able to double click in the "LoginIssue" field and navigate to an "EditLogin.aspx" page and subsequently be able to double click in the "ContractPath" and be able to navigate to a "ContractPath.aspx" page...or popup.

I have a user control in which I have declared a connection string as a private class variable.
I have a bunch of cascading dropdown lists in this control.
In one of my subroutines PopulateDdlPostalCodes I get an error "Connection was not initialized".
In all the other subs that use Conn, the class variable is being recognized.
If I duplicate the declaration of Conn in this sub then all works ok.
Why is this sub different than all the others?

it is said that "The Internet Explorer Web Controls is an archived ASP.NET 1.1 download".
If I have something like:
lbl1.Text = "lbl7.Text = "Blah blah text <A href="long URL">here</a>.""
Then it comes up with an error. I tried escaping the quotes but still doesn't work so what do I do?

View 1 RepliesMy project use asp.net web form, and I code it with masterpage, page and mutil webcontrol to render a web page. A problem, request it slowly. I want to increase performace. I use webservice to request data, whole web control has code to request data from webservice.
I review code, and I think if my web used webservice pooling to render a webpage. But I haven't know how to code better, remove all webcontrol, and move their code to create a web page like asp web page (not asp.net)! using only one webservice to request data...
I have a page which holds a custom webcontrol and a usercontrol. I need to reference of webcontrol in usercontrol class. So, I make the declaration of webcontrol as public in page class. But, when I do "this.Page.", I don't see the webcontrol listed in list provided by intellisense. Most probably, I am missing something.
In an asp.net page, how to get a reference of a custom webcontrol from a usercontrol?
A Template contains <input type='CheckBox'>(not server control) in my GridView.
The idea that get the which line I checked and get the data of the line at other columns.
I created this simple custom web control:

I used this control on my page:
[Code]....
The problem is that when page is displayed in web browser is see default back color, font and border, values from page are not applied on the my control. Why?
What is a Generic Class Declaration? and when should it be used?
View 2 RepliesI am working on a existing web application which I load from a folder. I mean application semms it is not created as website application from visual studio.
The controls defined in aspx are not having member declarations in .aspx.cs file and no designer.cs files were created. I mean nowhere controls are defined, but simply the controls defined in aspx are accessble in corresponding aspx.cs file wich same id of the control tag. those are being reconized even in intelligense.
How is it possible? is there any special configuration needed to make aspx controls declared automatically for aspx.cs file use.
How do I allow nullable string to my declaration?
I get this error "Type 'String' must be a value type or a type argument constrained to 'Structure' in order to be used with 'Nullable' or nullable modifier '?'." [:(]

i have a webcontrol that contains a modal popup that allows the user to enter in some information. When the user clicks submit the popup should close and the gridview on the page update. The problem that im currently getting is the page refresh is done before the data is inserted and is currently the last action fired in the life cycle. How can i make the insert within the control the first thing to happen in the page life cycle or update the page gridview once the popup has inserted the information. Im currently placing the datagrid within an update panel with updatemode set to conditional and a trigger on the custom control.

I have an XSLT transform I am using to process an XML file, inserting it into the body of my aspx page.Reference the following for background information:
background on xml/xslt
I have the following in my xml file:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

My question is: how can i create my own parameter based upon the QueryStringParameter?
Example:
[Code]....
I now called it QueryStringGuidParameter.
The purpose of this is: I'm not sending any querystring's via the aspx?querystring other thasn aspx?guid={guid identifier}.I hope my code below explains it al little bit.
[Code]....
A soon as a page Redirects f.i. with this example
[Code]....
Instead of calling Response.Redirect i call the Redirect i created. This transforms the querystring in a session with a guid and parameter. The Redirect only sends the guid in the querystring. and the receiving page picks up the guid and translates it back into a querystring.
Purpose is you have a secure way of dealing with info sending via querystrings. Lets say in the past you could easily get other info from the page by just changing a value in the key send via a querystring. In my case lets say the user request a Customer "A" with querystring ?ID=1.
Simple change the query in the addressbar to ?ID=2 (or something else) would give him another customer. Maybe a customer he is not allowed to see. (Of course this can be prevented also in the business layer, but that's not the point.)
So if i simply could create a new QueryStringParameter lets say called QueryStringGuidParameter which i can use in the ObjectDataSource but ideally just for all controllers which are able to use the QueryStringParameter , i don't have to go into code behind and set the SelectParameters in there.
I know that this topic has already discussed a lot. But, what I face today is some more strange;
My environment is, Win 7, Visual Studio 2008, ie8
I created a sample aspx and added a gridview, could make it work nicely using below style;
thead tr
{
position: relative;
top: expression(this.offsetParent.scrollTop);

If a server control was declared like this
<my:customControl id="cc1" runat="server">
</my:customControl>
is it possible to access the text between the tags?
I have what is probably a basic question but I do not understand if/why there is a difference. I have a simple asp.net page with a staticly created DropDownList and Panel control. The user can select one of three options if the drop down (Employee, Company, Address) which should load the respective custom UserControl into the panel below. By default, I have the Employee control selected in the drop down and it should be displayed on the intial Page Load (!Page.IsPostBack).
If I do the following it performs the desired behavior on the intial load:
[Code]....
If I try the following, the User Control does not appear on the initial page load:
[Code]....
I noticed if I do it with a textbox instead of a UserControl, it works however:

I assume there is some sort of behavioral difference in the way the loading is done between a UserControl and WebControl.
