I'm working in vb .net, for a web application. I'm trying to do this:
txtbox_GroupCustom2.Text = grdlst_customtemp.Item(1, 0).Value
I got this code from a working windows version of the software, now I'm rewriting the code of the windows to make it web based. How can I access the values of the gridview?
I have a Data Bound DropDownList and a Panel in a step of the CreateUserWizard. I would like to make the panel visible based on the selected value of the DropDownList.
Here is my code that is not working. Any help identifying what I missed is appreciated. (Yes Post Back is enabled on the DropDownList.

I'm trying to convert a windows based application to a web based using vb.net.
I am having a problem with the following:
System.Windows.Forms.WebBrowser
is there any similar web calling to this?
I'm doing this:
Dim htmlbox As System.Windows.Forms.WebBrowser
But obviously im unable to do this since it's a windows.. I need to find something similar for web.
I have a bound datagridview with the associated tableadapter, dataset and bindingsource. A different component in our application can add or delete rows displayed by the datagridview. When this happens, the underlying database edits are correct. The problem is that the datagridview seems to lose track of the data.
Currently, when we receive the event that our data has changed we do the following.
this.DataSet.Offers.Clear();
this.TableAdapter.Fill(this.DataSet.Offers);
this.BindingSource.ResetBindings(false);
this.DataGridView.Refresh();
If our example had something like 5 items displayed in the grid and a row was deleted, the grid refreshes with 3 items shown. If we manually refresh our grid through a button calling the exact same code, it displays the correct results. Is this an asynchronous call? Should we be refreshing the grid in a different area?
I wanted to ask about URL rewriting. I want to map this: [URL]
To: [URL] Being DVD players product id 123.
Also I will like to map sub domains like this:
From: [URL]
To: [URL]
Being John Doe user id 123. I will like to do this by getting the respective ID (for products and users) from a database based on product id name (dvdplayers) and sub domain name (johndoe). Where can I intercept these 2 (sub domain string and product name string) and based on this getting the info from DB and "rewrite" the URL's?
I want to make a button in footer template invisible from code behind, but i am unable to do that.
I tried
[Code]....
GridViewDetails uses templatefields. In edittemplate I put a button called "ButtonUpdateAdjustAmount" with OnClick="Update_AdjustAmount" in the EditItemTemplate for the "Amt to be Adj" column. There is also a textbox. My user's should be able to edit the textbox, but I also want the ability to click the button and the textbox populated with the correct calculated value. The formula varies based on the "code" column which is a dropdownlist called "DropListCode".
I am fairly new to asp.net, vb, etc...so forgive my code writing. Eventually I need to also put the same functionality on the insertrow for my gridview. But first wanted to get the edit one working. I am using templatefields for all columns and the FooterTemplate to perform the Insert New Detail Line.
I can get the functionality to work for the first data row and only if I take out the If code.SelectedValue = ... line and leave 1 static formula. However that isn't going to work. If DropListCode.SelectedValue is DNR then AdjAmt should be ((q_ordered - q_received) * cost). If DropListCode. SelectedValue is OV then AdjAmt should be (RKNumber * cost). If DropListCode.SelectedValue is NB the AdjAmt should be ((q_received - q_ordered) * cost). If DropListCode.SelectedValue is DAM then AdjAmt should be (RKNumber * cost)

I'm going to be deploying an app in the near future on an IIS7 server, and would like to use the per-application URL rewriting settings in web.config, but this is not an ASP.NET application, so I have no need for anything superfluous.
What is the absolute minimum I need in my web.config in order to run my application and use URL Rewriting?
I am trying to implement URL rewriting technique in my Web application.I have found some articles on net 2 rewrite URL. But i m not able to understand. tell me any API or DLL which will take care of all url rewriting techniques in my Web applications.
I have heard something abt UrlRewriter.ddl . But i have not used it yet. provide me the easiest way to do that. If any sample application is there then it will be better ti understand
I'm working to move my simple asp.net website to a three layer architecture. Currently I have Linq queries like the one below in my code-behind files. Basically this code snippet retrieves a collection of customer data from the database and then binds it to a grid control.
I'm wondering if someone can guide me on how to rewrite this in order to move it to my newly-created data access layer. I'm thinking I will turn it into a class (e.g. GetUserBoxesByStatus()) that can be reused throughout the site.
var boxes = from p in sbm.Packages
where p.UserID == CurrentUserId && p.StatusID > 1 && p.StatusID < 3
select new { p.PackageTag, p.PackageName, p.DateReceived, p.DateShipped }; [code]....
Some of the options that I've investigated but have not had success implementing are the following:
DataTable --- returning a DataTable seems like the best solution but it also appears to require a lot of potentially unecessarry code to define a table (isn't the data source already mapped in my Linq 2 Entities dbml?)
IEneuerable --- I think I could pass an IEnumerable list between the layers but after reading many tutorials about Linq I'm still a little lost DTO --- Conceptually I think I understand what a DTO is but I am not clear on how to begin implementing this approach POCO --- Again, the concept seems logical enough but I don't know how to put this into practice
how they would tackle this using one of the above or some other solution.
When writing inline code in an .aspx file and some lines down closing a statement with <% } %>, Visual Studio tries to be nice but messes it up by rewriting it all. Is there any way of turning this rewriting off, but only for inline code?

I have a text box and some validation on it. I want to make a panel visible only when
it is successfully validated,i.e.,textbox entry is valid.Also,I want to capture the entered valid value(it should be integer within 1-8) in a session,based on this number,I am going to add that many rows in an editable grid view.
I have a WCF 3.5 service with JSON and a aspx page consuming it by using ASP.NET Ajax Library

I even restarted the machine no change, looked up on the internet, msdn and I have Default pool with Integration mode

I have atleast 10 websites that have different css,html,javasacripts and webconfig. But the same code behind files.With this design everything is hard to maintain. So I decided to work on it and I started moving all the queries in the code beghind file to stored procedures. Since every website uses the same database.
What I have decided is to make use of themes and multiple master pages? IS this the best way to go about it?
Also lets say I have two templates. There is site A and site B. both using different templates. And have pages Home About Us and Contact.
Now would I be creating three different masterpages? for each template so 6 in total? ( since none of the templates are supposed to look the same)
or Should I just create two masterpages? if so how would I manage the html of the page so it looks different?
I have created a custom control that implements Templates (based on Panel controls) ... I can do a FindControl to locate imbedded controls. This allows me to get and set values in the imbedded controls, but I want to be able to reference the imbedded controls like they are properties of the associated panel. Here is a sample of how my custom control now works:
<cc:CustomControl ID="myCustomControl" runat="server">
<PanelTemplate>
<asp:TextBox ID="myTextBox" runat="server"></asp:TextBox>
</PanelTemplate>
</cc:CustomControl>
I can do the following (where my custom control has given the panel hosting the template the name "myPanel"):
Dim txt As TextBox = myCustomControl.myPanel.FindControl("myTextBox")
txt.Text = "Some text to put in TextBox"
What I want to do is:
myCustomControl.myPanel.myTextBox.Text = "Some text to put in TextBox"
Im getting error after i rewrite my url,earlier my code was woking fine but as i rewrite my url im getting error.
The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
In App_code i have used class file consists--
public class FormRewriterControlAdapter : ControlAdapter

I have a page where you can search and display other data, very simple layout. 1 Gridview and 1 objectdatasource. But i have 4 possible buttons that can populate the gridview..
i would like to control my objectdatasource from the code behind based on the button you click.
here is what i have right now.. but if possible, can this source not be hardcoded like this and only built in the code behind?

I found this site with a solution to this persons issue, but i cant seem to get mine working this way.

I have an application where I make advanced engineering/science calculations.
The application consists of 25 equal calculation "lines" which I have made as user controls:
web form:
Code:
[code]....
However the performance is quite bad because each line load from a database. Each line becomes visible when the last line has been clicked so I only need in fact 2 lines to be loaded at the beginning.
Can I make a smart code where the next user controls loads instead of the HTML that I have made, where all 25 lines appears and loads but are not visible until the line before has been used?

I am tasked with providing a membership form that requires users to given their postal addresses. The form needs to be very friendly to maximize data accuracy. So I am required to take the user's country and their zip code and from that pre-populate the town field. Moreover, this must be done in the official language of the country chosen e.g.Japan/Japanese. Since I don't really believe this is yet
possible, my starting point will be an English version of this.
Does anyone know of a database/web service that can provide*international* address information based on country and zip/postal code?
