You can developed one custom installer for that. Few years back I developed one quite similar tool. you can have a look into this
Custom Control using C# For Virtual Directory in IIS[^]
You can use this as a reference to create a custom tool.

Thanks Abhijit. But then, in my target machine the Virtual directory and Application pool are already configured and i just have to create the msi package and install it in the target machine without any wizard for getting the inputs from the user during the installation process.

Best way to deploy a site to several servers at once

I am looking for a solution that would allow us to specify where the compiled code is located at, as well as all the servers are located at and it publish it out to there with a click of a button. This solution could also compile the code if not already prior to publishing it out there, but that is optional.

I am researching now how to see if this is possible in TFS.

Any ideas?

GridView dropdownlist issue

Dear All,

I have a gridview with a dropdownlist inside a templatefield :

<asp:GridView ID="gvColumns" runat="server" AutoGenerateColumns="False" <br />
                                                                 DataKeyNames="excelkolom"><br />
                                                                 <Columns><br />
                                                                     <asp:BoundField DataField="excelkolom" HeaderText="Excel kolommen" /><br />
                                                                     <asp:TemplateField HeaderText="Database kolommen"><br />
                                                                         <ItemTemplate><br />
                                                                             <asp:DropDownList ID="ddlDbColumns" runat="server" AutoPostBack="true" <br />
                                                                                 DataSourceID="SqlDataSourceKhimportAll" DataTextField="Databasekolommen" <br />
                                                                                 DataValueField="Databasekolommen" <br />
                                                                                 OnSelectedIndexChanged="ddColumns_SelectedIndexChanged"><br />
                                                                             </asp:DropDownList><br />
                                                                         </ItemTemplate><br />
                                                                     </asp:TemplateField><br />
                                                                 </Columns><br />
                                                             </asp:GridView>

I want to get the text of the dropdownlist of the selected row:

string selection = gvColumns.Rows[gvColumns.SelectedRow.RowIndex].Cells[1].Text;

Im getting this error:
Object reference not set to an instance of an object.

How can i fix this?

Thanks in advance.

You have to use Gridview.FindControl() Method. Please do some research on it,you will able to resolve it by yourself.

You should try

String TextOfDropDownList = ((DropDownList)gvColumns.Rows[gvColumns.SelectedRow.RowIndex].FindControl("ddlDbColumns")).SelectedItem.Text

hope it helps!! Poke tongue | ;-P

sending control to another class.

I have a question in asp.net, in the page code behind when filling a gridview with data for example, i send a reference of the gridview to a controller class to fill it with data to avoid writing a lot of code in the page's code behind for example i write in the page load the following:
Controller.GetData(DataGridView);

does this mean i'm sending too much data from the client to the server? Is there a difference in performance between this and between filling the data in the page's code behind? in my opinion there's no difference, as this code already runs on the server and controls are created on the server, so no effect on the amount of data transferred from client to server. any ideas?

What are you talking about ? ?? Confused | :confused:

Is it a web service where you are sending the DataGridView ?

If it is just a class, then the object is already loaded in memory. You can process the memory wherever you want.

Hi,
No, it's not a web service, it's a regular web application, i'm newly working in web applications and some collegues argued with me about this,claiming that this will increase the load on the server and lower the performance beside that it's not correct to send controls between presentation and bussines layers, but i thought if i send a reference of all controls (in an arraylist) in my page to the bussines layer and filling the data goes there, i would minimize code written in the page to bind all controls, but actually i didn't see any one doing this before, so i'm not sure if this was a good idea.

Well, Actually there is no difference. The only thing is that, we always try to separate the presentation layer with data.

It is just because of the separation of code. Say you have implemented 2 or more layers. Your intension is just to separate the Layers so that they could be reusable.

If you send the control, the data layer will be totally dependent on the presentation layer, and thus if this is what you do, then it will be better to have all the data layer classes in the App_Code of your project.

Actually, we all start creating Layers for separation of code, but gradually it becomes so much dependent that we cant plugin the other layer if the presentation layer is changed.

I think if you like to reduce the code, try creating a new Class in your APP_Code and place those code there. From Data layer, you call only for data and manipulation of controls could be made in your application layer.

By this, I definitely mean that there will be no difference if you send though. But at least this is not a good idea... Wink | ;)

If you want to read on how to Refactor code, and reduce Dependency between layers, you might have a look into one of my article :
Simplify Code Using NDepend[^]

I think it will give you the idea on what I am talking about.

Cheers.

Is this is your work assignment ? What have you tried till now ? Please don't come up with any abstract question. This is not an easy task. You need some web services which will communicate with mobile to update the info. You need to contact with mobile connection provider.

If your client is the Service provider, just create the web interface and after payment is made, you update the value of the database.

If you a 3rd party, there should be some service available to the service provider which could update the value after recharge is made.

I dont know what is the problem you are having.
