I have a Grid view which is being populated from a database. Now I want to add a button that has its own html with some Hidden fields. I have introduced an Template Field and put the html in that field which works fine. But now I want to send the values in hidden field dynamically. i.e. the Id and value comming form the database.

I have a gridview that is populating from a SQL DB and working fine. However, based upon certain data I find in fields in the SQL table, I want to place a 'n' or a 'y' in extra columns in the gridview that I am assuming need to be templatefields. My thought was I could maybe add 8 template columns and then I could put a 'y' in the appropriate column based upon the data I find the table. For the life of me, I cannot figure out how to do this. I want to do this at rowdatabound time ( i think) but I just cannot find out how to, in my code, put that 'y' in the columns. Is this the right way to do this or do I need to do it another way? How do I get that 'y' in the proper column?
View 3 RepliesWhat is the best way to do the above? Basically i have a drop down list box with a list of names pulled from a database. When someone selects a name i would then like to populate two further boxes with the persons Login ID and Email address which are held on the same DB. I have currently been using Combox1_selected index change and then running a select query on the database to fill in the other fields - unfortuntly this is too slow. There must be a better way then this? I will also need to put the values in a DB in a later stage so will need to be able to retrieve these values.
As an infopath developer this can be done easily on InfoPath using a filter - is there anything similar in ASP.net
I'm not sure if I can explain this properly, I just need some advise. I'm working with a formview and datasets to populate the information. However I have a table specifiying which fields to display. In my table If cell, work and home fields are selected then those fields must be populated in the formview if they not selected then it shouldn't be shown. These are 2 different datasets being pulled into the formview.
Right now I have a datasource populating the formview via the wizard, not sure what to do next.
I have a web form that has 2 hidden fields , Formname & CreateDate ( essentialy a timestamp).

I'm currently building my website and have hit a brick wall. I've not begun coding anything fro this yet as I am unable to get my head around it and not sure where to start.
I've got a database table with a list of town/ county names ( columns are id, town, county).
What I'd like to do is have a template page with set places for town/ county names and then when a particular area is searched for in google/ bing etc my template page with the relevant town/ county name is shown.
I know that's a bit vague so if you have any questions, let me know. One thing I don't want to do is manually create a page for each individual town/ county!
I have scenario, where there are html hidden fields, the page can be redirected to itself, with parameters, I have sessions too. Now depending on session value I want to set some hidden values, so that it can be picked up from javascript and can do certain operation. But, the problem is I have no idea about how to get/ set values into html controls using asp.net, and also do not know whether this is possible or not. it is imperative that I need some way to hold some data that can be set using asp.net and can be picked up by javascript. Since session can not be used for this purpose, so I need some other way.
View 2 RepliesI've been using .NET for a little while now. And, I now want to learn to use it the RIGHT way. And, by that, I mean I shouldn't be using hiddenfields on my .aspx page and setting values for those hidden fields in my codebehind. Problem is, I don't know how to ask the question.. so bare with me.. getting a value from a gridview, detailsview, or in this case a DataList when it's bound on a .aspx page, and passing it into my stored procedure? Here's my code of how I do it now..
here's the label for the Department from my datalist, which is on my .aspx page
<asp:Label ID="lblFullDept" runat="server" Text='<%# Eval("FullDept") %>' />
here's the hidden field from my .aspx page
<asp:HiddenField ID="hdnFullDept" runat="server" />
And now for my code behind - where I find the value during the databound of the datalist, and then set the value equal to the hidden field.
Protected Sub dlInfo_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataListItemEventArgs) Handles dlMnfo.ItemDataBound
Dim lblFullDeptCompare As Label = CType(e.Item.FindControl("lblFullDept"), Label)
hdnFullDept.Value = lblFullDeptCompare.Text
End Sub
And finally, the sql portion, where the value is passed as a parameter...
Protected Sub doInsertActivation()
Dim conn As SqlConnection
Dim comm As SqlCommand
Dim reader As SqlDataReader
Dim connectionString As String = ConfigurationManager.ConnectionStrings("xyz").ConnectionString
conn = New SqlConnection(connectionString)
comm = New SqlCommand()
comm.Connection = conn
comm.CommandType = Data.CommandType.StoredProcedure
comm.CommandText = "abc123"
comm.Parameters.AddWithValue("Department", hdnFullDept.Value)
conn.Open()
reader = comm.ExecuteReader()
reader.Close()
conn.Close()
End Sub
Yes, this works, but I just feel like I need to learn a more efficient way of doing this, as I'm constantly grabbing data and inserting it into sql.
I have a form that has a MAC Address field and a Password field and I have the chrome auto-fill options turned off, but when I load the page, chrome thinks the MAC Address should be an e-mail address and puts an e-mail address in there and for the password, it puts a password in there. Is there a way to prevent this behavior? Is there way to do this programmatically on page load, I tried clearing the fields, but that doesn't work.

View 1 RepliesCan I reach the value of hidden fields in controller action ? And how ? Do I put it in the model somehow ?
EDIT: some code example how to store something in hidden field and retrieve it on postback.
According to MSDN hidden fields section,
In order for hidden-field values to be available during page processing, you must submit the page using an HTTP POST command. If you use hidden fields and a page is processed in response to a link or an HTTP GET command, the hidden fields will not be available.
If I add a HiddenField control at design time and set a value in it at design time or in the Init event in ASP.NET, why would I not be able to read/process the value when a page is first requested?

According to MSDN and the MCTS self-paced training, asp.net can use Hidden fields for client-side state management. The book material goes on to say view-state is more secure than hidden fields because the data is encrypted. I must be missing something here. I setup a Label and made it hidden. I can store data in this hidden label and it won't even be sent to the client browser. This not only works like server side state (note the runat=server), but this seems more secure than view-state because there's no need for encryption as the client can't even see the field.
<asp:Label ID="Label1" Visible="false" runat="server">secret info</asp:Label>
<input id="Text2" type="text" style="visibility:hidden;" value="secret 99" />
