View 4 RepliesThe following code works well as long as I pass a querystring value to the datalist.
Private Sub BindGrid()
Dim id As Integer = Integer.Parse(Context.Request.QueryString("id"))
Dim strConnString As String = ConfigurationManager.ConnectionStrings("Conn").ConnectionString
Using con As New SqlConnection(strConnString)
Using cmd As New SqlCommand()
cmd.CommandText = "select Id, Name from tblFiles where Id=@Id"
[Code] ......
However, the page errors with the message "Value cannot be null." if I don't pass a value. I know that DataList does not have an EmptyItem Property like a Gridview control. I do not want the page to error if I don't pass a value. Need info to deal with empty values in a datalist.
Most websites have pointed me to this code to use:
<FooterTemplate>
<asp:Label ID="lblEmpty" Text="No Result" runat="server"
Visible='<%#boolean.parse(([b]list[/b].Items.Count=0).ToString())%>'>
</asp:Label>
</FooterTemplate>
The 'list' throws an error. The error is "Too few type arguments to 'System.COllections.Generic.List". I am not sure if the code is written in C# and that is what is causing the error. It seems that it should work but I can not figure out the 'list' error.
I need to have a video on my asp.net webpage, but the source of the video depends on a few of the querystring params. How would you approach this?
(Ideally I'd be able to control what video shows in the embeded section and if the embeded section is even present)
upnlA: in this updatepanel I show search results based on querystring parameters
upnlB: here I have a checkbox list X which filters the search results (allows for narrowing the results)
Now when a checkbox in list X is clicked, I do an autopostback, then I need to update the querystring (current URL in users browser) and also update the search results.
I have no idea how I would go about this! Im seeing difficulties in changing the URL without doing a response.redirect/server.transfer and reading from the querystring to update the search results.
I don't know how to write the code to change the querystring of a page without to update the page in the onclick event of a Button.
View 2 RepliesI'm trying to use the value of a QueryString as the file name for an image. I figured I could use a textbox to get a string value and then use that but I don't see how to use my Variable in the code page as a value in my .aspx page.Also, I thought there might be a way to set the value of an image control directly...I have this so far:

I have a gridview in which I have several editable fields. The user wants a non-editable field to be modified if another field is modified in the same row. e.g. if Age>=65, Status should ="Retired"
I am using the following demo: [URL]
to create a bulk edit gridview so some columns are automatically editable and others aren't, with a single update button. I can set Status="Retired" in the xml generated, or as a rule in database table. But I'd like the status field in the gridview to change when Age is modified and to be shown to user before they press the single Update button. I'm using update panels and ajax on the page also.
I have a master-detail page consisting of a databound GridView and ListView. It's pretty standard - when you select a row in the GridView is shows up the ListView. The problem I'm running into is when I want to link to that page with a specific row pre-selected in both views. It seems like it should be easy enough, but I just can't figure it out. Currently, the ListView is connected to the GridView with a ControlParameter in the SelectCommand.

I've got a request to redesign the web application to allow support for up to 3 users (before there was data only for one people on page). Since I don't want to build entire page again I wonder how is possible to replace value which is for example:
[Code]....
with value retrieved from querystring?
Users are displayed on page in row: querystring value ID(for example 123), QS value ID2(for example 231), QS value ID3(for example 343).
Users are all stored in one row of the same table. If second user is selected then value of his/her should be taken as value of ID.
I'm using quite a lot <%# Eval ("ID")%> on my page and I don't want to replace it with some object but just overwrite it's value according to querystrings values.
I hope this doesn't sound too complicated as the real problem is fairly easy but don't have ideas how to deal with it. I've thought I can put to replace the value retrieved from SP but I can only change parameters. And ID is not select parameter.
