I use the UpdatePanel, which works like I want. I do have a problem with refreshing the website when I want to edit data. I think the problem in the QueryString.
Can be done any other way to I get ID?
My code:
[Code]....
Delete command works because the position is obtained automatically. When editing is required I get the Id, since I do not use the classic command Edit.
The 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 have a web apps that has different relations data, displayed in the repeater controls. One of them is When I click the Book it should display chapters related to that book.
It works most of the time but the problem is: if the book contains '&' it'll truncate the data after that and no chapter data display due to no matching with the book name.
I did like this:
[Code]....
and in chapter_Matches.aspx:
[Code]....
Let say the book name is:
'chemistry' it works in this case and in the chapter_Matches.aspx page the str=chemistry and the url is chapter_Matches.aspx?book_name=chemistry
but let say book name is chemistry & physics
url will be chapter_Matches.aspx?book_name=chemistry & physics but the str value at chapter_Matches.aspx will be str=chemistry.(physics will be truncated after & sign)
and no data display due to not matching the book name.

(to avoid user to change the parameters and see other messages)
View 4 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 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 formview that does a simple 'SubTotal' calculation based on some checkbox inputs. I write out the subtotal to an asp:label control. I want to be able to also be able to write that value into the QueryString so I can carry it over to another page. I can't seem to access the label from my codebehind (intellisense doesn't find it).

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.
