out: (it's a asp:HyperLink NavigateUrl )
String.Format("~/Reports/Logs/Option_History.aspx?OptionID={0}&time={1}", id, time)

<asp:QueryStringParameter Name="time" QueryStringField="Time" Type="DateTime" ConvertEmptyStringToNull="true" />
I have a querystring. I want to encode and decode of this querystring. How i will do it in asp.net 2010 ,C#. My querystring is given below.
<a href='../Product_Page.aspx?id=<%#Eval("PSubCatId")%>&scat=<%#Eval("SName")%>&cat=<%#Eval("Name")%>&cid=<%#Eval("PCatId")%>' style="text-decoration:none"><asp:Label ID="Label2" runat="server" Text='<%#Eval("SubCatName")%>' ></asp:Label> </a>
In my asp.net+vb web. In a gridview there is a hyperlink filed . it works fine for all company except for company name like lerson & turbo . the code i used is as below
<asp:HyperLinkField
DataTextField="company"
HeaderText="company"
SortExpression="company"
DataNavigateUrlFields="company"
DataNavigateUrlFormatString="link.aspx?company={0}" >
<HeaderStyle HorizontalAlign="Left" />
</asp:HyperLinkField>
In company names with & it is not working...
I am passing dynamic form name value in url as querystring using following code
http://mysite/Source= + form.ToString() + ".aspx";
In other form I am reading querystring value
RequestSource = this.Request.QueryString["Source"];
Now I want to check that RequestSource contain "accinfo.aspx" or not, How can I check this?
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.

Let's say the current webpage name is ABC.aspx and I want to make two different webpages based on this page; ABC.aspx?Mode="A" and ABC.aspx?Mode="B" (By using querystringparameter). When the user opens ABC.aspx?Mode="A" page, I want to show below gridview but when the user opens ABC.aspx?Mode="B" page, I want to show below gridview except "Gender" column.
Using this call;
<asp:AccessDataSource id="AccessDataSource2" runat="server" DataFile="_database/92592_Web.mdb" SelectCommand="SELECT *, (SELECT MAX(ID) as Max_ID
FROM myMovies) FROM [myMovies] WHERE ([ID] = ?)">
<SelectParameters>
<asp:QueryStringParameter DefaultValue="1" Name="ID" QueryStringField="ID" Type="Int32" />
</SelectParameters>
</asp:AccessDataSource>
How can I use "Max_ID" as my DefaultValue? So that basically if the page gets passed without a parameter, the SQL will use the Max(ID) as a default. Can I use Max_ID as a DefaultValue?
I'm an old .asp developer still on the learning curve of .NET so some of this stuff is a little daunting. In .asp doing something like this was pretty easy...

My question is: how can i create my own parameter based upon the QueryStringParameter?
Example:
[Code]....
I now called it QueryStringGuidParameter.
The purpose of this is: I'm not sending any querystring's via the aspx?querystring other thasn aspx?guid={guid identifier}.I hope my code below explains it al little bit.
[Code]....
A soon as a page Redirects f.i. with this example
[Code]....
Instead of calling Response.Redirect i call the Redirect i created. This transforms the querystring in a session with a guid and parameter. The Redirect only sends the guid in the querystring. and the receiving page picks up the guid and translates it back into a querystring.
Purpose is you have a secure way of dealing with info sending via querystrings. Lets say in the past you could easily get other info from the page by just changing a value in the key send via a querystring. In my case lets say the user request a Customer "A" with querystring ?ID=1.
Simple change the query in the addressbar to ?ID=2 (or something else) would give him another customer. Maybe a customer he is not allowed to see. (Of course this can be prevented also in the business layer, but that's not the point.)
So if i simply could create a new QueryStringParameter lets say called QueryStringGuidParameter which i can use in the ObjectDataSource but ideally just for all controllers which are able to use the QueryStringParameter , i don't have to go into code behind and set the SelectParameters in there.
if I can save the querystringparameter to session state, I want to use the parameter in code behind. Or is there a better way to do it?

Here in below code i have used querystring for sending imagename from this page to another page. Now i just want that with this imagename in also want to send span element's text with same querystring.How can i achieve this?
[Code]....
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 created a UserControl and added a public DateTime property. I want to set this property in Markup (ie. <cc1:MyControl runat="server" id="MyControl1" DateTimeProp="1/1/2010" /> ) however I live in a place with a dd/mm/yyyy date format so it complains if I set something like "20/1/2010". Is there a way to set markup in my local datetime format or do I have to conform to "mm/dd/yyyy"?
View 2 RepliesI have a problem:
I've created usual Controller and View(Edit view) for editing my Entity (EntityFramework)
Here is view example:
<div class="editor-field">
@Html.EditorFor(model => model.BirthDate)
@Html.ValidationMessageFor(model => model.BirthDate)
</div>
BirthDate is Nullable<DateTime>
but during loading my View I get this exception
The model item passed into the dictionary is null, but this dictionary requires a non-null model item of type 'System.DateTime'.
That's because of BirthDate is null in database but it is nullable and I expect that it just leaves the filed empty.
And I have Shared EditorTemplate:
@model System.Nullable<System.DateTime>
@if (Model.HasValue)
I have an XML string which contains Dates formatted "dd/MM/yyyy hh:mm:ss".
I'm loading this XML into a dataset using DataSet.ReadXml().
How can I ensure that this Date is stored in the DataSet as a typed DateTime so that I can Sort, Format and RowFilter on it accordingly.
My test harness is as below:
ASPX Page:
[code]....
obj.From = DateTime.Parse(txtFrom.Text, ci);
And it will give error String was not recognized as a valid DateTime. How it can be solved..
I have two examples to show you what I want to achieve here. But to point what's different about my question, Is that I'm having a parametrized URLs and I want to implement URL rewriting to my application. But I don't want to convert the parameter in the URL to be placed between slashes..."page.aspx?number=one" to "pages/one/" << NOT!
First example:
http://localhost:1820/Pages/Default.aspx?page=2&start=5
To
http://localhost:1820/Pages/page2
Second example:
http://localhost:1820/Items/Details.aspx?item=3
To
http://localhost:1820/Items/ItemName
But I'll still need all the parameters in the original URLs

var decodedUrl = HttpUtility.UrlDecode("http%3A%2F%2Fwww%2Eexample%2Ecom%2F");
I'm working with the google webmaster tools api and this api expects an URL as shown in the decodedUrl variable above. Every single character is encoded there.
When i use the httputility encode function i get the following result;[[URL] How can i use the encoding variable in such a way that every character in the url is encoded?

I am trying to store a SQL Server datetime into MySQL datetime field, but MySQL stores the date value as all zeros. I use this function to trim the fractional part from the SQL Server datetime, but get the same result when trying to store it in MySQL.

I am trying to get data from mysql database and store in sqlserver database. i am getting the following error
The given value of type MySqlDateTime from the data source cannot be converted to type datetime of the specified target column.
I know that I could use HttpServerUtility.UrlTokenDecode Method to do the job. But the problem is that I am using .NET 1.1 and this method is only supported in .NET 2.0+. Also I found that Convert.ToBase64String method is not an option because of the differences addressed here. So what other options do I have? Do I have to write my own converting method?
View 1 RepliesWhen storing a value in a cookie using C#, what is the best way to encode (or escape) the value so that it can be retrieved and decoded/unescaped reliably?
I'm not talking about encryption.
I want to reliably and easily Uri encode paths such as "/folder/foo%bar" to "/folder/foo%25bar".
I would have hoped that HttpUtility.UrlPathEncode would do the trick but this method only escapes spaces. I don't want to url HttpUlity.UrlEncode as this will encode "foo bar" to "foo+bar" - which ain't what I want.
