How To Encode An Url As Base64 String

Sep 16, 2010

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?

Stored Procedure:

I'm sure i've got this entirely backwards. However if I change the NULL value in the stored procedure with some string value (eg."Donkeys") it pulls all the values that contain "Donkeys" into the datalist on my results page.

Trying To Test Extension Method That Converts A List Of Strings In A String Comma Separated?

Aug 27, 2010

Im trying to test my extension method that converts a list of strings in a string comma separated:

public static class Extensions
{
public static string ToCommaString<T>(this IList<T> input)
{
StringBuilder sb = new StringBuilder();
foreach (T value in input)
{
sb.Append(value);
sb.Append(",");
}
return sb.ToString();
}
public void TestExtension()
{
IList test=new List<string>();
//test.ToCommaString doesnt appear
}
}

The issue is that in the method TestExtension i cant use ToCommaString method. Do you know what's happening?

Could i make available for all my web application this extension method registering in web.config or something similar?

DataSource Controls :: Benefits Of Using ObjectDataSource Over Normal Method Calls?

Jul 6, 2010

In my application at some places we have used ObjectDataSource and at other normal method calls to retrieve data.My question is then what exactly are the benefits of using ObjectDataSource ?In the example below "CODE ONE" makes a call to the Business Layer and then Binds the results to the Grid abd "CODE TWO" is using ObjectDataSource to do the same.Then how is ObjectDataSource better?

SuitableApplicant sa = new SuitableApplicant();
IList<HD.Recruitment.SuitableApplicant> list = new List<HD.Recruitment.SuitableApplicant>();
list = HS.Recruitment.RecruitmentService.GetSuitableAppls();
GridView1.DataSource = list;

Web Forms :: Error - "Invalid Characters In Base64 String"

Sep 15, 2010

I'm running into following error: "The viewstate is invalid for this page and might be corrupted." "Invalid character in base64 string." Only with IE 8.0. Firefox works fine. The persisted view state is

"/wEPDwULLTE2OTU5NzE1MjYPZBYCAgMPZBYCAgEPZBYCAgMPZBYCZg9kFgQCBQ8WAh4FVmFsdWUFCGRpc2FibGVkZAIHDxYCHwAFCGRpc2FibGVkZGSt4I2szqsXGPwfecanpFW+cIZNhQ==,/wEPDwULLTE2OTU5NzE1MjYPZBYCAgMPZBYCAgEPZBYCAgMPZBYCZg9kFgQCBQ8WAh4FVmFsdWUFCGRpc2FibGVkZAIHDxYCHwAFCGRpc2FibGVkZGSt4I2szqsXGPwfecanpFW+cIZNhQ=="

i.e. two identical parts separated by a comma. I'm using a form with both jQuery and UpdatePanel. I've inspected the __VIEWSTATE hidden field before the post __doPostBack and $I.System.InvokePageMethod. In both cases the viewstate does NOT contain the comma. where the field gets doubled up with the comma inserted? Or how to fix.

If it is possible what the approaches I can adopt?

DataSource Controls :: SqlDataSource And Parameters Query / Trying To Accomplish Is Building Dynamic Query

Aug 22, 2010

1. I have a GridView on my page and it uses sqldatasource with parameterized query. What I want to do is, on page load (where nothing has been selected so no parameter supplied), I want it to query everything (something like SELECT * FROM [this_table]) but since my SelectCommand is something like

SELECT * FROM [this_table] WHERE [this_column] = @someParameters AND [that_column] = @someParameters.

Can I play around with default value to achieve something like that but how ? Now, when the page loads, it doesn't show anything (No Gridview).

2. On my page, I made something like (username, gender, address, and more) and one single search button. That means, no single control enable auto postback. What I am trying to accomplish is building dynamic query

(if username specifed -> SELECT * FROM [this_table] WHERE [username] LIKE @username).

If both username and gender are specified (SELECT * FROM [this_table] WHERE [username] LIKE @username AND [gender] = @gender) and you know the rest. How can I do this using GridView and SqlDataSource ? To my knowledge, I can only specify one SELECT statement in a sqldatasource.

DataSource Controls :: Accessing FK From A Query Via Entity Query

Jan 21, 2010

I've got a query such as

Dim MediaQuery =
From m
In dB.DOWNLOADS _Where m.ID = id _Select

which returns a record from the database. One of the fields in the record is a FK to another table. I need to read this value to be able to set a dropdown based on the ID but I can't work out how to access it. For a standard record I can just do the following txtTitle.Text = MediaQuery.FirstOrDefault().TITLE

However with the foreign key it doesn't work like that. I've tried drpGroup.SelectedIndex = MediaQuery.FirstOrDefault().DOWNLOAD_GROUPS.ID where DOWNLOAD_GROUPS is the FK field but it returns Object reference not set to an instance of an object. If you're simply wanting to read some values from a single db record in the entitiy framework and one is a foreign key how should I go about getting the value?

Forms Data Controls :: Finding LinkButton In GridView1 And Write A String To Does Not Work?

Jan 16, 2011

I have a problem to write a string to a LinkButton that is located inside a GridView1. Now the hiarchy of controls is like this to understand how to Find this control:

TabContainer0 TabPanel5 TabContainer1 TabPanel7 Panel8 GridView1 LinkButton1 So LinkButton1 that we want to write a string to is located in a GridView1 which is located in Panel8 which is located in TabPanel7 that is located in TabContainer1 that is located in TapPanel5 that is located in TabContainer0.

So below is my code but no string is written to that linkButton, so I wonder if I miss something basic out here?
