Select evet fires twice using ObjectDataSource GridView [modified]

This will obviousy be done in javascrpt. I'd be amazed if it's not been done before, have you tried google ?

That doesn't do what you want, but it seems a good place to start.

Hello!

I have a page with rezult of big query, I use GridView & ObjectDataSource to display them, but unfortunatly I found that ObjectDataSource fires Seletc twice Frown | :(

I don't know why it happens. There is no databind on the page.
Page has masterpage. While debug it looks as PageLoad of page is finished and fires first Select, than the second Select fires after the MasterPage PageLoad finishes. Confused | :confused:

Thank you for help

Why does it have to work that way ? I wonder if you can set up two web apps in IIS that are called Client and ATP and point to the same base directory ?

You can use URLRewriting. You have to create a HTTPModule which listens the requests. If the incoming request is coming like http://www.xxx.com/Client/Add.aspx, redirect it to your real Add page with some querystring value to indicate it's a client request. Same way do for ATP also.

Context class comes with RewritePath() method. Make use of this.

Accessing text file with URL

Hi people,

I have a web service method that I would like to use to access a text file over the network, say the file is located at http://someserver.com/somefolder/myfile.txt. I have been searching with google and all I could find was how to read an XML file by providing a URL in this article: http://support.microsoft.com/kb/307643[^]

I was wondering if there was a way to do the same but with text files instead of XML files. It seems that TextReader or StreamReader do not access a URL as the path of the file.

Any insights are appreciated.

Thanks Smile | :)

Talal,

You can make use of WebClient class. This can be used to download data from remote URL. See the following snippet explains how you can read the text file from URL

System.Net.WebClient wc = new System.Net.WebClient();
byte[] b = wc.DownloadData("http://someserver.com/somefolder/myfile.txt");
string Text = System.Text.ASCIIEncoding.ASCII.GetString(b);

That's it, you will get text file content in Text variable. Now use some kind of regular expressions to parse it and read the necessary content.

Hope this helps

Hi,

Thanks for the hint Smile | :)

I found 2 ways to do the job. I will post them here maybe it would help others having the same problem.

Using your code, I found that if we use the DownloadString, it works too. We can write:

WebClient wc = new WebClient();
string s = wc.DownloadString("http://someserver.com/somefolder/myfile.txt");

this will put all the text file in s. We will get of course \r\n each time there is a new line.

Another method can be used which can allow us to read line by line:

WebRequest wRequest = HttpWebRequest.Create("http://someserver.com/somefolder/myfile.txt");
WebResponse wResponse = wRequest.GetResponse();
Stream myStream = wResponse.GetResponseStream();
StreamReader sr = new StreamReader(myStream);
string firstline = sr.ReadLine();

This is even better as we don't have to parse the string to remove the \r\n or other special characters.

Voila. Thanks again for the hint Smile | :)

Hi,
I have a user control in which I have a save button.
When this button is clicked data will be saved to the database.

After button clicking if I refresh the page, then the same button click event is called again which is adding the data again in the database.

I tried all possibilities i found, but didnt able to get the solution.

Could anyone please let me know the solution for this.

Thanks,
Madhuri.

The problem is that a refresh does the postback again. The solution is to redirect your page in your button click event after saving. If your page has some state it needs to show, then pass a variable on the URL that reloads that state. Then, a refresh reloads the page with the variable, and shows the state, but does not execute the save event.

I have 3 drop downlist boxes upon whose selection a new record adding section will be displayed.

But If I redirect the page, the dropdownlistboxes values will be reset, which is not expected.

Well, unless you put the selections in the URL, they will obviously reset. You can't have it both ways. All state will be held in viewstate, or all state needs to be on the URL ( or in the session, but that should be avoided ).

Hi There,

I believe you dont want the button Click to be called again.
I am not sure the solution will work or not, but try this,

Javascript

function DisableButton(buttonElem) {
buttonElem.value = 'Please Wait...';
buttonElem.disabled = true;
}

ASPX
<asp:button id="btnSubmit" runat="server" Text="Submit" />

C#

protected void Page_Load(object sender, EventArgs e)
{
btnSubmit.Attributes.Add("onclick", "DisableButton(this);" +
Page.ClientScript.GetPostBackEventReference(this,
btnSubmit.ID.ToString()));
}

I got this solution from the website itself.
I hope it works for you....

Thanks
Cheers

Re: Ambiguous match found.?

I don't think this will work. It stops a postback from clicking more than once, but not from a refresh.
