View 1 RepliesI am developing a webapplication with maser page. there i have a lebel, control. i need to update its value from the content page, and only by the javadscript.
i am doing:
[code]....
The second question is, how could i initialize(to NULL) my master page value from the content page .
I have a master page:
<%@ Master Language="C#" AutoEventWireup="true" Codefile="AdminMaster.master.cs" Inherits="AlphaPackSite.MasterPages.AdminMaster" %>
Then I have a public variable:
[code]....
Does this make sense? When I try combinations of Master.blnShowDialogue, or blnShowDialogue = , etc etc nothing seems to work.
The name 'blnShowDialogue' does not exist in the current context
I have the master page code behind like this:
public partial class TheMasterPage : System.Web.UI.MasterPage
{
string test = null;
protected void Page_Init(object sender, EventArgs e)
{}
}
When I'm in the Page_Load function in the code behind of the content page, I don't see the variable test as being available. Am I declaring it wrong?
I am trying to reference a variable within my MasterPage but I am receiving errors.
I have tried
<%@ MasterType" %>
which gives the following error:
Compiler Error Message: CS0030:
Cannot convert type
'IPAMIntranet.IPAMIntranetMaster' to
'ASP.ipamintranetmaster_master'
and
string tVar = ((MyNamespace.MyMasterPage)Master).variable
which gives the following error:
Unable to cast object of type
'ASP.ipamintranetmaster_master' to
type
'IPAMIntranet.IPAMIntranetMaster'.
I have a value in string i want to use that value on next page.
How can i access it with previous page property?
Or is there any other way to fetch value store in string variable on next page?

I am having problems in retaining the string variable which I defined on the top of my scoop, everytime when page loads the string value becomes null. below is the snippet of the code:
public partial class Caravan_For_Sale : System.Web.UI.Page
{
string check;
PagedDataSource pds = new PagedDataSource(); //paging
[Code]....
The string check becomes null everytime when the dlPaging_ItemCommand becomes active(page loads).

2) I have a content page TextBox with data equated in the C# code behind:

tbxCategoryID.Text = CategoryCode;
... sample data "Furniture1135" for TextBox.
3) I need the MasterPage HyperLink4 navigateURL to be

My Asp.Net calls a SQL sproc and returns a XML file as a string. This is what I need to do:
- save that string into memory (as a file);
- pop up a dialog box asking the user which path he would like to save the file;
Any samples out there...how do I achieve this task in Asp.Net C#?
I am using the following code to write the contents of a string (converted to a byte array) to the client in ASP.NET/C#
byte[] data = StrToByteArray(strData);
Response.ClearContent();
Response.AppendHeader("content-length", data.Length.ToString());
Response.ContentType = "text/plain";
Response.AppendHeader("content-Disposition", "attachment;filename=" + fileName);
Response.BinaryWrite(data);
Response.Flush();
fileName is the name of the file ending with the file extension (.pgn). However, the file is saved as a .txt file, ignoring the extension that I am giving it. Would this have to do with the Response.Contenttype = "text/plain"? How can I get the Open/Save dialog to display and save the correct (.pgn) filename?
Also, if filename is a string separated by dashes or spaces, when the Open/Save dialog comes up, the filename is not displayed in its entirety but it is truncated where the first dash (-) or space (or comma) is encountered. How can this be remedied?
My project has the following repeater menu shown on the Master Page. I need this menu to remain hidden until the user logs in. How do I access from content page?

I'm using this Ajax script [URL] to load content from an aspx page on another server than the page calling the content. So far I've learned that this is a no go. The problem seems to be that when using an absolute link to content the script fails as apposed to using a relative link.
I've searched the web for about 10 hours now, and I still haven't found what I'm looking for.
I have searched the web for the answer and saw that mostly variables are saved in viewstate on page.prerender event. Then the value of the variable is set back in page load event.However, when I save a variable in viewstate on prerender or load events, how can viewstate store the value of the variable after it is changed dynamically on codebehind?
Let's say, after page is loaded, user clicked a button which changes the value of the variable in its onClick event. Then the postback event raised since the button was clicked. According to me, the new value should have been lost and cannot be saved in the viewstate if the variable is saved in the viewstate only in prerender event. Because on postback the prerender event wont fire and the value cannot be saved.
Shouldn't I save the variable in the viewstate just before the postback event rises?? If so, how can viewstate store the new value of the variable if the viewstate is saved in prerender event?
which page need to be checked. Master or Content. I dont think there is anything wrong in the content page.
View 1 RepliesHow to display the string data stored in a string[] variable into gridview?
View 9 Replies I am using the ajax control toolkit tabcontainer with 5 tab panels inside of it. Each tab contains areas where one must input information. The page also contains add, edit, and delete buttons with gridviews above them. What I am trying to do is to make the user save or cancel changes when they change the activetab. I am using a javascript confirm box but I need to try to retrieve the value of what is pressed from the javascript box to decide whether to discard the changes or stay on the page and make the user finish the input. Is there any way to save the value from the javascript box into a variable so or must i try something else?
PS I wasnt sure whether to post this in the javascript section or the asp.net section since im using asp.net with c#.This is kinda what im using but would like to turn it into a confirm box and pull the true or false value.

How do you do this?
My application is MVC Web App Chat Room , it supports following features:1.Create/Join/Close room 2.Send message in room (just live message, offline message might be supported in future)I have done logic for application, but I'm considering where to save chat room data (message,room information, and users in room) ? I see there are 2 options:1. Application variable2. Using file or database-What if I saved in Application variable:In case of there are 2000 rooms and 10000 users online, mean I have to persistence in Application variable (actually in RAM memory) information of 2000 rooms, more than 10000 message (text), these numbers might be increased by second if there are more users online in real time. and what's next ? I don't know what will happen to server, crash ? or my web app will be terminated ? whatever I don't want both results !
-What if I saved in file or DB (i.e: SQL Server DB) Because of web application, clients have to send request every 1 second to fetch data (messages and user list in room). So in case of there are 2000 rooms and 10000 users online, means they will make 10000 requests every 1 second to DB. I don't know what will happen to DB, there are a lot of connections and in EVERY 1 second, can DB still be alive to serve request ?I don't know where saving is good now because both seem are bad solution
