Is it possible to popup information according to the value of an integer,
if it's inferior of a number, show up something and if its superior then something else.
How can I manage this .... ?
I want the user to click the link then the window pops up, but I want the data inside the window to be pulled from a database, and I need to repeat this process for 5 links that are also pulled out of a database. Say the most popular items for the month. My question is how would this be best accomplished? Jquery, or AJAX. I am just trying to see which would be the easier way to go about coding this with .net and C#.
View 1 RepliesI have a label and modal pop up (ajax control toolkit modal popup) in my parent form. The modal popup is inside an update panel and it has a check box. Once the user is done making the selection I would like to bring back all the selected value and write it to the parent control. So I have a save button in the popup. Once the user hits save this is the code he runs through:
Protected Sub btnSaveClick(ByVal sender As Object, ByVal e As System.EventArgs)
In my code I am using a popup window to display extra information. I also have the ability to export the information in the main window to Excel.The problem is, after the window pops up -> I see the info -> I close the popup window -> but if I try the export to Excel button, it throws the exception "null object referrence" (if I use a try/catch, the exception doesn't occur - but I don't get any information). In the export function I am doing something like this:
{
//some code .... here
con.close();
session["dss"] = mydataset;
}
In the export button click event:
system.data.dataset dss = (system.data.dataset)session["dss"];
//then some work on this
I think, probably when the popup window opens it ends the execution and that's why when I come back to the main window and try the export button the values for the tables and all goes out of scope.Also, if I refresh the main page after closing the popup window I don't have any issue and can export the data.
I have a list of events that have been retrieved from a database a bit like this: Easter St Patrick's Day Christmas Independence Day ... I would like to make them links and when you click on the link it raises a modal popup and displays a bit more information from the database about the event. So far, I've set up the ModalPopupExtender like this on my page:
[Code]....
I thought the links might look something like this:
<asp:LinkButton ID="btnShowPopup" runat="server" OnCommand="ShowDetails" CommandArgument="Test">Event 1</asp:LinkButton></p>
[Code]....
I'm not quite sure how well this will repeat though. It looks like I'll have to have a ModalPopupExtender for every single link which doesn't sound very efficient. Am I doing this right?
I need to open a popup in the middle of my function, and in the popup i have the gridview control, i need to select one row in the gridview and after closing the popup it should come back to the same function and to same point where i opened the popup. i am using the model popup but this popup is populating after executing all the function, but i need to select one value and need to continue my function
View 3 RepliesI am making an online form (literal form) that needs to have a certain function: when the user enters a 5-digit number, the form should automatically query the MS SQL DB and retrieve information associated to that number and populate other form elements (text boxes, etc.) accordingly.
So say the # was 12345 and in the DB, the record matching 12345 has name=Fred. So, when I enter 12345 into the form textbox, the name text box should be automatically populated with Fred in it.
If this is not easily achievable, I guess a submit button beside the 5-digit number text box can do.
I am still learning my way around ASP.NET and Visual Studio 2005, however I have ample experience with HTML, CSS, JavaScript, C/C++. The ASP.NET app is to be written in C#.
i need to convert from string to integer, i tried in all ways but no luck.... here is my code
[Code]....
here in checkdDoorID integer value is available, but i can't convert to string. i tried ctype,parse but nothing worked out. i need the value in integer so that i can stored in DB as primary key.
I need to convert a timespan into an integer. I have two dates that I am subtracting one from the other, returning a value in days. I then need to perform some arithmatical functions on that value but I cant figure out how.
View 5 RepliesIn the standard forms authentication, users are identified by a Guid. I want to give my users an UserId of type int (doesn't have to be the primary key, just something to do lookup's on).
Is it safe to add an additional column to the aspnet_users table, or should I create a new table which FKs to the UserId column and has a Unique column which generates the integer ID?
The later sounds like a bad performance hit to take just for the sake of an int!
EDIT I want to create URLs like those on stackoverflow. eg.[URL] where the User ID is an int. For that reason I don't want to use Guids.
A very easy one hopefully - what expression can I use to validate an integer to ensure it is greater or equal to zero, but less than 2,147,483,647 (i.e. the maximum value of an integer)?
For example 0 =< x < 2,147,483,648

View 1 RepliesI'm trying to use a variable returned from the database as an integer. My thought is to use a Link button and when my user clicks it, it should open a new window. However, its giving me an error stating the value is in the wrong format. Here is my link button code.

View 2 RepliesI have an sproc which selects data out of my table. The column can return integer or NULLs.
I get the 'failed to enable constraints error' when databinding. If I go to my tableadapter and select my column there is a NullValue property which has 'Throw Exception, Null, Empty'. If I try and unset the exception option it tells me only strings are allowed this. However the 'AllowDBNull' option is set to TRUE.
What is the alternative and will this be fixed in 2010?

This time arround i want to exctract the integer value and use it in the if statement for testing.
I however face a problem in the fact that though i can select the particular cell in a table i still get a table adapter which is not what i need and is not covertible to int value.

I have a GridView that records can be added to.There are only 2 fields in the table that the records come from which are date field and an integer field.The date field is fine "as is".The problem is that you can't format the integer field.I have tried every way that I can think off.The last 2 ways that I have tried have used String.Format because I am using EVal and with Eval you can supply anoptional second parameter to specify a format for the returned string.I have tried in both html and code behind , html gives an error message but the code behind (code behindthe RowDataBound method) doesn't give an error message:In the html looks like:
<ItemTemplate>
<%# Eval(("inFrmDate").ToString(), String.Format("{G}")) %>
