View 7 RepliesI have datagridview with paging enabled. But when I want to move from page to another page in the grid, then it only works when I press the 2nd time on some other page. I read some on the internet that I need to bind the data of the gridview but the thing is, I cant bind the data again because the gridview was filled with data in the page_load from querystring and I dont really want to go over the querystring again in the PageIndexChanging function.
protected void searchGridFA_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
searchGridFA.PageIndex = e.NewPageIndex;
}
So why does the page changes only from the 2nd time I press it?
The DataGridView shows 10:00:00 but I needs 10:00 AM
If my time is null in the Database I got 00:00:00. But I need only 00:00
I had applied like this.
dgv.Columns("StartTime").DefaultCellStyle.Format = "h:mm tt"
dgv.Columns("EndTime").DefaultCellStyle.Format = "h:mm tt"
This is not working.
This is for Win Application
I got this from [URL]
i have a datagrid view with two columns. the first column is readonly and the other is editable. now i want every cell of the second column to support for mulitilines in each cell. i want to press enter key and come to the next line in the same cell. im using c#.
View 1 RepliesI am new to asp.net and was trying to use datagridview in my webform. I was able to bind it to my database but I cannot make the datagridview's buttonfield respond. It seems the grid's SelectedIndexChanged event is not being fired or has issues with postback. Even a very simple statement is not being executed by the program e.g.
protected void grid_SelectedIndexChanged(object sender, EventArgs e)
{
detailsLabel.Text = "asdfasdfsafasddf";
}
It seems the SelectedIndexChanged is not being fired. I have checked my IE and scripting is enabled.
I am using VS 2008 and IE7. Can anyone share a solution on how to solve this issue?

View 2 RepliesI have a form which inserts data in DB on Submit button click but the problem is when client click the button multiple times its sends multiple create requests means multiple button click events for the same time of same data, which must not be.
I tried to disable the button when client click the Submit button first time but after this it does not call server click event handler or not fire the server click event once it got disabled.
How to handle this multiple click problem..
I used the following code to disable the button

I want to use a function in the code file of ASP.NET such that everytime the function is called, its value increases by 1.I thought of a way but it didn't fully work out. I created a class for this and used a static variable in that but the lifetime of static variable in asp.net is till the time the app does not close.
public class Class1
{
public Class1()[code]....
I have a table(ShiftCalendar) that lists a letter and a datetime:
Shift Date
A 3/2/2010 8:00:00 AM
B 3/2/2010 8:00:00 PM
I can run a select query that looks like this:
SELECT Shift
FROM ShiftCalendar
WHERE (Convert(nvarchar(10), GETDATE(), 101 = Convert(nvarchar(10), Date, 101))
This will return both values, but I need to to check the time of day to determine which Shift to return. I have been messing around with the IF ESLE and CASE but I can't find a way to tell the select statement what the time of day is.
I have information in a database wich need to be shared with a java (Flex) application that uses the SpringGraph component to show a network layout.
Since that component creates the graphic structure based on XML, I believe Web Services are the best solution.
The problem is, here's an example of the component's XML:

The sample above means that "e1" is connected to "e2" and "e2" is connected to "e3".
I know how to create a web method that return a "single" class. Like "int IsValidUser" or even "User UserData", but how can I return that structure?
I have a web service method which i'd like to return multiple rows from a datatable.
I am familar with returning values from web service methods but not multiple rows from a datatable. What is the best way to go about doing this? Do I need to return an array or list<>?
My code method is setup like this.
[WebMethod]
public void UpdateBold(int count, float lat, float lng)
{
DataTable dt = new Gallery().DisplayNearestByLatLong(count, lat, lng);
// return code here
}
I want to return two tables using a mySqlDataReader and load the results into two datatables.
using (MySqlConnection connMySql = new MySqlConnection(global.g_connString))
{
MySqlCommand cmd = connMySql.CreateCommand();
cmd.CommandText = @"
SELECT * FROM table1;
SELECT * FROM table2;
";
connMySql.Open();
using (MySqlDataReader dr = cmd.ExecuteReader())
{
DataTable dt1 = new DataTable();
dt1.Load(dr);
dr.NextResult();
DataTable dt2 = new DataTable();
dt2.Load(dr);
gridView1.DataSource = dt1;
gridView1.DataBind();
gridView2.DataSource = dt2;
gridView2.DataBind();
}
However, when I run this, only one gridView is populated. Can I use NextResult in this way, or is there a better way to acheive this?
I have two methods that do the similar thing. There are small differences here and there, which I can control by passing arguments to them when I call them, so I can effectively merge them. However one returns a string, and the other one an ArrayList. On the top of my head, I could merge them and return an Object, and then get the information I need. Is there a way though to return multiple types in the method's signature? What's the proper way to implement this?

Reporting system has list of available reports on a web page. When user clicks on a report new browser window opens, server starts to prepare report (winword document) and then sends it back after 2-10 seconds.
Code in the handler looks like the following:
context.Response.AddHeader("Content-Disposition",
"attachment;filename=report.doc");
context.Response.BinaryWrite(reportDocument);
Is it possible to prepare html content immediately send it back and then continue with time-consuming report preparation not closing connection?
I need to write a webservice that returns multiple rows from a table. I am familiar with return of a single object.
I am calling a stored procedure in the webservice that populates a data table.
I guess I need to define an object collection to be returned. Should this be an array or can I return the data table itself?

I am working on a website hosted with GoDaddy, SQL Server 2005. I have a table in my SQL Server database with a full-text index. On my website, a user can type in search terms and the terms are then passed to a stored procedure in the database which performs the search. The first search takes about 45 seconds to get results. Subsequent searches return results immediately. I found a description of this problem in a Microsoft knowledgebase article:http://support.microsoft.com/kb/915850/en-usGoDaddy tech support says I need to purchase a dedicated server to make the changes suggested in this article.Surely there is some other solution. Does anyone know how to avoid this delay without changing the server configuration?
View 1 RepliesI have the below c# method to populate an asp.net frontend control from a linq query. The only valid way I seem to be able to reference the query variable "result" is if I use the attribute "SingleOrDefault" but unfortunately this forces my query to return just the one single set of data for every unique primary key UserId value from my query, where I require the unique data attached to each different UserId value to be returned, how can I achieve this using linq? Note, I am passing the UserId value into my method from a public variable which is also below.

I need to gather information (via GET) from several other websites (not under my control), do some processing (specific to each source) on the data returned, and then print all the info out to the user.
Right now I'm making the GET request to website A, waiting for it to return, processing it, then calling website B, and so on... Obviously this is too damn slow. I'd like to make async requests to A, B, and C, then process each response as it comes back, and once I have all the responses, print it all out to the user.
I'm allowed to use classic asp or vb.net. I'm more familiar with classic asp but I'm willing to learn...

Is it possible to return multiple values from a stored procedure? Basically, if I execute the stored proc on the C# side, then on the SQL side I do multiple calculations. Let's say I have 5 int values I need returned to the C# side.
