I want to display sql query results in my web application (asp.net webpage) dynamically at the run time. But I don't know how to do that. Is there any control to do that? Or is there any code? Could you give some examples?

I am developing a web form for search capability. The search query should return records from three different tables. How to display these three table records in three different rows. The search query should get the results from Table 1 and Table 2. Table 2 and Table 3 has a parent child relation ship. Which controls can I use for this purpose?
View 5 RepliesI am trying to add some filters to a gridview that I am working on, and I'm wondering if it is possible to generate links or buttons above the gridview based on the years returned in the dataset. For example, if my dataset contains dates from 2001, 2009, and 2031 in my date column, I would like to be able to take that data from my SQL query (getting a distinct list of years is not an issue), and generate the buttons. From there, I would filter the data in the gridview based on the user clicking the buttons.
Is dynamic generation of buttons possible in ASP.NET? I do have some other ideas of how to accomplish the same functionality, but I would prefer to do it this way.
I am trying to build a SharePoint 2007 web part in Visual Studio. This web part should search a sharepoint list and display the results.
What I want to accomplish is to display the results as soon as the user stops typing, so no clicking button involved.
Probably, a combination of text_changed event and onkeydown javascript?
This sharepoint site is "Ajax-enabled", btw.
I am displaying some query results in a div (table format). Is it possible to do pagination in vb.net in a div . Because i am not using any list view or data repeater or data grid control.

I have a .Net 4 Chart Control bound to stored proc. For some customer selected queries the chart will be empty. I would like to display a "No data" message in the empty charting area so customers understand why the chart is empty. I haven't been able to find any information about how to do this.
View 1 Replies(Mods, move if I put this in the wrong place) I'm running queries against SQL databases, and I'd like for the results of my searches to appear in table form in an email that is then sent out dynamically. I currently have the results appearing in a Datagrid on a webpage which I'm then manually transferring to an email form to send. I'd like to streamline the process so I don't need to do any manual entry.
How can I have a table/datagrid/whatever in an email that gets populated with the results of a SQL query?
I have a gridview that I want to bind the results of a query to it once a user selects a value from a drop down list.
The query selects the same row from the same table but selects different fields based on the drop down list value selected
I get to the query selection but it does not refresh that page with the populated gridview.
Here's the code behind code
protected void ddlQuantity_SelectedIndexChanged(object sender, EventArgs e)
{
SqlConnection connection = null;
connection = new SqlConnection(ConfigurationManager.ConnectionStrings["PSI_DB_1ConnectionString"].ConnectionString.ToString());
connection.Open();
String nEstno = Request.QueryString["id"];
int id = Convert.ToInt32(Request.QueryString["id"]);
string SQLquery = "";
switch (int.Parse(ddlQuantity.Text))
{
case 1:
SQLquery = "Select Quan1"etc...;
break;
case 2:
SQLquery = "Select Quan2"etc...;
break;
case 3:
SQLquery = "Select Quan3"etc...;
break;
case 4:
SQLquery = "Select Quan4"etc...;
break;
case 5:
SQLquery = "Select Quan5"etc...;
break;
}
SqlCommand Cmd = new SqlCommand(SQLquery, connection);
SqlDataReader Dr = Cmd.ExecuteReader();
if (Dr.HasRows)
{
gvEstQty.DataBind();
}
Cmd.Dispose();
connection.Close();
connection.Dispose();
}

I need to export SQL query results to an Excel file.
I use the following code to do it.
[Code]....
Works fine for majority of the cases. There is a column called Description in the query results which is of type nText in the sql database. This can have lengthy data ( couple fo paragraphs) . When the number of charcters are large only the first portion of the data is showed and it trims the rare portion. how I can avoid this? Or any efficient code example on how I can do this in a different manner
The query I used here is
SELECT top '"+lblCount.text+"' Company_Id, CompanyName, All_Countries,All_Industries,Employees,Revenue, Status FROM SN001CompanyTable where Client_Id=100 ORDER BY [Company_Id] DESC
but its not showing proper results..
In this lblCount contains the no of row to be displayed..
I'm working on a job seeking website where the job seeker can search for a job , the search box is located in the master page, that's why i passed the keywords as a query string, and then the matching jobs will be displayed in a listview.
the keywords will be taken from two controls: a drop down list which the user can choose the location of the job, and a text box where he can type a keyword.
the select command of the sqlDataSource of the data list is as the following:

I have 2 gridviews on a webpage that are fully editable. I also have a button, that when clicked, runs some SQL in codebehind to insert new rows into a data table. The gridview should then update with the latest results of the SQL query, which is does.
Then the user clicks on to the next page to do the next thing.The problem is, when they go back to the first page, they're still seeing the old, non-updated data. I've run the SQL from the page manually on the server, and the new data is there, but the GridView doesn't want to pull it.
datacontextclass dc=new datacontextclass ();
var news= dc.GetNewsCompany(Int64.Parse ( _idCompany));
if (news.GetEnumerator().MoveNext())
{
foreach (var item in news)
{
drpListNews.Items.Add(item.Title);
}
}
return error:{"The query results cannot be enumerated more than once."}
how can check result != null in LINQ;
The SQL is below - each result is coming up 3 times rather than just once.
SELECT Consignments.LegacyID, TripDate, CollectionName, DeliveryName, Pallets, Weight, BaseRate, Consignments.FuelSurcharge, AdditionalCharges, BaseRate * Quantity AS 'InvoiceValue', Consignments.Customer, InvoiceNumber,
CASE
WHEN child.LegacyID = Consignments.Customer THEN child.LegacyID
WHEN parent.LegacyID = Consignments.Customer THEN parent.LegacyID
ELSE this.LegacyID
END AS 'InvoiceAcc'
FROM SageAccount this
LEFT JOIN SageAccount parent on parent.LegacyID = this.InvoiceAccount
LEFT JOIN SageAccount child on this.LegacyID = child.InvoiceAccount
JOIN Consignments on (Consignments.Customer = this.LegacyID AND this.Customer = 'True')
OR (Consignments.Customer = parent.LegacyID AND parent.Customer = 'True')
OR (Consignments.Customer = child.LegacyID AND child.Customer = 'True')
WHERE (this.LegacyID = @Customer) AND (TripDate BETWEEN @fromdate AND @todate) AND (InvoiceNumber IS NOT NULL)
The SQL was given to me for another similar query, but this time I have modified it to try to use it for the query I'm doing now, so I'm assuming that I'm doing something stupid.
I have a query using LINQ-to-SQL. It queries an underlying database table Rooms. It uses Where conditions to narrow down the results, namely:
Gender.
Current Occupancy < Max Occupancy
Available Flag is Checked
I know this should return results but it keeps returning an empty set. Any ideas? Code is below
Dim selectedHalls = (From sh In dbHalls.Rooms _
Where sh.gender = Session("gender").ToString _
Where sh.max_occupancy > sh.current_occupancy _
Where sh.is_available = 1 _
Select sh.building_name).Distinct()
UPDATE: I've verified that the issue is with the statement where sh.is_available = 1, which doesn't make sense since this is a bit field.
I've managed to use my MS Access database with repeaters and gridviews in my website. Basically, printing the result of a query directly to the website seems easy enough using something like this :
[Code]....
After quite a bit of googling this seems to be a common way to do this. My question then seems kinda silly.
I want to use some of the data from the query in for example a variable without sending the data to a repeater or gridview and so on. Say I just want the username and a password from a database and want to store the username in one variable and the password in another for further use in the code. What do I do?
I can't seem to change the order of the results coming back from a linq to sql query, I want just to return the distinct values from the field x.manufacturer in alphabetical order, this is what I have and it isn't working:
public IQueryable<string> Dropone()
{
return (from x in CAT.CatalogueDatas
where x.Parent == null
orderby x.Manufacturer
select x.Manufacturer).Distinct();
}
Currently I get the distinct values in non-alphabetical order, in fact I'm not sure what order they're coming out in, don't think it's the order in which they appear though.
i query a database for retreiving all the columns. I will probably have many rows. Im trying to output the query results into an html table. This is what i have so far:

How could i store the many rows and output them using html as soon as i open a page?
I have an asp.net intranet site hosted on IIS on my computer.
On one page you can enter two user id's and get a side by side comparison of their roles in our (custom app) system.
I often use it to add roles when I'm setting up new users. After running the query, if i change a role and run the query again it will not show updated results. It's being cached somehow. I have to go to another page and come back and them run the query to get updated results.
How can avoid having to navigate away to get the updated query results displayed.n

I have a Query which I run as an SQL. This is my SQL:
"SELECT COUNT(*) As NoDup FROM [XXX Dir] WHERE (FileName Like 'XXX_YYY_20100916.txt')"
The "XXX Dir" is a table and "FileName" is a text field within that table.
When I execute the SQL in the Query development windows, it returns a single value like 2.
I would like to assign that value to a variable so I can use it in my VB code.
I have a simple Entity query:
[code]....
I then check whether one of the result values is more recent than six months ago using an if..then like so:
If rhcexists.First.SignatureDate > Date.Today.AddMonths(-6) Then
End If
However, if there are no results returned this will return an error. Is there a way for me to tell it to act as if the date is older than six months if there is no value at all? e.g., could I in pseudo do something like:
If Exists(rhcexists.First.SignatureDate, Date.Today.AddMonths(-8)) > Date.Today.AddMonths(-6) Then
End If
I need to concatenate several columns of a table into a single value, then show that value in an asp dropdownlist. The SQL code I'm issuing is as follows:
SELECT UserID, CustomerNum, UserName + ' - ' + UserAddress + ',' + UserCity + ' ' + UserState AS UserInfo
FROM Users
WHERE (CustomerNum = @CustomerNum)
ORDER BY UserName
I then set 'UserInfo' as the text field in the dropdownlist.This generally works, except occasionally one of the columns in the database is null (for example, UserState). When that happens, the entire concatenation is null, and I get an empty entry in the dropdownlist.
Is there something in SQLServer that will allow me to ignore those NULL results, or will I have to code something up in the DataBind event?
I'm using Visual Web Developer 2010 Express. This is my first attempt at creating a .NET page. I have a Gridview on a page that displays the results of a GridQuery. This works. I have a checkbox control(cb_Filter) on the same page that if checked, should add to the where clause of the GridQuery, (where Column5 IS NULL). How do I check the state of the check box so it will run the query with or without the "filter".
View 2 RepliesI'm building a web app for my company that will run a query every few seconds against SQL Server, and the data that it returns is which database is restoring and how much % complete it is. I have the query already set up and it works fine.
What I want to do is on my Web Form, have a "div" element that will contain the % complete of a database restore, and have it update every few seconds using the JavaScript timer object:
setInterval(function, interval)
I figure I would need to use XMLHttpRequest to send the request to the web server which will run the SQL query. Am I on the right track? How would I even start to do this?
My SQL query is below:
Use master
Select der.session_id, der.command, der.status, der.percent_complete, *
