I have some textboxes and radio buttons in my form, and when the user clicks the "Search" button, an SQL select query is run from an SQLDataSource and that query populates a gridview. I want some of the values in these textboxes/radiobuttons to act as search criteria and I'll form a WHERE clause based on what the user typed into them. How do I do this?
View 8 RepliesI'm using parameterized sql query to get data from database
string query = "Select * from employee where employee_city in (@value)";
strign city ="'NewDelhi','Bangalore','Mumbai'";
I'm using following code to achive this
[code]...
But this is not giving the result. If run the query in SQLServer query window as "Select * from employee where employee_city in ('NewDelhi','Bangalore','Mumbai')", records are there.
But the same query will not return any records from ADO.Net.
I have a repeater which is binded using a Collection of Entity Data Framework.
Once the repeater is binded using the datasource, the user can control the no of rows present in the repeater using a Dropdown list on the page. For ex: if datasource has 2 rows, user want to add 3 more rows, user selects 5 from dropdown, which adds 3 additional rows to the Repeater. I am able to do this.
The repeater has textbox controls in each row. Now once the user enter the values in this textbox of the newly generated rows, the user can save the values entered with the no of rows specified.
I have a button which is outside the repeater and on click of this i need to validate all the textbox values and save them into dB accordingly.
Here is my code
Repeater.aspx
[Code]....
[Code]....
Repeater.aspx.cs
[Code]....
Right now the problem is im not able to fetch the values of the textboxes present in the newly generated rows.
[URL]
openDB() Dim inList As String Dim getCourses
For k As Integer = 0 To arLcID.Count - 1
If k > 0 Then inList &= ","
End If inList = arLcID(k).ToString
getCourses = "select cID,cCode,cUnit from [university].[Courses_1] where cID ='" & inList & "'"
insertCMD = New Data.SqlClient.SqlCommand

This code is not returning any value, when the arraylist is removed it returns value.
I know I'm missing something here but I can't figure out what it is. I've got a query joining three tables....accounts, payments, and a table linking the two (there is a M:M relationship).I'm trying to pull a list of all accounts in the account table that have a payment that needs to be resequenced, and also the maximum payment priority if there are any payments that haven't been fully paid. If all payments HAVE been fully paid, I want to return a 0.
It's that last bit of logic that I can't get right. If I include that in the where clause, I get only the accounts that have a payment that hasn't been fully paid. If I take it out, I get all the accounts I get, but I get the highest payment priority whether or not the payment has been fully met.
Here is the query....how do I include the where clause criteria but still include all accounts?
select distinct
bat.acct_id,
isnull(max(isnull(crt.pymt_priority, 0)), 0)[code].....
I have a page of several textboxes, which I would essentially like to populate from a single query. However, to begin with, I find myself unable to even populate one textbox from one query!
I have based the following on a query previously advised to me for use with drop-down lists (hence the use of DataTable). I have adapted this as follows:
AddData.aspx:
<asp:TextBox ID="tbNewDataNum" runat="server"></asp:TextBox>
AddData.aspx.vb:
Partial Public Class AddData
Inherits System.Web.UI.Page
Dim CommonFunctions As New CommonFunctions
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
[Code]....
I would like the Page_Load event to populate the textbox with this query, so that the value is present as soon as the page is presented. Also, how would you advise populating many different textboxes in one go, with one query? Is this possible too?
add the numeric values in two textboxes(textbox1+textbox2)
and when the button event takes place
the value(textbox1+textbox2) has to be displayed in textbox3.
can some in send me the code'for that .
i tried to convert string to int
but its trowing some kind of errror
Is it possible to add values in textboxes as well as subtract values? Scenario:
txtbox1 value = 3
txtbox2 value = 2
txtbox3 value = txtbox - txtbox2
I have able to generate several labels and textboxes based on a table in the database during runtime. My problem is that I could not get these values from these textboxes whenever a user changes these values and update them.
View 4 RepliesI am using this code which works perfect when I type username and the studentid in my textboxes in the first page.Now after pressing the button to go to the second page , the two labels display the values of the textboxes in the first page BUT when I am pressing a button in my second page I get this error :
Object reference not set to an instance of an object.
My code which is in the second page load event is :
Label1.Text = "Name:" + CType(PreviousPage.FindControl("txtusername"), TextBox).Text
Label2.Text = "Student ID:" + CType(PreviousPage.FindControl("txtstudentid"), TextBox).Text
Is there any option to make this labels keep their values ??
i have the following code. i am dynamically generating some textboxes, and i need to retrieve the values of those boxes at the click of a button in order to save to a Database...

I have a textbox and the date needs to be in between two dates. I want a popup message to display when they are out of those parameters. I don't want to use the Validator's because they make you put in a date to move forward.
One option is if I do use them is it anyway to add "out of date parameters" when they don't meet those dates then move to the next question?
Another option would be to just check the date, give an error message and move to the next question. Is it possible to do either one of these?
See I want the values from my database to be displayed in textboxes by stored procedure.
I am having knowledge of inserting values to database by using stored procedure.
For Ex: database fields are
1) Studentid
2) Student name
From user i am accepting Student id in 1st textbox.
when user click ok on the button then he would be having
Student name in next textbox by using Stored Procedure..
Language I am using is C# & internal sql database
I have a form where one field needs to check if the person is up to 17 years of age by between 01/01/2011 and 12/31/2011.
So I added a a Range Validator and Validator Callout Extender
How can I get the page to check this range when the user enters in their dob in the dob textbox then when they go and enter a date in the bmidte box (if they are over 17 years of age) I want my error message to apper.
Here's the aspx page code:
RangeValidatorBMIDte.MinimumValue = "01/01/2011"
RangeValidatorBMIDte.MaximumValue = "12/31/2011"
RangeValidatorBMIDte.ErrorMessage = "Date Entered is NOT Valid. Value needs to be between 01/01/2011 and 12/31/2011."
12/31.

I'm having trouble writing what should be a simple sub-query using LINQ to Entities. I have two tables: Customers and Orders that have a relation on the CustID field. Not all Customers have a record in the Orders table, while some have mutiple records. In traditional SQL, you could write the query like this: SELECT * FROM Orders where CustID IN (SELECT CustID FROM Customers) I know this could be done as a JOIN in both SQL and L2E, but my actual query is more complex (about 8-9 joins), so I am hoping to find a L2E sub-query equivalent. Something like this:

I know LINQ to Entities does not support the " IN " clause, so I am looking for something that will work in its place.

I have Grid view control in the page. Enable paging option is true.
Columns in the Grid view are ID, Name, Checked and Email
Whenever user selects the check box then I am showing txtEmail in the Email columns so that I can enter email id in the textbox.
Like this I am selecting checkboxes and entering values in the txtEmail when I go to next page and comes back. Then these entered values are cleared.
How to keep the textboxes values and checkboxes selected during paging?
I have been doing R&D for 1 day. Tried to implement.
how do I do the most simplest thing like get the values from textboxes in a form and bind them to my lets say product or whatever object?
I work with MVC 2 and NHibernate. I seen some examples where they work with linq 2 sql and what they do is just save the product in the controller like _repository.Save(product);
they use active record and is that why that is possible? And in this example they use on the beginform like this
