View 1 RepliesI'm trying to implement live binding, purely imperatively . In my example , I have a master view , which is populated using json array. In the detail view ,I'm just setting the value of a prepopulated combo box . But , the moment the bind statement is executed, the combobox (select element) becomes null. This works perfectly when done declaratively. Below is the code for imperative binding. This function is triggered when an item in the masterview is selected.
function execCommand(sender, args) {
// Create dataview for details section
var detailsView = $create(Sys.UI.DataView, null, null, null, $get("div2"));
$get("div2").className = "sys-template";
// bind the dataview to the selected data from the master
var b = Sys.bind(detailsView, "data", sender, "selectedData");
// after the above line of code is executed, the select element with id "myselect" becomes null.
//alert($get("myselect"));
// bind the value attribute of the combo box to the "Description" property of the binded data
var x = Sys.bind($get("myselect"), "sys:value", detailsView.get_data(), "Description");
//hence when the above line of code is executed , nothing happens :( ,i.e the value of the combo box doesn't get set
// alert($get("myselect"));
}

The drop down list is used to determine what search criteria will be used to find an invoice. I tried to set the Select method in the switch statement. I don't understand how to set the Select Method and the select parameters programmatically though . I tried a few different ways but can't make the compiler happy. My ODS is in scope in the code behind. I'm not able to access it's properties though. The BAL resides in a separate project that is a ClassLibrary. I also have a using statement for the ClassLibrary project in the code behind.
give me an example of how to do this?
Mark up:

protected void Button19_Click(object sender, EventArgs e)
{
SqlDataSource conn = new SqlDataSource();
conn.ConnectionString = ConfigurationManager.ConnectionStrings["Database2ConnectionString1"].ToString();
conn.SelectCommandType = SqlDataSourceCommandType.Text;
conn.SelectCommand = "SELECT FROM table1 (a, b)VALUES(@a,@b)";
conn.SelectParameters.Add("a",TextBox1.Text);
conn.SelectParameters.Add("b", TextBox2.Text);
int rowsAffected = 0;
try
{
rowsAffected = conn.Selectt();
}
catch (Exception)
{
Label1.Text = "Error";
}
finally {
conn = null;
}
if (rowsAffected != 0)
{
Label1.Text = "Data saved";
}
}
well it returns error no overloading method for select (P.S. same code work fine for insert)
Can any one let me know about the below issue. I have a page which has three labels, say startdate,enddate and username. My issue is if the user doesnot select any of the above three then a message gets displayed as "Please select one search criteria" or if the user doesnot enter the date in correct format then i dispaly "Please enter date in mm/dd/yy" format. But what is happening is first time if the user doesnot select any then "Please select one search criteria" is getting displayed and after this message gets displayed if the user enters wrong format of date then both the messages are displayed.
View 5 RepliesI will declarate a attribute, but it gives me an error
This query works fine and returns 1 record from type int:
SELECT TOP 1 DataObjectVersionID
FROM tblDataObjectVersionPropertyValueText
WHERE PropValue like CAST('00010281' AS ntext)
ORDER BY DataObjectVersionID DESC
And when I will declarate a attribute/parameter it gives me an error:
DECLARE @dataObjectVersionId INT
SET @dataObjectVersionId = SELECT TOP 1 DataObjectVersionID
FROM tblDataObjectVersionPropertyValueText
WHERE PropValue like CAST('00010281' AS ntext)
ORDER BY DataObjectVersionID DESC

View 6 RepliesI have gridview. some columns are data, and some are link buttons. now, I need move these link buttons to a hovermenu. this is done. but I got a javascript exception, and it is because if there is no row was selected in gridview, it will pop this.
so, the question is: how can I select a row in gridview without select command? simply by code?
Is there any way to do this? I can't find anything to latch on to.

View 8 RepliesI am trying to write a stored procedure that takes out a list of blog entries from a table (tblFeedEntry) as well as the amount of comments that each blog entry has gotten (tblFeedComments) but all I can get is the total amount of comments of all blog entries together, displayed on all entries. This is how my code looks today:
[Code]....
I am guessing that the problem is that the declared variable is not picking up the id of the blog entries, instead it picks up everything. The original select and the select in the declared variable are not connected. How do I connect them?

View 2 RepliesI am moving to the world of ASP.NET from an Access VBA / VB6 background and having read a few books on the subject I am still confused about communicating with SQL server in VB with ASP.NET.
As a very quick explination I am used to communicating with the server by passing strings containing the data I want to write (or read) such as:
[Code]....
I do not seem to be able to work out from ALAX, Dynamic Data, Bound Controls, DataViews, connecting to services with SOAP, DataSources and all of the other methods of database communication in ASP.NET which is the right system to do the simple reads and writes in SQL that I want to do.
At present I have a page with all of the controls on it required to collect a block of data I want to insert, it is all now fully validated but although I can build the SQL INSERT command in a string I cannot figure out how to fire it over to the local SQL Express server. Am I even doing this correctly or do I need to look at other controls?

View 5 RepliesI have a piece of code which loads either french or english text and 2 link buttons that allow to switch between.
[code]....
What would be an efficient way of displaying the link buttons and text if both English and French exist and the session exists in either EN or FR.
I've thought of using panels to hide the buttons or text, but the main problem is having the page refresh to set the Session variable. Response.redirect(URL) to refresh the page i suppose and i can't find a better way to display the text other than to Response.write it since then i'd need a ton of labels.
