I have a bunch of controls like the following in the EditItemTemplate of a ListView, with LINQDataSource:
[Code]....
I'm curious to know why the database won't update on the click of the Update button:

According to all I've read, the above code should be sufficient. Since CommandName is set to Update, it would seem that no code-behind is necessary.
How to bind "OnDataBound" event of "DropDownList" in declarative syntax to a static method in some other class ?e.g<asp:DropDownList runat="server" id="d1" OnDataBound="SomeOtherClassThanThisPage.StaticMethod"></asp:DropDownList>
This will give the error, "Page does not contain a definition for SomeOtherClassThanThisPage. it like this or it be done in the Code Behind only ?

After trying many solutions listed on the internet I am very confused now. I have a C#/SQL web application for which I am simply trying to bind an ExecuteReader command to a Dropdownlist so the user can select a value. This is a VS2008 project on an XP OS.
How it works is after the user selects a table, I use this selection as an input parameter to a method from my Datamatch.aspx.cs file. Then this Datamatch.aspx.cs file calls a method from my ADONET.cs class file. Finally this method executes a SQL procedure to return the list of columns from that table. (These are all tables in Adventureworks DB). I know that this method returns successfully the list of columns if I execute this SP in SSMS. However, I'm not sure how to tell if it works in VS or not.This should be simple. How can I do this? Here is some of my code. The T-sQL stored proc:
CREATE PROCEDURE [dbo].[getColumnNames]
@TableName VarChar(50) AS
BEGIN
SET NOCOUNT ON;
[code]...
The CreateLabels method above correctly shows me the labels. But the CreateDropDownLists method just shows me one dropdownlist with nothing in it. In other words, it is not selectable. So how can I verify that the datareader is returning all 4 columns and inspect their values? I was able to find from datareader "COLUMN_NAME" but I don't know what properties to search to verify the column names.
I have a page that binds data from DB to a DetailsView.I want to use the auto-generated Update command.
Everything went OK, and also updating was successful, but if I remove any field that I don't want to have chance to update, then the Update command doesn't update! the old values retain!
I mean: if all of the fields are present in the detailsView, the update will be OK, otherwise, the update will NOT update any thing.I've tried to mark the fields that I don't want to view as "Visible = 'false'" but with no good results!
I have a custom page (Page 1) in SharePoint where I have a repeater control. From Page1 I open Page2. This is where I generate a collection of object which i use to bind repeater control in Page1. For the first time everythings work fine. If I have 5 objects to bind, repeater control shows 5 elements.
Now assume, I have 5 elements in page 1. When I open page two It carried over same 5 elements. I delete 1 element and send 4 element as collection to Page 1. In page 1 after I databind the repeater control, it doesn't display correctly. It deletes the wrong element.
I debug my code. The collection which i am binding to repeater shows the correct elements. But while displaying i is not showing correctly.
I have 3 gridviews in one of my web page. I have simplified the system structure in the image below(further description will be stated below the image): As shown in the image above, the web site(presentation layer) will work closely with the Business Logic layer(BLL) and Data Access Layer(DLL). ObjectDataSource control will be the middle man to select, update, insert and delete the data in the gridviews. During Select, returned data from the database at DAL will be stored in a datatable and return to BLL and then the website itself.
The data in the returned datatable will be filetered by type using RowFilter method and stored into the 3 dataviews. Each dataview will act as the datasource for the 3 GridViews respectively, and therefore I specified the datasource programatically instead of setting the datasourceid for each gridview.
dataview1 = New DataView(dtSelectedTable)
dataview1.RowFilter = "Type='1'"
GridView1.DataSource = dataview1
GridView1.DataBind()
dataview2 = New DataView(dtSelectedTable)
dataview2.RowFilter = "Type='2'"
GridView2.DataSource = dataview2
GridView2.DataBind()
dataview3 = New DataView(dtSelectedTable)
dataview3.RowFilter = "Type='3'"
GridView2.DataSource = dataview3
GridView2.DataBind()
However, the Update(command button) and Delete(template field) doesn't work, the RowUpdating and RowDeleting event wasn't trigger when I click on the button, but it works if I set the gridviews' datasourceid to the objectdatasource. I couldn't figure out why, hope that someone who have come across the same problem couldn't provide some guidance.
I have connected listview by using datasourceid that means by using "sqldatasource1" now i want to change value of listview at run time according to search so for that i am using datasource at codebehind. but it give an error
"listview have already bind with datasourceid you can not bind it with datasource"
what should i do for solving my requirement.
I have this code in the page load...For some reason the dropdown binds to the db, but the gridview that I want to bind is not displayed. What could be the reason for this? C#:
SqlConnection conn = new SqlConnection(GetConnectionString());
conn.Open();
SqlCommand cmd = new SqlCommand("SELECT CompanyName, CompanyID FROM Company ORDER BY CompanyName", new SqlConnection(GetConnectionString()));
SqlCommand cmd2 = new SqlCommand("SELECT p.ProjectName AS ProjectName, p.Status FROM Project p, Company c WHERE c.CompanyID = p.CompanyID AND c.CompanyID = 3", new SqlConnection(GetConnectionString()));
cmd.CommandType = CommandType.Text;
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
conn.Close();
company_list.DataSource = ds;
company_list.DataTextField = "CompanyName";
company_list.DataValueField = "CompanyID";
company_list.DataBind();
company_list.Items.Insert(0, "-- Please Select Company --");
cmd2.Connection.Open();
SqlDataAdapter sqlAdapter = new SqlDataAdapter(cmd2);
DataSet ds2 = new DataSet();
sqlAdapter.Fill(ds2);
Gridview1.DataSource = ds2;
Gridview1.DataBind();
cmd2.Connection.Close();
cmd2.Connection.Dispose();

I have a ListView where I am trying to implement Updating. My update parameters are not sent to update command correctly. The value sent is the original value and ignores what I type into the EditItemTemplate. Running a trace on my SQL Server verifies this. In this example, I am only trying to modify [dedamt]. What is wrong?

how would i do my Gridview delete command like a update command?
im using a datasource... and my delete command is like my update command... so i can change the status into "INACTIVE"...
DeleteCommand="UPDATE ACCOUNT_MAINTENANCE SET am_status = 'INACTIVE' WHERE (accmain_no = @accmain_no)"
UpdateCommand="UPDATE [ACCOUNT_MAINTENANCE] SET [account_type] = UPPER(@account_type), [min_deposit] = @min_deposit, [min_capital] = @min_capital WHERE [accmain_no] = @accmain_no"
when i press my delete command at gridview... the status changed into "INACTIVE" but when i refresh or press f5... it automatically update the status into "INACTIVE" also...
I'm using SqlDataSource and at the point of adding a record, I've called SqlDataSource_UploadNewsLetter_Inserting. In here, I'm testing a value, and if it's true, I need to stop the insert from taking place. But how can I stop the database insert at this point?

Girdview has dropdownlist TemplateField called ddlSate, how to bind state field value in sql table to selected value of ddlState dropdownlist control? For example the sql table has AL value for state field, (Note by default ddlState lists all states options with sqldatasource), how AL is selected in ddlState when binding to ddlState?
Secondly, when user selects different state like GA, how below update stored precedure works? that means how to find ddl selected value in update procedure as shown below question mark line:

I have 10 tables in MSSQL I want to select some info from this tables and show on a webpage (formview maybe(based on user selection)). Also, Id like user to be able to EDIT this info, and it should go back to database.
The problem is that: the realtionships are pretty comprehensive. In sql management studio I saw awesome view creation, where u can drag and drop tables and select just the field u need, and it automatically do all joins for you.
View would work perfect for me, but i need to update database back. Maybe I can use linq classes?
I mean, its easy, but it takes a lot of time to do it by hand programatically. Is there some dragandgrop-like feature in visual studio?
what is the easiest way to bind multiple tables in one place with crud operations available?
sql datasource supports only 1 table at a time.
I Found on the web that we can use stored procedure? Do I need two stored procedures? for select and update? how we are going to bind update procedure with textobxes where user is going to edit info? Do you have some samples?
I have a ASP.NET page that contains a formview and ObjectDataSource. On the page I only have 4 fields that are bound to fields in my datasource. My datasource contains 10 fields. When I call an update it is setting the 6 fields I am not binding to to null. The only way I can find it get around this is to add hidden fields for the 6 unbound fields and bind them to the datasource.Is there anyway around this without using hidden fields?
View 1 RepliesHow can I bind radio buttons to an sqldatasource for update ?
View 2 RepliesGridview binding data from database without doing postback on the select of item in dropdown.i know it is possible through ajax update panel but for some specific reason it can't use it.And i think that gridview is a server-side control and if i implement it by using table structure , jquery ajax and web service then it will loose all gridview properties of edit, update and paging etc.
View 1 RepliesI have one repeater control in my web page.
And i want to bind this repeater control from button.
But button is in Update panel in ajax.
And repeater control is outside the updatePanel...
Code Example:
$(document).ready(function() {
txtchangefunction();
});
function txtchangefunction(
$(".textCssClass").change(function () {

or $(".textCssClass").bind('change', function())
both work for Chrome etc. but not IE8. no console error comes out.

ser1,... NOT ==> ser1, , , ...

I created 3 category table. categry1,categry2,categry3. product table.
And then use of gried view add ,edit ,update ,delete product . in product table.
In gridview retrive data from product table . i select categry from dropdownlist in gridview categry1, categry2, categry3 and save update dropdown list category value dynamically in product table. not define value static in source code.
When select category 1 change on selected index change categary 2 or 3.
In my code I used text box to ediit update delete. but here i will use dropdownlist.
I've recently started working in ASP.NET and RDBMS.I'm making a test form where I can do basic add,update,delete operations.I'm using OracleDataClient to do the DB operations.I was able to populate a listbox using OracleDataAdapter.
Now after clicking on update button,I intend to Update in DB.I've Dataadapter with it's update property.But the update query is not happening.The examples I saw over net all have Select command before Update.Is it actually like that or am I missing some point.
How does Oracle DataClient work with Insert,Update,Delete Commands.
