Web Forms :: Selecting A Value In A Drop Down Box And Then Populating 2 Fields Based On Value
Feb 11, 2010
What is the best way to do the above? Basically i have a drop down list box with a list of names pulled from a database. When someone selects a name i would then like to populate two further boxes with the persons Login ID and Email address which are held on the same DB. I have currently been using Combox1_selected index change and then running a select query on the database to fill in the other fields - unfortuntly this is too slow. There must be a better way then this? I will also need to put the values in a DB in a later stage so will need to be able to retrieve these values.
As an infopath developer this can be done easily on InfoPath using a filter - is there anything similar in ASP.net

I have a Grid view which is being populated from a database. Now I want to add a button that has its own html with some Hidden fields. I have introduced an Template Field and put the html in that field which works fine. But now I want to send the values in hidden field dynamically. i.e. the Id and value comming form the database.

I'm not sure if I can explain this properly, I just need some advise. I'm working with a formview and datasets to populate the information. However I have a table specifiying which fields to display. In my table If cell, work and home fields are selected then those fields must be populated in the formview if they not selected then it shouldn't be shown. These are 2 different datasets being pulled into the formview.
Right now I have a datasource populating the formview via the wizard, not sure what to do next.

I need to populate the data in the text box according to the values selected in the drop downs.
If the text box is empty it should show a pop up on hitting the save button.
We are using DTO (Data Transfer Object) to populate the data in the drop down and also text box.

I have a drop down box with values that shows on loadUnited States Canada Now I have a function that is checking the users value from the database which is fired on a button click. What I plan on doing is comparing the string like if United States(db value) == United States (dropdown value) then go ahead and select United States in the drop down. When I do this I am getting the right value selected but it is making all the values the same for all records.

I have 3 drop down boxes, created using the HTML select tag. On page load, the first box has a few names. Now, when I click on one of the names in the first box, some more names should appear in the second and when I click on a name in the second box, some more names should appear in the third box. How can I achieve this using AJAX? I have to use ASP.Net and MS SQL Server only. I'm a complete noob to AJAX and I've been educating myself about it, but nothing's working out. I've been looking for the code for close to a week. I looked up w3schools.com, but when I tried that code, it didn't work. Please help me out and please tell me step by step, the things required in order to make it work, and what goes where. I have a deadline that is fast approaching and am at my wit's end trying to make it work.

I have three dropdowns that are used to choose a date (day, month and year). I want them to initially display today's date. They are being populated with code like this:
[Code]....
So the user changes the value to whatever they want and hits the Submit button and I try to collect the values they have chosen...
Code:
DateTime returnDate = new DateTime(Convert.ToInt32(myRYear.SelectedValue), Convert.ToInt32(myRMonth.SelectedValue), Convert.ToInt32(myRDate.SelectedValue));
But the #@#$!@# thing returns today's date!
This is not what I want obviously. Can anyone tell me where I'm going wrong? Why doesn't it return the date as chosen?
If I remove the myRDate.SelectedIndex = DateTime.Now.Day line from the initial population statement the 3 dropdowns are set to 1/1/2010 but the chosen values are passed to the database correctly.
Is there another way to set the initial selection that will not affect the dropdown for all time.

I have a stored procedure named spGetCustomerByCustID that returns all of the fields for a customer whose CustID matches the parameter. I'm using this to populate a drop down with the last names of the customers.
I want the drop down list to be populated with a concatenation of the LastName and the FirstName in that order with a comma and space separating them. So it would be like "Smith, John". It should be easy since my procedure is returning both values. I don't understand how to do this though. I'm not sure if it should be done with the DataTextField or the SelectedValue.
this is the ddl now:
[Code]....

I am re-writing Access applications to ASP.net using VB. On one Access application I have a combo box that is capable of displaying an entire record (3 fields) from a table on each row of the combo box. When that record on the combo box is selected, each of these 3 fields updates 3 separate fields on another table. This is an easy process to do in Access, but I cannot seem to find a way to do this in ASP.net using the drop down list. Can a drop down list display multiple fields or an entire record or is the drop down list limited to a single field per row?

I have a form that has a MAC Address field and a Password field and I have the chrome auto-fill options turned off, but when I load the page, chrome thinks the MAC Address should be an e-mail address and puts an e-mail address in there and for the password, it puts a password in there. Is there a way to prevent this behavior? Is there way to do this programmatically on page load, I tried clearing the fields, but that doesn't work.

I am new to Ajax in general but I have a series of cascading drop down lists that are working fine. I'm using them on a form that I want to be able to either add a new row of data to the database or edit an existing one. I have the insert a new row working but editing an existing one is a bit trickier. The drop down lists are only part of the form but I would like to be able to query for a row id and set their values. Right now I'm querying for a row of data and populating the form with its values on page load and all of the fields work except for the drop down lists. I assume that this is because when the page is loading the web methods haven't run yet to populate the cascading drop downs. Therefore I can't set the selected value because there aren't any values yet. So therefore I'm pretty sure I need to do this from a web method so that it runs after the lists are populated or while the lists are populating but I don't know how.

I am trying to set the item that is selected from a drop down list based on what it in the database for that particular record. I am filling the dropdown list with a SQL DataSource I have tried a couple of example that I have found for selecting the item in the list but I am always getting the first item in the list as the selected item. This is what I am currently working with:
Code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If IsPostBack Then
Else
Dim ID = New Guid(Request.QueryString("ID"))
[code].....

In my controller I generated a SelectList that I pass to the dropdown helper:<%= Html.DropDownList("abc123", Model.SomeList) %>I look at the querystring for a value, which is a ID.I then loop through all the items in the SelectList and if it is equal to the ID, I do:The controller action then passes this SelectList to the view and then to the Html helper.In debug mode I can see the value does get set to true, but the html renders without selecting the item.

I have a gridview that is populating from a SQL DB and working fine. However, based upon certain data I find in fields in the SQL table, I want to place a 'n' or a 'y' in extra columns in the gridview that I am assuming need to be templatefields. My thought was I could maybe add 8 template columns and then I could put a 'y' in the appropriate column based upon the data I find the table. For the life of me, I cannot figure out how to do this. I want to do this at rowdatabound time ( i think) but I just cannot find out how to, in my code, put that 'y' in the columns. Is this the right way to do this or do I need to do it another way? How do I get that 'y' in the proper column?

Just wondering the best way to do something. I want to fill up fields on a website based on a selection from a list. For example, the user selects "Melbourne" from a list of Australian capital cities and the page will fill up with information from the database relating to Melbourne.

I'll admit that I'm not the best at SQL, but what I have is a database that has different podcasts in it. We have 3 locations, so each podcast contains three columns, one for each location. In each column is the date it was shown at each location, or null if it wasn't shown there. Most of the time, I'm selecting podcasts for a specific location, which is easy enough:
[Code]....
But what if I want to select them all? I want "Date" to always be the Hudson location, but if Hudson is null, I want it to be the date of the location it was shown at: AuroraDate or StowDate.

I am creating an application with html using vb as the back end. Microsoft Visual Studio is the application I am using.
My question: I have two drop down boxes...one called department, the other program. When a department is selected, I want the program dropdown to only display the programs that are associated with the department chosen. I have found several different codes to do this but nothing has worked so far.

I want to limit the selecting of data records to only the user who created the record, OR a users who's email address belongs to the domain of the record being edited. So, if the producer has a value in the URL of "[URL]" and their email address in the Membership is [URL] they will be able to see the record.
I have the following table:
Table - Producer
Field: ProducerID
Field: ItemUserID
Field: URL
I have figured out how to select based on the ItemUserID (see code below), but I don't know how to compair the email address values of URL and the Membership.
protected void SqlDataSource1_Selecting(object sender, SqlDataSourceSelectingEventArgs e)
{
if (Page.User.Identity.IsAuthenticated)
{
//get id of user logged in
e.Command.Parameters["@ItemUserID"].Value = Membership.GetUser().ProviderUserKey;
}
}
how to code my requirements?

I am a complete newcomer to ASP.NET. However in the few weeks I have been playing with it I have got pretty far and have mastered things like stored procedures, gridviews, formviews and templates.I have a dropdown box which is populated from SQLDataSource1
I have a second dropdown box which is populated from SQLDataSource2, but i need the query feeding this to be dependent on what was selected in the first dropdown box. I assumed it would simply be a case of modifying the select statement on SQLDataSource2 using the SelectedIndexChanged event on the first DropDownList to update the second SQL source, but I cannot work out for the life of me how to do it. Pretty much all of the code I have is ASP.
can i do this purely in ASP rather than using VB behind the scenes or do I need to use VB? I am pretty comfortable with vb.net but one of the other issues I have is referencing an ASP object from VB... so for instance if I had a text box in ASP, how can I read or change the properties of this object from VB?
FYI I am using Visual Studio 2010 and SQL/Server
