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.

View 7 Replieswhat the problem is that i want to populate drop down list manually
but the thing is i have 3 drop down lists
in first one user will select table name from where the data of 2nd Drop Down list will come
suppose user selected seo then the sql query would be select project_name from dropdownlist1.selecteditem
and this query will show project_name column of seo table in dropdownlist2
then user will select any project name from dropdownlist2 suppose he select salveo so i want that my text box will get populate with project_id of project_name
suppose the project_id of salveo is 123 then automatically in textbox it will enter 123
I aggressively googled around, but could not find the information I am looking for. I know how to populate a dropdownlist using my view model andHtml.DropDownListFor helper method.
Suppose the drop down list contains U.S. stateId and stateName key value pairs. Suppose my ViewModel looks like
public class MyViewModel
{
public IList<State> States {get; set;}
public int SelectedStateId {get; set; }

Do I have to change my implementation of my view model? In any case, how to get the selected item text of the drop down list?

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 dropdown control that has a list of names in it called PlayerNameDropDownList_Insert and a textBox called PlayerName.

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.
View 1 RepliesUsing C# and SQL as the database.I have a page with a gridview and some text boxes and drop down list boxes. A user selects a record from the grid view I query the database and fill the text boxes and drop down list boxes.
Some fields get updated periodincally thus there is no data in those fields in the database until some time.
A strange thing happens.When filling data some text boxes gets a one tab spacing .
I have a GridView that displays records from an Access database, and I want to filter the records using a selection from a drop-down list. The GridView populates on page load with all of the records. The drop-down list is populated at page load from a different table in the same database. The functionality of creating a new GridView filtered by the selection in the drop-down list is working. However, when a different page number is selected from the Pager of the GridView, the GridView "disappears," or isn't redrawn. The selected name remains selected in the drop-down list, but there are no GridView elements displayed. If I select another item in the drop-down list, I get a new GridView with the correct records, but then choosing a different page results in no GridView. I'm guessing there's something wrong with my OnPageIndexChanging for the GridView event code, but I'm not sure what. My code is below (C#, ASP.NET 2.0):
using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

on my aspx I have the below DDL
<asp:DropDownList ID="ColorDDL" runat="server" DataSourceID="ColorObj"
DataTextField="Size" DataValueField="BustId" Width="150px"
AppendDataBoundItems="True">
<asp:ListItem Value="-1">(Optional)</asp:ListItem>
</asp:DropDownList>
If the user does not select an item I get an exception when i call the ObjectDataSource Method and DAL as below to insert into database
ProfileObj.InsertParameters["ColorId"].DefaultValue = ColorDDL.SelectedValue.ToString();
What I want to do is insert a database NULL instead.
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.

View 2 RepliesWhat I am looking to do is have a page with 2 seperate datagrids on, I want to be able to add the selected rows from DataGrid1 into DataGrid 2 either with a button click or using drag and drop functionality (Im guessing this would require javascript and I have no experience with this language, is it difficult to learn or could I just alter code from elsewhere?). Once the row is added into DataGrid2 I would like to be able to add some information, such as Quantity and DateDue (could this be added in a pop up box when the part is added?) Also I would like fields in DataGrid1 to be based upon a search with several different options that the user specifies, i.e the ability to search based on project number, however it would return eitheer parts or assemblies depending on a check box selected. I have very limited programming knowledge but Im guessing I would be able produce a query based on the inputs, but in order for this to work wouldnt the page to postback everytime an option was changed.
View 1 RepliesI have just built a contact form for a website and it works fine but now I would like the "Subject" textbox to be filled if the user has been redirected to the contact.aspx page from another link.
For example if the user just clicks on the contact us link then the form will be blank but I have some items on the website where there is a link that says "Enquire..." that redirects to the contact.aspx page but I would like the subject textbox to be filled in with the item that it was redirected from?
