Is it possible to bind two separated datasources to one dropdown list such that they are both alphabetically sorted and seprated by some sort of line. I know there is a way to insert elemets manually, but I'm not sure of the 2 separate datasources. I've serached this forum and while there were several posts none of them offered any workable solution.
View 5 RepliesI have a formview in which I have a dropdown list that displays a list of owners. In case the list does not have the correct owner for the user I have added functionality for them to add a new owner to the database table that populates the list. I did this by including a textbox and an Insert button in a panel. When the user clicks the new owner insert button I would like to re-databind the dropdown list so that they will see the owner they added and be able to select it.
When I add ddl_owners.databind to my button click code it gives me an error. "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."
I don't want to re-databind the entire formview because then it deletes all the information on the form that the user has already keyed in.
I have "Testdtabse" it's consists of the Table like aaa,bbb,ccc,ddd,eee etc.. I want to bind that table names in to My droipdown list box..

View 4 RepliesI have created an asp.net customizable gridview where user will be able to add and delete data. Now I face some proplem with this gridview. now I want to add a dropdown list (which is dynamically bind with database) inside the grid. I created code and it bind well. when the page is post back previous selected dropdown list value lose and set to selectedIndex=0; For this reason I used if(!page.Ispostback) and put the dropdown binding code inside this. Here I faced a problem. The problem is when I want to add data inside grid the dropdownlist missin bind. How can I overcome this problem? For your kind observation I given entire code below:

I am attempting to bind data from a dropdown list that was populated from another datasourceID. I've bolded what I believe is relevant to this issue in the code below. But basicly its binding the proper county on the pull down menu but when I hit form submit it dosnt postback that info instead its null.
[code]....
I have two AccessDataSources each returning one row.
I want to use the data in each row to populate content on my page, so I figured I would use a [Code].... or [Code].....
However, I would not necessarily want the labels bound to a particular DataSource placed together.
For example, I might want labels from the following columns in order [Code]....
:
[Code]....
Note: No language preference (C#/VB).
I am stuck at this point "Displaying a dropdown list of Categories with a --None -- Option. I want the gridview control to display 2 dropdown list one in read-only mode and the other in edit mode. When a record is in read-only mode, the dropdownlist's enabled property will be set to false."When it's on a read-only mode, it doesn't display the selected Category. it shows but the "No Category". When i click on edit to edit or change category, it doesn't display the selected category.

I have a BLL where in I am getting all the data from a table. Now I want to populate a dropdown with one of the field in this BLL.
ddlstatus1.SelectedValue = dt.Rows(0).Item("StatusCode") and this is not working.
I tried ddlstatus1.SelectedIndex = dt.Rows(0).Item("StatusCode") too but this is throwing an error that string cannot be converted to Integer.
I've a dropdown list for selecting countries. As there are lot of countries it's very tedious to add each country like this
drpdwncountry.Items.Add("India");
drpdwncountry.Items.Add("USA");
drpdwncountry.Items.Add("Russia"); etc
is there any other way to add list of countries ?
I have a situation where I want to show the selected records out of total records for a product of an employee
1) There is a checkbox list bind to <List> of objects from object datasource (For total items in list)
2) Now I want to check the selected items for a particular record in this list
3) For this purpose I have another list of <List> selected items returned by data access layer (For selected items for that employee )
4) How do I bind the selected objects with the total items list ?
5) In spaghetti coding model it was all too easy just by binding the checkbox list with a sql data source and running a for each on form load
I have a databound dropdownlist and have a problem with the default value it selects.When I attempt to edit a record the dropdownlist shows the first value in the list rather than the current value. I want the dropdown list to display the current value.
I'm sure this is very simple but I'm very new to ASP.NET.
I'm using .NET version 4.
I would like someone to explain how I can pass a drop down list from the presentation layer to the controller using the Model View Controller Design Pattern from Microsoft in order to bind enum values to it?
View 2 RepliesIn vs2008 and sql2005, I want to edit gridview..
In edit template I want a dropdownlist that must show that row's cell's value as the first value and remaing values should come down in the dropdown.
I have a GridView contain ClientID, ClientName, CompanyID columns.
1. I want to display CompanyName by Company ID
2. In Edit Mode I want to show company Names in DropDown and by chaging dropdown Bind the value. I am displaying DropDown data with a separete datasource.
I have been facing this problem for a while now, what I exactly want to do is ->
I have a 3- Tier Application. For a table (say Employee) I have following classes in my BLL and DAL
1. Employee.cs (Contains database fields as properties)
2. EmployeeKeys.cs
3. EmployeeFactory.cs (Main BLL which make call to DAL method)
4. EmployeeDAL.cs (The DAL)
Suppose I have 6 columns in Employee table.
I know that the DAL returns List<Employee> to the BLL and then the BLL in turn gives me the Employee fields.
I have no problem accesing it.
But suppose I have a dropdownlist control and wish to bind EmplyeeName and EmployeeId with the Dropdown.
Is there any way that I can implement that my DAL returns a Generic list containing only the two fields required to bind the Dropdown.
In short i want my list to return only 2 columns, not all the 6 like the List<Employee>
How do i implement this???
Do I need to create a custom List<CustomEmployeeData>, if so how can i implement it in the 3 tier application.
Basically i m looking to increase the efficiency by getting less data from database. Am i on the right track????
I have a dropdown list with hard coded values:
<asp:ListItem Text="One Day Shoots" Value="1" />
<asp:ListItem Text="Multi-day Shoots" Value="2" />
I want to use this to insert and edit values from a db. For example when adding a record the user selects 'One Day Shoots' and 1 gets inserted into the database. Then if the user goes to edit the page since the value in the db is 1 then the 'One Day Shoots' is selected.
One way I considered accomplishing this was by using a hidden feild - when the user selects something in the dropdown list the field is updated with the value, then when the user actually adds the record the value in the feild is submitted. I'm pretty sure this would work but is there a better way?
I have the following structure 3 Dropdown Boxes, the 2nd and 3rd dependant on the 1st and when I change the first combo the pages refreshes with error I am assuming it's happening when posting back. I have nothing in my code behind file for this page so far.
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
This is a very Basic application that I am creating using Visual Basic and ASP.Net 3.5. Am using a SQL Datasource have searched for this error some of the answers seem extremely complex and I can't figure them out, surely a simple tasks like this has to be easy to bind back to the database from several drop down lists.
I have one grid in which i use one datasource to get several data . Now i want to ad a column in my grid and bind that column with a column from another datasource.
