Web Forms :: RadioButtonList SelectedValue From Database?
Oct 18, 2010
I've two RadioButtonLists which pulls "fullName" and displays, the idea is for the user to select from RadioButtonList1 and RadioButtonList2 then submit the data.
If there is already values assigned from sql then there should be a selectedvalue for both controls. But I can't seem to get the controls to assign the selectedvalues.
I've a SqlDataSource, 2 RadioButtonLists and some code binding it:
[Code]....
Also when I go to select just one record from RadioButtonList and submit the data, it returns errors because it sees it as submitting null values.

I have a FormView with an EditItemTemplate. In the EditItemTemplate I have a RadioButtonList. I want to populate the selected button from the database. My code looks like this (simplified):
[Code]....
The stored procedure usp_GetOrderDetails returns a char(1) column called "side" which can have values of 'B' or 'S'. If it's a B or an S I want to select the correct item in the RadioButtonList, radSide. Is this possible? I've done it for my Text boxes and dropDownLists on the same form OK, I just can't figure out the RadioButtonList.

I have Gridview inside that i have RadioButtonList,Which is working perfectly. It also bind correctly.
Problem is when user navigate page,the value which was slected in previous page is not apper again.
Gridview is enabled with paging.
I want to save data on SUBMIT button which is outside gridview. So when user clicks this button it should get ALL selectedvalue of radiobuttonlist inside gridview INCLUDING paging and save it to database.
I have tried following code on Button_Click but its not working properly.

It is working fine in InsertItemTemplate, but in EditItemTemplate i am getting this error "'branchDDL' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value".
. Following is the code:
<asp:TemplateField

I am using:

This solution doesn't work though. It doesn't leave the option of choosing anything from the list. Plus I would like it if it were a Radiobutton instead of a Dropdown. The field in the database is varchar(50).

I have a form which has some dropdownlists (ListItems "Yes" "No"). I use my form to Enter data & submit to database and use same form to Edit aswell. Like I redirect to this form from another page with a QueryString. If there is a QueryString then SELECT * FROM Table WHERE ID = QueryString's value & fill all the controls in the form like
[URL]
I have certain things to do when DropDownList.SelectedValue = "Yes" so I can use SelectedIndexChanged event handler & AutoPostBack="true" when submitting form for the first time. Now when I edit the information(Data filled from table as stated above). How can i automatically fire all events like DropDownlist SelectedIndexChanged in the page_Load iteslef so that all the things that are supposed to be done when DropDownList.SelectedValue = "Yes". I'm posting my test code for reference to explain what I'm trying to do. This is just the Idea. I have something else to deal with if i can get this stright. I need to dynamically add controls based on the values of DropDownList. please suggest some thing guys.

New to asp. I'm trying to figure out how to populate a radiobuttonlist with selections from a table in a database. I honestly have absolutely no idea how to do. There will be different products in the database that need to be pulled to different radiobutton lists.

I have a form for our staff to list an event in a calendar system. In the form, there is a DDL for their Department, and a CasscadingDropDown that provides a list of staff members (the staff list is filtered by Department, as chosen in the first DDL). When the form gets submitted, I need to store the selected values of both DDL's (DepartmentID and StaffID, respectively) into the database.
So, I have a DetailsView, and am using the InsertItemTemplate. Now, I can get both DDL's populated correctly (with the cascade working correctly), and I used custom DDL's derived from the standard DDL class to avoid any Postback/EventValidation problems. But I can't seem to get the values of the user's selected items so I can save them back into the database! I've tried many different approaches, but all I seem to get returned is a value of "".
Here's what I have so far...

I have a WebForms page that has two DropDownList controls on it that both contain a range of temperatures from 60-80 degrees, one for heating the other for cooling. They are declared in the .aspx as:
<asp:DropDownList ID="heating" runat="server" />
<asp:DropDownList ID="cooling" runat="server" />
The values for each list are populated in the code-behind using:
for(int i = 60; i <= 80; i++)
{
var listItem = new ListItem(i + " degrees", i.ToString());
heating.Items.Add(listItem);
cooling.Items.Add(listItem);
}
When I try to set the selected value for each DropDownList using the values in an object containing data loaded from the database using:heating.SelectedValue = myHome.avgHeatingTemp.ToString();
cooling.SelectedValue = myHome.avgCoolingTemp.ToString();
The SelectedValue for both lists is set first to the value in myHome.avgHeatingTemp, then to the value in myHome.avgCoolingTemp. Heres what the values are for each variable after each step of the process of setting the SelectedValues:
Initial State
heating.SelectedValue: 60
cooling.SelectedValue: 60 [code]....

I have a ASP.Net webform with a DropDownList control. This Dropdown gets it's values from a states table in an ObjectDatasource. The Dropdown contains states spelled out.
If I try to set the drop down to:
DropDownStates.SelectdValue = "Ohio"
I get an error that the value does not exist in the dropdown even though it does exist. But if I pad the value with the correct number of spaces to the right, it works like so:
DropDownStates.SelectdValue = "Ohio "
or
DropDownStates.SelectdValue = "Michigan "
How can I either define the dropdown without trailing spaces in the value of the dropwdown or set the SelectedValue with adding trailing spaces?

What is the proper way to set the selectedvalue of a DDL inside a web user control? My current structure is PAGE > USERCONTROL [FORMVIEW] > USERCONTROL [DROPDOWNLIST]Inside my FORMVIEW user control, I am setting the value of my DROPDOWNLIST user control through an exposed property located within the DROPDOWNLIST user control, called SelectedLocation. However when I changeMode of the FORMVIEW control, depending on where I call my method to bind myROPDOWNLIST, it will either bind it twice or won't bind it all.
