Web Forms :: How To Retrieve The Selectedvalue For The Radiobuttonlist

I am experiencing the "Input string was not in a correct format." error and I have no clue how to fix it.

I have a radiobuttonlist and a submit button, the radiobuttonlist is dynamically bounded to a datasource. when user clicks on the submit button, I am trying to retrieve the selected value in the radiobuttonlist, but somehow the radiobbuttonlist selectedvalue is null. How to retrieve the selectedvalue for the radiobuttonlist?

The aspx form code is as below:[Code]....

aspx.cs code: [Code]....

The form displays the radiobuttonlist listitem value without problem. However, the rdChoice.SelectedValue is null.

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:

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.

Forms Data Controls :: How To Bind RadioButtonList SelectedValue

Aug 18, 2010

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.

Web Forms :: Add Eventhandler To Radiobuttonlist Dynamically To Retrieve Selected Value?

Feb 24, 2010

A new route to an old problem for me... I'm creating radiobuttonlists and adding them to an update panel dynamically using this code:

[Code]....

I'm wanting to get the selected radio button value whenever a button on the page is pressed, however (and this is my old problem) I cannot retrieve that value. What I'm wanting to try is to add an event that will record the chosen radio button whenever the selected value has changed and store it into an array.

AJAX :: Retrieve SelectedValue From CascadingDropDown Lists?

Oct 20, 2010

I followed a tutorial yesterday to implement CascadingDropDown lists but I can't find many examples of how to retrieve their selected value.

Can this only be done using javascript?

Is there any way to access the SelectedValue of the CascadingDropDown lists in the codebehind?

I'm using them in an EditItemTemplate, in a DetailsView, on a master/details page.

Setting SelectedValue For One DropDownList Also Updates The SelectedValue For Another DropDownLIst

Jul 21, 2010

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]....

Web Forms :: Setting SelectedValue In Dropdownlist

May 11, 2010

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?

Web Forms :: Dropdownlist SelectedValue Not Changing?

Aug 26, 2010

I have a quick question on my ddl. I have a search page that searches based on the ddl. Once the button is clicked. the result of the search shows on the gridview.Which all works well.Now the problem i am having is that. On my gridview i have a select button that brings out another ddl on an update panel based on the first ddl. When i do this... it goes back to the first record on the ddl and shows a wrong result.. Basically the new ddl is supposed to change on "selectedindexchanged" handler of that gridview which works fine but the selectedvalue is just going back to the first one.
