C# - Bind SelectedValue Of DropDownList To Nested Property?

Feb 10, 2010

I have a asp.net FormView with a DropDownList for the selection of a month. The FormView is data bound to an ObjectDataSource.

<asp:DropDownList ID="MonthsList" DataSourceID="MonthsListDataSource" DataTextField="Value" DataValueField="Key" SelectedValue='<%# Bind("OrderDate.Month") %>' Width="100" runat="server" />

I like to bind the selected value to the nested property 'Month' of 'OrderDate' as shown above. The property OrderDate is of type DateTime. The error I'm getting while binding to a nested property is:

A call to Bind was not well formatted. Please refer to documentation for the correct parameters to Bind.

C# - Validate Dropdownlist Selectedvalue Against A List From Static Property?

Oct 4, 2010

I am using javascript to validate user input on my aspx page. I am easily able to validate textboxes and dropdown list for differenet scenarios.

Now, on one of my dropdown lists (for country), I need to check if it is an allowed country or not for a particular service. I have stored the valid country list in a static property. Is there a way to validate my dropdownlist selected value against that static property?

function validateService(source, args)
var country = document.getElementById('<%= ddDestCountry.ClientID %>');
var service = document.getElementById('<%= ddService.ClientID %>');
// Get allowed country list from my static class
var countryList = document.getElementById('<%= StaticProperties.EUCountryList %>');
if (service.value == "P")
// I want to do something like this
if (!countrylist.Contains(country.value))
args.IsValid = false;
else {
args.IsValid = true;

Update(Additional Information): The static property is read-only so it cannot be tampered with from the page.

Web Forms :: Nested Dropdownlist Ondatabound => Bind Other Dropdownlist Fail

Dec 9, 2010

I have a gridview with 3 nested dropdownlists in one cell on edit like this:To get the exact fields when the user clicks on edit I used the following code(yes it's messy)


The BLLOnderhoud is a class and the getReserveInfo is used to get the Model - Brand(merk) Information.Since the dropdownlists are nested in the gridview I can't call them directly and they can't call any of my functions.And this is the problem, when I change the dropdownfield Model the Auto field wich is the last dropdown(in the picture is a typo) should be binded like in the following code:


But the dropdownlist onDataBound event can't call any of my functions that are in my class.So my question is how can the onDataBound event of the second dropbox trigger a function? The only thing that the function has to do is to bind the 3rd dropdownlist

Web Forms :: "Bind" Web User Control Property To Grid View SelectedValue?

Feb 2, 2010

This is driving me nutty... I have a gridview on a page. On the same page is a web user control with several public properties. Using the gridview's selectedindexchanging event, I try to set the user control property, but it's always null. Like this:
protected void grdPhysicians_SelectedIndexChanged(object sender, EventArgs e)
usercontrol1.ID = grdPhysicians.SelectedValue.ToString(); [code]....

If I write the grdPhysicians.SelectedValue to the page, I can see it's there. It just won't pass to the web user control.What I'm trying to do is have a master record form with child records in a web user control and just pass the selected record id into it.

protected void grdPhysicians_SelectedIndexChanged(object sender, EventArgs e)

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());


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]....

Forms Data Controls :: Conditionally Bind Text Property Of DropDownList

Dec 8, 2010

I'm modifying an existing application. I need to be able to bind the Text property of an asp:DropDownList control to one of two fields when the page is rendered. The existing code is like this:


I've tried to use conditional logic on the .aspx page when setting the Text property, but everything I've tried results in an error. I've also tried using code-behind to set the Tetxt property in the Page_Load event. This doesn't generate an error, but it doesn't set the property either.

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):


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.

Same result with .SelectedItem.Value and .Text

Why? And how do I get the item actually selected?

Get SelectedValue() Of DropDownList After Setting The Value?

Dec 13, 2010

I have a databound dropdownlist on a page, where in the page_load I set the selectedValue (inside a 'not isPostBack').

Although the page displays fine and shows the correct item as selected.. inside the page_load if I try and get the selectedValue() and display it to the screen, I always get null... selectedIndex is -1.

I have a button, which when clicked refers to this ddl's selectedValue, and here it pulls through the the expected result.. so how come I can't see it immediately after setting it, while still in page_load?

edit: the code..

ddl declaration
<asp:DropDownList runat="server" ID="dlCountryList" DataSourceID="dsCountryList"
DataValueField="countrylistid" DataTextField="description">

and the page_load

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
dlCountryList.SelectedValue = "GR"
Response.Write("*" + CStr(dlCountryList.SelectedIndex) + "*")
End Sub

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 "
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?

C# - Setting SelectedValue Of A DropDownList On PageLoad

Nov 11, 2010

I have a bit of a problem with a DropDownList I am using. When the user changes the SelectedIndex, they get redirected to the same page, but with a query string on the end based on their selected value.

Because I'm not posting, and redirecting instead, the state of the dropdownbox is not saved, so it always defaults to the first one.But, if I save it in say a session, or set the selectedvalue according to the query string in Page_Load, when the user selects another listitem, the selection they have chosen is overridden by the selection delcared in Page_Load.
