I have a dropdown list where the items displayed in the list are names, and the DropDownList selectvalue is Person_ID.
How do I get the text of the name selected in the dropdownlist and not the SelectedValue?
I have a dropdownlist, and a Gridview where one of the columns is a dropdownlist. both dropdown lists use the same data source. When a value is selected in the dropdownlist (outside the gridview) I want to chaneg the selectedValue and selectText of every dropdownlist in my gridview. This is what I have tried:
Dropdownlist:
<asp:DropDownList onclick="javascript:onJDSelection()" ID="DropDownList3" runat="server"
DataSourceID="SqlDataSource4" DataTextField="circt_cstdn_nm"
DataValueField="circt_cstdn_user_id">
Javascript:
<script type="text/javascript">
function onJDSelection() {
var jd = document.getElementById('DropDownList3.ClientID').selectedText;
var grid = document.getElementById('GridView2.ClientID');
//Loop starts from 1 because the zeroth row is the header.
for (var i = 1; i < grid.rows.length; i++) {
var OtherText = grid.rows[i].cells[2].innerText; // Works fine
grid.rows[i].cells[3].getElementsById('ddl_JD').selectedText = jd;
}
}
When I click I get an error. It says object expected. However I know those objects exsist!

I am trying to add a client side event to a dropdownlist and I need to access the currently selected Text. I have tried:
ddl_tech.Attributes.Add("onclick", "document.getElementById('" + chk_techreview.ClientID + "').disabled = this.options[this.selectedIndex].text.Equals(' UNASSIGNED');");
and
ddl_tech.Attributes.Add("onclick", "document.getElementById('" + chk_techreview.ClientID + "').disabled = this.text.Equals(' UNASSIGNED');");
Both of which give me runtime errors when the event is fired.Whats the correct way to access this text property client side?I tried this but it does not enable the checkbox...
ddl_tech.Attributes.Add("onchange", "document.getElementById('" + chk_techreview.ClientID + "').disabled = this.options[this.selectedIndex].text == ' UNASSIGNED';");
ANSWER:
Well, along with having to use == rather than .Equals, when you set a checkbox.enabled = false on the server side it raps the checkbox in tags and sets it to disabled=true; therefore you must set BOTH the checkbox.disabled = false and checkbox.parentElement.disabled = false; on the client side to enable the checkbox!The solution:
ddl_tech.Attributes.Add("onchange", "document.getElementById('" + chk_techreview.ClientID + "').parentElement.disabled = (this.options[this.selectedIndex].text == 'UNASSIGNED'); document.getElementById('" + chk_techreview.ClientID + "').disabled = (this.options[this.selectedIndex].text == 'UNASSIGNED');");

View 7 RepliesI am having a problem with disabling DropDownList based on the chice of 1st DropDownList, there is no post back occuring, and it is a template based web app here is the current code:

I have a .net 3.5 web form with an ajax combo box and a text box inside it. The bombo box is bound to a SqlDataSource.
My requirement is to show/hide the text box depending on the text of the selected item in the combo box. If a particular string, say 'xyz', appears in the text of the selected item, the I will make the text box invisible. I enabled the AutoPostback, made the text box disappear in the SelectedIndexChanged event, and everything worked fine.
However, when users enter their own texts (which are not in the list items), I am unable to show / hide the text box. I've tried the TextChanged event but nothing happens. It seems the event is not trigger after I enter a new text and locate the focus to other place.
is there a way to prevent the user ented text from being inserted into the bombo box?
I am binding months to a list 0-13 items default selection is 0 months duration, and years 0-8 items and 0 years is the default selection.As I know there are always going to be 12 months in a year, I could use selectedvalue or selectedindex without any perceived problem. Is there a reason why I should not use either/or of the two properties to select a list item?
View 2 RepliesList controls deriving from ListControl, such as DropDownList, ListBox or RadioButtonList, are populated by a list of ListItems. A ListItem has a Value and a Text property.
ListControl offers the following methods to access the currently selected item:
ListControl.SelectedItem returns the currently selected ListItem,
ListControl.SelectedValue returns the Value property of the currently selected ListItem.
Now, the interesting thing is:
ListControl.Text returns exactly the same value as ListControl.SelectedValue. It does not return SelectedItem.Text, as one might expect.
This is by design:
[code]....
The Text property gets and sets the same value that the SelectedValue property does.
This seems counter-intuitive and confuses people. My question is: Why was it done this way? I can imagine that providing a Text property is necessary for implementing the ITextControl interface, but why on earth would you choose to have it return the Value of the ListItem rather than the Text?
I am trying to make a simple dropdownlist.Based off what is selected as the dropdownlist, I want it to open a new webpage.
For example:
Here is the dropdownlist - If they select team1, I want it to open up webpage /team1.aspx If it's team2, team2.aspx and so on.
<form id="form1" runat="server">
I thought this would be pretty simple, and in fact it's working on another dropdownlist on the same View, so I'm hoping I missed something very small that is easy to fix. Here's my code:
[Code]....
When I step through the code, the 'Active' option's 'Selected' property is being set to true. That's expected. But when the View renders, it's not selected and a look at the page source shows that the selected property isn't set. What is the problem here, and what's the solution?
how i handle this problem..Its in hidden filed.
