Web Forms :: Dropdownlist Listitems Expanded In MSIZ?

Feb 1, 2011

I need to get a dropdownlist itemlist to expand in MSIE. The width of the dropdownlist control is set to a fixed width and it cannot be altered onclick, so I need to have the list of items that drops down when clicking autoexpand widthwise. I have tried several different jquery options that are out there, but they are not stable because they do not work on every click and sometimes forces the user to click twice for the itemlist to appear. Displaying a tooltip is not enough, I need to see the list expanded.

The list should look like this;

**DROPDOWNLISTCONTROL**

**LONG CONTENT THAT STRETCHES WHEN EXPANDED**

The list currently look like this in MSIE, and I cannot expand the dropdownlistcontrol,

**DROPDOWNLISTCONTROL**

**LONG CONTENT THAT STR**

Is there anyone who knows of a smart way to do this?

C# - Force A Line Break In The Listitems Of A Dropdownlist?

Feb 1, 2010

I have a dropdownlist that I already have manually databinding. I currently get the data, loop through each item, and depending on values in the item, change the css for the individual ListItem.

For example:

foreach (Site mySite in myList)
{
ListItem li = new ListItem(mySite.FullAddress, mySite.Id.ToString());
if (mySite.DisabledFlg)
{
li.Attributes.Add("style", "color:#999");
}
this.Items.Add(li);
}

I'm trying to force the text in the listitem to break at certain points. The string that I retrieve from the datasource currently has a " " everywhere where there should be a line break. This works fine for display in a normal textbox, but it doesn't work on the listitem. I've tried replacing the " " with a "<br>" but when I do that, it just displays <br> in the listem along with the rest of the text. I've tried wrapping the listitem contents in a "div" with a width attribute, but it also just display the "div" tag literally in the ListItem text. I've also tried adding the following to the ListItem attributes at bind:

li.Attributes.Add("width", "100px");

But that hasn't resulted in any change either.

I've seen custom drop down list controls that have multiline listitems in them.

Web Forms :: DropDownList With Multiline ListItems - Expands The Width Of The List

Jul 28, 2010

I have a DropdownList where some of the items are longer then the width of the list. Firefox expands the width of the list and shws the full length of the ListItem, but Explorer (som people still use that) doesn't do that which results unability to read the whole of the ListItem. I added a "Title" attribute (Tooltip) to the ListItems which shows the full text but even though, the client asks if it's possible to split long ListItems in several lines so user will be able to read it without needing the Tooltip.

Forms Data Controls :: DetailsView DropDownList Do Not Find ListItems Entries?

Mar 30, 2010

I am using Visual Studio 10/ASP4 but I am sure this problem is me. I created a program and got it all working. GridView and DetailsView, edit, insert and delete all works. :-)... I have spent 4 solid days attempting to have a simple DropDownList with three items on it EDIT a record. Lots of GOOGLeing for suggestions. It just will not work. The insert dropdown works fine(thats how I created the record). I wrote a new simplified program with just the detailsview and the edititem dropdownlist. Still can't get it to work. The detailsview data has a record and the "mode" field (char(20)) has three letters "FTP" in it. The letters display on the Detailsview. I can edit fine but when I add the following drop down list the page aborted with a

"'DropmodeEdit' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value"

Yet there is only one record and it HAS "FTP" in it! The list has FTP in it? I just don't get it, why?

I added an ondatabinding routine and breakpointed it in the try/catch and found the selectedindex pointed to the correct entry and the items list had the correct entry with no spurious data or spaces. The data being passed displayed good in the detailsview, Am I correct in assuming that is bound to the dropdownlist automatically? or is there some majic that I did not get from Rob Burke?

<asp:TemplateField HeaderText="mode" SortExpression="mode" >
<EditItemTemplate>
<asp:DropDownList DataValueField="mode" DataTextField="mode" ID="DropmodeEdit" Runat="server"
OnDataBinding="mode_OnDataBinding" AppendDataBoundItems="True"

[Code]....

I have used a dropdownlist once before with a datasource instead of listitems, this should be easier?

C# - Disable Or Enable 2nd Dropdownlist In Aspx Based On Selected Choice Of The 1st Dropdownlist Box

Apr 15, 2010

I 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:

<script type="text/javascript">
$(function() { var dropDownList1 = $('#<%= ddlUserType.ClientID %>');
var dropDownList2 = $('#<%= ddlMember.ClientID %>'); dropDownList1.change(function(e) {
if ( jQuery("#ddlUserType").val() != "ETOC") dropDownList2.removeAttr('disabled'); e.preventDefault();
else
dropDownList2.removeAttr('enabled'); e.preventDefault(); }
} );
</script>

what is happening now is page is blank and if I remove the above code everything shows, where I am going wrong. here is the plain and final javascript code which worked:

<script language="javascript">
function CheckDropDownState(lstbox)
{
if (lstbox.selectedIndex == 3) { document.forms[0].ddlMember.disabled = 1; }
else { document.forms[0].ddlMember.disabled = 0; }
}
</script>

and thew .aspx code: <asp:dropdownlist id="ddlUserType" runat="server" onclick="CheckDropDownState(this);"></asp:dropdownlist>

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)

[Code]....

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:

[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

C# - Populating Dropdownlist Using MVC2 Based On Another Dropdownlist (Cascading)

Sep 18, 2010

I am making an application that deals with vehicles. I need two DropDownLists:

Makes: All Vehicle Makes
Models: Models that belong to the selected value of the Make DropDownList

How is this done in MVC2? My Idea: Do I use an ajax call when my first list is selected and then pull back the Models to bind to the Model DDL? How would model binding come into play that way? UPDATE I posted what I ended up doing as an answer. It is super simple and works great. You can use a get too if you feel so inclined, but you have to specify that you want to like so... return Json(citiesList, JsonRequestBehavior.AllowGet);

VS 2008 Dropdownlist Selection Disables / Enables Another Dropdownlist

Aug 1, 2013

I have a dropdownlist on my page with dates such as 1/1/2013, 2/1/2013, etc.

Then there is a second ddl.

If the date in ddl #1 is before 1/10/2013 I want to enable ddl #2.
If the date in ddl #1 is on or after 1/10/2013 I want to either disable ddl #2 or hide it (whichever's easier).

Disabling ddl #2 based on the selected date is a new requirement so I am enhancing the existing code. Obviously I want to do this without a postback, but I don't know what is the best way. I am trying to understand what an AsyncPostBackTrigger is because this is the existing code:

Code:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:dropdownlist id="EffectiveDateDropDown" runat="server"></asp:dropdownlist>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="QuoteType"
EventName="SelectedIndexChanged" />
</Triggers>
</asp:UpdatePanel>

It wants to do something when the selected index is changed? This exists in the code-behind, but I set a breakpoint and never hit it:

Code:
protected void QuoteType_SelectedIndexChanged(object sender, EventArgs e)
{
try
{
}
catch (Exception err)
{
this.PublishError(err);
}
}
