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.

I have a dropdown list in a gridview field. The DataValueField for the ddl is an 8 digit item code. The text to display through will be quite longer, 40-60 characters because it will combine the item code and item name into a single string. I don't want the dropdownlist field to be that wide though, only what is displayed when the ddl is selected.In Access you can set the width property of the list to display wider than the field itself. Is there that capability in ASP.NET and if so where do I find it?

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?

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"

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

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.

been trying long time now to style the width of columns of a checkbox list, trying to group text by similar lengths, something like this:
small width [] wider width here [] widest width of all here []
small wid [] wider width h [] widest width of all h []
small widt [] wider width her [] widest width of all her [] (of course the checkboxes line up in the actual form)
so smaller length texts are not too far away from their checkbox, the checkboxlist control seems to have an iron grip on those col widths

I have a rather weired problem with ASP.NET menu control. It stays expanded (displays all menu and sub-menu items) until the page is loaded completely. Once the page loads, the menu returns to its normal position and sub-menu items are not shown. This issue is seen on IE, Mozilla, Chrome, so cannot be browser specific issue I am using AJAX control toolkit, collapsible update panels on my page.

Just getting started on ASP .NET and I have a question. I've created a user control that is show's an image. Using a place holder I add 5 items of that control. The problem is that in the display it shows me the control's vertically and I want it to be shown horizontally. Just to demonstrate what I mean (the numbers are the user controls been added):It shows:
1
2
3
4
5
I wanted to show: 1 2 3 4 5 I've tried a few thing's such as using a table - but the table expands with the place holder so It didn't make a differences.

I have an ASP.NET AJAX autocomplete extender with CompletionListCssClass=autocomplete_completionListElement :
.autocomplete_completionListElement
{
width:500px;
margin : 0px!important;
background-color : inherit;
color : windowtext;
border : buttonshadow;
border-width : 1px;
border-style : solid;
overflow :auto;
height : 200px;
text-align : left;
}
But for some odd reason the width of the auto complete list always takes up the width of the textbox even when I set the width to 500px.

Is there any way to set the width of a GridView to a pre-determined width?
I have set the width of the gridview and all the columns to a % and then to a number of pixels but it does work. The gridview always sets itself to a width required to display all fields and it goes beyond the resolution of the screen. I would like to contain it to 1024 pixels.
Here's my .aspx

I have two web parts. Web part #1 is a weather widget using a HoverMenuExtender, and #2 is a news items rotator type of deal. Both are separate parts, each wrapped in an update panel. The news rotator update panel has a timer placed within the contenttemplate tag. The weather widget does not. The problem that I am having is that when the timer's Tick event occurs, the HoverMenuExtender expands and will not contract again until the page is refreshed (I also get a javascript error about an unknown runtime erro in IE).
I am wondering what is going on to cause this behavior/error? What I am looking for is to have the news rotator panel update on its timer's tick event, and the weather widget to do its expanding when the user mouses over it (like it should, and it does work in the absence of the timer).

Need a little guidance on handling selected items in a listview and sessions.
First, the CheckBoxList looks like this:

In the code behind for that page, I'm trying to put the store the selected values into the session like this:

Finally, I want to retrieve the items and wind up with a string containing the items (I think I want a string--what I need to do is put the items into a variable so I can display them in a Label control and also include them in the text of an email that gets generated. Here is how I'm attempting to retrieve the items:

But my variable "Opportunities" ends up with this value: "System.Web.UI.WebControls.ListItemCollection".
