i have limited my list box width with the style "list_style". my problem is that some of the item in my listbox has length greater than my listbox width. i need to limit the length of the item shown with a '...' if the length is too long. so my text will be 'how are you ...' for '
I have two list boxes, one has a list of available users (about 1500 items) and the other is blank. There is a button to add the seleted items from the first list box to the second one. Both of these listboxes are within an update panel and for some reason it takes over 20 seconds for the items to show up in the second listbox.
Is this normal? Is there an alternate, faster way of doing this?
I've been searching the web and no luck. Can someone tell me how to assign values to my listbbox? I used the ValueMember property but when i have more than 1 item it is only set to one value member instead of each of its own.
There are quite a few questions around this topic,but I can't seem to get it figured out.I'm trying to bind a listbox to an ObservableCollection and keep the listbox updated when items are added to the collection.
Beyond this, I have a simple textbox and button on a page.When a name is entered into the textbox,and the button is clickedI call the addBlog(passing in name from textbox) sub routine in the ITRSBlogs Class (back up the page a bit) to add the item to the collection.Problem is,when I add an item to the collection,the listbox is not updated.I'm new to Observable Collections (and many other things : ),so maybe I'm just really off here.
I have a listbox, i am binding it to a datatable with DataTextField and DataValueField. This is in WebForm (not windows).And the first item in ListBox is "Select All" and the rest are from DataTable.SelectAll is selected by default.1) If i select any other item...(as it is multiselect) the "select all" item should be unselected.2) If i select 5 items in ListBox and after that i select "Select All" items then all the other items except "Select All" item should be unselected.
I have a textbox that searches the listbox below it and selects the text that I types in the textbox. Now although the item is selected in the listbox I have to scroll to the end to see if the item is selected ornot IS there a way that I can make the list box scroll to the selected item?
The ListBox is in the EditItemTemplate of a FormView inside of an UpdatePanel. jQuery is possible but it would be great if there would be an asp.net serverside(or Ajax) way to achieve this because i don't want to use more client scripts than really needed(and this is only a nice to have).
In ASP.NET I have a dropdown with some items in it, I have a button and a textbox. I am subscribed to the SelectedIndexChanged event of the dropdown where I pass the new selected index of the dropdown to a struct that converts it's index (via enum) to a string. That string is then gotten through a property in a class to put into the textbox.
Now the problem I have is that, when you click it (the button) the first time, the action get's updated with the current action selected in the listbox, but then when you click the button again WITHOUT changing anything in the listbox, the textbox shows the zero'th item in the textbox, (seems to reset), although it actually hasn't changed at all.
I'm guessing this might have something to do with the postback caused by the button click, which resets the state of the global or something, but I'm not sure. Why is it being reset while the dropdown box is still as I set it the first time?
How can I pre-select a drop down list box item in a listbox? I experimented using Asp.net and C#, but was not able to pre-select a drop down listbox item.
I am not on my coding box right now, but basically as an example of what I am talking about, if I have the following drop down listbox items.
--Select-- New York Jets New England Patriots Green Bay Packers Atlanta Falcons SF 49'ers Oakland Raiders
How would I pre select the team name of "Atlanta Falcons" using C# and Asp.net? Spefically based on the string of the team name "Atlanta Falcons" instead of an alternate way like using the Selected Index function?
