C# - DropDownList - Show Only Ten Elements And Scroll?
Apr 1, 2010
I have one dropdownlist like this bellow.. the problem is that if I have more than 30 ListItem the list will have 30 elements/rows display and the rest to scroll. Is there a way to show only 10 elements and scroll the rest? I read in some pages that this is not possible. Is that true?
I have a DropDownList displaying around 75+ values and it shows a scrollbar. The problem is when the page displays the DropDownList, I can't scroll to the first few items in it. It kind of goes outside the explorer.
The only way I can get to it is by downsizing the page using maximize button and then access the list. I'm using VS 2008.
Basically I want to load a HTML document and using controls such as multiple check boxes which will be programmed to hide, delete or show HTML elements with certain ID's. So I am thinking I would have to set an inline CSS property for visibility to: false on the ones I want to hide or delete them altogether when necessary.
I need this so I don't have to edit my Ebay HTML templates in dreamweaver all the time, where I usually have to scroll around messy code and manually delete or add tags and their respective content. Whereas I just want to create one master template in dreamweaver which has all the variations that my products have, since they are all of the same genre with slight changes here and there and I just need to enable and disable the visibility of these variants as required and copy + paste the final html.
Any tips/code that you can suggest to achieve the desired effect with the least changes required to existing HTML documents? Ideally I would want to load the HTML document in, have a live design preview of it and underneath have a bunch of well labelled checkboxes programmed to hide, delete or show elements with certain ID's.
I have a an asp.net label control on my page.I have set the style to overflow: auto.
I have a gridview which has an edit button. If the edit button is clicked, then textboxes appear that allow users to enter data. The problem is if i scrolldown the gridview and i click the edit button, the page posts back and the scroll position is not maintained.
I've got a dropdownlist in a formview which the user can change and click update and it updates the table field.At the moment, the list displays all the possible headings in the table, which are the names of section headings for a website, e.g. about, contact, portfolio etc.I want the ddl to show all the items, but I want the selected item to match the SectionID in the database table?
i have three dropdownlists ....First contains Countries, second contains States within that specific country, and thrid contains Cities within that specific state...now, i have filled first dropdownlist through database... after selection of country i filled the list of state within that selected country through database... then after selection of state i filled the third dropdownlist with cities through database.....for that i have used update pannel... but because of servertrip to get the specific state list of city's list from database ..... that dropdownlist get blink...and for that i want preloader for that state and city dropdownlist....means when i select country instead of that dropdownlist get blink i want to show any symbol ofprocess or "Loading...." text into that dropdownlist of state... and for city also.
this is my Question extension to this Question..Here I am able to add the Dropdown list value to the Grid.. perfectly.Ex: in my Dropdownlist box I have A B C D items.When I add any Item I am displaying the grid and I am reloading my page.My grid have two columns one is added Dropdownlist value.. other is some other text value..each row in my grid have Edit button.When I click Edit I am reloading my page to edit this selected dropdownlist value.when I click Edit I need to show what ever the Dropdownlist value I have in the grid I need to show in the Dropdownlist..so that user knows he has this dropdown value..
I have an .aspx Page with dropDownList, where you can choose State. The list contains 50 States. Then I have a GridView displaying all the stores of this particular state, which is dependent on dropDownList through the SQL Data Sources WHERE clause.
But the problem is, every time I change the State in the dropDownList and subsequently refreshing GridView - the page URL stays the same dealers.aspx.
I don't want to create 50 pages for 50 States, but now I need to have 50 different URL's. Is there a way to change URL's dynamically, based on dropDownList choice? And so people can get directly to URL of choice. For example dealers.aspx/California.
I am filling a dropdownlist and sometimes the value (text) is much longer than what is viewable. Is there an easy way to have user see the full text. I am currently using "ASPNET_MsgBox(Message)" and it works but looking for a better solution.
I have a dropdown list which include "yes" and "no". When I click "yes", then there have to be 2 text boxes visible, just below the dropdownlist. If the user selects "no" in the dropdownlist, then the 2 text boxes have to disappear again.
I'm using a text book to teach myself ASP.NET 3.5. I'm using Visual Web Developer 2008 express to create my pages. At this point in my text, the author has me drag a DropDownList control to the Web page and then tells me to go to the Properies window and look at the Items property. I don't see an Items property. I've doublechecked that I'm on my DropDownList control, but I see no Items property. Is this a bug in VWD, an error in the book, or just plain old User error?
I'd be willing to hard-code the property in the source window, but I don't know the syntax. I tried items="Vanilla, Chocolate" but nothing appears in the list when I view the screen.
I'm working on web pages that have an ASP DropDownList defined, and on page load the data source is bound to it through DataSource.DataBind(). When I step through the code, the drop down list does not show anything in it, but when the page actually displays, it does have items in the list. When exactly does DataBind() get applied to the control?
The problem is that some of the values returned by the SQL back end have a null Text, so nothing is displayed in the drop down list for that row. I want to just use the Value as the Text, but only if the Text is null. And when I put the code to loop through and do that right after the DataBind(), there is nothing in the drop down list at that point in the code.
I've got two DropDownLists that are filled using a couple of SqlDataSources, like so:
The third DataSource, dsCriterias, is used to present a set of dynamically added DropDownLists depening on what's selected in the second DropDownList, subcategories. The set of dynamic DropDownLists are presented using this code:
The code works but there's little thing that's bugging me. When the page is first loaded the criterias belonging to the subcategory is not presented. I expect it to show the criterias but ther won't show until I make a choice in the categories-DropDownList meaning if I wan't the first subcategories criterias I have to choose different subcategory and then go back to the first one. It's a bit hard to explain.
An example: When the page is first loaded I get a category presented, eg. Vehicles. In the subcategories I get the alternatives "Bicycles", "Cars" and "Motorcycles". "Bicycles" will be the one presented when the page loads since the stored procedure used by dsSubcategories sorts the data by the subcategory names. The problem is that I don't get the criterias for the "Bicycles" subcategory at page load. To get them I first need to select "Cars" or "Motorcycles" and then choose "Bicycles".
I've tried putting a subcategories.SelectedIndex = 0 in in the OnLoad but nothing seems to do the trick.
I have a dropdownlist populated by a table containing ID and Name field. I am showing a textbox and add button if the user selects "Other" option from that dropdownlist. When a user fills the textbox and hit that button it binds the dropdownlist. But I am struggling to figure out how to show the textbox value immediately in the dropdownlist after they hit the add button. I don't want my users to scroll down the list to find the newly added item. Please provide sample code.
I am using these: ASP.Net 2.0, VB.Net, Visual Studio 2005, SQL Server 2005, Formview controls
In a ASP.Net form I have 20 textboxes and 20 dropdownlists(ddl). All ddl(s) are databound and get the data from a single objectdatasource. All textboxes and ddl(s) support null values. Textboxes are for entering numbers and ddl(s) are for selecting the unit (mm, cm, in, m3, oz, qt like these.).
I am using the below code to achieve two things.(For each textbox and ddl have their own corresponding codes like below.)
1. Allowing the selection of ddl item also if it is not selected too, a default unit item will be inserted in the database.
2. Only if textbox has value then the default unit item will be inserted in the database.
It is working fine.
Part of form below:
How to set & show default value in dropdownlist from databound items (not static) OK, I tried this way and worked for 2 instances. But 3rd ddl onwards are not working and giving the error "Object reference not set to an instance of an object".
