Web Forms :: Design Multi-fileupload Control Like Orkut.com?
May 11, 2010
I want to develop the multi-file upload control in asp.net using c#,.. the control should be just same as the control present in the orkut.com,... but with some modifications,... as in the orkut the control provides the facility to add multiple files,.. but i want to make the maximum number limited to the admin choice,... as if the admin wants that he will give option to upload 10 files,.. then this control should get only 10 file upload controls,.. and if admin set this value to 100 files,... then the control should only be 100,...
i want show images(like orkut friend list ) which controle is best to use whenever add friend that friend profile image automatically show in my profile if any one have source code or link means send to me
I've been asked to re-write an existing VS 2003 applicatoin in VS 2010. The application contains multiple sections that allows certains users the ability to edit based on security roles. Each user is able to view the sections. There is ton of code to enable/disable section permissions for each user. Is there a better option available in VS 2010? I'm not too familiar with MVC and not sure if it would work in this scenario - each section should be available when the users login.
I have created my webpage in asp.net in 1024*768 resolution, my problem was that when i change my monitor resolution then the controls in my webpage will be displayed in unmanaged manner. How to arrange items in my webpage which support multiple resolution. Whatever the resolution of my monitor the controls in my webpage will display as it is as managed in 1024*768 reolution.
I need to create a singleton that would hold lots of data for a spedesign patterns - Singleton behavior with multi-user requests in ASP.NETcific user. However, I am not unclear as to what the behavior of that singleton is in regard to multi-user app requests.
Here is the scenario:
On AppStart event I want to load common data for all users (from SQL) and store it as a collection somewhere within the ASP.NET storage mechanisms.
If I store that data in the cache, I would also have to create a static property in the Global.asax that would provide access to that the data from the cache.
This is not ideal because whenever an instance of any particular page, or generic handler, or what have you tries to query this data using Linq the property has to load the data from the cache... introducing latency. I need this data to be immediately available. (think of it as about 5K rows of data stored in collection of objects...)
I was thinking to use a singleton to get that data, and store it but I don't know how it would behave between requests (and postbacks), as well as application instances, in terms of its persistence.
On PostAuthenticate event I want to get user specific data from SQL in the form of a collection. If i store it as a singleton (in a similar manner as the common data) i am not clear as to:
How is the data persisted? What is the scope of that singleton (it should be for the duration of the user session). How can I ensure that the data is immediately available to whatever needs to consume it? What happens between post-backs to that singleton? If another user logs in would another instance of that singleton be created for that specific application instance?
Our current application is working fine but when you try to misbehave like we found out that When login with same user in multiple tab with different organization(there is a organization dropdown in the master page which sets the cookie whenever it is changed.) in tab one it is org 1 and tab 2 it is org2 , cookie has the later org 2 in it but when we go back in tab1(which had org1) and save the record org 2 will be saved with the record So can some one share some sort of a checklist with us which address these types of problem.
How to get data (read file) chosen in FileUpload control without FileUpload.SaveAs Method on the server? Is it possible write it at once to some object?
I have a FileUpload control in an UpdatePanel and when user select a file, the full file path will will be stored in a hiddenfield, and during postback, i would like to assign the full file path in the hiddenfield back to the FileUpload control textbox, possible to achieve that?
give me some guidance for developing a orkut like application When the user(u1) clicks on Recent Visited profiles, page should be directed to that recent visited user(Vp1) profile and then details and recent visitors for VP1 should be shown
i create a composite control as can be seen in code below, and add this control to webform, assign FormView1 to the HeaderControlName property, Run the page, the system will generate parse error message : Cannot create an object of type 'System.Web.UI.WebControls.FormView' from its string representation 'FormView1' for the 'HeaderControlName' property. However, if i don't assign FormView1 in design screen and manually (through coding) assign FormView1 to the custom control on init, it works as expected.
custom control public class CmdTest : CompositeControl { public virtual FormView HeaderControlName { get { object oObject = ViewState["HeaderControlName"]; return (oObject == null) ? null : (FormView)oObject; } set { ViewState["HeaderControlName"] = value; } } protected override void CreateChildControls( { Controls.Clear(); Button xx = new Button(); Controls.Add(xx); } } webpage.aspx (assign FormView1 in design time, it will generate error) <Utils:CmdTest ID="CmdTest1" runat="server" HeaderControlName="FormView1" /> webpage.aspx (didn't assign FormView1 in ASPX, but assign it on Init Code, it works) <Utils:CmdTest ID="CmdTest1" runat="server" oninit="CmdTest1_Init" /> Webpage.aspx.cs protected void BsCmdTest1_Init(object sender, EventArgs e) { CmdTest1.HeaderControlName = FormView1; }
I have a custom control with four checkboxlist(Country, City, Outlet, Stores) controls in it. The functionality is.. if a country is selected cities would be populated similarly outlet depends on city and stores depends on outlet. I am using the same functionality through out but in one webpage I need to disable the multi selection property of the country checkboxlist without disturbing others.Following is the javascript for the checkboxlist controls:
<script language="javascript" type="text/javascript"> function CheckBoxListSelect(cbControl, cbxControl) {
When I sign in in gmail and I open orkut in the new tab or new window then automatically I am signed in in orkut without entering username and password. How this functioanality works..? And when I sign out from either site, I am signing ou from other site also..is it done by session handeling or by cookies..? what is the mechanism behind this functionality..??
Once the user selects a file in the first control, I want to set the default value for the 2nd control to be the value from the first control.
For example, if it were textbox controls I would just use TextBox1.text = TextBox2.text.
How do I do this for FileUpload controls? I tried a few different properties, such as FileUpload1.FileName = FileUpload2.FileName but I get an error saying that they are Read Only.
I would like to simply have an image button on my page that would show an image that says something like "Upload File".When the user clicks the button I would like for it to automate popping up the "select file dialog" exactly like the "browse" button does on the FileUpload control now. Then if the user selects a file and click "OK" I want to do a post back where I can then initiate the upload. If the user clicks cancel from the dialog I would do nothing.So all I am trying to do her is make it so that the user does not see the text box for the file name and replace the plain old browse button with an image and do a postback if they click ok from the dialog.
i want when i click on button it do some thing like FileUpLoad control i means when click on button it open mycomputer window and we can select file and it upload file to server exactly like fileupload control How i can do it?
