Web Forms :: Using Masterpages And User Defined Controls?
Mar 10, 2010
I using Masterpages and user defined controls, on my user defined control I added a CalenderExtender, but I can get it to work, when I set the TargetControlID="txtPSD" the name of my textbox it vanishes from the screen. Question is am I putting it in the wrong place??? see the bold code below, TargetControlID error is name contains uppercase lettter that are not allowed.
I am developing an application in which I have to use a User Control.I have created a user control in which I am using
- A Label (whose text will be dynamic) - 3 Textboxes (whose values will be also dynamic).
So far everything is working fine.Now I used this user control in a aspx page and at the page_load i have to loop thru all the instance of this user control and assign values to them and here the problem begins.The values are not being assigned to the controls.
Here is the code which i have written to loop thru User Control instances and assign values to them.
i created a user control and place a button on it.i drag dropped the user control on a aspx page and wrote the grid load and button clicks in the
user control.now i got a requirement to use the same user control grid and button to again use on the same page.however the data populated will be different and the button click functionality will be different.how can i reload the different data on the second grid as i had already wrote the code in the first one
I am trying to create a type of table on sql 2008. The following sql fails saying Incorrect syntax near the keyword 'AS'. what i am doing wrong as this looks fine to me.
need to let users to generate online questionnaires that could be answered by other users. I was wondering if this could be done using the WebParts.I have a custom application with already set up database. I do not use any form of Membership Provider (I have a custom made form of user authentication, I did not want to be bounded by the rigid frame of the ASP Membership). As far as I know Web Parts uses db (called SharePoint ?) to store the state etc. so this might be the first problem because I do not want to modify my DB just for the sake of WebParts (I assume it would require a whole lot of changes).So I was wondering if it would be possible to use Web Parts only as a form of "ASP code generator" e.g. I could create the questionnarie using WebParts and then export the result somehow (?) to print an ascx/aspx file or code.If this can not be done, can anybody tell me if there are any components that would be useful here? Some sort of toolkit where one could create asp code online? (with textboxes, checkboxes etc.).
I received a user defined XML file and want to programmatically read and display it on a browser using ASP.net. I also want to allow users to add more tags, elements with their attributes according to the existing schema through the web interface used to display the XML. Where can I find some techniques with examples?
Example:
<?xml version="1.0" standalone="yes"?> <bookstore> <book ISBN="10-000000-001" title="The Iliad and The Odyssey" price="12.95"> <comments> <userComment rating="4" comment="Best translation I've read." /> <userComment rating="2" comment="I like other versions better." /> </comments> </book> </bookstore>
The XML file contains a nested structure — each book can contain its property values, as well as one or more comments as separate elements. I want to allow users to view each of the property values and change them as well as add more userComment tags.
I am looking to port my very basic DBMS software from classic ASP to ASP.net - however the user would need to input the connection details in order to connect to their specific DBMS server.
Is this at all possible with ASP.NET MVC (very similar to DSN-less connections in ASP).
Suppose I have a string in U.S datetime format, "2/25/2010" and the server is on U.S East Coast with a timezone offset of "-5". When I convert the string via
Convert.ToDateTime("2/25/2010").ToUniversalTime(), it saved as "2/25/2010 5:00:00 AM" (which is correct as local server time for it is 2/25/2010 12:00:00 AM"
Now, suppose my user is in the U.S central time with a timezone offset of "-6", what I want to do is convert it approriately and when this user from central time do "Convert.ToDateTime("2/25/2010").ToUniversalTime()" type of statement, the datetime saved will be "2/25/2010 6:00:00 AM"
How to develop a user defined plugin for a web browser. It should features: It should be installed in any browsers. It should be executed whenever the browser starts. It should monitor the web page and access the web page that the browser displays. It should monitor and access the web page (for example, getting a value from a text box) irrespective of the web page the browser displays. (The web page can be of any URL either google or any domain)
I created a function and am trying to access it through a case statement, but I am getting the error:
Cannot find either column "core" or the user-defined function or aggregate "core.f_FiscalYear_Open_Days", or the name is ambiguous.
The case statement is below:
CASE WHEN c.program_id = 5 and CAST(minutes) As float)/60 >= @MiddleSyTargetHrs /core.f_FiscalYear_Open_Days(c.program_id,Org_Site_ID_Contract,'7-01-2009','7-31-2009') Then 1 Else 0 End As mon_1_hrs
I have been, exhaustively, looking at examples of WF4 and am not sure it will work for my project. I need to be convinced otherwise. I am struggling with how we would implement a system to use WF4 so users have the ability to define workflows. It seems you need VS2010 experience to design and implement a WF 4workflow. I love wheat it can offer, but feel it may be too complicated for non techical users.
Do we just define a ton of custom activies that a user can move into a workflow? How can we make it as easy as possible for a user to build the workflow?
We have and application that we want to allow, Joe / Jane user to create their own workflows for specific items. For example, Request For Information items. The RFI has specific states it can be in that are defined by the user.
They should be allowed to control the flow based on those states. There will be some base items that the application defines as to what will happen based on a decision / condition. So, things like notifications (who gets notified when something changes), time frames (how long something can stay in a certain state before something else happens), and possibly some other conditions.
The conditions / decision types will be limited by the application, for now. But imagine they can build the workflow and add those decisions / conditions in without any coding knowledge.
I have a base user control (inherited from System.Web.UI.UserControl)
public delegate void MyEventHandler(object sender, MyEventArgs e); public event MyEventHandler ControlLoaded; //Fire the event from here protected override void OnLoad(EventArgs e) { MyEventArgs cmdEventArgs = new MyEventArgs("somearg"); ControlLoaded(this, cmdEventArgs); }
I have several controls that are derived from this base user control.
On the host ASPX page, I need to subscribe to the ControlLoaded event.
protected void Page_Load(object sender, EventArgs e) { //subscribe to the event //This line DOES NOT WORK as I cannot attach event to a base control - It needs an instance of the user control which I don't have BaseUserControl.ControlLoaded += new MyEventHandler(ControlLoaded); } private void ControlLoaded(object sender, MyEventArgs e) { // some control has been loaded }
am having a class which contains user defined data type property. I have created an instance of that class. When I bind that object of that class to DetailsView it is showing all properties except user defined data type property. Here is the sample code.
public class Customer public string CustomerName { get; set; } public int Age { get; set; } public Address CustomerAddress { get; set; } } Address class looks like public class Address { [code]...
I have a public property defined in code behind of a user control. I want to toggle visibility of controls in the markup based on the property's value.
How can I change the default session time in an ASP.NET website to something user defined - perhaps 1 hr?I assume the default session time is 20 mins..
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; }
When using a range validator, if the user exceeds the defined range, How do you code it so it disables a button so the user can't continue. (without using JavaScript)
I am not sure how the user defined class objects are garbage collected. Do I need to implement IDisposable interface on every class and call the dispose() method on it to free the memory?
I am new to Masterpages and thought I would set up some buttons on the left and right side of a masterpage and leave the center open for a ContentPlaceHolder for the stuff I would do in other pages.Is this possible?
