Web Forms :: How To Create Panel With Controls At Run Time
Dec 2, 2010
I am creating an application where up to 50 people could register for an event. On this part of the application, I have a dropdown menu that contains values from 1 to 50 and autopostbacks to create panels with controls inside equal to the number selected in the dropdown menu. The code for that is below:
[Code]....
The code above works pretty well for the most part (I'll explain the small glitch I found more below). But now on a button to submit the registration, I want to grab that data and insert it into a SQL database. However, when the button is clicked those fields disappear because of the postback to the server. I also noticed that if a new number is selected in the dropdown menu, all the fields clear out as well. I know I would be pretty angry if I entered 40 some names and and needed to re-enter them all again just because I chose the wrong number initially on the page. So I know the code above needs a small tweak.
This is my first time working with control generation at run time, so I am a bit stumped on how to properly set this up.
I have 2 fields being displayed in a Gridview, StartTime, EndTime. I want to create a 'Time" column which shows the elapsed time in HH:MM format. (StartTime - EndTime) This was all generated with VS2008, table is pulled from an SQL Query.
I have a panel bar..each time I press panel bar item I display ascx control with in update panel..but it lakes update panel loading time lot..how I can decrease that loading time?
Recently i am develop a tuition center management systemNow i want to show a timetable which admin can view and know what time the class room is emptyMy timetable is : On the top of x-axis is time (8am, 9am, ...)On the left of y-axis is date (monday, tuesday, ...)In database i will define the start time and end time for each class
I have a Panel that is hidden to start with on one of my pages. But once a user posts data to the server, I make the Panel visible to display a success message. I do this by calling Panel1.Visible = true in the function I call for the data submission. I was wondering if there was any way to only display that Panel for a couple seconds by setting a delay or something so it doesnt just stay there until the page is refreshed or they navigate away.The code is below
I have a gridview within a panel. As I am using ASP Content, and the width of the grid view will auto extend to the left, and beyond the default IE width, and I got to scroll to left using the horizontal scroll bar.
Now, I wanted to fixed the length of the Panel to maybe 800px or 900px. With this I wanted to add a section to the Panel, and put the grid view within the section, and I wanted this section to have the ability to scroll horizontally.
In short, I do not want the Ie's scroll bar, instead, I want a scroll section within a Panel.
Here what i am trying to accomplish. I want to have a div or panel on the page and have some text on it. The div or panel must hava a specfied time limit and then disaaper from the page. Say i want this text to apper on 10Cotober 10.00 and disapper from the page on 11October 18.00.

how to suppress the "AM" in the gridview (template Bind("RideTimeMin", "{0:t}")? Don't tell me to use military time because the function is not "time on a clock"; it's how much time is allowed for a task (in this case the min/max hours & minutes that horses have to complete a 20 mile trail; e.g. 05:00, 05:27, etc). I'm currently accomplishing this in the "ondatabound" function by "..RTmin.Replace("AM","")". I have looked and looked at all the websites that talk about datetime formatting but have yet to find a way to do it upfront in the gridview bind statement.
In our application, we have a menu control that is bound by an xml file. This xml file will be created at run time based on the role/permission configuration. Of course, It is ideal to have this xml file created and lives in the memory. When a user log off or close the browser, its xml file is killed.
menuControl.Itemsource = "newlycreated.xml";
is the syntax to bind the xml file to menu control. I don't have an idea how to do it just yet.
I'm trying to create a user control class that extends Panel. Essentially, what I want to do is to have a panel that fires off an event whenever it's clicked upon.
So, I create something like this:
[Code]....
And then, in the ClickPanel.ascx.cs file:
[Code]....
I'm not exactly sure whether this would work as I haven't had the opportunity to test it yet.
The problem is that I can't have a class inherit from Panel. Creating a user control class requires that my class extend User Control - at least that's what the error messages have been saying up until now. The problem is that if I do extend it from the base class of UserControl then I lose all the functionality of the Panel itself and the entire thing is rendered pointless.
I have four collapsile panels. Now i want there sould be two link buttons expand all and collapse all. Now whenever user will click on expand all, all the collapsible panels should expand at the same time. Similarly, whenever user will click on collapse all, all the panels should be collapsed.
Im trying to make a web chat using ajax control tool kit. There is a script mannager, the update panel and the timer. I inserted the textbox for showing every text that is introduced by the users, the text for writing and the send button are out. It works great but if im writing some text in the exact moment of refreshing time (winch happends a lot because its every 3 sec) it does not let me write correctly cause the textbox kind of blink and you miss a letter. So, wich is the correct method for doing this without lossing the fluidity of the writing.

I am querying the SQL database table and returning the result on the webform with a repeater, but I need to display one record at a time and refresh with an update panel and timer to iterate through the rows of the table one at a time at a fixed interval.
Is there another solution to be able to display one record at a time using c# in the webform, but then cycke through the other records one at a time using a timer control and updatepanel?
I have a date/time stored in a smalldatetime field (ms sql 2005) that i want to compare with the current time and receive a difference. If the difference is less than 30 minutes, do this....if more do that....
