I am currently working on a signup sheet for new students. For each new student, we want add their schedule; therefore, I have a drop down list that displays the teachers which update another drop down list that displays the selection of the class the teacher teaches. The problem is that a student may have one or more classes, depending if they are in lower school or in upper school. The question is, how do add another row to the table and make sure it does not disappear when I select a teacher. Using jQuery, I successfully add the row with two new drop down list, but as soon as I select any of the teacher, the update panel refreshes and the new row disappears...
I have a master page which has some user controls within an update panel.I would like to put a property in this page to let the content pages to be able to enable/disable async postback way of working this page.Can I achieve it programmatically?
Here's what I want to accomplish: I have two .aspx pages, the first page with a ddl to select a vendor (SelectVendor.aspx), and one to add a vendor (NewVendor.aspx), if it's not in the first one. If a user adds a new vendor on the NewVendor.aspx page I want the page to automatically redirect back to SelectVendor.aspx and have the ddl automatically select the new vendor that was just added. Here's where I'm at so far: If a vendor is not listed in the ddl on SelectVendor.aspx, a user can click a button to navigate to a page to add a new vendor (NewVendor.aspx). On NewVendor.aspx the user types the name of the new vendor in a textbox and clicks an insert button to add the new vendor, then the page is automatically redirected back to SelectVendor.aspx with the new vendor name added to the QueryString. For example, let's say a user adds a vendor name "Best Vendor": The page is redirected back to SelectVendor.aspx as "SelectVendor.aspx ?vendor=Best Vendor"Now all I need from here is to have the ddl programmatically select the new vendor by the text value in the QueryString.
Here is the code that I'm having trouble with from my Page_Load routine for SelectVendor.aspx:
I am trying to programmatically set some lables inside a DetailsView that is populated by an ObjectDataSource. The detailsview is handled in an unusual way with one TemplateField that has one ItemTemplate that has one table that has two rows of significance and a boatload of bound items. I'll be working on the EditTemplate next. But now I need to set the top row lable values programmatically baised on the type of data that comes-up. I have scoured the Internet looking for ideas and found two possible approaches - neither worked. I get the error about something not being set to an instance of the object - or something like that.
Here is the ObjectDataSource:
[Code]....
Here is the DetailsView:
[Code]....
My first approach was to set the OnSelected property to the following code in the code behind, which executes:
[Code]....
My second approach was to delete that OnSelected property and try the following code in the code behind:
The problem is this: I am writing a system to show helptexts on certain labels. So in the PageLoad I recursively iterate all controls and save those with a certain tag. So far so good.
On the PreRenderComplete I iterate the controls and set their text property. The strange this is that the labels in ItemTemplate don't get the new text. The PreRenderComplete fires after the DataBound event of the gridview, the label gets found perfectly, in the end it has the new text, but in the page it's still the old text.
I hope I don't need the Row_Databinding event of the gridview, since I want to put all the functionality in an extender class with as little custom work as possible.
I am displaying a Modalpopup programmatically with todo_modalpopup.show() in serverside code. The Panel's Style is set to display:none.. But when I click on the target control id (which is inside the Grid) , the panel loads fully in the page itself and then displays the modal popup.
im trying to make a FAQs page, and i have some linkbuttons and some panels, what i tried to do was that, if for example someone clicked the link named "FAQ1Link" and i put its postbackurl to #FAQ1 and then i put the panels ID to FAQ1 i was hoping that even if the panel containing all the text for FAQ1 was to be at the very bottom of the page, the page would skip and select the FAQ1 panel with the text inside it.Any idea how to do this, i think im doing it wrong.
I have a text box and some validation on it. I want to make a panel visible only when
it is successfully validated,i.e.,textbox entry is valid.Also,I want to capture the entered valid value(it should be integer within 1-8) in a session,based on this number,I am going to add that many rows in an editable grid view.
I have an ajax tabcontainerpanel. What I would like to do is programatically change the text (header template text value) of one of the TabPanels (ID="TabPanel10B") depending on the selected option of a dropdownlist. Is this possible?
I have implemented master pages using this example How to implement a status bar in an ASP.NET application?. I have a property on my SiteMaster.cs inherited MasterPage called Environment. On my MasterPage.master I have this code:
<body> <form id="frmMaster" runat="server"> <.. some content removed for brevity ...> Environment: <%= this.Environment %> </form> </body>
What I would like to do is evaluate this.Environment and if it is "LIVE" then colour the background of this.Environment text red, and if it's "TEST" colour it yellow. How would I do this?
UPDATE I've just added this code to MasterPage.master
The page loads, but the text does not get set, it's blank! Also the old text, that was populated is now blank too (I left the old code there for now). I also get a warning in Visual Studio:
'ASP.masterpage_master.Page_Load(object, System.EventArgs)' hides inherited member SiteMaster.Page_Load(object, System.EventArgs)'. Use the new keyword if hiding was intended.
UPDATE2: This is what I have in SiteMaster.cs
using System; using System.Web.UI; public class SiteMaster : MasterPage { public string StatusText { get; set; } public string StatusTime { get; set; } public string Environment { get; set; } protected virtual void Page_Load(object sender, EventArgs e) { if (!this.IsPostBack) { if (Session["status"] != null) { this.StatusText = Session["status"].ToString(); this.StatusTime = Session["statusTime"].ToString(); } this.Environment = Session["environment"].ToString(); } } }
In my asp.net application, i have a grid. I am fiilling the data from through the text box then when i click on the submit button. the data will go to grid . But there is post back (page refresh is happning). So i want to avoid that page refresh by using the script manager and updata panel. My doubt is where i place the bellow code.
Where the grid ,textboxs and submit button will place in side the bellow tag or grid is enough to place over there or button and grid . and also we nee to place the bellow tag as seperatly for grid and submit button button
Note. - I am not placed my text boxs and submit button in side the gridview. But one update button is available inside the grid.

I have a text box to lookup codes. When you type search criteria in text box, it populates listbox and when you select item in listbox it populates the same text box with the value from listbox.
basically i am using same text box to search and finally populate it with the value. How can use update panel in this case so it doesn't refresh the entire page everytime list box is populated as well as when text box is finally updated.
I am calling a procedure in response to textbox_Changed event to poulate listbox.
i have update panel with some wierd ie 7 issue, when you click a a - z link on the below url, after the async postback the linkbuttons disapear until you mouse over, not sure why this is happening.
