I need to perform some string manipulation to a columns contents in a GridView, and I'm using the DataBinding event for the template field for this. I'm converting all Environment.NewLine's to 's for outputting.
Here is the code:

It writes the correct, newly modified, string at the top - but why isn't it feeding back to the grid view?
I have a calendar on my page, i need to display certain information on the page once a date is selected. I have a procedure in SQl that returns 1 row with 3 columns. I need to display that data within my page in the labels.
Here is my code to return the values based on the selected date:
[Code]....
I tried this within my selectionchanged event for the calendar, but get error:
[Code]....
This is the error i get:
Compiler Error Message: CS1955: Non-invocable member 'System.Data.DataTable.Columns' cannot be used like a method.Source Error:
[Code]....
This is my code but nothing happens.
$(document).ready(function() {
var totalRows = $("#<%=GridView3.ClientID %> tr").length;
document.getElementById('Label6').InnerHTML = totalRows;
});
this is what i ended up using
var rqnum = $("#<%=GridView3.ClientID %> tr").length - 1;
document.getElementById('rqnum').innerHTML = rqnum;
var oknum = $("#<%=GridView4.ClientID %> tr").length - 1;
document.getElementById('oknum').innerHTML = oknum;
var xlnum = $("#<%=GridView5.ClientID %> tr").length - 1;
document.getElementById('xlnum').innerHTML = xlnum;
var dynum = $("#<%=datalist1.ClientID %> tr").length / 3;
document.getElementById('dynum').innerHTML = dynum;
this way it subtracts the header, however, how can i make it so if it is 0 dont subtract the -1 because i dont want negatives
I'm looking for a way to use custom ASP.NET validators to validate input, without using UpdatePanels, and without a full postback. The validators do several things - not just length/regex, but some other non-standard stuff as well. Javascript is required for our users, so I don't have to worry about normal users who have javascript turned off. I see several options, but none are ideal:
1) Suck it up and use UpdatePanels. I'm in the "UpdatePanels are evil" group, so I'd prefer not to do this.
2) Without using validation controls, manually validate the fields by passing the values to a PageMethod static method, via jQuery or any other AJAX framework. This would require client and server coding each time I needed to use a validator.
3) Use jQuery (or any other javascript framework) validation for client validation, then if they somehow get by that, have server-code validation controls for full postback. This would require all of the validation rules to be written in javascript as well as C#. I don't care about the full failed postback at this point, because the javascript validation would catch real users who weren't trying to screw me over.
Is there alternative out there for using real CustomValidator controls, with partial postback, C# code only, for validating input without UpdatePanels and without a lot of redundant javascript?
I have a page with 5 buttons on top. I want the area below the buttons to contain an update panel that will display button 1's panel if they click button 1. If they click on Button 2, then I want button 2's update panel to replace the button 1 update panel. Each panel has stuff on it like check boxes and text boxes.
Is there a way to do this? Is there a more efficient way to do this?
i have 3 update panels on the same page with labels that are showing different countdown and i want then to run separate from each other. I've tried to use timer control that triggers each of them separatley with limitations in ontick event., the coutdowns are strating but after a few seconds are stoping and i don't know why.i'm not using scripts. I want to run like those on mafia wars on Facebook when something is done to start one contdown and something else other timer.
View 3 RepliesI realise that there are many posts on update panels and repeaters but none that quite solve my problem. I have a page with two Repeaters each inside seperate update panels. They sit next to each other one on the left and one on the right. The left repeater is filled from my database on my page load event. Im am storing the data in a List<> and then binding the list to the repeater. This works correctly and displays all my results. Each item in the left repeat has a button aswell. The button needs toremove the data from the left repeater and place it in the right repeater. I only want the database to be accessed in the Page_Load and then never again during the use of the page, until the data is saved (I have not got to this feature yet). So I have decided to use List<> objects.
View 6 RepliesI'm using two update panels, and in the Page_Load, I'm calling if (masterPageScriptManager.IsInAsyncPostBack).Is there a way to test where the update came from and only refresh the affected panel?
View 1 RepliesI have a page that display a record set inside an update panel. There are also a handfull of checkboxes/textboxes that allow filters to be placed. Each checkbox/textbox is set as an async trigger for the update panel and set to autopostback.
If a single checkbox is clicked the whole filter/render process takes roughly 1.5s.
If I check a filter and then several more before the intial postback is complete I get a postback time of somewhere between 20-50s depending how many boxes I've clicked.
I notice (via firebug) when I check a box that triggers an async postback and than another box the original async post back is aborted. And yet it seems like it still executes (or maybe locks?) something on the server.
I have multiple update panels on a page. The page works perfectly in Chrome, Firefox, safari, and opera but it does not work in IE. I am using .NET 4.0.
View 1 Repliesi have 4 update panels, and 1 of them updates after a button has been clicked, and the other 3 panels contain other buttons, but what i would like to do is that, when the button is clicked, how would i make it ONLY trigger for that update panel, as it updates the whole page, and is affecting my Textbox on the page, which is also in an update panel. how i could make just that specific panel update, and not all of them?
View 2 RepliesI 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:

My first approach was to set the OnSelected property to the following code in the code behind, which executes:

Suddenly all update panels in my website became unknown elements. They work fine when I run site.
But:
no intellisense in update panel (no properties appear, no tags, like "triggers")
no ID property when I drag updatepanel from toolbox
VS says that I check if webconfig contains reference to System.Web.Extensions
But I have this reference already.
I have a web application which has several update panel this page is taking around 2 miniutes to process. Is it a problem with the IE 7
View 4 RepliesI have a Gridview containing 10 columns and anywhere from 10 to 40 rows and each cell contains either dropdown or input boxes.I also have a calendar control that changes the data displayed in the gridview.Right now I have an outer update panel around the entire gridview and then I have inner update panels around each control, so potentially 400 update panels depending on the amount of rows for each day.The individual control updates happen fairly quickly if I for example change a dropdown etc, but when I change the day and the entire gridview has to refresh it is painfully slow.On average 30-50% of the cells will be manipulated between change of date. What is best practise? Right now it is to slow.
View 2 RepliesI have two different repeater control which are in two different Update panel.I want to bind one Repeater value with another.But When i am using asyncPostBackTrigger or postbacktrigger it is reloading whole page.
I want to load only load update panel
I use four different update panels, that use the same timer as trigger.
1) Will the 4 update panels create 4 different HTTP requests to the server?
2) I'm using 4 different panels as the controls are located in different parts of the page, is there a way of putting them in the same update panel?
3) Is this a good coding practice?
For example, I have three UpdatePanels on the page. I click a button, and I get pretty long response, that contains all the data for the three UpdatePanels, the viewstate string.
I want to optimize my query and receive response like "ok" or "not ok". How can I do that?
I am going to outline my setup then where i am failing
UpdatePanel1 - Contents : 3 textboxes and AddButton
UpdatePanel2 - Contents : 1 GridView and SubmitButton
AddButton adds new row to DataTable with data from textboxes, binds DataTable to GridView SubmitButton sends data to database. The Adding of a row works to add the row to the gridview, but it won't add a second or third and so on, only adds the 1. SubmitButton belives the DataTable that GridView is databound to is null and won't send anything to the database. How can i get the datatable to persist between the two update panels? Do i use Sessions as my storage location? Page

I have a modalpopup control which has a gridview and search criteria. User selects a records and clicks modalpopup ok button ( which is set as modalpopup's okbutton). I have attached an event to okbutton click event. and inside this event, I am setting a label control which in on main page which called this modalpopup. I debugged code, it comes inside that event but doesnt set value. below is my event code.
protected void btnOkCustomers_Click(object sender, EventArgs e)
{
Int32 CustomerID = Convert.ToInt32(GridView2.SelectedDataKey.Value);
orders = new Orders();
DataSet CustomersDs = orders.GetCustomerById(CustomerID);
lblCustomerName.Text = "sadasdad"; // CustomersDs.Tables[0].Rows[0]["first_name"].ToString();
HyperLink2_ModalPopupExtender.Hide();
}
I'm having problems getting my label to update, it is a asp:label known as LabelFMI - what I am doing is when the user changes the value of certain things update it by either taking away or adding the difference. I've managed to get this to work by having to refresh the page and moving it to out of the function I made for it and into default.aspx's Page_load sub.. However I was hoping to not have to refresh to have it update? is there anyway to achieve this?
Code:
Private Sub UpdateLabels(ByVal start As Date, ByVal [end] As Date, ByVal value As Double)
'Import the data for the table
Dim da As New SqlDataAdapter("SELECT * FROM [event] WHERE NOT (([eventend] <= @start) OR ([eventstart] >= @end))", ConfigurationManager.ConnectionStrings("daypilot").ConnectionString)
da.SelectCommand.Parameters.AddWithValue("start", start)

How do I automatically update a Label.text (with javascript) ?
Anyone have this problem. When you write a ex. label name or label text in the properties window, it look like its updating the text before you actually are finish. This make you type over what you allready wrote. Its not a big problem,
View 2 RepliesI've got a single table, with project information and schedule information. To make the data easier to present, I created a tab control with two panels (a detailsview in each). The first tab is for project info, the second tab is for schedule info (again, all fields in the same table). The problem is, if i change info in both tabs, and then hit the update button, only the data from one tab is added to the table. I think this problem is simple to fix, and boils down to the way I have the page organized, but I can't quite figure it out.
I've boiled my code down to the following conceptualized structure:

When you click the update button, you return to the listview, but with only the information from your current tab saved. How can I get it to update from both detailsviews?
