I'm not sure if the topic describes my problem very well but I am creating some HTML elements (textboxes) on the fly with jQuery and I never know how many I will create (it loops through a database). I then want to get all the elements in the code behind and perform some actions (insert them into another database).
I know I can use
string n = String.Format("{0}", Request.Form["hiddenField0"]).ToString();
To get the first textbox but what if Idon't know how many textboxes I have created and want them all? Their name starts with hiddenField plus an incrementing number.
Is there a way to loop through all elements that has a name that starts with a certain string?
i have found out a way to find controls on content pages by using
var txt = $('input[id$=TextBox1]'). But how to access html elements like "<p>" tag and others in jquery when the html elements are in content page only.
I have two user controls that need to add a class atribute to the body tag of my page, however they currently over write one another if I just use
Body.Attributes.Add("class","value")
So I need to check if the class attribute exsists and if it already contains the value Im going to add.
If Not Body.Attributes("class").Contains("value") Then
Body.Attributes.add("class", Body.Attributes("class") + " " + "value")
End If
what string builder command do in the asp.net cs file.
View 4 RepliesI am using the code below (simplified for this example) to post data to a SharePoint list
StringBuilder customerDoc = new StringBuilder();
customerDoc.Append("<Method ID='1' Cmd='New'>");
customerDoc.Append("<Field Name='Name'>" + Name + "</Field>");
customerDoc.Append("<Field Name='Age'>" + age + "</Field>");
customerDoc.Append("<Field Name='City'>" + city + "</Field>");
customerDoc.Append("<Field Name='Country'>" + country + "</Field>");
customerDoc.Append("</Method>");
XmlDocument xDoc = new XmlDocument();
XmlElement xBatch = xDoc.CreateElement("Batch");
xBatch.SetAttribute("OnError", "Continue");
xBatch.InnerXml = sb_method.ToString();
XmlNode xn_return = sharePoint.listsObj.UpdateListItems(ConfigurationManager.AppSettings["SaveCustomer"].ToString(), xBatch);
As you can see I am using a stringbuilder which isn't ideal so I wonder what I should use instead to create an XML string?
SqlDataReader myreader;

sb.Append(myreader["DoseNumber"]);

sb.Append(myreader["Remark1"]);
sb.Append("<br/>");
}
lblDisplayDetails.Text = sb.ToString();
myreader.Close();
WHAT EXACTLY I WANT IS TO RETRIEVE DATA(may be from separate table) AND THEN DISPLAY THEM PUTTING SOME STYLE(font,color etc). Is retrieving from multiple table is possible in gridview ? I could use the DataReader, but how to display them in style(font,color etc)?
I have written such a code to loop through the records and build a string.
Is this s good idea or should I use repeater or something?

I need to display Name1 and Name2 in a single column in gridview. I am using Linq. How is this done.
View 2 RepliesI have a page that is used to add info from a gridview into a user's profile. I have explained my issues after all of the code. Here is the applicable code(s) involved:
Protected Sub AddToCart(ByVal sender As Object, ByVal e As CommandEventArgs)
For Each gvr In GridViewItems.Rows
Dim txtGiftAmt As TextBox = (CType(gvr.FindControl("txtGiftAmt"), TextBox))
If txtGiftAmt.Visible = True Then
Dim customPrice As String = txtGiftAmt.Text.ToString
'HERE is where I would like to set the new price variable value somehow

Response.Redirect("~/ShoppingCart.aspx")
End Sub
This sub is called by the following button when clicked:
[Code]....
Here is the sub from the ShoppongCart Class named AddCartItem:
[Code]....
Here is the problem that I am having: I have one specific item that allows user's to define their own price (for this item only). By putting this price in a session variable seems to be the easiest way to handle this (at least for me), but the session variable's value always "lags behind". By this I mean that the first time the items is entered, it uses the default value of cartItem.ItemPrice. The second time the same item is added (with the intention of a different price), this new item's cartItem.ItemPrice is set
as the first session("customPrice").
Because the user is selecting his/her own price for this item, I am not worried about lack of security involved with using query string to pass this price, but I can't get the string passed to the ShoppingCart class correctly (shows up null). Is there a way to append this customPrice to the current page's query string before the Response.Redirect takes place? If I understand this correctly, the Response portion "posts back" to the current page before the Redirect sends us on our merry way, right?
How can I control on HTML elements by using C# code in asp.net pages.

I am trying to write a linq query that will retrieve all the ID's from any asp tag. Also, the query needs to group everything together alphabetically. So for the example above, the linq query should return "lbl1", followed by "lbl2", followed by "txt1", and finally "txt2". Notice it did not grab the "bodyID" because it was not part of an ASP.NET tag. Is there an easy way to do this? I am using C#, by the way.
I recently designed my own user control.
My control consists of an ASP:Tree control and a plain HTML text input with copious Javascript, jQuery, and .net code to bring them to life together.
I have two issues.
1) I can only have one instance of this control on a page at a time. The text input is named txtUserControl, so putting a second instance on the page causes a name collision. I have the same issue with the ASP:Tree.
2) If I put my user control inside an ASP:UpdatePanel, it does not work at all. I get errors all over the page when I try to refresh it. Incidently, I have this same issue with a user control created by one of my co-workers.
I have some ideas for controls that I would like to be able to use again and again in my projects. I would like them to be rock-solid.
I have some simple code in an aspx page
<object width="550" height="400">
<param name="movie" value='XXXX' />
<embed src='XXXX' width="350" height="370"></embed>

I want to be able to dynamically set the value of XXXX.
