Web Forms :: Store Selected Index Of Listbox In Hidden Field And Then Return To That Value On Postback?
Jan 4, 2011I must be doing something wrong, but this makes sense to me. I have a Listbox loaded with tons of items from a datasource. A user clicks one of these items it grabs the selectedindex (an integer) and stores it in a HiddenField (works fine).
Now when the page does a complete a refresh (after postback) I want the ListBox to go back to that selectedindex that is in the HiddenField. Problem is, it seems that after postback the HiddenField is empty? Then I thought about storing the value in an Integer variable in code, but that is simply coming up as a zero at all times.
Question 1: What is the best/simplest way to do this?
Question 2: How?
I am currently grabbing it on selectedindex change

State Management :: Hidden Field Value In User Control / Make The Hidden Field Save Its Value?
Mar 23, 2011I have a custom user control which contains a asp hiddenfield object. The value of this hidden field is being set using javascript and I have verified that the value is being set properly. When a postback occurs the new value is not being saved and I cannot access it in my code.
I believe the problem is because the user control is not saved in viewstate and therefore the hidden field value is not saved accross postback. How can I make the hidden field save its value? I tried accessing it from the early page cycles and still no luck.

Forms Data Controls :: Grid View - Can't Get The Value Of An Hidden Field's Footer Row
Dec 3, 2010I can't get this to work:
I have a grid view with several TemplateFields. A couple of them are set to Visible=False; each template field has an EditItemTemplate, an ItemTemplate and a FooterTemplate.
[Code]....
While in GridView_RowUpdating event, the value bounded to the EditItemTemplate is properly read
[Code]....
so, debugging ttbImp.Text = "4"; But when trying to get the value bounded to the FooterTemplate, the label contains no values.
[Code]....
so, while debugging, lblImp.Text = "";
why that? I believe it has to do with the hidden visibility of the field, but I can't understand why it reads the value inEditItemTemplate, and it doesn't in FooterTemplate.
Data Controls :: Post TextBox And Hidden Field Values To Another Page
May 7, 2015I have a hidden value field on a page. On submit I post to a different page. On the page I've posted to I do a Request.Form but I do not get the value just a null value. This is the initial page
<div id="booking_content_wrapper">
<form id="mainForm" name="mainForm" runat="server" action="Cancellation.aspx">
<h2>
Paid Bookings</h2>
<table cellpadding="0" cellspacing="0" border="0" id="booking_table">
<tr>
[code].....
The javascript ViewCancellation function is set to a hyperlink in the code behind. The function will have a value like this,<a href="#" onclick=" View Cancellation(54666);return false;">cancel</a>.
string sResID = "";
protected void Page_Load(object sender, EventArgs e) {
HttpContext context = HttpContext.Current;
sResID = context.Request.Form["ResID"] != null ? context.Request.Form["ResID"] : "";
sResID = Regex.Replace(sResID, "/[^A-Z]d-/g", "");
context.Response.Write(sResID);
}

View 1 RepliesForms Data Controls :: Escape Apostrophe When Binding To Hidden Field In Gridview?
Apr 15, 2010I've got a gridview with a hidden field, i'm trying to set a value as follows:
value='<%# DataBinder.Eval(Container.DataItem, "Name")%>'
which works in most cases except when the name has an apostrophe like O'Neil. I need to escape the ' if possible.
so i tried: value='<%# DataBinder.Eval(Container.DataItem, "Name").ToString().Replace("'", " /' ")%>' and
value='<%# DataBinder.Eval(Container.DataItem, "Name").ToString().Replace("'", " //' ")%>'
which doesn't work because of the final apostrophe in the notation i.e. %>' It truncates after the word e.g O'Neil Someone becomes O' which is incorrect.
This works like a charm: value='<%# DataBinder.Eval(Container.DataItem, "Name").ToString().Replace("'", "'")%>' which isn't good practice as I don't want to hardcode '

View 8 RepliesDataSource Controls :: System.Data.Datatable Updating SQL Server Image Field
Jul 1, 2010I have a datatable for which i'm defining a dataadapter. I'm specifying an updatecommand with sqlparameters for the dataadapter I set the updatecommand's parameters using the following overload:
[Code]....
The length 16 is used because this is the length of the field according to sql (the image datafield is a pointer of size 16) I noticed .Net is actually truncating the string because of the length i'm setting. An image of size 3kb will properly upload if we set the length field to be greater than 3kb The question I have is what is the proper value (or strategy) to use in order to set for the length field so that ALL images will properly update to the database, with each using the appropriate size.
I guess i could theoretically set the length to be maxint, but this seems sloppy. Looking at sqlparameter documentation i didnt see an 'unlimited' or 'default' length i could set, which would allow each update statement called to use the appropriate size for the data length for that row.
C# - Passing JSON Serialized Data Via Hidden Field?
Mar 2, 2011In ASP.NET WebForms I want to pass arbitrary data from server to client and back again. I am serializing to JSON and have been simply producing JavaScript that creates the object on the client. I have no problem sending data to the server with ajax, but there are situations where I also want to send a Javascript object data back to the server on postbacks. So I guess it needs to be in a hidden field.
1) What is the best way to do this in terms of minimizing complexity and optimizing space and efficiency? In researching this I discovered Protocol Buffers but there does not seem to be a good C# implementation. I did find one, but it was a couple years old and self-described as buggy so that scared me.
2) If I just pass a JSON string, how can I be sure it will be safe to include as the value for a hidden field? Is there any reason I might not want to do this? I could Base64 encode, but it seems like this adds a lot of overhead. What is considered the best or preferred method?
Javascript - Hidden Field Data Lost On Postback
Nov 18, 2010I am working on an ASP.NET application (well supposed to be deploying it about 3 days ago) and my hidden fields are loosing value when the form gets posted back..
I am using them to store information i write using javascript and on my own machine this works fine but as soon as i deploy it on our server everything else works except these values are lost..
I am using the .NET AJAX control toolkit on the same page and have noticed my calander datepicker also looses the data..
I have checked using firebug and the data is definitely getting post to the server but is getting lost somewhere!
State Management :: Passing Data Client To Server Using Hidden Field

Forms Data Controls :: Store Format Or Format Output Of Text Field Into Datalist
Mar 29, 2011I have a text field that users enter information into a database (SQL Server). They are entering as little as a few sentances to multiple paragraphs. I can successfully display the data on my webpage, but the text field is not formatted very nicely. The output is all smashed together like one big paragraph. Ironically, when I also display the text as a tool tip it outputs as multiple paragraphs like it was entered. How can I format the output in the datalist to create a more readable text field? My datalist field is as follows:
<asp:Label id="WebDescriptionLabel" runat="server" Text='<%# Eval("WebDescription") %>' ForeColor="Brown" />
