Web Forms :: Changing The Value Of An "Input" Field Dynamically From Code Behind File
Jan 16, 2011
I have this in my code-behind file (VB.NET):
[Code]....
Here is the HTML source of the part of the page:
[Code]....
Where that comment in the code-behind file says "REFERENCE IN CODE HERE", that is where I want to set the value of the "remLen3" input (client-side control) to "30 characters left."I obviously left out irrelevant things like inserting the txtNewComment.Text into the database. But what's going on here is when the user types in something into the txtNewComment text box, I'm using javascript to change the value of the remLen3 control.My problem is that when I submit the text from the txtNewComment textbox to the database and set the txtNewComment.Text equal to Nothing, I don't know how to reset the remLen3 field value back to saying "30 characters left.". I already tried to add a "runat="server"tag to it, but when typing stuff into my txtNewComment textbox it gives me an error. I already tried to figure out what the error meant, so I'm not going to spend time trying to solve it anymore; I would rather just see if there is a workaround to using the runat="server" tag. Maybe do some kind of a CType(FETCH_REM_LEM3_HERE_SOMEHOW, INPUT_TEXT_TYPE??).value = "30 characters left". If there is a way of converting the input text control (remLen3) that way, then how would that be done? I just want to change the value of that field when the server-side button is pushed.

I have a code behind file which has only a few placeholders and literal. The gridview control and others are added in real time according to program conditions. I noticed that once in a while th eprogram stopped working because the .aspx file is changed and some of the place holders disappeared - Why? (the bolded lines disappeared once in a while)

What I need to do is perform some kind of decision statement and when true I need to change the backcolor of a treenode to grey, so that it has a grey box around the whole text. There is no backcolor property for the tree node and I don't need it applied all the time so I don't think a CSS class will do this.

Scenario: I have a form with 3 input fields (text1, text2, text3). Is there a method to capture these fields in the aspx file of a second webform? I think you have to use someting like <%= %> but I'm not sure.Idon't want to use the code behind file because the number of input fields is dynamic

I have a DetailsView on the page and I have made one of the fields a TemplateField. In the EditItemTemplate and InsertItemTemplate I have a DropdownList that is databound to a table in my Sql Server database. I wanted to add an initial value to the DropdownList
namely "- select -" .
I set the AppendDataBoundItems property to true and added the initial value as a ListItem.Markup of the DropdownList
<asp:DropDownList ID="DropDownList_HP" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_HP" [code]...
This works fine for new input. The problem is however that the database already has records that were entered through a Windows Application and many of these records has a null value in this field and exceptions are thrown when I tried to open these records
and the system tried to set the SelectedValue of the DropdownList.After some more searching I found this help
http://msdn.microsoft.com/en-us/library/ms366709.aspx
So I changed the ListItem in the DropDownList markup to the following:
<asp:DropDownList ID="DropDownList_RefHospDV4" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_RefHosp" [code]...
This now solved the problem of opening a record where the value is null in the database, BUT now the RequiredFieldValidator is not validating anymore to make sure that a databound item is selected for this field and not the initial value "- select -". So basically now it is not checking anymore to see if valid input has been entered for the DropDownList and it accepts "- select -" thus it acts as if the field is not a required field anymore.
In short what is required is that I want to make sure that the user enters a valid selection in the DropDownList, but it must also cater for old records that do not have this field entered yet so that those old records can be opened in the DetailsView .Opening Old records (with null in that field):When these old records are opened in the DetailsView the DropDownlist should show "- select -" when the value in the database is null.
Saving records (old or new records):When saving the record in Insert mode or Update mode the RequiredFieldValidator should show that a valid input is not selected if the DropDownList is still on "- select -".

Precisely and concisely, I have aspx page that has only one button "Generate". If the user clicked on this button, one HTML page should be created.
The created HTML page should have title "Home" and the Body should contain "Hello World".
1) What is the code that should be written inside "Generate" button in order to accomplish this functionality?
2) Assuming the HTML page gets created, How to store it inside specific folder on the local drive? Or how to store it inside DB?

I have an ASP.net page with two textboxes where the user types in input. I applied a requiredfieldvalidator to both textboxes as well. However, I also want the textboxes to change to a backcolor of red if the form is invalid when the user clicks the button to submit the input. I tried this code below in tthe button click event, but doesnt work...
If Page.IsValid = False Then
txtCosts.BackColor = Drawing.Color.Red
txtRevenue.BackColor = Drawing.Color.Red
End If
How else can I change the Backcolor of the textboxes when the input is invalid.......

I have static html paypal buynow button that works great, but it's static.
[Code]....
But it is possible to change the values for the hidden inputs from .net codebehind code? I found this post which takes a different approach of sending these hidden fields instead as a query string to paypal. Not sure I like that though as would this not possiby explose some of those fields like the return page?
http://www.makaistudio.com/mksBlog/post/ASPNet-and-Paypal-buy-now-button-Offer-discount-at-checkout-in-code-behind.aspx
Basically what id like to do change the important parts of the button and info I'm sending to make it dynamic.I know I can do something like this in the markup, but that would mean having to fetch data mulitple times was hoping I could somehow adderss the field values directly in the codebehind. Or possibly dynaically generate and insert the entire changing input type fields from the codebehind
<input type="hidden" name="invoice" value="<%= getinvoice()%>">
Possible to add them with something like this: myform.Attirbutes.Add (???). If so how do I contruct these input types in .net?As far as return logic security, I've tested that it's solid, i just need to automate the button process so I don't have to create a buy now page and button for each product.

This may be a simple question but here it goes. I have an insert form that captures the current date of entry. What I would like to do is not cause the user to enter or select the current date but have it display on page load and capture to the field in the table on submit.I am rather new to ASP and am using Visual Web Studio 2008.

We have a database with around 5000 records in it. We also have a web page that displays many of the fields. One field is an nText field and displays up to several paragraphs. My customer wants me to add those A+ and A- buttons for increasing and decreasing the font size for this field. My problem is that many of the older records have quite a bit of formatting in the field. Most of the rest contain styles dictating a font size of 12 px. Is there a way to increase and decrease the font soze of the text without modifying all the records?
Here's an example:

I've got a details view control on a page. One of the columns, from the database table, is a bit field. It is not nullable, and that's the way it has to be. Also, in most cases, when inserting data, it will be true (1) be default. I've found in testing, when inserting data, that it was false, for some reason. So, I changed the column to a template field and went to the InsertItemTemplate for that column, and changed the checkbox Checked property to True, instead of the default False. However, it has really screwed up the page because now it won't save anything at all! When I try saving something using the details view, it does show the checkbox as being checked, but man, once I try saving it I get an error message back from the database saying that the column doesn't allow for nulls.
Huh??? How in heck can the column on the page have a value (it is checked), but when it goes to save something it fails? Furthermore, before I converted this field to a template field, it worked perfectly. I tested several other insertions, and they all worked. But when I converted it to a template field, it stopped working? What's that about? I even tried setting the default value for the Checked property of the checkbox back to False, but that still doesn't work, it still wants to pass in a null. What's going on here? Why is it that converting a field to a template field, which was working perfectly fine before I made the convension, stop it from working at all?
