C# - Web Forms Stopped Remembering Previously Entered Values?
Nov 28, 2010
I have one question regarding browser remembering previously entered values. I'm developing ASP.NET MVC 2 application and for some reason my web site suddenly stopped remembering previously entered values in text inputs. I can still see values entered yesterday, but non from today.
I also noticed that my username textbox values started appearing in email textbox although I never changed the name or id of my html elements. The only thing I did was to remove some input elements and added some new... But they all have unique id's and names...
I did a lot of search over the web, but just couldn't find the right answer...
Would it be possible that the model binding could be causing this which I implemented today? Or maybe some web.config configuration?
I am working on asp.net mvc using linq to sql. I have to login my application only if the user registered (in register view page).I need to know how to compare the entered login and password values with registered values
i have 20 Textboxes i am not sure what did i touch by i normally dont play with VS Settings i dont understand. So those textbox are normally defined like this
I want to compare a user-entered value on a Web form against an array of existing values from the database, and do so on blur. If match, then show error. Scenario is to stop user from needlessly filling out other fields if this record has already been entered.
how to trigger this? What parts are client-side, what parts are server-side? Can I do it without Javascript?
i have a datagrid. which display some values which is already inserted and that is fetched from database.but from the datagrid i need to insert the values to database. how to find in which row a new record get inserted and to pass all the values to database
How to get the row before last row index or any identification..
I am having a "TextBox" a "Label" and a "Button" in my aspx page. If I enter some values into the textbox, then that value should be displayed in the label...and again I enter some values in the same text box, that value should be displayed without disturbing the first value and so on...
I have a page with some controls and a next button. When the entered information does not match the database values, an error message is displayed.
After seeing the error message, the user enters correct data and clicks next. The code behind the next button makes the error message empty and invisible and goes
to the next page. On the next page the user clicks the browser's back button. The previous page is displayed with the valid data and the error message showing.
I had expected the error message not to be displayed.
I have a detailsview data control connected to a datasource. i converted all the bound fields to item templates and they have all been converted to textboxes. i need to compare values entered in one textbox and output the value in the other. I have attached a snippet of the code below. but its not working.
've got a website that's written in php and I'm attempting to re-create it in ASP.NET, so far I think I'm doing well with the help of this great community. How can I carry over pre-existing redirects in ASP.NET? Is there some kind of file that I can store them all in, that gets read?
I am selecting multiple dates on a calendar control ,, and then i insert them into DB. The problem happens after i insert, if i want to add new list of dates, once i start selecting on calendar all last selected dates appear (get selected on calendar) Does this mean these dates are saved in Session or what? Here is the code I am using:
I am using a FormView control. The allows me to update records in the database. However, when a database field is null I can not update the field on the form. It works fine when the field is not a null value. I am not using any code behind (C#) to bind the data or manipulate the data.
I have read that when there is a null value in the database thatthere is no record in the "dataset". Can anyone show me how to bind a value in the form when there is a null value previously.
I have DropDownList, which has some options to choose from. Now after when user selects one of the options, it has to click on a button, which is a redirection on the same page:
I have to use redirection instead of postback, because I use flot which is javascript library and all the code has to be written again when user selects some other option. The problem is, when it redirects back, for some reason I can't make it to remember the value in the DropDownList, which has user previously selected. I tried this with this code:
The problem is, if for example user selects Dewpoint from DropDownList and then clicks on a button, which causes redirection, the new url should have:
Graphs.aspx?Selection=Dewpoint&...
but instead, it says:
Graphs.aspx?Selection=TemperatureOUT&...
Now if I remove that code from Page_Load it works, but it does not remember what has user selected before. Now I know that there has to be something with Page_Load. Isn't that when page is redirected, the Page_Load get's called, so it should look a the Selection value and print it out. So it has to be a problem with redirection, that for some reason does not set the selected value.
Is there a way of getting the current column being used to sort a table on an rdlc report ?I'd like a way of remembering how the user sorted the table so they dont have to reset it every time they open the form.I know I could make them use an on screen control (eg dropdown list) to change the sorting and then capture the choice as the report is loaded.But I'd rather do it in the background I can.
I've got an ASPX page set up that loads and displays dynamic data from a local SQLite database. Since the data is being written to the database from a separate C# application, I've set up my ASPX page to refresh every 30 seconds when the database has flagged itself as actively receiving new data.
On my ASPX page, I've got a TabContainer with several different TabPanels that each represent a different view of the data. Now, when my page is being refreshed, the active tab panel is being reset to the one set in my ASPX page as the ActiveTabIndex.
I was wondering if there is an easy way to persist which tab is being remembered.

I use an objectdatasource programmatically to use a parameterless method when SearchWord variable is empty and a Search method with one parameter when SearchWord is not empty, the event I use is objectdatasource selecting so that I can adjust parameters conveniently, I have a problem here: I can add a new parameter and set its value but I can't remove a previously added parameter from objectdatasource selectparameters and an error raises because of this, this is the selecting method:
[Code]....
Both adding and removing the search parameter takes place in this method while adding works removing the added one Not works.

I have a web app that allows users to upload images. Last week, all was well. This week, it appears the code is breaking. Here is the code:
Protected Sub btnUpload_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnUpload.Click If FileUploadControl.HasFile Then Dim month As String = ddlMonth5.SelectedValue Dim year As String = ddlYear7.SelectedValue ' Dim whatis As String = FileUploadControl.PostedFile.ContentType Try If (FileUploadControl.PostedFile.ContentType = "image/jpeg") Or (FileUploadControl.PostedFile.ContentType = "image/pjpeg") Or (FileUploadControl.PostedFile.ContentType = "image/gif") Or (FileUploadControl.PostedFile.ContentType = "image/x-png") Then Dim fs = New FileStream(FileUploadControl.PostedFile.FileName, FileMode.Open, FileAccess.Read) 'save file with new size Using image As System.Drawing.Image = System.Drawing.Image.FromStream(fs) Using bitmap As New Bitmap(image) bitmap.Save("C:WebsitesimagesCusRespData.jpg", image.RawFormat) bitmap.Save("C:Websitesimages" & month & year & "CusRespData.jpg", image.RawFormat) End Using End Using StatusLabel.Text = "Upload status: File uploaded!" fs.Close() fs = Nothing Else StatusLabel.Text = "Upload status: Only .jpg,.jpeg,.gif and .png files are accepted!" End If Catch ex As Exception StatusLabel.Text = "Upload status: The file could not be uploaded. The following error occured: " & ex.Message End Try StatusLabel.Visible = True End If End Sub
On the development side, I see this error: The file could not be uploaded. The following error occurred: Could not find a part of the path. On the production side, this occurs: The following error occured: A generic error occurred in GDI+.
