Web Forms :: Clear Cached Data Form Fields Like TextBox
Sep 23, 2012
I have one issue on my localhost running website that is when i submit data from asp.net form . it don't clear the data permanentaly from the page history.like , i submit one record and after this one i double click on the textfields the previous values are shown ?
i am using html input fields for inserting data to db e.g.:
<input type="text" runat="server" ClientIDMode="Static" id="StreetNo" class="form-control input-mask-phone"/> and a submit button for submitting all data :
also i am using an update panel to trigger this button click event ( to avoid postbacks and page refreshing ) . i want to clear out all my fields after submition of data , but it won't happens , even i tried on submit_click's event also , i did :
/// after submittion StreetNo.Value = string.Empty;
I have a form containing 7 fields and I want that when i press submit button all the fields are cleared how can i do this? In my form when i click submit fields not clear until I refresh.
HTML has an input button type to reset all fields in a form to their initial state in one step: <input type="reset" ... />.
Is there a similar simple way to reset all form fields of an aspx page from code-behind? Or is it necessary to reset all controls one by one with TextBox1.Text=string.Empty, TextBox2.Text=string.Empty, etc. ?
Update:
Context is a simple Contact/"Send us a message" page with 8 asp:TextBoxes on the page (where the user enters the name, address, phone, email, message, etc.). Then he clicks on submit, the Onclick message handler in code-behind sends an email to some administrator, and all the form fields the user filled in should be emptied and he gets a notification in a label ("Message sent blabla..."). I want to have the form fields cleared to avoid that the user clicks again on submit and the same message is sent a second time.
I am using the SqlSiteMapProvider to build my Sitemap ... but I'm guessing that this question is valid for any type of site map.
There's a very specific instance where I need to rebuild the sitemap because the user completes a task and I need the Sitemap to rebuild to reflect that. I don't want to get rid of the natural caching that comes with the Sitemap stuff so I'm wondering if there's some way I can clear the cached map just when this certain task gets completed.
Is there some [Sitemap].clear() type method I can run for this?
I have a combobox that is used as a control for Formview, so when the user selects a name from the combobox the data in formview displays in edit mode. However, some if the data that is displayed in formview needs to be empty. For example if the Date is being pulled in, it needs to be empty or null in edit mode.
I am caching a file in ttpContext.Current.Application object. Now when I change the values in file, it does not get reflected in the application (I am reading the values from the file for app version).
Even after restarting the app pool and the website in IIS, the changes does not reflect. I dont want to restart IIS.
I am having two hidden fields which are server controls and i set the values in the javascript function. But i want to clear them as soon as one of my code behind method gets updated. As my page is not refreshing the hidden fields are not getting cleared. But i dont want page refresh.
So how do i clear the hidden field values without refreshing the page.
I'm new to JQuery and recently started using the validation plug-in. I have a scenario where user have one of those type in your password and confirm your password textboxes. This is easilly accomplished with the "equalTo" rule how every my requirement is that once this failed the error message should be displayed and the textbox cleared. I assume there is no short and easy way todo this without writing javascript functions. point me in the right direction with a url or example.
Then a question to all you JQuery experts I've noticed "digits" and "number" to me they do the same thing? If not then explain the differance to me. Also how do I do a validation group in jQuery, similar to the asp.net validation controls assigned to a group and activated by a certain valodation enabled button?

I have a relatively complex dataset (numerous tables, some with multiple records) generated from reading in an XML file. I need to connect said dataset fields to an ASP form. At the moment I'm assigning them manually, like so in the pageload:
I did some looking into binding the textboxes (and dropdownlists, and checkboxes, and and and...) directly, but it seemed to be too many formats to use.
So this works fine, but as the number of fields increases, those load and unload lists are going to get unwieldy.
just starting strongly typed data sets, I have managed to fill my data set and bind the gridview, but now I dont understand where to map the fields ? Inside the business logic layer or presentation layer.
working example to map fields with a select query and with an update .
I have a gridview that pops up when you click a link. It displays 5 columns.. if you click on the "select" link next to the record, i pass that rows values back to my form and submit the form again.. this works fine if i select a record that has all my form field values..
but if i pick a record that has some values that are empty it doesnt work.. after debugging im finding that for the fields that are blank on the screen, this is the value being passed " " which of course is not empty or null.. so my code doesnt know how to handle that.. i even tried to add .Trim() to the end of the gridview value and still getting that space being passed. How can i pass empty string instead of the for fields that dont have anything to pass?
This is my code i have for the SelectedIndexChanging event of the gridview
I have a contact form inside of an update panel so I don't get the page flicker. Once the form passes validation and the email sends, how do I automatically clear the text boxes?
I have a Contact page, with 4 textboxes and 4 field validators. I made a RESET button to clear the text when pressed. But for an example: if i type on 2 textboxes and then press the RESET button, it tries to validate all 4 textboxes.
I have one dropdownlist and textbox which is databinded and will display retrieved data on a listbox, i wanted to clear the textbox and dropdownlist using a button after displaying data on the listbox.
I have a gridview to which I'm adding template fields programmatically. Each of the template fields have a textbox. I would like to make this text box have 2-way binding to a database column. see below code.
[Code]....
I'm calling the above class as follows

How can I make the text box such that when I edit the text, this change is reflected in the database as well?
I have a gridview that have 5 columns. The first column is the select button, 2nd to the 4th are just displaying of data which I have used HTMLdecode to set it to disable the htmlencode so that I could display 2 lines in the gridview. However, after enabling htmldecode. my 2 fields, the select button and the text box columns are not able to be displayed out.
Here is the code for the gridview:
Protected Sub gvTransaction_RowDataBound1(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gvTransaction.RowDataBound If e.Row.RowType = DataControlRowType.DataRow Then Dim cells As TableCellCollection = e.Row.Cells ' cells For Each cell As TableCell In cells cell.Text = Server.HtmlDecode(cell.Text) Next End If End Sub
I have a gridview which sources information dynamically from database.Here when i go for the default "AllowSorting" flag equal to true, i am able to achieve sorting of all displayed columns except the textBox control column whose values refreshes to zero.
This is the basic question , but I am not sure how the HTML data is handled when submitted through any registration form.
Consider I am having a Registration form where I am entering new customer. And while entring the details of customer I have put some HTML data into the textboxes(simple textboxes ) provided for. Show should I handle this.
