i have formview which i populate with some data that coming i store inside class, inside the form view there are two textbox controls that are "hardcoded" inside the FV markup and an ASP Table:
[Code]....
its all work fine, but once i press on the update button inside the formview the page get reloaded with the two "hardcoded" controls that in the markup but all the controls that i added during run-time are no longer there!
i can see them in the form collection but they not visible in the page.
I have a DataGrid that has a dropdown list in an ItemTemplate. Basically, users select a value from the dropdown for each row of the datagrid. When the page is posted back, the selected index of the dropdown list is always reset to 0, and the items are re-bound.
Does anyone know why this might happend? The dropdown items are hardcoded, so there is no external data binding that happens on post back.
I have a Formview that is bound to an SQL database, and in its item template I have added an image button.
That image button on selection needs to postback a primary key Value (VoucherID) to be used in a second control on the same page. In VWD I can get it to post back but I can't get it to post back with the VoucherID parameter.
I can easily get it to send a querystring parameter, but I don't want to do it this way.
However, once the update is finished (and I call e.Cancel = true), the LoginView control does not databind its children... so they are all blank. The FormView's viewstate is still fine, as all the rest of the controls outside of the LoginView appear fine. I even handle the FormView_DataBound event and a Trace shows that the FormView is being databound on postback.
Why then is the LoginView not keeping its ViewState/being databound? Here's a sample code snippet showing the flow:
i have the following scenario: one formview. when in editmode there is a child formview linked to the other by a column value. i need to take the value of one of the values of parent formview controls and set it to a textbox of child formview in insert mode. I wish to know which event should I use in codebehind to bind both controls? (that escenario will have paging and must keep the binding as if it was master detail)
Background:I'm building a custom control as a base class that derives from CompositeControl. It consists of a FormView, a ObjectDataSource and a CRUD-Button Series (Create, Read, Update, Delete - Buttons). I'm loading the different FormView templates within the deriving classes dynamically from file with Page.LoadTemplate().
Class structure:
TabControlBase:CompositeControl
Employer:TabControlBase
Applicant:TabControlBase
Each deriving class knows the specific template-paths for loading FormViews templates.
The ObjectDataSource is connected with a DAL using a Select and an Update Method. The Select-Method works fine: When loading the CompositeControl the data of the DAL are shown in the Labels of the embedded FormView (ReadOnly-Template). When I'm switching to Edit Mode the data also are displayed in the TextBoxes (Edit-Template).
The problem occurs when I'm trying to update data using the "Save" - Button: The connected DAL-Method is calling properly, but the parameters all are NULL.Tree structure of this custom control:
All controls will be added dynamically in the base class "TabControlBase" within the overridden CreateChildControls - method. The CreateChildControls method is called by the deriving classes e.g. Employer after setting specific properties e.g. templates, object data source methods etc.The control is placed in a simple abc.aspx-Page. What I detected so far on PostBack
- When I'm looking at the ViewState Collection within the OnLoad-method of the abc.aspx the ViewState-Collection is Null (Count = 0)
- It seems that the control tree is empty. I'm not able to find any control using a proper working recursive FindControlMethod
- Only the Page.Request Collection shows the expected controls
Conclusion for now:It seems that the CompositeControl "forgets" the values of the FormView TextBoxes on PostBack. It seems it has to do with ViewState Management.
In an vwd2005 aspx page, I have a formview, dropdownlist and 2 sqldatasources. My markup is below
[Code]....
When the dropdownlist causes the postback, the formview does not display the data (it's there, I've double checked using query analyzer). Also, the OnIndexChanged only makes a button visible and has nothing to do with the data. What am I missing?
I have a formview that use the formview iteminserted event. The information inserts into the formview fine, but all cells blank out after the insert. How can I make it so I can show all the values I have inserted show up in the formview after the inteminserted event?
I have a page with a FormView on it. The page is strictly for adding records to a Table. I have the FormView bound to an EntityDataSource and everything works greate except for one thing.
I want to initialize a date field in the FormView to today's date. So, in my page_load event I have:
if (!Page.IsPostBack) { //Initialize SetupDate to today. TextBox setupdate = (TextBox)fvJob.FindControl("txtSetupDate"); setupdate.Text = DateTime.Now.ToShortDateString(); }
The first time this page loads, the txtSetupDate field is initialized.
Although, and subsequent loads of the page doesn't initialize the Text Box. I step through the code in the debugger and I can see that the code is executig, but something (the FormView bind?) is "clearing" the Text Box.
I have a formview that I am adding and editing items. I need to have a lookup button besides a textbox so I can click the button and show a webgrid listing items with their descriptions. Select one and enter the data in the formview control. I know how to put the data in the formview control with the FormView.FindControl method. But how can I add a lookup? Can I do this with a popup panel? And on the postback update the textbox control?
I would like to ask if it is possible to access data on a master FormView from a nested detail FormView.
I have a main form (master) with several tabs (detail) and would like to display a label with text from main form that is hidden by the tab at the moment of editting. My asp page looks like this.
[Code]....
Is it possible to get the value of the label CompanyTextLabel from CompanyTextBox using just ASP.NET expressions or something similar without writing c# code in .cs file?
am having two textboxes and a label in a gridview control, i am adding a javascript function to the second textbox onblur event attribute and display the result in the label, the function works fine and result is displayed in the label, but when i am saving the grid data into the database, the label is returned 0 or empty, but i am able to see the value , how to overcome this.
I have an aspx page that loads a static graphic and put session strings in it. I used Image1.Save(Server.MapPath("gen_img2.jpg"), ImageFormat.Jpeg), but it's not saved on the server. I thought this was a user permission problem, so I assigned the ASPNET account write permission to the folder, and it still doesn't work. Did I use the wrong account? I use winserver 2003 and IIS 6.
I have a text field into which I'm saving order details, using LINQ to SQL.
Each order may have a different number of columns, depending on the type of order, so I thought I'd just create a single structure to take care of everything, and display details in tab delimited columns.
The text is created properly prior to saving to database:
[Code]....
However, when stored in the database, the spacing is no longer maintained.
i am having problems with an asp.net c# site whereby i am setting a session state object to true and then redirecting to another page that needs to check the value of the session state object and it is null.
Sometimes it is set correctly and other times is is simply null.
When i debug on my local machine it works perfectly every time. Only when i upload to my web server does this temperamental behaviour happen.
As it is based around the security of the site it is obviously important that the session data be valid and accurate every time.
Is session state data unreliable?
AFAIK its set to inproc, cookieless, 30 min timeout, vanilla installation of IIS.
Does anyone have any suggestions? Perhaps i need to thread.sleep inbetween the storing of the session data and the reading?
NB: the time between the write and the read is about 70ms.. ample time for the data to be written to RAM.....
i let the user to edit and save the pdf file How to do this is there any api from adobe for controlling pdf file in asp.net web page can i have some sample codes
I write the following code but there is an error. I just want to retrive the image which I have save into tha database from the sql server and to display in the picture Box(image)
I don't believe the built-in membership saves username in session, does it? If I'm not mistaken it's saved in a cookie.I've implemented the ImageManager add-on for tinyMCE and trying to set the default folder for images based on authenticated user's username. Looks like out of the box, ImageManager allows this by getting the username from session.
I am converting my datetime object with current date and specific time 23:59:59 as shown underneath.
[Code]....
But when I check in my sql table datetime column, it is changes seconds part of time from 59 to 00, so for instance, if I have a datetime, 2010-08-11 23:59:59, it changes this to 2010-08-11 23:59:00. How should I fix this.
In the following code i want to save the value selected by user from drop downlist into database. but whatever value is selected by user, first value is saved to database
