Page Has Not Refreshed And Hidden Control Contains Value From The Previous Submit?
Dec 23, 2010
Some say it is not a bug it is default in asp.net. but for me it is a bug in logic. When you say refresh it should be reload the component that you are refreshing. But in asp.net i notice that they recalling all activity and viewstate like event and data that are triggered in the previous postback. My opinion it is a redo not refresh. this is only my observation on the issue dont hate me on this microsoft fan.
I have a user control which has a gridview with hidden fields in some of the template columns. The grid columns are created and bound by code dynamically in each postback and not in design mode. The gridview is placed in an update panel. In my aspx page where i use the user control , there is a dropdown which fires postback and based on the selected value of the dropdown the grid data gets filtered. The dropdown in aspx is not part of any update panel.
After the postback of dropdown, the grid data gets filtered and the grid is rebound with fresh values. The values in the controls like label, button or link button are bound correctly. But the values in the hidden fields are not refreshed and always points to the values of the rows that was generated before the postback of the page (initial page load).
I'm using a wizard control with 4 steps, when I use the previous button to navigate back to the previous step the page reloads but at the bottom of the page.Instead of showning the whole of the page, the user views the footer of the site and the previous button and next button.I'm sure there is a very simple answer to this but I just can't figure out how to get the page to reload to the top.
I have an ASP.NET application designed for a Windows CE device that needs to take in information from a scanned barcode. The device sends the scanned data as string input with a crlf to whatever field has focus. I set up my page with a textbox that takes the input and posts back to look up the item.
Now, I'd like that box to not be visible to the user, but IE complains when I set focus to it if the field is "visibility: hidden" or "display: none". I've tried moving it off screen using absolute coordinates, but setting the focus scrolls the window to the new location.
How can I build a query in a new page using the value from a prevous pages control's value. I can transfer the value to the new page, I just don't know how to use the passed value to build a query. I want to populate a data grid filtering with values obtained from the proveous page.
I am developing a web application in ASP.NET3.5 with C#. I also using Telerik RadAjax Control. When user click the menu then open the page with a new tab(Like web Browser).I want to create, when user back any previous tab(page) the will be show the previous data without loading 2nd time( like browser tab). Is it Possible ?
The code was working correctly until i used a master page.
R.aspx vb Code: Dim athUsr As New AuthenticateUser() athUsr.IsLogIn("~/Login.aspx") If (IsPostBack = False) Then Dim objcoll As UserRegistrationColl objcoll = UserRegistrationProvider.GetDynamic(Nothing, "UserId='" + SessionManager.UserId.ToString + "'", Nothing) [code]...
So I have my login and password txtboxes in the master page header, When I click on login button it should hide those boxes and display something else.But everytime I navigate to another content page they get visible again. What it the best solution to keep them hidden while the user is logged in?
Inside Page2.aspx file I'm trying to access Textbox1 control which is defined in Page1.aspx file but it gives error because it cannot find the control. The statement PreviousPage.FindControl("TextBox1") works only if Page1.aspx file is not tied to a master page. How can I find the control when both Page1.aspx and Page2.aspx files are part of the master page as shown below?
I have a custom listbox control intern it has "hidden input server control".and i want assign values to that hidden control.That custom control is in table which runs at server.When i try to find hidden control using Page.Findcontrol and <tblserver>.findcontrol it is returing with null.Can you please help on this.
Note: If i use Request["HiddenCtrl"] am gettting values,but i want assign values to that control.
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.
I am using the file upload control in my page i upload image .. path available in the file upload control after i selected the drop downlist for different action at that file upload control path refreshed.. wht shoul i do?
I have an asp UpdatePanel, an asp panel, an asp timer, and an asp label on my web page, as you know the whole idea of updatepanel is trying to implementing partial page rendering mechanisem, however, it is not the case in my scenario, here is the code:
and on the pageload event, i assign:
strangely, the labl1 does update the time without causing the whole page post back, but the panel does cause the whole page refreshed, and the asp panel contains asp buttons and those buttons are generated dynamically by code behand c# file, am i missing sth here or the nature of asp:panel will cause the whole page post back?
I have tweaked some button colors on a webform after updating those pages on server where iis is.From my local machine i can see the updated colors of button.But in some of the other users machines they still see the old webform.even though they refresh there IE.but when they use firefox they can see the new changes.What is wrong with IE, even after deleting cache still it is showing old webform.
I have a Reportviewer control linked to Report1.rdlc with a matrix with Drillthrough activiated.When I click the "+" buttons to drill through, even I enclosed the control with Penal etc it still caused the whole page refreshed which is annoying. The same Panel code works well on other ASP.net controls on page on running.
