Forms Data Controls :: Back Button Doesn't Go Back When Canceling / Updating Edits In Gridview?
Mar 31, 2010
I have a gridview bound to a sqldatasource with editing enabled. If I click Edit, then either Cancel or Update, the update or cancel occurs and the Edit button reappears. However, I cannot then click the browser's back button without having the Update and Cancel buttons reappear. A second click of the back button takes me to a state where the Edit button shows again, *then* another back button click will take me to the referring page (the one before the one with the gridview on it.) IOW, it looks like the postbacks are cached. How can I prevent this and have the back button go straight to the referring page?

I have a dropdown list with sessions: Summer, fall, spring, summer Interim.
And also have a gridview to display hours of those sessions. When chose session from dropdown it displays the data related to gridview.
Gridview has the 'Edit' option to edit hours for each sessions:
[Code]....
When I edit let say spring and update the field it redirects me to main page but everytime it selects the data from summer).
What I want is? If choose Fall from dropdown and make edit(in editpage.aspx?id=..) and update the data, then it should redirect to main page but choose the Fall from the dropdown (Not summer)

I am trying to see if it possible to create a back button that goes back 3 pages and refreshes that page. The make up of my page is a little complex. The Home page has a password prompt that enables a multiview to be visible with a gridview of information. The gridview has a details link that has a 2 querystrings that gets sent to the details page. The details page has the ability to be edited and updated. this is why I wanted it to go back 3 pages. The code I am using to go back is
<asp:Button ID="Button2" runat="server" CausesValidation="False" OnClientClick="javascript:history.go(-3);return false;" Text="Back" UseSubmitBehavior="False" />

I have a gridview that does a select statement against a sql database, there is not editing, inserting or deleting just the select statement. What I want to do is have the data in the gridview refresh upon either hitting the back button or the forward button.
If the back button is pressed it should give me yesterdays data from the table. If I hit the forward button it should give me tomorrows data, at the same time i want the forward button to be limited to going forward only 5 days from todays date.
I figure that I have to do this in a Updatepanel however I am unsure as to how to do this.

Neither updating data or turning back to ItemTemplate.
Here is its code:

Here's an odd one that I've never seen before. Only on IIS, not in Cassini but in all web browsers I have a button that posts back and the page_load event fires, but the actual button click event doesn't fire. there is no re-writing of the page or anything else happening.

I've created a Sign Out link on my page, just like the one you see on the top right hand corner of this forum.
This is the code i use :
<asp:HyperLink NavigateUrl="~/Login.aspx" ID="hypSignOut" runat="server" Text="Sign Out"></asp:HyperLink>
However, after signing out, I click the back button on my browser, I can still go back into the site. How do I prevent this?

Before I go the route of using hidden fields or something similar, is there any way to send back to the server changes to the disabled state of an ASP.net Button control? I have a Button that is initially enabled and I disable it via jQuery on the client. Works great. The only problem is when I do a PostBack the server still thinks the Button is enabled and sends back a response that changes it back to enabled. Why doesn't the ViewState send back the current disabled status of the Button? Is there a way to force it to postback the changes? Other ASP.net controls, like the CheckBox, do send back the state changes to the server. Seems odd to me.

I have a Default(contains the sign-out button) and Login page, once the user is not authenticated, it will always redirect the user to login page.
So the scenario is when the user hit the sign-out button it will redirect him to the login page which is good. My problem is, when the user hits theprevious or back button from the login page,it will still read the authorization cookies and redirect him to the default page. which should not be the case. the user should be redirected to login page when authentication is invalid.
I've read some solutions on the net, but still it doesn't work for me. below are the codes I've used for my sign-out function
[Code]....
By the way, when the user is authenticated, the previous or back button is available/enable for the user.

Being new to ASP.NET I have run into trouble building my own Whack-a-mole program. I think my problem comes from using Buttons, which by themselves send post backs to the server, making the software unusable. The looks are in place, making new buttons show up in the grid, in different places by random. However, when a button is pushed - the score doesn't change (which I feel is strange).
Not so strange is that the Button doesn't work since it sends post back to the server - reloading the UpdatePanel. I think I should use a different controller like the CheckBox and style it hard using CSS (which isn't a problem). Is this the correct way to go, or should I make use of JavaScript AJAX instead?
Note to self: This technique shouldn't be used in a public application since it put too much unwanted pressure on the web server.

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 want to make sure I go about this in an efficient manner. I have a gridview. On the gridview, I have some columns that are read only values . These values go through calculations based on values in a database. The stored procedure takes information in the database, does some simply calculations (this value * that value / another value type of stuff) then returns a recordset as a datasource for the grid.
Other columns on the gridview have values the users can enter data. I want to be able to provide a recalculate button that will run calculations based on the entered values which will change the readonly values and then repopulate the gridview's read only values without going back to the database. This recalculate button is not the save to the database button. The save to the database button will take the values in the user entered columns and save them to the database. Then, the next time the grid is called, the page calls to the database and loads the grid.
So, what I'm looking to do is allows for recalculations on a gridview, a gridview with about 24 columns and about 1000 rows. My first thought is to create a class that reads the gridview and then applies the business rules, then updates the gridview some how. Or, maybe have a dataset table thats i read the value from the user inputs, then apply business rules and then bind the gridview to the dataset table. Do any of you have thoughts here, maybe have done something like this?

I have three identical procedures that are all used to open the contents of a GridView into Excel. One was working fine but the other two were getting a 'RegisterForEventValidation can only be called during Render();' error when attempting to run the form.RenderControl(html) command. The only difference I saw was that the one that was working had the allowsorting value set to 'False' where the other two were set to 'True'. I set the other two to false and they worked. So what is going on here? Why would this cause the error; is the GridView somehow doing a post back and loosing settings when this value is set?

Is there a way I ignore all gridviews events (sorting, paginating) when using the back command (history.back)?
For example:
The user is sorting my grid and when he presses the back button or a link with history.back he goes to the previous page, not the previous grid state.
Im not using ajax or update panel, Im not allowed to. It's a regular grid in an aspx.
