<asp:ImageButton ID="imgBtnReview" ImageUrl="~/images/agt_reload.png" runat="server" Visible="false" CommandName="Review" CommandArgument='<%#Eval("id")%>' />

I know the back button always presents a problem, but this one doesn't make any sense.
I have a simple details view and a button on a page. The button sends the user to the homepage. I am trying to prevent the user from being able to use the detailsview if they click Back in their browser.
This is the button click event
[code]....
When the button is clicked...oddly the user is sent to the homepage then when they click the browser back button they are sent to previous page with the detailsview still visiible.
I know I am missing something, can someone fill me in?
Why is the detailsview still visible?
I have 3 image button in my page
1- Imgabout_Click
2- Imgpro_Click

According to code when i click each of these image button some label visibility be true or false i don't have any problem with
1- Imgabout_Click
2- Imgpro_Click there is problem with
3- Imgcontact_Click
When I click on imgcontact_Click it lblcall.Visible = true; and I can see lblcall(this is label) in my page after that i click on Imgpro_Click or -Imgabout_Click when I click these 2 image button lblcall.Visible = false until now every thing work correctly but when i click on imgcontact_Click again it should lblcall.Visible = true again but it didn't
I mean when I click on this image button i can't see lblcall in my page i think it didn't do lblcall.Visible = true it happened when i click this image button for second time why?

View 10 RepliesI have a Panel that I'm setting visible=true explicitly. The debugger passes over that line and visible still evaluates to False on the next line. Obviously as a result, the Panel is not shown. How is this possible?

I have a panel that contains several controls.
On the other hand i have a MultiView that contains Several view that in turn itself contains several controls .
In multiview we have to set ActiveViewIndex for the view which we want to see.
That same thing can be done through Panel containing another seleral panel's and setting its Visible property to True/False accordingly.
Is seems Multiview is just using this Visible property internally to render controls .Since other views (whose Index is not set to be active Index) are processed on the server for its Whole life cycle(I am confused here..whether i am right or not) .Same thing perhaps happen when we use a Panel insteed and use Visible=True/False. So, what is the difference between MultiView and Panel taking this scenario ?
I have a master/detail page using a gridview as the master, and a detailsview as the details. The gridview is set to select a record, and the detailsview picks up the ID and you can either edit that record, or add a new one.The detailsview is set up with various template fields, and if everything on the page is visible, it works OK.However, I wanted to hide the Gridview when the user in working with the detailsview. But if I do that, the detailsview doesn't update the record.
View 2 Repliesi have a gridview inside a div that has scrollbars. see bellow
[Code]....
is there a way to keep the gridview header always visible while scrolling down.
like in MS Excel.
I am able to get the values of GridView cells when the columns are not visible.
For Example:
<asp:BoundField DataField="TemplateKey" Visible="false"/>
foreach (GridViewRow gvrow in GridView1.Rows)
{
gvrow.Cells[0].Text.ToString()
}
But if I make the BiundFiled Visible="true" then I get the value in the code behind.
I do not want to show this value to the user and also want to get the value in the code behind. How can I do that?
Whenever you turn off the visibility of a column in Gridview, on Edit, the value becomes null because its never bound. The only way I know of stopping this behavoir is to put it in the DataKeyName list. Is there any other way to prevent this? I have quite a few columns that will not be displayed in this "release" but I want there for future extensibility. Also, in some cases these values will be used for calculations but the user should not see them. Is there no toggle property for "non-visible" items to remain "unchanged" or something of the sort?

Hi I have a situation where I want to set the initial visible property of an Image to False and then in my code change it to True and then run a sub routine. My problem is that no matter how I order the code the sub runs before the image becomes visible. When I debug the image only becomes visible when it hits End Sub. Is there any way around this? Here's my code:

I am just trying to view gridview that is inside other gridview but it is not visible although its visible = trure.
Here is the code:
[Code]....
<asp:ButtonField Text="Void" ButtonType="Link" CommandName="Void" />
' RowCommand
Dim f_iIndex As Integer = Convert.ToInt32(e.CommandArgument)
Dim f_oSelectedRow As GridViewRow = grdMeterCorrection.Rows(f_iIndex)
Dim f_oCertIdCell As TableCell = f_oSelectedRow.Cells(11)
Dim f_sCertId As String = f_oCertIdCell.Text.Trim
If e.CommandName.ToLower = "void" Then
Dim f_bVoidRet As Boolean = VoidCert(f_sCertId)
End If
The problem is the CertId field in the GridView has visible set to false. I think this makes the value unaccessable to the RowCommand.
I have a Gridview with some template columns. Inside one of the columns, I have a ImageButton with a serverSide OnClick handler to show or hide a panel. And all the panels by default are hidden. What happens is that when I click the imageButton the first time the panel gets displayed, but if I click the same button, on the same row again, - where the panel is now visible - the panel doesn't hide itself. Here's what happens when the imageButton is clicked:
protected
void ImageButton1_Click(object sender,
ImageClickEventArgs e)
{
ImageButton imgBt = (ImageButton)sender;
Panel compRecDetails = (Panel)imgBt.NamingContainer.FindControl("CompanyRecDetailsPanel");
if (compRecDetails.Visible ==
false)
compRecDetails = true;
else
if (compRecDetails.Visible ==
true)...............................
