Re: how to restrict from browser

10-Jul-08 21:07

Many of the user have the same Issue with there Browser Back and Forward button.
Issue here is not the browser but your implimentation. you need to take care of logout and login functionality
1. Clear out the DataContainer or session when user says Log Off.
2. you should check for user crendetial in every page Load
Like Session or DataContainer is having the values or not if no value redirect user to Login Page.(Better way is to write this functionality in base class load function instead of every Page).
3. Now even user says log out and Click back button browser will show the page from its Cache.it is not coming from server so even if he is able to see the Page if he clicks on any server side event he is going to Login page.

Please let me know if you have impplemented then also facing some different issue ?

Thanks and Regards

Wats the better way,which one u consider as a base class?
My problem is,
After login,did some operations in some page and from that page if he clicks on back(browsers)button,it will go till homepage and with FORWARD button it is just allowing to do anything where i was doing something---which is wrong.
So this user credentials,am i need to check on each page??Ya how to redirect to login page as i am not emptying session values other than logout page?

How to open a crystal report in a new window?

10-Jul-08 23:40

You can't control it as user can click any thing in its browser.
If the user is Logged in User and he clicks back button can go to any last page visited.
The main thing is that if user logged out and then click back button and if comes to any last page visited then he should not be able to do anything.

If don't want to have back functionality just disable the cache of the browser then also i don't thing it will help you.

Logged in user can navigate the website using back button you can check this here in CP just click back back you can see your last page visited and do anything as you visited it first time

This won't open in a new window. Try the following one

string url = "ReportViewer.aspx?ReportName=" + "rptCostByTaskLevel" + "&ReportFormat=" + format;
ClientScript.RegisterClientScriptBlock(this.GetType(),"NewWindow",
            string.Format("window.open (\"{0}\",\"mywindow\")",url),true);

Make the hidden field run at server. In the second page, use "PreviousPage" property and find the control. Something like

TextBox text = this.PreviousPage.FindControl("TextBox1") as TextBox;
if (text != null)
   // use text here

Replace the texbox name with a valid one.

Look at how tree view emits JS to toggle the visibility. Use the same and register it on the node's click.

N a v a n e e t h10-Jul-08 19:23

10-Jul-08 19:23

I am sorry, my last reply was wrong. Here is how you do that.

1 - Goto tree view properties, choose "Nodes".
2 - Choose one node, and in the properties, make "SelectAction" to "Expand".

You are done.

DataList in Gridview

Hi, I have the complex business object like: Ownership. Ownership object is collection of buisness objects, collection of person objects.

class Ownership

{

Collection<BusinessData> Businesses;

Collection<PersonData> Persons;

}

In the ASPX.cs Page_Load I am adding the business objects to Ownership object:

OwnerShip owners = new OwnerShip();

owners.Businesses.Add(new BusinessData("XX LLC", true, 0, 20, "pres", "", true)); XX LLC is business name.

owners.Businesses.Add(new BusinessData("YY LLP", false, 0, 20, "vice president", "", true));

In ASPx page it is like this:

<asp:GridView ID="gvOwners" runat="server" AutoGenerateColumns="False" Width="787px"

OnRowDataBound="gvOwners_RowDataBound">

<Columns>

<asp:TemplateField>

<ItemTemplate>

<asp:DataList ID="BusinessPersonDataList" runat="server">

<ItemTemplate>

<%# ((BusinessDescriptionData)Container.DataItem).BusinessName %>

</ItemTemplate>

</asp:DataList>

</ItemTemplate>

</asp:TemplateField>

</Columns>

</asp:GridView>

Now in the RowDatabound event of GridView, I want to bind one DataList with Business colection.(in another DataList I want to bind the Persons collection, I did not put the code for this part yet. First I am trying with the Busienss objects).

The RowDataBound event is like trhe below:

protected void gvOwners_RowDataBound(object sender, GridViewRowEventArgs e)

{

OwnerShip os = null;

GridViewRow r = e.Row;

if (r.DataItem != null) // Make sure we're not in the Header or Footer row

{

os = r.DataItem as OwnerShip;

}

DataList BPDataList = e.Row.FindControl("BusinessPersonDataList") as DataList;

if (BPDataList != null && os != null)

{

BPDataList.DataSource = os.Businesses;

BPDataList.DataBind();

}

}

When I run the page, I am not getting any results. The Gridview is not displaying anything. If I remove the RowDatabound event and in the page_load gvOwners.DataSource = owners.Businesses; I have not used the datalist in this example, just binded to one Label in Gridview. Then it is displaying the results.

I think the RowDatabound event is not firing. What is the problem in the above?

Thanks in advance.

You need to put break points and step into the code to know what's going wrong.

You do not understand

I want to set the width of the list that drops down seperately
from the width of the control

So it displays all text

Sandeep Akhare10-Jul-08 23:27

10-Jul-08 23:27

Still not understing the issue
Do you mean that drop down is having some options whose text is more than the width of control ? beacuse of it user can't see the whole text of the list ?

Thanks and Regards
