ASP.NET 1.1 don't have a GridView control. Do you mean DataGrid ? DataGrid can maintain it's controls state if viewstate is turned on. It will do this automatically. Make sure you are binding the grid in not ispostback block.

All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia

Yes it is a Datagrid only. If I do in the Binding in the Not isPostBack event, then the Paging is not working

You need to bind the grid again after changing the page number

I do like this

Private Sub dgResources_PageIndexChanged(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridPageChangedEventArgs) Handles dgResources.PageIndexChanged
        dgResources.CurrentPageIndex = e.NewPageIndex
        dgResources.DataBind()
    End Sub

But is not maintaing its state.

Bye the way I am using this code to check whether the check box is checke / uncheked.Even the checkbox is check it is giving the value Checked = False always

For i = 0 To dgResources.Items.Count - 1
            chk = (dgResources.Items(i).Cells(0).FindControl("chkResource_First"))
            If Not chk Is Nothing Then
                If chk.Checked = True Then  ' Always false.
                      'Do some thing 
                End If
            Else
            End If
        Next

You are not setting the data source.

What is the problem you are having in looping through the rows or columns of the datagrid. You can always get the row or count of the datagrid and then loop through with that.

You can't hide dropdownlist items. You should only populate the control with items that the user has permission to select.

Iterate through client side code using JavaScript

Hi,

I have 26 tags in my page repersenting an alphabet. I would like to iterate through these controls using Javascript during runtime and determine which Anchor tag was clicked in one function. Is that possible using Javascript? I tried to do this by iterating Page.Controls collection in my .cs file, but it dint return any tag ids, though I had runat="server" for each of them.

Regards,
Blumen

You can do this in JavaScript. Use the window.alert() method.

Opening empty e-mail in user's mail client

Manny Castillo16-Jan-08 12:29

Hi,

I want to be able to open a new e-mail message with the recipients filled in. Currently I'm doing this by using a "mailto:a;b;c;d;etc;" link which I build up dynamically. However, when this exceeds 4096 characters the link just stops, which is understandable since that is probably the maximum amount it can take. Building an entire mail form using the .NET mail object isn't an option though.

Basically the need I have is just a simple way to open up an empty e-mail in the user's standard e-mail client with recipients dynamically filled in (preferably BCC ofcourse). Is there any way to go about that without running into size restrictions when the amount of recipients is quite big?

Cheers,

-Manny

Dropdownlist then open a new page [modified]

I know this should be possible
I have a dropdownlist. In it I have the name of multiple .aspx pages
I want my user to select a page and have that page open. I also would like to pass 2 variables to the page they opened to be used in a query statement eg CustID and dateofpurchase. These are located in the page with the dropdownlist (source Page) as text in 2 textboxes hidden. I am looking for a code in the dropdown selected event that could open the page and pass these into the target page. PLEASE I WOULD BE MOST GREAT FULL. I am using VB with asp.net. I have tried both response.redirect, server.transfare and even coded the source page into the target page with little success because I do not know the correct syntax.

Fine I will Just answer it myself. Make the dropdownlist, The id of your list item is the name of the page (ie .aspx). The text is the name you want to show in the list. Now since the page with the dropdownlist is the main page use all the other pages to obtain the controll that you want using the ctype(previouspage.find controll),textbox). There you have it when you select an item the correct page opens and has the controll info you need. As for me I use this to open each system to allow my users to change the systems using the information on two controlls in the main page. The controlls Identify the owner of those systems. Hope it helps someone else.
