datagrid has a property called columns.. in that choose button column and choose edit,update and camcel... then go to the codebehind window and selet datagrid name in class name combo box and edit command in method name combo box.. then write this..

Private Sub dg_EditCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles dg.EditCommand
dg.EditItemIndex = e.Item.ItemIndex
Dim ds As DataSet = getdata()
bindgrid(ds)
End Sub
Public Function getdata() As DataSet
Try
con.Open()
ada = New OleDbDataAdapter("select * from topic", con)
ada.Fill(ds1)
Return ds1
Catch ex As Exception
Response.Write(ex.Message)
Finally
con.Close()
End Try
End Function
Public Function bindgrid(ByVal ds As DataSet)
dg.DataSource = ds
dg.DataBind()
End Function
this will automatically replace a texbox with the respective values

Printing Paper Size

I have a report setup to generate in legal size. I export my report to PDF, and it looks fine on the screen.

When I go to print it, the default is always shown in letter in the printer dialog. I have to manually change the paper size in the dialog box to "Legal". Once I do this, everything works fine.

Is there a way to ensure that if I am attempting to print a legal size report that this dialog will default to legal?

What you need to do is to read the ADO.NET[^] tutorials to see how to connect to DB and execute a simple query with a simple where clause to check this thing.

Masterpage and Content page

Ken.A10-Oct-06 15:02

10-Oct-06 15:02

Hi. Regarding the relation between a Masterpage and some Content page I believe that sometimes it´s a bit difficult to decide where is the best place (Master or Content page) to put a Control. For example, I have a set of menu items (from a Menu control) that are displayed as Tabs. Suppose I have only 3 menu items that I call AAA,BBB,CCC ... when I click in AAA it should call the A.aspx page, the BBB > B.aspx and CCC > C.aspx ... The Menu control is in the masterpage named Master.master and A.aspx, B.aspx and C.aspx use this master page. I can think of 2 alternatives when building this Menu Items:

1st > I set the url attribute like AAA > url="~/A.aspx" and similar to the other menu items ... so when I click in any of these menu items I´ll be directed to the respective url

or

2nd > I don´t use the url attribute and catch the OnMenuItemClick event and then create code to switch to the proper url

Since I´m using Tabs, it would be nice to set the 'Active or Selected' Tab after the user clicks it. In the 2nd approach I can set the e.Item.Selected = true; but the Css used to mark the selected item will not work because after the click, the current page will be redirected to the proper page and the selected item will not be selected anymore. So I´ll have to end up creating complex code just to mark the selected item, probably in the current page (A,B or C.aspx) referencing the Menu control in the master page.

I believe there is a simple approach to this situation. What is the best way to set the selected/active tab? This is not hard when using plain html pages, but this master/content page relation are a bit confusing ... I already read this interesting article: http://www.dotnetslackers.com/XML/re-27950_Capture_Master_Page_Events_in_Content_Pages_ASP_NET_2_0.aspx, but I think there must have a simple approach to this situation which unfortunately I just don´t get.

Because you go from the current page to a new one when a menu item is clicked, so the ViewState of the selected item gets lost, and IMO you may only need to write code in the Master Page to set the selected item of the menu control. All three pages use the same Master Page, so you don't need to write code to set the selected menu item in each web page. Another option might be that you can use a single web page instead of 3, and because you don't go to the new page so the selected menu item is persisted.

Ken.A10-Oct-06 22:41

10-Oct-06 22:41

Hi minhpc_bk,

You pointed 2 options:

1st: the one I´m using,eg navigating from current page to another, but with this option as you said, the ViewState of the selected item gets lost. What´s the solution for this option? Considering I want to navigate from one page to another ... Will I have to target the master page menu from each of the pages? That´s not a good solution ... too much coding

2nd: To use a single web page instead of 3, but this way I believe I´ll have to have views/panels hidden and showed according to the selected tab, right? This turn to concentrating too much logic in a single page. Suppose I have 100 tabs!!!

Because you define the menu control in the Master Page and all the web pages use this Master Page, so I think you only need to write code to set the selected menu item in the master page only and no need to do that from each content page. For example, you have 3 web pages A.aspx, B.aspx, C.aspx and the menu control in the master page is defined with 3 items accordingly. At run time you can detect the url of the current requested page by checking the Request object or SiteMap (if you define web.sitemap file), you then can set the Selected propety of the right menu item. The sample code to select the menu item in the master page looks something like:

//You can either use the Request object or SiteMap to determine
//the current url.
//string url = SiteMap.CurrentNode.Url;
string url = Request.Url.AbsoluteUri;

if (url.Contains("A.aspx"))
    Menu1.Items[0].Selected = true;
else if(url.Contains("B.aspx"))
    Menu1.Items[1].Selected  = true;
else
    Menu1.Items[2].Selected = true;

You're right, this option should only be used when you have just a few web pages.

In my masterpage code behind, where should I put the code above? I´m asking it because, when creating a menu I have basically 2 options: if I set prior the url for each menu item then I will not be able to use the OnMenuItemClick event, if I want to use that event I must secify menu items without the url and with the selectable attribute set to true. My menu is built using a custom sitemap provider and it renders like:

If the intention is to use OnMenuItemClick then the render code will be:

Using the option above I can make the selectable link like:

minhpc_bk11-Oct-06 16:19

The sample code is used to set the Selected property of an item in the Menu Items collection, and this collection is built based on data bound to it, so you can use this code when data is bound to the menu control or after that. And one of events that you can put the sample code in is the MenuItemDataBound which is fired after a MenuItem is databound and you can check this item is selected or not. The sample code looks something like.

protected void Menu2_MenuItemDataBound(object sender, MenuEventArgs e)
{
    string url = Request.Url.AbsoluteUri;
	//Here I simply compare the url of the current request 
	//with the Text property of the Menu item.
    e.Item.Selected = url.Contains(e.Item.Text);        
}

You mean you use the AspNet-Menu-Link AspNet-Menu-Selected stylesheet class to set the selected menu item? If so, once you can keep the selected item as it is with code, the style class will be applied.
