|

unig bulid in function ==>
Private Sub dg_find_result_EditCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles dg_find_result.EditCommand
|
|

|

so good..........
suppose that your column index is 2(i.e. the second column).
then inside the dg_find_result_EditCommand, find your DropDownList, like this:
Dim DDL As DropDownList = CType(grdItem.Cells(0).Controls(1), dropdownlist), then write the code to bind your DropDownList.

when i write this code ==>
Me.dg_find_result.EditItemIndex = e.Item.ItemIndex
Dim DDL As DropDownList = CType(e.Item.FindControl("lst_temp_order_dir"), DropDownList)
DDL.Items.Add("gggggg")
Me.BindData()
Catch ex As Exception
Me.Literal1.Text = ex.Message
End Try
i get this error ==>
Object reference not set to an instance of an object.
=============================================================
and when i write this ==>
Try
Me.Literal1.Text = ""
Me.dg_find_result.EditItemIndex = e.Item.ItemIndex
Dim DDL As DropDownList = CType(e.Item.Controls(0), DropDownList)
DDL.Items.Add("gggggg")
Session("Edit_S") = e
Me.BindData()
Catch ex As Exception
Me.Literal1.Text = ex.Message
End Try
i get this error ==>
Specified cast is not valid
===============================================

Hi,
Can anybody guide me to a forum software in ASP or ASP.NET
which I can use without copyright issues and stuff? Like I
want to remove the logo, powered by etc. etc. and still not
get sued.
My requirements are pretty simple:
Lang: ASP/ASP.NET (doesn't matter)
DB: HAS TO BE MSSQL Server!!!
That's it.
This is a bit urgent. Please help.
ASP - AJAX is SEXY. PERIOD.

That's the drawback of ASP.NET - people don't learn HTML any more...
Use a regular form (not a runat="server" form), set method="post" and action to the url of the second page. Put some form fields in the form and submit the form.

I second that, too much abstraction at times. 
To answer the question, you could use a regular form and retrieve the posted data on the second page using Request.Form["textboxName"], as Guffa says. Alternatively, if you're using ASP.NET 2.0 you could use Cross-Page Posting instead, and keep everything with runat="server".
In your first page set the PostBackUrl property for your button like this...
<asp:TextBox runat="server" ID="txtMessage" /><br />
<asp:Button runat="server" ID="btnMyButton" PostBackUrl="SecondPage.aspx" Text="Click Me" />
...then in your SecondPage.aspx page...
protected void Page_Load(object sender, EventArgs e)<br />
{<br />
if(this.PreviousPage != null)<br />
{<br />
lblSomeLabel.Text = this.PreviousPage.Request.Form["txtMessage"];<br />
}<br />
}<br />
There's more to it though, do a search. If you're doing something relatively simple then it's probably better to use Guffa's approach.

Hey guys,
I just read abt the Image Element, i realised that once user click the image, the form will b submitted.

Hi..
I have problem with setting default button property on a page that has a clasical issue.
My page use a master page that has a textbox and imagebutton for search,
and the content page have a login button with two textbox for username and password. I put them in a asp:panel with giving the true defaultbutton property values. but always enter goes to search where ever it. The login controls is default are visible=false. I check on page load event that if the user has login or not, then open login controls to visible=true if needed. I have use asp:panel default value for several times but this times this don work. is there any think you know why could default button does not work?

All i want to do is to add a linkbutton to the datalist - done - and then connect it up so that when it is clicked it loads, in a separate window, a pdf. the choice of pdf depends on which 'record' in the datalist the linkbutton clicked is based.
the path will be something like 'uploaded_files/courses/' and then the file name. I have the file name as a field in fed into the datalist called (yes, predictable) 'file_name'.
I have tried all sorts of hints found on the web but it is beyond me. Could someone post some (simple) code and/or point me to a good tutorial to explain things in words of one syllable! The usual plea of a newbie.
cheers

Hi,
How do I go about manipulating the Response headers for an ASP.NET page? Specifically I want to change, or remove, the X-AspNet-Version and Server response headers. I've tried Response.AddHeader("X-AspNet-Version", ""), but it doesn't seem to work, the response header still shows X-AspNet-Version=2.0.50727. Any ideas? Thanks!
|

These are added by the server, not by ASP.NET. I think that the only way is to remove them in the settings for the web site.

It depends on if you were using Sql Express or standard sql versions.
If this is SQL Express you used to develop the site you may want to attach it to other Sql version like enterprise etc...

I am trying to construct "advanced serach" page where user can select choices from multiple dropdown lists and then when Search button is pressed the results are being displayed in a gridView. When I run the sproc below manually results are perfect, I can pass no parameter, 1 parameter or 2 . The output is correct in a standard SQL Query. For some reason in aspx the serach works only if 2 dropdownchoices are selected, I tried to select only 1 choice and search resulted in 0 rows. I believe problem lays somewhere in Default Value or pasing null. Can someone shed light on this problem. I need to be able to run this search for any dropdown list selected.
here is my G Wells sproc with coalesce:
ALTER proc sp_gwells
@DCSTANDALONE varchar(8000) = null,
@STAGE varchar(8000) = null
as
begin
select SERVER_NAME,[Team Member],DC/STANDALONE],SRM,STAGE,DECOMMSTATUS
from DecommMaster
where [DC/STANDALONE] = coalesce(@DCSTANDALONE,[DC/STANDALONE])
and STAGE = coalesce(@STAGE,STAGE)
end
