How to create events for dynamically generated datagrid

BalasahebK23-Jun-06 4:37

23-Jun-06 4:37

I don't want to drag and drop datagrid from tools, but I just want to create it during runtime using vb.net syntax on asp.net page using asp.net 1.1 version. ASP.NET 2003.

dim dg as datagrid

then adding bound column by creating its object. It is fine upto this level. Even it gets implemented. But I couldn't find any article that helps in generating events for RUNTIME GENERATED DATAGRID. So can anybody help in this regard. I would like to implement events like PageIndexChanged, SortCommand, ItemDataBound. So please help in this regard.

I'm using VS.NET 2005, but it should be similar:

DataGrid myDataGrid = new DataGrid();
myDataGrid.PageIndexChanged += new DataGridPageChangedEventHandler(myDataGrid_PageIndexChanged);
...

protected void myDataGrid_PageIndexChanged(object sender, EventArgs e)
{
....
}

Thanks for ur help
But ur code doesn't work after converting in vb.net means like this

dim dg as new datagrid()

dg.pageindexchanged event is not available.

Does I need to import some file?

Wht should I do now?

I think I need to add RaiseEvent as event bcoz when I write
dg.pageindexchanged
It gives me error saying 'dg.pageindexchanged is a event and cannot be called directly. Use RaiseEvent statement'

Can u suggent me on this event? Smile | :)

Sorry, I didn't notice you are using vb.
I don't know exact syntax for handling events in vb, but this is what I found on msdn:[^]

'----------------------------------------------
Visual Basic (Usage)

Dim instance As DataGrid
Dim handler As DataGridPageChangedEventHandler

AddHandler instance.PageIndexChanged, handler
'----------------------------------------------

This code is not supposed to raise event, but assign event handler to event. Event is raised automaticly when you change page of datagrid by clicking it.

I hope it helps

Give a man a fish and you feed him for a day. Teach a man to fish and you feed him for a lifetime.

Give a man some code and you solve his problem today. Teach a man to code and you solve his problems for a lifetime.

By giving suggestions and links to documentation Guffa is teaching you how to think. If he just straight gave the code then people would just copy and paste the code and never really understand how it works. So what happens is that they come back and ask for more and more code. I've seen it several times when I answer the same person over and over with pretty much the same question with a minor modification. If they'd read the docs rather than just copy the code they wouldn't need to keep asking pretty much the same question over and over and over and over and over and over and over and over and ove and over and over and over... Well... you get the idea.... I hope.

It has been just 3 and a half hours since you replied to minhpc_bk - He might be asleep, shopping, visiting family, any number of other things that mean he has not yet seen your response. HAVE PATIENCE!!! Sigh | :sigh:

If your problem is really that urgent that you are trying to embarrass those that try to help you in to giving you more assistance as a priority then I suggest that you can get help from Microsoft Support. They will be glad to hand-hold you right through your problem for a small fee. The people here give up their time for free in order to help their peers. A little more appreciation of their dedication to helping solve other people's problems would be nice. Remember that they don't have to help you, and if they didn't you wouldn't get anywhere at all.

Access client io ports

23-Jun-06 3:19

We have an ASP with C# application that needs to perform some database work and if that is successful communicate with the clients COM ports and if that is successful commit the transaction and if not rollback.

Right now the applcation is registering a VB script for COM port work but gets no feedback on the success and blindly commits that transaction assuming it worked (not good). This is all pretty new to me, I have been doing C++ only.

Any advice would be appreciated.

Thanks,

Hi,
i many of the projects which went on the production server (uses sql server 2000)of other countries there was a common exception in all of them.It is the date conversion exception.Many suggest the way to do it is to
use culture attribute to store date in the sql server .Not shoor about it.Please suggest a way to store the date in the sql server such that
no problem would arise in future projects.

displaying a div dynamically whereever dropdownlist Box is present above it. [modified]

23-Jun-06 2:16

Hi,
i have a dropdownlist in which on changing the selection i have to give a tooltip above it to display the item selected because the size of the dropwnlist is small to accomodate the entire text .I tried in a dummy page like this.

div id="tooltip" style="LEFT: 488px; WIDTH: 229px; POSITION: absolute; TOP: 130px; HEIGHT: 19px" noWrap>
asp:dropdownlist id="ddl" oonkeyup='showTooltip()' style="Z-INDEX: 101; LEFT: 518px; " runat="server" Width="66px" !-->

But in real scenario in all the pages in which i have dropdownlist i have to incorporate this feature,but i cant change the layout of these pages to accomodate a div .So is there a way to show this tooltip dynamically using javascript (i.e even the div has to be created dynamically just above the ddl)on onkeyup event of the dropdownlist.

pls help me on this ,
thnks in advance

You could insert the div into the DOM dynamically from JavaScript, or possibly have a floating div on the page. I like the implementation www.netflix.com[^] uses when you hover over a movie.

Please lookup Document Object Model (DOM) on MSDN, or elsewhere, for a more thorough discussion.

You can access just about any object on the page in the browser window by using JavaScript.

<html><br />
  <body onLoad='InsertText()'><br />
    <div id='MyDiv'></div><br />
  </body><br />
</html><br />
<br />
function InsertText()<br />
{<br />
   oDiv = document.getElementById('MyDiv');<br />
   oDiv.InnerText = 'Hello, World';<br />
}<br />

Not proper code, but hopefully you get the idea.

The div tag is not present anywhere in the webform and has to be created on mouseover of the dropdownlist

Again, you can find much more info on this and other DOM related functions and properties by researching. The previous post was meant as an example to show the concept not an actual solution.

How to access a control created dynamically in a dynamically created table

widget123-Jun-06 1:58

widget1

23-Jun-06 1:58

I have a dynamically created table with formatted column headers and row headers and placed a hidden hyperlink (EDIT) within each cell on creation.

Dim bodyCell As TableCell
bodyCell = New TableCell
Dim e_link As LinkButton = New LinkButton
e_link.ForeColor() = System.Drawing.Color.White
e_link.Text = "EDIT"
bodyCell.Controls.Add(e_link)
headerrow.Cells.Add(bodyCell)

I am mimicking an excel sheet and want the user to be able to click in each cell block and if they do select that I want to chagne the color of the background to black to make it selected and vice versa if it is already selected I want to deselect it. I used a hidden hyperlink as it allows the click event - as I find a cross reference between the columns and rows as selected info from the database I color the cell background to black - I just need the syntax to also color my hidden hyperlink but not sure how to write it.:

For k As Integer = 0 To dtoutcomes.Rows.Count - 1
If CInt(dttabledata.Rows(t)("Outcome_id")) = CInt(dtoutcomes.Rows(k)("Outcome_id")) Then
MyTable.Rows(i + 1).Cells(k + 1).BackColor = System.Drawing.Color.Black
MyTable.Rows(i + 1).Cells(k + 1).HorizontalAlign = HorizontalAlign.Center

MyTable.Rows(i + 1).Cells(k + 1).?????
e_link.ForeColor = System.Drawing.Color.Black***** this is my error - but I need to color the hyperlink e_link to the same as the background as the cell background so that it remains hidden
End If

Thanks, Tammy
