i need to allow our users to select 6 items from a larger list. i want to implement ajax. but i'am new to it.
i dont want to use lists exactly. what i need is that the items will be displayed as images. i want the user to drag from the larger list to the list he prefers. also i might want the user to re arrange the list he has created.
I have no idea of how ajax works.
i would appreciate if anyone can give me suggestions

what do you expect from other forum members?
What is your exact problem. After 6 highways of code I don't see your problem

update , delete not working,i am using store procedure pls help me
|
|
|

What I see in your SqlParameter usage is that you expect that the rowdata is found in the footerrow. That may be for new data but for data loaded from a DB you need the objects used in the row.
For the correct usage of UPDATE and DELETE, search Google or use the ask the SQL forum of CodeProject

Hello friends,
I am adding some checkboxes dynamically by following method:
Dim chk As New CheckBox
chk.ID = "Random String"
chk.Text = "Random String"
chk.AutoPostBack = True
AddHandler chk.CheckedChanged, AddressOf chkSelected_CheckedChanged
Page.Form.Controls.Add(chk)
I have also added event handler of checkbox as:
Protected Sub chkSelected_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs)
Response.Write("
" & sender.Checked)
End Sub
I am also trying to access these controls by FindControl() method as ".netman" told to.
But the problem is i am not able to check or uncheck those checkboxes and also those are not showing in FindControl() method.
I even tried to create controls in Page_Init method but its still not working.
Can anybody tell me what is wrong?
Thanks and Regards,
Nagendra

Try this sample.This is working.
I take one PlaceHolder and one button control on page.
On Page_Load event,I create two checkboxes
protected void Page_Load(object sender, EventArgs e)
{
CreateCheckBox();
if (!IsPostBack)
{
}
}
Create Checkbox Method
public void CreateCheckBox()
{
CheckBox chk;
for (int i = 0; i < 2; i++)
{
chk = new CheckBox();
chk.ID = "chk_" + i.ToString();
chk.AutoPostBack = true;
PL.Controls.Add(chk);
}
}
Now I check status of checkbox on Button Click event.
protected void btn_Click(object sender, EventArgs e)
{
for (int i = 0; i < 2; i++)
{
Response.Write(((CheckBox)this.Page.FindControl("chk_" + i.ToString())).Checked);
}
}
Note: You need to create checkboxes on every event of the page so I call that method out of IsPostBack condition.

Hi
In my update panel I display a gridview but the paging doesnt work.
When I click on a number at the bottom it doesnt do anything
Why would this be?
thanks
|
|
|
|

Are you binding the DataSource again once you call the PageIndexChanged event? If no, do that. If you does, post you code..
|
|
|
|

Yeah that worked!!
thanks

Hello
Each Time i add a grid View in my page,

"BC30456: 'GridView1_RowCommand' is not a member of 'ASP.default_aspx'."
Any Help Will be greatly appreciated
Thanks in advance

It might be you have assigned 'GridView1_RowCommand' as OnRowCommand event in the HTML Source code but no definition in the codebehind.
|
|
|
|
|
Yes, I wrote my gridview directly in the html
So what i should do
Thanks in advance
Assaf

Thank you
The idea is get it

From the html code of ur asp.net application delete
OnRowCommand="GridView1_RowCommand" where grideview is defined

Did you tried anything.
Because its not that much difficult to convert a data table to excel.
Search 'google' you will get lots of samples.Try it out and if you are stuck somewhere, come back.
Somebody is rating down your questions, do you know why?
EVEN THE WORD IMPOSSIBLE SAYS I M POSSIBLE.
