Because, your LinkButton is Server Side Control. So, for that you need to first get ClientID then need use getElementByID.
var LinkClientID="<%=mylinkbutton.ClientID%>";
var NewID=document.getElementByID(LinkClientID);
Now use NewID for all operation,
Please check syntax once
Hope this will helpful to you.

Which Framework do you have in your system ? Is it 2.0 or 3.5 ? Based on that you need to use that dll.

Hello,
For some reason I need to know which image-button causes postback. The following code does this job very well (according to coordinates). However when I click on a image button in a datalist. Somehow datalist items disappear. When I disable the codes(at pre_init) that calls the following function, the image button of the datalist works very well. Does anybody have any idea? Only you gurus would help me. Thanks in advance.
private string getPostBackControlName()
{
Control control = null;
string ctrlname = Page.Request.Params["__EVENTTARGET"];
if (ctrlname != null && ctrlname != String.Empty)
{
control = Page.FindControl(ctrlname);
}
else
{
string ctrlStr = String.Empty;
Control c = null;
foreach (string ctl in Page.Request.Form)
{
if (ctl.EndsWith(".x") || ctl.EndsWith(".y"))
{
ctrlStr = ctl.Substring(0, ctl.Length - 2);
c = Page.FindControl(ctrlStr);
}
else
{
c = Page.FindControl(ctl);
}
if (c is System.Web.UI.WebControls.Button ||
c is System.Web.UI.WebControls.ImageButton)
{
control = c;
}
}
}
if (control != null)
{
return control.ID;
}
else { return "budegil";}
}

[System.Web.Services.WebMethod]
public static DataSet GetContactName()
{ DataSet ds = new DataSet();
XmlDocument doc = new XmlDocument();
ds.ReadXml(System.Web.HttpContext.Current.Server.MapPath("App_Data/Group.xml"));
LoadData(ds); ?????
}
I need to bind this ds to a repeater control.
public void LoadData(DataSet ds)
{
DataSet ds = GetContactName();
repeaterGroup.DataSource = ds;
repeaterGroup.DataBind();
}
My question is, how to call LoadData from above webmethod. LoadData() method is not recognized from the webmethod.

How can a web-service method binds data? If LoadData() method is in your web page and you are trying to call it from web-service, then whatever you are doing is pointless. Do more reading on web-services and how they work before you work on them.

Everything has a necessity and I wanted to clearly communicate that am not a beginner.
Please ask why this is needed if you are interested to help or opt to stay out. There will be somebody else who will be willing to help. When I have posted a question on a forum, it clearly means I am looking for a solution.
This is what am trying to achieve.
Ajax control, collapsible panel extender(cpe) needs to expand a panel containing a repeater control and load data into repeater when the panel is expanded.
I found that there is no server side click event but there is an expand-collapse javascript handler.
To call server side code from AJAX, Pagemethods can be used.
<asp:ScriptManager ID="ScriptManager1" EnablePageMethods="true" runat="server">
</asp:ScriptManager>
[System.Web.Services.WebMethod]
public static DataSet GetContactName()
{
DataSet ds = new DataSet();
XmlDocument doc = new XmlDocument();
ds.ReadXml(System.Web.HttpContext.Current.Server.MapPath("App_Data/Group.xml"));
LoadData(ds);
}
public void LoadData(DataSet ds)
{
DataSet ds = GetContactName();
repeaterGroup.DataSource = ds;
repeaterGroup.DataBind();
}
I am not able to access LoadData from GetContactName(). Any help on this would be greatly appreciated.

you're not a beginner, but you want to know how to call a non static method from a static method ?
The only way to do this, is to have an instance of the class that contains the non static method. However, as your control is within a page lifecycle, you can't just create a page instance from out of nowhere, it won't create the lifecycle you need, as a page is not being requested. Therefore, it cannot be done, you need instead to create a page lifecycle, and call your method within that lifecycle. Otherwise, there's no chance you're going to see anything appear in your page.

Hello,
In my ASP.Net application i am using AJAX. Basically i am implementing Chat Application.
At a time many chat windows will be opened and based on the AJAX time interval messages will be updated in the chat screen.

I want to know number lines while printing on the paper.
To know the number of lines in a file is hardly helpful in my case.
I have marked and underline my question to better understanding.

I think I understand your question.
Let's say you read 100 lines from your database and you want to display them on a page with a maximum of 60 lines per page.
Try something like this:
Lines = 100
Page = 0
PageSize = 60
While Lines > PageSize
Page = Page + 1
... Load your HTML PageData ...
Lines = Lines - (PageSize)
End
Page = Page + 1

No, actually I have all html data in an hidden fields.
Your solution is a good for static data but I need to print rendered data

Hello,
I have a big problem that I could not overcome. I have a datalist placed in Ajax-update panel. I inserted a command button that is supposed to insert the item to another datalist.
when I clicked on the button, somehow the datalist items disappers. Therfore the itemcommand event is not fired at all. What I know is that, the viewstate hold the infrmation and the items should be there despite the postback.
Is there such a problem commonly faced or , is theresomething wrong with my settings?
All the best.
