But is it possible to implement it without any troubles?
Because of the pages throwing events and catching events maybe...
Also I didnt found much information on google about doing it manually

I am not well versed in ASP.NET so how to do this is really escaping me.
I want to display the value of one of the properties from an object conained in an arraylist using c#
This is kind of what I mean but, of course, this doesn't work
string mystr = myArrayList[0].strValue;
myArraylist[0] cantains an object with property strValue. I know I can't use the [] in the expression but how do I access that property?
The help is much appreciated.

This has nothing to do with ASP.NET.
Your problem is that you're using an arraylist, which is not strongly typed. In future, I suggest you define 'doesn't work', so people can help you better, but in this case, I know it 'doesn't work' because you're not casting the object. Use a List instead, never use the non generic collections.

You're scolding me for using outdated code right?
I inherited this code with an arraylist. Maybe I should switch it over, but I did resolve my problem with the arraylist once I figured out my way around a foreach
foreach ( object myobj in myArray)
{
mystringbuilder.Append( myobj.myproperty);
}
Anyway, thanks for the reply

how to integrate the following pseudo-class into ASP.net
<style>
a:link {color: blue;} /* an unvisited link */
a:visited {color: purple;} /* a visited link */
a:hover {color: red;} /* a link with the mouse hovering
over it */
a:active {color: green;} /* the selected link */
</style>
because I want to realize the mousehover ona linkbutton to change the color,
but I do not know how to use the css style, for self-defined css style, we can sue sth like
<div class="style_deine_1" >
thanks!

Use MouseOver and MouseOut for Change the color of hover. And For Rest, only using the CSS Class.

thanks, again, but I did not understand you.
here, I also want to know that is it possible to use these css styles in ASP.net, if so, how?
|
|
|
|

Ohh. I missunderstood yout question. You do it like this way,
.MyHperLink{
font-family: Verdana;
font-size: 11px;
color: #006DB1;
}
.MyHperLink:a
{
color: #006DB1;
text-decoration:none;
}
.MyHperLink:hover
{
color: #13B12D;
text-decoration:underline;
}
Do all other stuff for active etc.
Set CssClass="MyHperLink" for link button.

thanks a lot.
I tried, it seems that css does not work for linkbutton, no idea why.
but it does work for others such as BulletedList.
|
|
|
|

it is strange that I can not find function to set the color for a linkbutton when mouseover,
it should be a normal function, but...
e.g. anyone can give me one hint?
e.g.
asp:LinkButton ID="LinkButton6" Font-Underline="false" ForeColor="White" BackColor="Green" Font-Size="Medium"
Font-Bold="false" Font-Names="Arial" runat="server" BorderStyle="Double"
BorderColor="Silver"> Download Statistics</asp:LinkButton>
|

|

use OnmouseOver and call a javascript method to change the style

it does not work, because I use ASP.net linkbutton, the ID can not be found by javascript function by using GetElementByID,I do not know why.

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";}
}
Please clik on any "Ekle" button in the following web-page to see what I mean.

[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.
