May be you are not passing enough number of arguments when calling the javascript function!
If possible post the javascript function you have written along with how you are calling that function from your application.

You need to include the image folder into your web site and then include the image into you web site. If the image is out side your web site the web site doesn't have access to the image. Also if you don't include the image with the web site when you deploy the web site the image won't get deployed with it.

Change the tag's src attribute to point to the location of the image you want to display.
Another reason why it's not being displayed is that the path to the image may be wrong.
You don't have to be AFRAID!

By the above statement I understand that you want to use Gridview.
To use it you just have to drag and drop a Gridview on your Design pane.
And then bind it to a datasource. That is all you have to do to make it work.
Hope it helps....
You don't have to be AFRAID!

Hi,
I have an Asp.Net application that gets price feeds for different stocks via a dll-binary.
When running the application in visual studios built-in ASP.NET Development Server, it works fine, but when i publish the application the function that gets the feed doesn't work. To be sure i set impersonate to true and run as a local administrator but it still wont work.
What else is the difference between running an application in IIS and in visual studios built-in ASP.NET Development Server that could cause a problem as this.
Im thankfull for every tip i can get.
Regards
Hmitosh

but what problem? is access denied?
<< >>
|
|

|

The problem is that the method returns 0 instruments instead
of 1 as it is supposed to. It executes the method so there doesn't seem to be an access problem. The object containing the method is a legacy com object. Could it be that IIS has problems running COM-objects.
Regards
Hmitosh

|

Apparantly the COM object is listening on a port for incoming data.
could it be that IIS blocks the port. In that case is there a way to ublock the port.
Regards
Hmitosh

|

if so, you can check your COM able to listen successfully on that port? or it's already registered by another program? or it's blocked by some firewall or something like that...only you might know

I forfot to say. But it works fine when i run in Visual Studio Built in Web Server, it doesn't work when i run it on IIS on the same computer. That means that there is some difference in the way the theese two web services works.
My thought was that there is a problem having a com object running in IIS that listens on a another port but i havent been able to find out.

Hi All
I have a problem with maintaining view state in WebCustomControl.
The problem is that i want to create a generic search control.
All controls that is used in search criteria is passed from hosting page
e.g
TextBox txt1 = new TextBox();
TextBox txt2 = new TextBox();
TextBox txt3 = new TextBox();
Control[] c ={ txttest, txt1, txt2, txt3 };
SearchControl.WebCustomControl1.AddControls(c);
Where Add control is Satic method in webcustom control
its code is as
public static void AddControls(Control[] Controls)
{
UIControls = Controls;
}
where UIControls is static Control array defined in Custom control
I then Render the control as
protected override void RenderContents(HtmlTextWriter output)
{
output.Write("");
for (int i = 0; i < UIControls.Length; i++)
{
output.Write(" ");
output.Write(" ");
output.Write(" ");
}
output.Write(" ");
output.Write(" ");
output.Write(" ");
output.Write("");
UIControls[i].RenderControl(output);
output.Write(" | ");
output.Write("");
output.Write("");
output.Write(" |
");
}
Now the problem is that when i access any of the control, its value is lost!
Any one that can help me plz
regards

Is there a way to access the .Text value of a Textbox control on the Masterpage from one/all of its Contentpages. If not, what is the best way to share data between pages.
I am using VWD Express.
Thanks,

If you set the MasterType Page directive, then your page will know what kind of master page it is in. Then you should be able to access controls on the master page.
<%@ MasterType virtualpath="~/Masters/Master1.master" %>
Here is some sample code from microsoft help:
Visual Basic
<pre>
Sub Page_Load()
Dim mpContentPlaceHolder As ContentPlaceHolder
Dim mpTextBox As TextBox
mpContentPlaceHolder = _
CType(Master.FindControl("ContentPlaceHolder1"), _
ContentPlaceHolder)
If Not mpContentPlaceHolder Is Nothing Then
mpTextBox = CType(mpContentPlaceHolder. _
FindControl("TextBox1"), TextBox)
If Not mpTextBox Is Nothing Then
mpTextBox.Text = "TextBox found!"
End If
End If
' Gets a reference to a Label control not in a
' ContentPlaceHolder
Dim mpLabel As Label
mpLabel = CType(Master.FindControl("masterPageLabel"), Label)
If Not mpLabel Is Nothing Then
Label1.Text = "Master page label = " + mpLabel.Text
End If
End Sub
</pre>
C#
<pre>
void Page_Load()
{
// Gets a reference to a TextBox control inside
// a ContentPlaceHolder
ContentPlaceHolder mpContentPlaceHolder;
TextBox mpTextBox;
mpContentPlaceHolder =
(ContentPlaceHolder)Master.FindControl("ContentPlaceHolder1");
if(mpContentPlaceHolder != null)
{
mpTextBox =
(TextBox) mpContentPlaceHolder.FindControl("TextBox1");
if(mpTextBox != null)
{
mpTextBox.Text = "TextBox found!";
}
}
// Gets a reference to a Label control that not in
// a ContentPlaceHolder
Label mpLabel = (Label) Master.FindControl("masterPageLabel");
if(mpLabel != null)
{
Label1.Text = "Master page label = " + mpLabel.Text;
}
}
</pre>
Hope that helps.

Hi every one,
I need to call a method resides in another .aspx file from another .aspx file (all in the code behind)..
I tried making it public and static but still I can't access it, I can solve my problem if I could make the second page to post back when the first one do post back..
Any suggestions??
Thank You very much

You need to place your function (which you want to call in more than one pages) in a separate class, then make an instance of that class in your page and call that function. Simple Object Oriented Programming

mubashir is right
You need to Crerat a separate class
inside the class create a satic Method e.g
Public static void MyFunction()
{
//some code
}
the function can be then call in many pages
Note: The class must be of public scope
