If you step through, I'd guess that one of these strings does not point to a record in the reader.

The only problem that i think will causing u this problem is that u write the code for creating images in the Page_Load event, u must write it in Page_init event
|

|
|
how can we use stylesheet?
|
|
|
|
|
|
first add the .css file in your project..
then go to the html view of your page and drag drop the file with in the head element
now u can set cssclass of your controls
google or anyother search engine is a good option for this kind of queries

It will because on pageindexchanged event you are binding the grid again. So all the checkboxes will be cleared. One thing you can try is storing the checked results on some temporary location like session when page index is changed. and when it comes to the previous pages, get values from this and check the checkboxes.

Hi
In Page Index, you are binding again to the datagrid. Checked values are not stored when you move out from that page.
Before clicking for sorting / paging, you should maintain all checked values (any unique id) in a hidden variable as comma-separated values. (That is,Use ClientID of that check box).
When coming back to a page, you should check whether a row (that row should be unique id) was already checked by comparing with that hidden varible. This can be done by using javascript in a for loop.
Hope you got it.

Hi all,
Iam using a client application developed in c# that connects to a webservice in a remote server.I have set the Client protocol version to 1.0 in the client application. The code is
protected override System.Net.WebRequest GetWebRequest(Uri uri)
{
System.Net.HttpWebRequest webRequest = (System.Net.HttpWebRequest) base.GetWebRequest(uri);
webRequest.ProtocolVersion = System.Net.HttpVersion.Version10;
return webRequest;
}
I compiled the application connecting to the webservice in the remote server.
But when i viewed the HTTP post info using Ethereal the POST info displayed was
HTTP POST/xx/xx.asmx HTTP1.1
RequestMethod:POST
RequestVersion:HTTP/1.1
Iam using the protocol version set to 1.0 in the code but the application is still using HTTP 1.1.Why?
Can anyone help me resolve this issue.
Any help will be appreciated.
Thanks

Hi all,
I m using the panel in asp.net 2003 .
I've used the panel many times before with buttons, but this time i need to use an update panel so that when a drop down list has its index chasnged that certain panels are shown and certain panels are hidden.
The problem i'm encountering is that the page does the post back,
on my page.aspx.cs i have the
on drp selected index changed event
if( drp.seleteditem.value==1)<br />
<br />
{<br />
panle1.visible=true;<br />
panel2.visible=false;<br />
}<br />
else<br />
{<br />
panel1.visible=false;<br />
panel2.visible=true;<br />
}
I AM USING .NET 2003. Can i implemnt this without postbacking???
Thanks in advance
All I ever wanted is what others have....

Panel will be rendered as HTML tables. So you can use javascript to do this without post back. Use panel id and get that id from javascript. Set style.display to show/hide it.
|
|
|
|
|
Yes, you can just use divs and set their style.display property to none or block, in javascript.

Hi,
Try this...
disable the autopostback property of dropdownlist
add following in page load
drp.Attributes.Add("OnChange", "javascript:selchange('" + drp.ClientID + "');");
Then your java script
function selchange(combo)
{
if(document.getElementById(combo).value=="MyVal")
{
//
//Here perform the hide , show operations
// Use div for that
//document.getElementById("MyDiv").style.display="none")
//or display="block"
}
}
To succeed, we must first believe that we can.

drp.Attributes.Add("OnChange", "javascript:selchange(this);"); is enough.
Sherin Iranimose wrote: function selchange(combo)
{
if(document.getElementById(combo).value=="MyVal")
No need of getting element again. use combo.value instead

Hi
try this
img.Click += new System.EventHandler(this.MyClick);
MyClick is user defined function.
protected void MyClick(object sender, EventArgs e)
{
//Your code will go here....
}

Hi,
Create a method with 2 arugments.
protected void img_Click ( object sender, ImageClickEventArgs e )
{
ImageButton img = ( ImageButton )sender;
Response.Write(img.ID + "
");
}
The above method will work as a handler for the click event of your dynamically generated imagebuttons.
To assign this event handler to the event of imagebuttons modify your for loop as following.
for (int i = 1; i < 11; i++)
{
img = new ImageButton();
img.ID = "img" +i.ToString();
img.ImageUrl="pg/1212/"+ i +".jpg";
img.Click += new ImageClickEventHandler( img_Click );
pl.Controls.Add(img); (pl is place holder control id)
}
I hope this will help you.
Thanks and Regards,

Hi,
you can pass ClientID of text box to the function.
And use the client id inside the getElementById.
