hi,
i am developing a c# based web application. I incorporated a radgrid on to my user form, and filled it programmatically.
However i get an indexoutofrangeexception whenever i click to move on to the next page.
Below is the code that i ham using to bound items.
//CODE STARTS
<code>protected void rgCases_ItemDataBound(object sender, Telerik.WebControls.GridItemEventArgs e)
{
int index = e.Item.ItemIndex + (rgCases.PageSize * rgCases.CurrentPageIndex);
if (e.Item is GridDataItem)
{
GridDataItem item = (GridDataItem)e.Item;
lnkBtn = new LinkButton();
lnkBtn.ID = "LinkButton1";
lnkBtn.Text = "<a href='./CasesDetail.aspx?idCase=" + ds.Tables[0].Rows[index][0].ToString() + "'>" + ds.Tables[0].Rows[index][4].ToString() + "</a>";
item["idcase"].Controls.Add(lnkBtn);
}
} </code>
//CODE ENDS
The exception arises in the line
<code>lnkBtn.Text = "<a href='./CasesDetail.aspx?idCase=" + ds.Tables[0].Rows[index][0].ToString() + "'>" + ds.Tables[0].Rows[index][4].ToString() + "</a>"; </code>
The exception detail is as follows
There is no row at position 5.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details:
System.IndexOutOfRangeException: There is no row at position 5.
Source Error:
<code>
Line 299: lnkBtn.ID = "LinkButton1";
Line 300:
Line 301: lnkBtn.Text = "<a href='./CasesDetail.aspx?idCase=" + ds.Tables[0].Rows[index][0].ToString() + "'>" + ds.Tables[0].Rows[index][4].ToString() + "</a>";
Line 302: item["idcase"].Controls.Add(lnkBtn);
Line 303: }
</code>

I need the first tab to display a default aspx form in my solution. I am using Master pages and content pages. The aspx form is a content page.
Does anyone have a solution or even wording to Google for an answer? I haven't been able to find anything on Google yet as I'm probably not wording it correctly?
Thank you.

I have a master page with 2 divs a LeftColumn and MainColumn. My menu control is in the LeftColumn, the static menu is the same size as the left column so my dynamic menu pops out over the main column. My problem is when the dynamic menu pops out it is behind the content in my MainColumn. How can I get this to come out in front? I know the answer is right in front of me but I seem to be missing it. Any help would be most appreciated.

Hi guys,
You may have seen Ajax Textboxwatermarket effect. I am using that but the problem with this is anytime I try to enter anything on the textfield or textbox the width of the textbox gets slightly bigger, it doesn't stay what i have explicitly defin while coding my textbox. I even set the width in the CSS but still no result.
You may also see live on www.asp.net website and check this control. I would appreciate if anyone can help.
Thanks

I have a dropdown list.
It has following items
admin@sam.ca.gov Admin Miller
bobby@sam.ca.gov Bobby Gill
chris@sam.ca.gov chris Ghai
jim@sam.ca.gov Jim Ghotra
Here each item represent email address and his first name and last name. I need to select an item from drop down list and grab only email ID when I click on a button.
The domain of email is always same. i.e @sam.ca.gov is always same for all users.
Thanks in advance
seema

you can use a new string to copy the dropdown list item value/text and then u can use string operations to get the email id use the empty space as the escape sequence to get the string(i.e. email id)

Hi you can set value property of the dropdownlist to the first name or last name whatever you want.
like
dropdownlist1.Text="admin@sam.ca.gov Admin Miller";
dropdownlist1.Value="Admin Miller";

Hi there,
I'm trying to create bar-graphs that track a students progress a series of tests. Nothing fancy, just bar graphs for 5 different subjects. Y-Axis to contain marks and X-axis date on which the tests were taken. The results will be stored on an SQL database.They may/may not post a link to the graphs on their blog so that when the page loads, the graph should show up.
Any idea which product can do this for me? I had a look at Dundas and .netcharting but both have far more features than i need. Not to mention they waaaay too expensive  I just want to display the graph subject wise or all subjects on the page a la Google analytics.
Any suggestions?

And it's working great but as i'm sending normal text it's but as i provide some formatted text it's not..................
The code i'm giving below for sending mail.........
//For Sending The Mail

mail1.Subject="Mail From Manoj Bisht";
mail1.Priority=MailPriority.High;
mail1.BodyFormat=MailFormat.Html;
string body=HtmlTextArea.Value;
mail1.Body=body.ToString();
try
{
SmtpMail.SmtpServer="127.0.0.1";
SmtpMail.Send(mail1);
lblMsg.Text="Mail Sent Successfully";

I think you need to turn the event validation on the form off.
I didn't get any requirements for the signature

Hi Guru's
Im using ObjectDataSource for filling up the GridView, I'm just moving in on using objectDataSource, I find it handy since it trims up my code. After placing the requirement I'm encountering this issue No parameterless constructor defined for this object.
Please let me know what when wrong?
Regards
Dom

The class doesn't have a zero parameter constructor. Some object that you are using requires a zero parameter constructor (even if it doesn't use it).
Deja View - the feeling that you've seen this post before.

Here's the deal. Any serializable object must have a parameterless constuctor. For the Object Oriented beginner that means.
Class MyDataOject
{
public MyDataOject()
{
//parameterless consturctor
}
}
This is so that the object can be serialized to XML. Also you can not not have read only properties for the same reason. If a property is read only you can't recreate the object from xml. The objectDataSource probably serializes your class behind the scenes.
I didn't get any requirements for the signature

Public Function fill(Optional ByVal orderID As Integer = 0) As DataTable<br />
Dim cmd As SqlCommand<br />
cmd = New SqlCommand<br />
Dim da As SqlDataAdapter<br />

<br />
Try<br />
dt = New DataTable<br />

cmd.Transaction = _SQLTransaction<br />
<br />
If Not orderID.Equals(0) Then<br />
<br />
cmd.Parameters.Add(New SqlParameter("@orderID", SqlDbType.Int))<br />
cmd.Parameters("@orderID").Direction = ParameterDirection.Input<br />
cmd.Parameters("@orderID").Value = orderID<br />
End If<br />

da.Fill(dt)<br />
<br />
If Not dt.Rows.Count > 0 Then<br />
Throw New Exception("no record")<br />
<br />
Else<br />
Return dt<br />
<br />
End If<br />
<br />
Catch ex As Exception<br />
Throw New Exception(ex.Message)<br />
<br />
Finally<br />
cmd.Dispose()<br />
da.Dispose()<br />
<br />
End Try<br />
<br />
End Function
SP for the function above:
0 - returns all data
SET ANSI_NULLS ON<br />
SET QUOTED_IDENTIFIER ON<br />
GO<br />
<br />
alter PROCEDURE nw_spSelectOrders <br />
(<br />
@orderID int = 0<br />
<br />
)<br />
as<br />
begin<br />
<br />
Select o.orderID, <br />
od.quantity, <br />
od.unitprice, <br />
od.unitprice <br />
from orders as o<br />
left outer join [order details] as od<br />
on o.orderid = od.orderid<br />
where case when @orderID = 0 then 'selected'<br />
else<br />
case when o.orderID = @orderID then 'selected'<br />
else 'not selected'<br />
end <br />
end= 'selected'<br />
end
Whats wrong with passing 0? when I explicitly place orderID number I get result but passing 0 nada..
Please advice
Thanks Guys

Uhh please advise what? The error is REALLY descriptive, and two people here have given you the answer.
I advise you learn .NET or something, if you can't even figure out what a paremeterless constructor is.
