my gridview is
[Code]....
On Row_DataBound I have
DirectCast(GridView1.HeaderRow.FindControl("Header"), CheckBox).Attributes.Add("onclick", "javascript:SelectAll();")
But I am getting an error of : Object reference not set to an instance of an object.
I also try
DirectCast(e.Row.FindControl("Header"), CheckBox).Attributes.Add("onclick", "javascript:SelectAll();")

i am trying to do is set my page up so that when a user clicks on a row in the gridview a hidden checkbox is unchecked... i am new to asp.net but never thought something as simple like this could be so difficult to work out... i've been on it for around 5 weeks now, i started this on my first day of the website, and have actually designed and written the entire site while still trying to work this out... i first did this on the selectedindexchanged event:
Dim cbox As CheckBox = CType(GridView1.Rows(GridView1.SelectedIndex).FindControl("CheckBox1"), CheckBox)
If cbox IsNot Nothing Then
If cbox.Checked = True Then[code]....
problem is the above code throws up errors...! once i take out the where clause it unchecks every checkbox and writes it back... is there a way i can say just uncheck the selectedrow checkbox and update that one row???
i'll admit there are better ways of doing this, and i'm sure the above code is a little messy,

I've been searching in all the forums, and websites for the last 4 hours without finding a solution for a problem that in the beginning I tought it was an easy one!!!This is my problem, I have a gridview with the following colums: select (link), Room Type (for hotels), and TotalThe total field Is a template field it has in the custom binding property a function: find_total(Eval("Room")) this function makes some calculation and returns the calculated Total value, and shows in the gridview without problems,The thing I cant do is: when the user clicks on the select link I want to get the text of the template field and put in a label control.
I tried, almost all the events of the datagrid, to reference the content of my template field but sometimes I receive a null value (seems that Im looking for the value before the find_total function has been executed) or I get an error "the index is out of range".I dont know how to approach this, I tought It has to be much easier, but Im very confused right now, if anybody knows how to do this

I have a form free user feilds, some drop down which are populated by a database data and a button. I want to create a new line in a table when the user clicks on the button. the values for this new line will come from the Values (not visible content) of the drop box, the content of the text feild, the user ID that I should get from the connection and the current date... ie, I want do do a INSERT INTO table (userid, dropdown, text, date) values (how do I get the user ID from the session?, how do I get the value from the drop down?, how do I get the text from the text box?, how do I get the current date?)

I have two checkboxes: cb1 and cb2. They are both hooked up to an onClick event which checks if at least one checkbox is clicked. If this is not the case, it throws an alert and reverts the change. If a legal change was made (e.g. cb2 was checked, followed by cb1 being unchecked), the function calls the server function checkChange() which needs the object and eventargs.
I'm having trouble with the following:
Reverting the change: how can i find out which checkbox was clicked without adding an extra javascript function for the second checkbox? This has to be a scalable solution as more checkboxes may be added later.
How do I call the server function checkChange(). I am aware of "this.Page.GetPostbackEventReference" but I am confused as to the parameters it takes.

I have a page which allows the user to send email. After they click the submit button, I display a confirmation message. However, if the user clicks the browser's Refresh button once the confirmation message is displayed, the email is sent a second time (or a third, fourth, fifth, etc.). What can I do to prevent the Refresh button from resending the email?
