You need to use
overflow:scroll to the container that holds the grid.

Have you considered using real variable names, or are you trying to make your code hard to read ? What does your aspx look like ? I would recommend before you ever consider charging anyone for your code, that you learn how to write professional code as it pertains to database access. I'd fire anyone who wrote SQL in the presentation layer. What insanity is it that you want to rebind this control once for every row in your grid ?

If you're a beginner, I assume no-one is paying for this code. It's sure not worth any money. So, instead of trying to solve this problem ( and this code is FULL of problems ), why not start slower and work through a book. You won't have to worry about sticking to a specific problem and solving it, until your code is at a professional standard, and someone is paying for it.
There is so much wrong with this code, I wouldn't know where to start.

Yes.. If your footer contains the control, find only in the footer...
where is if condition before running FindControl.

Try ! This...
DropDownList ddlResultsFooter = (DropDownList)e.Row.FindControl("ddlResultsFooter");
if(ddlResultsFooter != null)
{
//Bind you drop down here
}

I have a gridview control, which contains multiple rows. Each row has a link-button and a detailsview control. Using the link-button, i want to show or hide the detailsview control.
Initially all the details view have their css property Display=None set. If the link button in any of the grid-view row is clicked, i want a java-script to make the details -view in that row visible (Display=Block)
So i wrote the following javascript:
<script language="javascript" type="text/javascript">
function ShowReplyBox(PMBox) {
myElement = document.getElementById(PMBox);
if (!myElement)
alert('element not found');
myElement.style.display = "block";
}
function HideReplyBox(PMBox) {
myElement = document.getElementById(PMBox)
if (!myElement)
alert('element not found');
myElement.style.display = "none";
}
</script>
While showing the details-view control, it shows momentarily, and again become invisible automatically ...
What could be the problem ...

The script looks fine. I assume your code is calling the show and then the hide script right away.

Depends where you mean. I'm yet to see what code calls these methods, returning a true or false from these methods may stop the other events from triggering, but I can't say, because you've not posted the code that is relevant. your code has no bugs that I can see, it's just being called in ways you don't expect.

Replace your code with this ...
function ShowReplyBox(PMBox) {
var myElement = document.getElementById(PMBox);
if (!myElement){
alert('element not found');
return;
}
if(myElement.style.display != "block")
myElement.style.display = "block";
}
function HideReplyBox(PMBox) {
var myElement = document.getElementById(PMBox);
if (!myElement){
alert('element not found');
return;
}
if(myElement.style.display != "none")
myElement.style.display = "none";
}

Would setting the display to block if it already is, cause it to disappear ?

No. I dont think so.
if I set display = "" it will act similar to display="block"
I dont know what is wrong with his code... Might be his code calling the display="none" just after setting display="block"
|
|
|
|
|
Yeah, the problem has to be that his code is calling both methods. Funny how people ask for help, then don't answer with the details you need to help them

Hi guys,
I'm wondering if it there is a better way of doing this, I have 2 webpages, page1 and page2. I want to ensure that users would go to page1 before going to page2 (a button on page1, redirects it to page2), so that if the user types in the URL of page2, it will redirect to page1 first. I am currently using the Request.UrlReferrer.ToString() to get the the previous webpage and comparing it. If it is from page1 then page2 will open if not it will redirect to page1 (the code is below). I'm just wondering if there is a better way of doing this?
Thanks.
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
if (Request.UrlReferrer.ToString() != "page1")
{
Response.Redirect("page1");
}
}
}

I would put pages one and two on the same URL, as controls. Then I'd use viewstate to store if the user had viewed page one before allowing page 2 to show, and set something on the URL to show page 2.

Can that be easily done? I have a lot of controls in page1 and page2.
