View 1 RepliesHow to implement captcha in ASP.NET. I've a strange scenario where the captcha letter is showing correctly but the background image(the black dots) is not displaying.I checked it by using firebug in firefox,to my surprise i found that an additional div(which i have not written) is enclosing the captcha,and its background color is set to white.This is how i placed the captcha inside the form tag in aspx page
<div id="divCaptcha">
<cc1:CaptchaControl ID="Captcha1" runat="server" CaptchaBackgroundNoise="none" CaptchaLength="5"
CaptchaWidth="200" CaptchaLineNoise="none" CaptchaMinTimeout="5"
CaptchaMaxTimeout="240" FontColor="#529E00" CaptchaHeight="60"/> </div>
This is what i got when i checked using the firebug
<div id="divCaptcha">
<div style="background-color:White;">
<img width="200" height="60" border="0" src="CaptchaImage.axd?guid=1e625862-4447-41ff-a6a5-86ad1e95261a">
</div></div>
Code is too good. but its working only on local host.
When I upload my files on server,it didn't show captcha image...
I m using your Captcha Code [URL]. This code is working at local system but not working on Server Side. Captcha Image is not Displaying any Code.

I have a gridview with four columns, all sortable.
I need to refresh grdiview onbutton click.So if user sorted data by column1 then on button click gridview will be refreshed without sorting (as data comes from database).
I have a Page (created using master page) it has a UserControl and i want to reload the UserControl on button click (button in page outside the UserControl). I do not want to reload entire page. I want to reload just the UserControl.ASPX:
<asp:UpdatePanel runat="server" id="UpdatePanel" updatemode="Conditional">
<Triggers>
<asp:AsyncPostBackTrigger controlid="Button1" eventname="Click" />
</Triggers>
<ContentTemplate>
<uc2:GetUserScraps ID="GetUserScraps1" runat="server" />
</ContentTemplate>
</asp:UpdatePanel>
I am not sure what to do on code behind.
Is there any way to get click event of refresh button of browser ?

View 3 Repliesi have a web form in which i ve a button which will open a sliding pop up box(jquery) on click of it. In the same page i ve also a linkbutton for downloading files. Now the problem is first time wen i click that button it does nothing. (will not open popup box). Once i click on download button and then if i click that button it will open popup box along with download dialog box. Why is it happening so... is it because am using same event click for both these.
but download option is implemented in gridview_rowcommand()..
On my Search page, I have a search textbox, four drop-down lists and a "Search" button. If I use only the drop-down lists and click the "Search" button, results are immediately returned. However, if I enter text into the textbox and click the "Search" button, nothing happens until I click the "Search" button a SECOND time.The processes that occur for the latter scenario are as follows:Text entered into textbox, and Search button clicked:On FIRST click attempt:
1. Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load for Search.aspx is called
2. Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load for Main.Master.vb is called
3. Process stops! No results
On SECOND click attempt:
1. Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load for Search.aspx is called
2. Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load for Main.Master.vb is called
3. Protected Sub SearchSubmit(ByVal sender As Object, ByVal e As EventArgs) Handles btSearch.Click for Search.aspx is called
4. Search continues and completes.
So, why will the 3rd step not kick in until clicking Search for a second time
