Web Forms :: How To Display Image Depending Upon Db Field Value
Dec 29, 2010
this is my aspx page code :
<a runat="server" id="hlkmail"><img src="../images/send_mail_icon.jpg" alt="" /></a>
<a runat="server" id="hlkgallery"><img src="../images/galleryl_icon.jpg" alt="" /></a>
this is code behind (aspx.vb) :
hlkmail.HRef = "sndmail.aspx?Clientname=" & clientName
hlkgallery.HRef = "pgallery.aspx?Clientname=" & clientName
above code shows fixed images.
i want to display image dynamiccally depending upon the db value.
i have a stored proc that returns hasmail ='true/false' and hasgallery='true/false' from database.
if true i want to display send_mail_icon.jpg else send_mail_icon_watermark.jpg
and gallery_icon else gallery_icon_watermark.jpg. i want to do this in code behind using if loop.

I have a gridview which displays rows and columns all linked to an sql statement... and all works as normal.
I want to include a new column, that displays an image depending on what the value of the column is. If the column has a value - it will display an image. If the column value is null no image whill be displayed.
My sql is something like:
SELECT c.call_id, title, a.call_id as b_attach
FROM calls c
LEFT JOIN attachments a ON c.call_id = a.call_id
GROUP BY c.call_id,title,description, a.call_id
What's returns from this sql is:
Call_id | title | b_attach
1235 | title goes here | 1235
1382 | another title |NULL
So if there's something in b_attach - diplay image in gridview column, else display nothing in gridview column
My Gridview:

I have a gridview and would like to display one of 5 icons depending on the value returned from the database for that row (simply just A, B, C, D or E). Which event in my datagrid should I be looking at to check what value I'm getting? I presume once I can check a value I can simply set an image source using if statements?

I have a database, one field is named "clicked" with values 0 or 1.
When the gridview is displayed I would like to show the value from the field "clicked" to be displayed as an image (example: instead of 0 to display and for 1 to display)
Is it possible?

I am trying to bypass the ConfirmButtonExtender depending on the value of another field in the page. Basically, when a user click on my "Cancel" button, I normally display a modalpopup using the confirmbuttonextender and the modalpopupextender to display a dialog box confirming that they wish to cancel any changes they have made and return to the prior screen. If they click Yes, the button's onclick event fires which calls some code in the codebehind and redirects the user to another page. If they click no, it just returns to the same page, with no changes. However, in some situations, I know that my user is unable to perform any edits (they aren't allowed to) and for those users, I don't want to display the "Are you sure you want to leave you will loose any changes" dialog box. I've set a hidden checkbox field named "cbAllowEdit" to indicate whether the user is allowed to edit the fields or not. I was trying to use the technique found at link text to get this working but it just doesn't even seem to be firing the button's onclientclick event at all.
ASPX & Javascript
<asp:CheckBox ID="cbAllowEdit" runat="server" Checked="true" />
<asp:Button ID="btnCancel" runat="server" CausesValidation="false"
OnClick="btnCancel_Click" Text="Cancel" OnClientClick="disableSubmit();return false;" />
<ajaxToolKit:ConfirmButtonExtender ID="ConfirmButtonExtenderbtnCancel"
runat="server" DisplayModalPopupID="ModalPopupExtenderbtnCancel"
TargetControlID="btnCancel" BehaviorID="ConfirmButtonExtenderbtnCancel" />
<ajaxToolKit:ModalPopupExtender ID="ModalPopupExtenderbtnCancel" runat="server"
BackgroundCssClass="modalBackground" CancelControlID="btnCancelCancel"
OkControlID="btnConfirmCancel" PopupControlID="ConfirmCancelPanel"
TargetControlID="btnCancel" />
<asp:Panel ID="ConfirmCancelPanel" runat="server" CssClass="modalWindow"
Height="200" Width="450">
<p class="confirmMessage">
Are you sure you want to navigate away from this record?
</p>
<div align="center">
<p class="feedbackError">If you have made any changes to the record since the last time
you saved, they will be lost.</p>
<asp:Button ID="btnConfirmCancel" runat="server" Text="Yes" Width="75" />
<asp:Button ID="btnCancelCancel" runat="server" Text="No" Width="75" />
</div>
</asp:Panel>
<script type="text/javascript">
function disableSubmit() {
if (document.getElementById('<%= cbAllowEdit.ClientID %>').checked) {
return checkSubmit();
}
else {
return true;
}
}
function checkSubmit() {
var confirmButton = $find('ConfirmButtonExtenderbtnCancel');
confirmButton._displayConfirmDialog();
}
</script>
Code behind:
/// <summary>
/// Runs when the btnCancel button is clicked.
/// </summary>
protected void btnCancel_Click(object sender, EventArgs e)
{
Page.Response.Redirect("~/Searches/LookupCode/Default.aspx");
}

Inside my DB Table I have 2 Columns:
Column 1: ItemSent (Bit) TRUE or False and
Column 2: ItemPaid (Bit) TRUE or False.
Now in each row in my ListView I have to display 2 Images depending on Column1 and Column2
This part should be something like this:
If ItemSent = 1 Then
Img1.ImageUrl = "SentOn_png"
Else
Img1.ImageUrl = "SentOff_png"
End If
and same for the 2nd image
If ItemPaid = 1 Then .

I am in the process of moving all of the images in my web application over to a CDN but I want to easily be able to switch the CDN on or off without having to hard code the path to the images. My first thought was to add an HttpHandler for image extensions that depending whether a variable in the web.config (something like ) will serve the image from the server or from the CDN. But after giving this a little though I think I've essentially ruled this out as it will cause ASP.NET to handle the request for every single image, thus adding overhead, and it might actually completely mitigate the benefits of using a CDN.
An alternative approach is, since all of my pages inherit from a base page class, I could create a function in the base class that determines what path to serve the files from based off the web.config variable. I would then do something like this in the markup:
<img src='<%= GetImagePath()/image.png' />
I think this is probably what I'll have to end up doing, but it seems a little clunky to me. I also envision problems with the old .NET error of not being able to modify the control collection because of the "<%=" though the "<%#" solution will probably work.

I have a fileupload control in a contentplaceholder in a masterpage. I have to preview the image whenever I browse an image beside it in an imagecontrol.
My application is running on a different server .So I can't give the filepath of my local system.
Also I don't want to store the image in any location and i'm not supposed to use any session variable to pass it to generic handler.

I know how to display an image in gridview from image path in database. Now, I want to display an image in an asp.net image control from image path in database. Can anyone point me to a tutorial? I haven't been able to find one that explains how to do it when I don't know what the image path will be. The images are in the root folder.
