How To Dynamically Assign The ImageUrl Property Of An Image Using Data Binding
Nov 11, 2010
I've got a SQL Server database with a table in it, which lists the file names of images. It's my intention to assign the ImageUrl of an Image control on the page, from the data in the table. I've placed a SQLDataSource control on the page, and then tried putting a FormView control there, and an Image control within that. But I don't see how I can assign the value to the ImageUrl property via data binding.

I am trying to load an image in my webpage from a file server where all of our images will be held.I set the imageurl property on the image control to dynamically;;
image1.ImageUrl =photo+"//"+image1.jpg;(Here photo is a string that value is: "//server/DBV/Documents/Employee/phot")
and I can see the image perfectly fine in IE.
However, the image does not show in Firefox. In Firefox it is just a blank screen when i am using developer tools that image button is in there but it showing faded in developer tool(firebug).in screen nothing showing only blank.

I've basically got 2 applications. One is my back office application (Admin) and the other , the front end application (web site)
My problem is that, the admin uploads 'n' number of photos ,which is stored in one of the folders within my back office application and the path is stored in my DB as , for example : ~/Uploads/test.jpg.
But it is not possible for me to access this image from my front end application because the path actually exists in my back office app. How do i get to view the images that I uploaded on my front end Appn. ?

I would like to dynamically load a user control and assign one of its public properties OnLoad...
I'm doing the following from a parent user control to dynamically load the child user control...
UserControl uc = (UserControl)Page.LoadControl("~/Controls/MyUserControl.ascx");
What else do I need to do to pass a value so its public property is set OnLoad?

I am attaching an image to a listview from code behind, the image depends on a value from the database and there are 5 different images.It sometimes works fine and then will randomly come up with an error, when nothing has changed, the error is:[Code]....
It doesn't seem to make sense to me because ImageUrl IS a member of image. Here is my code:

I'm trying to set the ImageUrl property after I've uploaded an image so that I can display the newly uploaded image, but for some reason it's not working.
If I navigate from the record I've just updated and then return back to that same record, the image then displays. It just doesn't display right after I've updated it. Basically what I'm doing is this:
Sub FormView1_OnItemUpdated(Sender As Object, e As FormViewUpdatedEventArgs)
Dim MyImage As Image
MyImage = FormView1.FindControl("Image1")
MyImage.ImageUrl = "image1.jpg"[code]....
I've left out the path intentionally because I'm pretty certain that the path I'm giving is correct... again, if I navigate away from the record and then return to it, the image displays. In addition, when I view the "Page Source" to view the resulting html, the src property of the image tag is blank . So, it's not a path issue... the issue is that its not setting the src at all which is why the image is not displaying.

I have a masterpage that contains all the javascript and inside the content control, there is a link that calls a javascript function and I want to pass the id once it's rendered differently by the server.
<asp:TextBox ID="txtstart" runat="server" Width="20%"></asp:TextBox>
<a title="Pick Date from Calendar" onclick="calendarPicker('<% txtstart.ClientId %>');" href="javascript:void(0);">
However, I keep getting this error:
Property access must assign to the property or use its value.
How would I be able to accomplish this?

So what I'm trying to accomplish is this
[Code]....
The user control has public properties named accordingly and the page has protected properties accordingly which I've verified have the desired values.
For some reason the values are always empty strings or 0s in the usercontrol, no matter what the page property is.

I have a ASP.Net page that has a gridview control. This gridView control has a checkbox controls. I would like to assign a boolean value from a database field to the Checked property- Checked='<%# Bind("RESULTS") %>'.
When page loads,I get error - Specified cast is invalid!
The code is as follows...
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="dsResults"
BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px"
CellPadding="3" OnRowUpdated="GridView1_RowUpdated">
<Columns>
<asp:TemplateField HeaderText="COMPLIANT" SortExpression="RESULTS">
<EditItemTemplate>
<asp:CheckBox ID="CheckBox2" runat="server" Checked='<%# Bind("RESULTS") %>' />
</EditItemTemplate>
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" Checked='<%# Bind("RESULTS") %>'
Enabled="False" />
</ItemTemplate>
</asp:TemplateField>
Note: If a constant value is passed at design time it works fine. But i want to assign the value at runtime using Bind.
Environment details: VS 2008, ASP.NET 2.0 and .Net Framework 3.0 & C# language.
I tried returning values like 0s and 1s, Ys and Ns and True and False from a database field. But i still get the above mentioned error.
I tried retreving the value in OnRowDataBound event using Eval, since Bind is not available in code behind. But it would make the field readonly and i cannot edit and update the Results field.
Even though there is a value returned by the query why does the Checkbox does not assign the value using <%# Bind("Results") %> to Checked property instead throws error - Specified cast is invalid.
how i can edit and update Checkbox.
where did the Bind method of ASP.Net 1.x is moved? How can i use Bind in code behind of ASP.Net 2.0?When i type DataBinder the intellisense shows Eval and other stuff but i don't see Bind that would solve the problem of two- way binding.

I have an update panel with an image control inside. At some point in JS I try to assign the image source, by doing
$("#pvwImage").attr("src", imageSrc);
The image refreshes correctly and shows me the assigned image. However when I click on a button that raises a postback, by the time it gets to the server the ImageUrl property of the image is still the default one, so my changes in JS didn't have any effect.

I have a website that sales associates access to view account information with clients. S.A's can only view information for accounts that they are tied to. Some clients have more than one account, S.A's can be tied to more than one account, but not all accounts of one client need to be tied to one S.A.
On the account info pages, I have account numbers (dynamically displayed labels) displayed of other accounts that the account client is associated with, which the S.A's can see. I'm modding this so that if the S.A has viewing permissions of any of the other accounts on that list of accounts, that instead of a label being displayed, a button directing them to that account page will display instead. In order for this to work, I have to attach a security function to the button, otherwise the page will blow out on the S.A's.
So I'm running a piece that is displaying a button instead of a label, which is working fine. My problem is when I try to attach the security event to the dynamically displayed buttons. It seems that the page just posts back and doesn't execute my code at all.
On my Page_Load, I'm running this after the buttons and labels are displayed:
For x = 0 to tblAccountList.Rows.Count - 1
'use a try to target the button, use catch to handle if it's instead a label, only one cell per row.
Try
Dim accountLink as Button = tblAccountList.Rows(x).Controls(0)
Addhandler accountLink.Click, AddressOf Me.PermissionViewCheck
Catch ex as InvalidCastException
Continue For
End Try
Next
I don't have any code checking for postbacks or anything like that, but the "PermissionViewCheck" event never fires and just reposts the page.

My code works fine when running it on my pc, but when I uploading it to the server, I always get the same error, I can't delete file I have just assigned into imageurl. However I able to delete it before using Image1.ImageUrl = sOldFileName; Somehow the server doesn't release sOldFileName after assignment it into imageurl. Here is the code, it's a pop up that gets the a variable from another page as a QueryString. The image blocks on the page load, before clicking the btnCrop_Click button.

I save the Image*URL* to the database and im trying to change part of my listview so I can display that image, every attempt ive tryed either results in server tag not well formed if I use an asp image or only the url path being displayed if i use a html img control. How can I combat one of these so I can display images via a imageurl in my listview?

I have an image inside a repeater, and I would like to change its IMAGEURL based on parameter that's being passed to it.
<asp:Repeater ID="Repeater" runat="server">
<HeaderTemplate>
<asp:Image ID="imgType" runat="server" />[code]....
There is a SWITCH statement in the code behind that is altering the IMAGEURL depending on what's being passed to it. Inevitably, however, the images ID ("imgType") is not visible to the SWITCH statement (presumably because it's inside a REPEATER).
