Retriving images from Db - ASP.NET Discussion Boards

You can't.The browser will never post the full file's path. it is for security purpose Smile | :)

but you can try with e javascript before submit.

<asp:button onClientClick="document.getElementById('yourhiddenField1').value = document.getElementById('fileUpload1').value">

now you can retrive path from hidden field

Full path??

We can get like that, right? but of course, he can do nothing with this path..

document.getElementById('File1').value

Is it not what he meant?

You may be able to get it, I know for sure you cannot set it in script.

When the file is uploaded, the control has the full path. But, what do you hope to do with it ?

You cannot access the file system and you cannot interact with the file upload control on the client side.

Where is your Image Path?

set ID and runat server to htmlImage control in source and access that image and set src property to image path

if you want to display that image in datagrid try following code in itemtemplate

<img src='foldername/<%# Eval("ImagePathField")%>' />

You need to have the separated page that retrieve the image from database and write the binary....

In db iam stored like 9.jpg so iam retrieving like 9.jpg

But the image was in the folder(9.jpg) in the server.

This 9.jpg file name has to link with that folder to retrive the image.

while (dr10.Read())<br />

I don't think putting ~ will make much difference. This will force ASP.NET to take this path as the root only for server controls. But in this case he is writing image directly. So it won't matter I guess.

This won't display the image on a datagrid. Response.Write() prints the output on top of the page. Use a label control and assign this to there. Or use a server side image control and set image URL.

As you are trying to display images on a DataGrid, you should look into ItemDatabound event. This will be fired when each rows are binded. Create a template column in your datagrid which contains either a Label or Image control. In ItemDataBound, find this control and assign the image file name to there. Make sure the image exist in the specified path.

Hi fellows, I am really stuck into this thing.  I declared an iframe in a usercontrol control and this usercontrol resides in a form.  So now,i am getting an error that says document is null or an object.<br />
<br />
This is how I am calling from form.aspx to javascript to get the text from the usercontrol<br />
Form.aspx<br />
protected void Button1_Click(object sender, EventArgs e)<br />
{<br />
   ScriptManager.RegisterStartupScript(this, GetType(), "get", "javascript:getText();", true);<br />
 <br />
}<br />
<br />
usercontrol.ascx<br />
<iframe id="iframe" enableviewstate="true" runat="server"></iframe>                    <br />
<script language="JavaScript" type="text/javascript" ><br />
<br />
function getText()<br />
{ <br />
 alert(window.frames["usercontrol1_iframe"].contentWindow.document.body.innerHTML);--->and am getting error on this line.<br />
 <br />
}<br />
 <br />
</script>

netJP12L wrote:
alert(window.frames["usercontrol1_iframe"].contentWindow.document.body.innerHTML)

"usercontrol1" is something generated by ASP.NET engine so it might change it to something else sometimes.. You should check whether window.frames["usercontrol1_iframe"] has some values or not.. If you are using Firebug, it's so easy for you to debug this kinda scenario.

Hi Everyone,

I need help on my asp:menu which is bind to hierarchichal data source. It has no error but it's not displaying anything. This is my first time to use asp.net and I have spent a lot of time on this task. I know there are glitches in my classes and interfaces but just don't know what code I should write on it. Please help me. See discussion below.

Thanks,
Neil

I have a class called menuClass and class collection called menuCollection. menuCollection is populated correctly through a stored procedure. I could bind this to a datalist for testing purposes and it would display its content. The menuclass has String members menuid, parentid and title. The fourth member is a list type IList. Am not sure of the last member if it's necessary but based on my research it will be used for the GetChildren function.

To bind my menu item, I used the logic as follows:
dsView = New SQLDataSourceControlView(mnuTempItems)
mnuItems.DataSource = dsView.Select()
mnuItems.DataBind()

where mnuTempItems is an instance of class menuCollection.

See my other classes and interfaces needed for HierarchicalDataSource:

Encryption password and "encrypt & decrypt QuesryString" are two different questions. As the first question is already answered, I will tell you about second question.. You can use URL-rewriting with encryption class for encrypting /decrypting the querystring...
