Change this to
cobo_emp_id.DataSource = ds.Tables[0];

You have to save the Image to the Server (file path) and set the ImageUrl property of the Image control to the file path.

You can also use Binary datatype, which is common for all the binary files (doc, xls, whatever)

No, I have saved the image in the sql column as image datatype.
And i have retrieved the image and converted to bytes[] as in the previous message.
I am trying whether it works out from System.Drawing.Image to System.web.UI.Image.
My Actual problem is to load the image directly to the treeview icons.
Also I don't get "Image" property in the Intelisense box. It shows only the "Image Url" Property. How to define the image.

That is what I am telling you. There is not property as "Image" (which accepts bytes/System.Drawing.Image as value) in web world. So, you have to get the bytes and store it as a file (say mypicture.jpg), then use that image url and assign that to the ImageUrl property of your TreeView icons.

You would have to create a seperate page or preferable an http handler for you image. You would set the image url on your tree view to this page with, for example, a query string parameter identifying the image in the database to be retrieved.
e.g. ImageUrl = "MyImagePage.aspx?ImageId=XX";
Then inside your MyImagePage.aspx you would write some code along the lines of that shown below. Note: You must make sure no other content is sent down along with the bytes i.e. no html in the code infront if you use an aspx page (which is one reason why a handler would be better).
byte[] abImageData = (byte[])command.ExecuteScalar();<br />
<br />
Response.ContentType = "image/jpeg";<br />
Response.Write(abImageData);<br />
Response.End();

Hi,
I have a dropdown,textbox,"Go" button and a gridview.I have bind the dropdownlist with the column name that appear in gridview.I have written the following code for binding the dropdownlist with the column that appears in the gridview and call that method on the page load.
public void GetColumnName()
{
try
{
for (int i = 0; i < GridView1.Columns.Count; i++)
{
if (GridView1.Columns[i].Visible == true)
{
DropDownList2.Items.Insert(i, GridView1.Columns[i].HeaderText);
}
}
DropDownList2.Items.Insert(0, "-- Search By --");
}
catch (Exception ex)
{
lblMsg.Text = "The following Error has Occured:- " + ex.Message;
}
}
Now i want to filter the data in the gridview.If user select a particular column name from the dropdownlist and enter some text in to the textbox and click the "Go buton",the grid view should filter the data according to that column name which user has selected in the dropdown and the text that the user has enter in to the textbox and show it in the gridview.
Please let me know how to filter the data in gridview by column name.Currently i am in the middle of the project.Please explain by giving some example or by providing some useful link related to this topic so that i can refere to.
Thanks&Regards

This means, you are requesting a Page which does not exists in the website.

ie: http://10.0.0.3/MIS2/INDI_AGE/ShowINDI_AGETablePage.aspx
but when I try to access it using an external ip address (I got it from www.whatsmyip.org), it's not accessible.. you can try it here:
http://82.114.160.32/MIS2/INDI_AGE/ShowINDI_AGETablePage.aspx

Is your machine is a single user machine or connected with any LAN?
If you are connected with LAN/WAN, the IP address is the IP address of your ISP server. It would be common throughout your network. Ultimate you are accessing your your website through ISP server which does not exists.
|
|
|
|
|

What you actually want to do?
Are you trying to access your website outside your network or inside your network?
If you want to expose your site outside the network (Internet), you cannot not do it with your current network settings.

Sorry Muammar,
I am not a Network Guy. I know little bit about Network, which normally we should consider while programming.
My advice is to get assistance of a Network/System Administrator and try whatever you like to achieve.
Exposing your machine to internet is high not recommendable since your security settings are not that good like server machines to defend.
If you want to access your website in your Intranet, just you have to add an Exception to the Port 80 (default website port) in your Personal Firewall.
