Try something like this:
<br />
((HyperLinkColumn)grdSR.Columns[X]).DataField = "NewDataField";<br />
Where X is the index of the column you want to edit

Hi,
basically impersonation is a means for a particular process account to access a given ressource on behalf of some other process accounts. Simply speaking, say i am a user process and i have access to some local resources on my computer. You are another process which does not have access to local resources on my pc. If you really need to access these local resources, i can give you access by letting you "impersonate" me (i.e temporarily take my identity).
This often occurs in ASP.NET where the account IUSR_YOUR_MACHINE_NAME is required to execute some resources to which it does not have rights. In this case, you have to give ASP.NET the right to impersonate another account (say admin account for example) to do the job.
Eg. If you need to save a file on the server and the account IUSR_YOUR_MACHINE_NAME does not have enough rights to do it, it is a common practice to allow ASP.NET to temporarily take the identity of another account to perform the job.
This is how it can be done in the web.config file:
< identity impersonate="true" userName="MyDomain\Admin" password="admin"/>
Hope this helps

Hi all,
I have a link button on my aspx page, and also a Details View control.
When the user clicks on the link button, we want to get the currently displaying values from the fields in the Detailsview and send out as email.
We already have a sendNotification function to handle the sending of emails.
Are there any properties of the detailsview that will give us the values of the currently displaying fields?
ie using vb.net:
Protected Sub lnkSendMail_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles lnkSendMail.Click
SendNotification( DetailsView1.[property or properties combinations].ToString(), [sender], [Recipient], [subject] )
End Sub
Thanks!

I need code in C# to populate checkbox in gridview to delete records.
Please help.
Thank you

Hi!
I am asuming that you have placed check box in your grid. You have a delete button in your page. When you click on that button, it will delete all records for which the check boxes were checked.
If you have a different scenario then plz let me know.
You can use the following code in the onclick event of that button.
protected void btnDelete_Click(object sender, ImageClickEventArgs e)
{
string strUserId = "";
foreach (GridViewRow gv in gvUsersToDelete.Rows) //traverse thru each row of the grid
{
//chkDelete is the name of the checkbox you placed in the grid. We first find that checkbox from the current gridview row and get it in a local checkbox type object, cb.
CheckBox cb = (CheckBox)gv.FindControl("chkDelete");
if (cb.Checked == true) // now check if the check box in this row is checked or not
{
// our grid had User ID in its column 0. So we are getting the userid from the 0th column in the //current row.
strUserId = gv.Cells[0].Text;
DeleteThisUser(strUserId); // passing userid to DeleteThisUser function.
}
}
}
private void DeleteThisUser(String strUserId)
{
// code to delete the matching strUserId.

You can't use a message box in an ASP.NET application. How do you catch the exception, and how do you want to show the error message?

Hi,
I'm using the .NET 2.0 Membership provider. I have a gridview that displays the user names. But I want to display more info for each user like last login date, if he/she is locked out, etc. I'm not exactly sure how to do this because System.Web.Security.Membership.GetAllUsers doesn't have these methods, but MembershipUser does. I do not know how to do this so it displays this extra info for each user.
Please can someone advise?
Regards

GetAllUsers returns a collection of MembershipUsers. So what is the issue?

hi
i have got Below Error When i down load file from any site and my Application is Continue Debug More time then I got following Error .
if any one has solution then please help me.
"may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during running operations."
thank
in Advance

Download the file in a separate thread. If you do it in the main thread, it won't be able to respond to any events while the download is going on, which will make your application look like it's stuck.

Hi All,
I have to show some data into DataGrid. Now there is one Button, On click of that Button this DataGrid should be converted into PDF format and mail this PDF file. Is it possible?? I have tried some 3rd party component to do so. But I cant get the result.
I have successfully added one DataTable into PDF format. But not a dynamic DataGrid..
Plz help me, if anyone have some idea about this......
Thank you
Keep Smiling...........

Before converting into PDF, Rebind Datagrid or any dynamically created cotnrol.

The quickest way i see is to programmatically navigate to the URL and programatically perform a printscreen and save the clipboard data to to file.
Dunno if this is of any help.
