Wow.

Try reading the post on how to ask questions

1 - what is the error message ?
2 - what does the dll do ?
3 - are you expecting to call it on the server, or the client ?
4 - why are you using a COM dll at all ?

The regex one seems like the best bet to me.

I have a grid view. In that gridview I have somecheck boxes in EditItemTemplate. I need to validate those check boxes. I am using customValidate controls and java script to validate check boxes. but it gives me error message that IsActiveCheckBox is not found in current context. Mat be checkbox is in EditItemTemplate field. I am not sure. How can I fix this.
e'g

function ValidateIsActiveCs(source, args)
{
args.IsValid = document.getElementById('<%=IsActiveCheckBox.ClientID %>').checked;
}

<asp:CheckBox ID="IsActiveCheckBox" runat="server" Checked='<%# Bind("MyColumn") %>' />
<asp:CustomValidator ID="cvlIsActive" runat="server" ClientValidationFunction="ValidateIsActiveCs" ErrorMessage="This field should be checked">*</asp:CustomValidator></td>

<div class="ForumSig">seema</div>

IS IsActiveCheckBox your checkbox's ID?

If yes take it as ElementID

Try this code

args.IsValid = document.getElementById('IsActiveCheckBox').checked;

Hi,

Write a server side Function

public string GetCheckBoxId()
   {
       CheckBox chk = (CheckBox)GridView1.Rows[rownum].Cells[cellno].FindControl("IsActiveCheckBox");
       return chk.ClientID;
   }

then use this function inside java script

<br />
args.IsValid = document.getElementById('<%=GetCheckBoxId()%>>').checked;<br />

To succeed, we must first believe that we can.

There isn't any built scrolling properites but you may declare your datagrid within a div tag. Set the hight and width and there is a div scroll property.

Try something like this:

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 Smile | :)

Programmatically Getting the values of currenly displaying Details View Fields

kumswa19-Sep-07 4:01

19-Sep-07 4:01

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!
