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.

Hi after or before saving this file just open this file using streamreader or like that class(File handling). then make it single string then its easy by String.substring() method.

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

hi can some one give the simple answer what is impersonation
i am not getting correct information , would appreciate if someone gives a good answer
Thanks
sri

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?
