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.

I just switched from Jsp to Asp.Net.
My working .aspx file has become very large , and i am using a wizard and i want to separate codes for each step in different files .
Cann anyone Help , coz it become so bulky !

If you are using ASP.NET 2.0 there is a wizard control that should help you. Consider your design also. Is it necessary to have everything all on the same page, or would breaking it up into more pages be better for development, maintenance and performance?

One solution is to use web UserControls
User controls come as ascx files and contain the same functionality (even pageload is there) as an aspx. The great thing is that you can dynamically load and unload usercontrols on an aspx by using a panel or some other methods.
In visual studio, add a new file of type " Web User Control" for each step of your wizard and add the required coding in each ascx.
Then use a panel in your aspx to load and unload the different user controls programmatically.
Hope this helps.

Not a good architecture for building a wizard. Loading and unloading user controls on the fly has problems that will become apparent when you try using doing it. Have you?

I did use it but not for wizards. Can you please tell me more about these "practical problems" plz?

If you had seriously used this technique for real production applications you would have encountered the issues of state management and viewstate corruption.
