I have an interesting situation. I am doing a DB query to lookup email addresses from a SQL server table. I want to then put those addresses into an email to be sent programmatically. So there could be anywhere from 1 to x email addresses. Kind of new to asp.net and was curious as to the communities thoughts on if an array or collection would be better, or something else?

I would say use System.Collections.Specialized.StringCollection
This is a specialized collection of strings..
Or you can use System.Collections.Generic.List<string>
i.e.
System.Collections.Generic.List<string> myList = new System.Collections.Generic.List<string>();
If you know the exact number of results, array is just raw memory and fastest too, whereas using these above data structures requires some overhead..

Hi,
we are using asp.net 2.0 calendar control on our website. I have painted the calendar days with event information and set the tooltips for those days using javascript. But when the user hovers the mouse on the calendar, first it is displaying the control tooltip "Calendar" and if we wait for some time the tooltip will go away and the assigned tooltip will appear. How can I disable the control tooltip?
Thanks,
sridhar.

Hi,
You want to execute any server code on click of the row in datagrid?
If you want to use javascript then you can write follwing code in ItemDataBound event of Datagrid.
if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItem.AlternatingItem)
{
e.Item.Attributes.Add("onclick", "urjavascriptfunction");
}
I hope this will help you.
Thanks and Regards,
Chetan Ranpariya

if (dgvEmployee.CurrentRow.Index == -1) // Is there any row selected now?
return;
// Retrieve the first column from the selected row.
int Id = Convert.ToInt32(dgvEmployee.CurrentRow.Cells[0].Value.ToString());
This gives the particular value in the row of cell 0 ...If it help carry on
came out of hardwork

I have an XML file in my app_data directory. My Data Access layer (a class library project) needs to know where the XML file is.
I currently have:
c:\projects\My website\ (solution file is here)
c:\projects\My website\website (aspx files, web config, & junk)
c:\projects\My website\website\app_data\ (a few database files and an xml file)
c:\projects\My website\websiteDA\ (project folder for data access class library)
If I add the DA class library project as a reference to my website project, is there any way for the class library to know what the data directory of the website may be.
Using something like:
XmlTextReader settingsReader = new XmlTextReader("settings.xml");
tells me it's looking in:
C:\projects\My website\
the same folder as the solution file. Very odd. I would have expected c:\projects\My website\website
DB access gets around this by somehow parsing "|DataDirectory|" in the connection string, resolving it to match the app_data path. Could I do something similar?

That works if I'm trying to resolve a path from a page in the web project. However, I'm trying to accomplish the same from inside a class library referenced by the web project.

The class library code is running in appdomain of the web application so you have access to the HttpContext.Current.Server.

I managed to solve my own problem, and here it is:
string strDataDirectory = AppDomain.CurrentDomain.GetData("DataDirectory").ToString();

Have a menu control working fine, but need a couple tweaks. Example (assumes background white, hover background gray, also using css)
<asp:MenuItem Text="Cat" NavigateUrl="#" />
<asp:MenuItem Text="Persian" NavigateUrl="#" />
<asp:MenuItem Text="Calico" NavigateUrl="#" />
</asp:MenuItem>
<asp:MenuItem Text="Dog" NavigateUrl="#" />
<asp:MenuItem Text="Golden" NavigateUrl="#" />
<asp:MenuItem Text="Collie" NavigateUrl="#" />
</asp:MenuItem> Anybody know how or a tutorial that will show me how to do two things:
1. When hovering over "Collie", have the background of Dog be the hover color.
2. When hovering on "Collie" item but not on "Collie", have the entire item background be gray. Right now, if the text is short, and you hover to the right of the text within the item, the background remains white behind the text. I would like for the background to turn gray on the parent item, and the entire single item now matter where the mouse appears.
Thanks so much,
Janet

You'll need to use another control or write some custom javascript to handle these actions.
The menu control is rendered as a html table with the items as anchor tags in the cells. You would need to write some javascript to handle the onmouseover event of each anchor tag and adjust the colors as appropriate.

When you say "use another control" - can you suggest one that would do as I would like? Or, would they all have the same rendering problem?
And/or, do you know of a control or someone who has written the onmouseover for the menu control as you have described? Perhaps one you could recommend for a fee?
The main thing I'm looking for is the parent to retain the 'hover' color when on it's child.

Another third party control may provide better a experience for you. Without knowing your complete requirements or architecture I can't really recommend one.
If you want ot contact me offline we can discuss it further.

That's nice. It's usually more helpful to include the error when asking for help.
In this case however it isn't necessary. You are trying to use a server method (Response.Redirect) from the client side in your Javascript. It won't work.

I am building a shopping cart type web application. There are two web forms. The first web forms allows a user to select products. The second allows a user to enter quantities for each product selected in the first web form. I use a disconnected datatable to maintain and update selected products and quantities.
The problem is that the datagrid drops any quantity values entered by the user(there is only 1 input TextBox for each row in the datagrid). The code-
foreach(DataRow dr in dtShoppingCart.Rows)
{
if(((TextBox)dataGridItem.FindControl("txtSKU")).Text.ToString() ==
dr["SKU"].ToString())
{
dr["Quantity"] = ((TextBox)dataGridItem.FindControl ("txtQuantity")).Text.ToString();
break;
}
}
Any ideas?

Databinding is happening on the grid as it is being reposted to handle, which restores the textboxes to the original state.
Look at the Checkboxes and Textboxes section

For the most part that makes sense. Currently I am using a datatable. Do I update the rows in the datatable in the OnQtyChanged method and then rebind that to my datagrid? Does the OnQtyChanged method a replacement for the onclick event I am using now?
