View 1 RepliesC# - Delete Entries In Static Dictionary When Not Used?
Jul 3, 2010I have a static class that holds a dictionary of objects. I have multiple threads that access this dictionary and create objects on it that are specific to that thread. How and when can I remove entries from the dictionary when a thread is "done"?
Basically this is a static class for an ASP.NET application that all requests can have "isolated objects" (that are related to the current thread) created in the dictionary. But, I don't really want to be tied to ASP.NET.

Forms Data Controls :: Delete Confirmation Box In Gridview With Edit And Delete Buttons?
Nov 18, 2010How do I reference the delete button to add the delete confirmation box when I have both the Edit and Delete buttons as the last two columns in the Gridview control. The following code works fine without any issues when I have the delete button only:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType != DataControlRowType.DataRow) return;
int lastCellIndex = e.Row.Cells.Count - 1;
Button db = (Button)e.Row.Cells[lastCellIndex].Controls[0];
db.OnClientClick = "if (!window.confirm('Are you sure you want to delete this record?')) return false;";
}
But, when I have both the Edit and the Delete buttons, I get the following error when I click the edit button while the delete button works fine.
Specified argument was out of the range of valid values. Parameter name: index
How do I reference the delete button so the edit button is not affected in this case?

Feb 8, 2010I have a grid contol that allows delete what I would like to have is someway to say Are you sure you want to delete?I found this code online, and tried it but it did not work, Do I need something more some behind code maybe?Here is what I found online:Adding 'Delete Protection' to controls If you use a control set up to allow Delete, the Delete button gives a straight delete without any warning, which can be dangerous.To give a warning dialog box, add an OnClientClick event to the Delete button, as follows.

runat="server" CausesValidation="False"
CommandName="Delete"
OnClientClick="return confirm('Are you sure you want to delete this record?');"
Text="Delete">

Forms Data Controls :: Dynamic Dictionary + Literals
Feb 1, 2011 I'm new to c# and .net but I think what I'm trying to do is fairly simple, however I think I'm getting stuck on variable types.So I have say 6 literal webcontrol myReq1, myReq2, myReq3.... and rather than implicitly setting them line by line I just want to run through a loop and set them dynamically. So to do this I've set up a dictionary that will contain the name of each literal, I can then run through those to add the data. This all works when I set up the dictionary by hand ie
Dictionary<int, Literal> myReqDict = new Dictionary<int, Literal>();
myReqDict.Add(0, myReq1);
myReqDict.Add(1, myReq2);[code]...
Obviously the Text inserted would be dynamic too, but you get the idea, so all that works just fine, but I'd like to do the Add part of the dictionary dynamically as well and that's where I'm running into trouble, I want to do something like:
Dictionary<int, Literal> myReqDict = new Dictionary<int, Literal>();
for(int cnt = 0; cnt<7 ;cnt+= 1){
myReqDict.Add(cnt, "myReq"+(cnt+1));
}
However this isn't valid, I can see why the "myReq"+(cnt+1) would not be valid as it's a String rather than a literal, but how can I convert the String to the Literal? What I am confused about is why the cnt on Add also isn't accepted, it is typed as an Int so to my mind it should be accepted

View 3 RepliesForms Data Controls :: ImageButton Inside A Repeater That Is In Another Repeater & Events?
Jan 18, 2010I have a user control that displays a shopping cart in an ecommerce application.
The main cart display is a repeater that renders as a html table. In one of those table columns, there is another repeater to display people associated with the products int he cart (it's a repeater in case there is a line item >1 with multiple people).
I've added an ImageButton that I want to use to change the person associated with the item. At first, when I'd click on it I was getting this error:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
So as an experiment I disabled EventValidation on the page (not the control it's self) and now I do not get an error, but I also do not ever hit the breakpoint I set in the innermost repeater's ItemCommand event.
So I wonder how I might do this without disabling EventValidation, because this control will show up on multiple pages and we don't want to edit them all. Also, I'll need to know not only the repeater containing the control's row that the event came from but also the row index of the repeater containg this one. Is this possible?

View 2 RepliesDataSource Controls :: Getting Returnvalue From Objectdatasource Delete Method?
Jul 13, 2010How and where can I get the returnvalue from my "DeleteGuestById" method to show the right error message to my user?
I have this:

If e.CommandName = "DeleteGuest" Then
Dim index As Integer = Convert.ToInt32(e.CommandArgument)

Dim GuestId As Integer = data.Values("id")
odsGuestlist.DeleteParameters.Clear()
odsGuestlist.DeleteParameters.Add("id", GuestId)
odsGuestlist.Delete()
End If
End Sub
In my BLL:

Dim returnval As Integer
GuestlistAdapter.DeleteGuestById(ID, returnval)
Return returnval

I think I have to be in the ObjectDatasources' "OnDeleted" method but I have no what code to place there.
