Forms Data Controls :: Populating A DropDownList In A ListView InsertItemTemplate

Jan 19, 2010

I have the following ListView (extra code removed for clarity) :

<asp:ListView ID="lvParticipants" runat="server" DataSource='<%# Eval("Participants") %>' >
<EditItemTemplate>
<asp:DropDownList ID="ddlCountry" runat="server" SelectedValue='<%# Eval("Country") %>'
DataSource="<%# GetCountries() %>" DataTextField="Text" DataValueField="Value" />
</EditItemTemplate>
<InsertItemTemplate>
<asp:DropDownList ID="ddlCountry" runat="server" SelectedValue='<%# Eval("Country") %>'
DataSource="<%# GetCountries() %>" DataTextField="Text" DataValueField="Value" />
</InsertItemTemplate>
</asp:ListView>

The Insert row in the ListView has an empty DropDownList and GetCountries() is not called. However, if I click the Edit button on an existing row, GetCountries() is called twice (not sure why) and the DropDownList is properly populated. Why isn't the InsertItemTemplate DropDownList getting populated?

Forms Data Controls :: Populating Dropdownlist Inside Listview Control Dynamically?

Mar 5, 2010

I have a dropdownlist in EditItemTemplate and InsertItemTemplate which I want it to populate at the runtime while Inserting an item or Editing an item.

I am facing an issue regarding populating a dropdownlist dynamically while in Edit and Insert mode. There are 0 Records in my table and it shows "Empty Data message" in my Listview control. Even the ItemDataBound event does not fire. So I am not able to find the dropdownlist in that listview.

This is my Aspx code which shows only InsertItemTemplate and EditItemTemplate.

Forms Data Controls :: Populating DropDownList Inside A ListView Inside A FormView

Jan 16, 2010

I have the following (abbreviated) code:

<asp:FormView ID="FormView1" runat="server" DataKeyNames="ItemID" DataSourceID="LinqDataSource1">
<EditItemTemplate>
<asp:DropDownList ID="ddlCategory" runat="server" SelectedValue='<%# Eval("Category") %>'
DataSource="<%# GetCategories() %>" DataTextField="Text" DataValueField="Value" />
</EditItemTemplate>
<ItemTemplate>
<asp:ListView ID="lvParticipants" runat="server" DataSource='<%# Eval("Participants") %>' >
<InsertItemTemplate>
<asp:DropDownList ID="ddlCountry" runat="server" SelectedValue='<%# Eval("Country") %>'
DataSource="<%# GetCountries() %>" DataTextField="Text" DataValueField="Value" />
</InsertItemTemplate>
</asp:ListView>
<ItemTemplate>
</asp:FormView>

When the FormView is in Edit mode, ddlCategory is populated as expected by calling GetCategories(), which returns a List of categories. However, when the ListView is in Insert mode, ddlCountry is empty. I put a break point in GetCountries(), but it never gets called. If I change the name of the method, I get an error. So it recognizes the method at compile time, but does not call it at run time. I'm guessing this is an embedded binding issue of some kind, but I'm hoping someone can save me a lot of time by pointing out the solution.

Web Forms :: Post Data To External Page And Set Session Variables

Aug 17, 2010

I have an app which has a form that used to use AutoPostBack rigged controls (dropdowns, radiobuttons etc.) in an updatepanel, and I used to set session values on each postback. I posted the form using PostBackUrl to an external page, using a bit of javascript OnClientClick to copy my data into meaningfully named hidden fields.

Now, I've had to rewrite the AutoPostBack-ing controls so that all the cascading dropdown work and date calculation etc. is done in JavaScript, and not in C# - no more postbacks, no more updatepanel.

This means I've lost the ability to set my session values on postback. Can anyone think of a solution for setting these before I post my form? I need to set the session variables, plus post (querystrings are not an option) to the external page with the values from my form - and actually send the user to the external page, too.

Web Forms :: Populating Dropdownlist From Session Variable?

Nov 3, 2010

To speed things up for the visitor of my web page, I put a personalised dropdownlist in a session variable (as below).

The idea is that if the user is logged in and the ddl session variable is Nothing then it should be set here, and the next times the dropdownlist should be set from this session variable.

The session seems to be populated ok, but the resulting dropdownlist (ddlMenu) doesn't (it just becomes blank). I suspect that it has soemething to do with the way I try to assign it. No matter what I try I run into problems, saying that one thing is a one-dimensional array and the other thing a listitemcollection, or the like. What should I write in the last line?

If Session("aid") IsNot Nothing And Session("ddl") Is Nothing Then
Dim ddlny As New DropDownList
ddlny.Items.Add(New ListItem(vstr, ""))
ddlny.Items.Add(New ListItem(kontrstr, "PageA.aspx"))
ddlny.Items.Add(New ListItem(bstr, "PageB.aspx"))
If dt IsNot Nothing Then 'dt is a datatable, populated elsewhere
For i As Integer = 0 To dt.Rows.Count - 1
ddlny.Items.Add(New ListItem(dt.Rows(i).Item("name"), dt.Rows(i).Item("did")))
Next
End If
Session("ddl") = ddlny
End If
ddlMenu.Items.Clear()
ddlMenu = Session("ddl") 'THIS IS THE LINE THAT SHOULD BE REWRITTEN.

Pdf - Maximum Amount Of Data Stored In Session Variables?

Jan 11, 2011

I have a form where users can upload Pdf files(about 30 pages to one document or so). I want to delay storing these Pdfs in the database until the user submits the entire form. The problem is that the collection of files uploaded must be able to persist through postbacks. That being said, I am considering storing these as session variables, however, would this be too much data to store, or are session variables meant to store a couple strings here and there? If this method is not acceptable, is there an alternate method?

ADO.NET :: Creating An Entity Data Model Filtered On A Session Variables (C#)

Nov 1, 2010

I'm trying to customize correct displaying of dropdownlists so information shown in comboboxes is relevant to the kind of user logged on (maintaining referential integrity at data level)

e.g.: I have a user already logged on and depending on his profile I'd like to display to this user only the portion of the database that he would be allowed to see. That would mean that he might have acces to an specific subset of data, e.g.: businesstype = "3", loging level = "2", etc.

Is there a way of creating an Ado.Net Entity Data Model filtered on a Session variables as to maintain proper referential integrity at data level?

IIS InProc Session Variables Randomly Not Written To Session

Nov 12, 2010

There are reams of info out there about things causing InProc session to drop session objects, but that's not what's happening here. We're missing individual variables within stable InProc session objects, and are not sure whether they're not being written or being lost after a successful write. I've confirmed with WinDBG that the sessions are live and contain some, but not all, of the data written to them.

Guid g = System.Guid.NewGuid();
this.Context.Session.Add(g.ToString(), result.ImageData);
output.Write("<img src="display.aspx?id=" + g.ToString() + "">");

This code is pretty straightforward, and it works flawlessly in Test. In Production, under heavy load, though, it fails ~1% of the time. If Mr Smith visits the site and attempts to display 4 pieces of image data, 2 of them might be saved in his session and two of them be lost. The InProc session object for Mr. Smith exists. The traffic logs show he clicked 4 times, each with a different id param. But there are only 2 guids in his InProc session object, instead of 4. The 2 session objects we did capture do correspond to 2 of the id's shown in the traffic log (his 1st and 3rd clicks.) The traffic logs for his 2nd and 4th clicks, though, show a guid id that's not in his InProc session object.

Lines 1&3 of the above code obviously worked for those 2nd and 4th clicks, or he'd not have had the id in the URI for him to click. Line 2, however seems to have failed silently in some way. If any exception had been thrown, I'd expect we'd not ever have arrived at line 3. I can't see any way for the user to receive the guid id, but the session to fail to have it. The other possibility is line 2 worked successfully, but the variable later disappeared, how I cannot even imagine.

Details:
ASP.NET v3.5
IIS 6
No Web Gardening

We're running a web farm, but users constantly return to the same server. I'm researching now whether there's any way users might be slipping off to the other server.

DataSource Controls :: Assign Dataset Values Retrieved From Database To Session Variables

I am using an object datasource to retrieve the data from the database but I cannot find anywhere that shows how to assign these values to variables. The data is returned in a dataset. There is the added problem that there will be mulitple items returned which will have to be assigned to different arraylists of objects based on the a primary key in the database.
