I have some issues regarding listing images from inside a directory. What I want to do is to create a Default.aspx page that will search and list the images located inside a folder of my website (where I simply drop them in it). I tried with a treeview, DirectoryInfo and both worked when I compiled my website with visual studio, but when I access them via another computer, I get a 404 for the page. My bet is that iis7 is blocking my code from accessing the folder containing the images. Any idea of how to fix this and make it work ?the code I use to browse in my image folder
string path = AppDomain.CurrentDomain.BaseDirectory;
DirectoryInfo diFiles = new DirectoryInfo(AppDomain.CurrentDomain.BaseDirectory + @"contentmiscimages");
foreach (var f in diFiles.GetFiles("*.jpg"))
{
Lit.Text += "<a href="" + f + ""rel="lightbox[img]" title=" + f + ">" + f + "</a>" + "<br />"; //I format the image as an url inside a literal
}
I have a nested formview. I need to set a value for a textbox when I'm in insert mode from parent formview which is editmode.
View 4 RepliesI am trying to tweak a ASP intranet website that was created for my company. It uses a control to show all files in a folder, so they can be selected with ease by our employees. What I would like to do if possible is set it up where if a new form is added a bubble notification will appear next to the tabbed section. See the image below to see what I am refering to. I spoke to our site designer and he stated it is not possible. I feel that with all the creative minds in the world anything is possible. [URL]
View 2 RepliesI would like to ask if it is possible to access data on a master FormView from a nested detail FormView.
I have a main form (master) with several tabs (detail) and would like to display a label with text from main form that is hidden by the tab at the moment of editting. My asp page looks like this.
[Code]....
Is it possible to get the value of the label CompanyTextLabel from CompanyTextBox using just ASP.NET expressions or something similar without writing c# code in .cs file?
I made a web form on a development website of mine (we'll call it dev.somewhere.com) and tried to publish it out to the web (we'll call it [URL]) in a subfolder. I named it default.aspx like I was supposed to and it worked flawlessly on the dev site. When I published it out the web, I wound up getting the following error when trying to get to the subfolder: [URL] Directory Listing Denied
This Virtual Directory does not allow contents to be listed. Confused and flustered, I tried to go to [URL], but I wound up with some error that won't tell me the problem. Instead it tells me to change the my web.config to read <customErrors mode="Off"/>.
I have a main formview which contains another formview. In the second formview I have a section that needs to insert/update. I want to access this formviews events for example I can access the main formviews item inserted event in the code behind:
FVInvoiceHCPAgreement_ItemInserted
I can't choose the nested formview events in the code behind
ie. FVInvoicePaymentInfo_ItemInserted
I have tried adding the ItemInserted event in the .aspx page
i.e. onItemInserted = "FVInvoicePaymentInfo_ItemInserted"
but for the handles clause it can't see FVInvoicePaymentInfo.
I have installed blogengine and dasblog in my system.when i try to open those pages i get the folloeing error in ,my web browser
Directory Listing Denied
This Virtual Directory does not allow contents to be listed.
i have the following scenario: one formview. when in editmode there is a child formview linked to the other by a column value. i need to take the value of one of the values of parent formview controls and set it to a textbox of child formview in insert mode. I wish to know which event should I use in codebehind to bind both controls? (that escenario will have paging and must keep the binding as if it was master detail)
View 9 RepliesI've seen various tutorials and scripts online which show how to create a directory tree which list the file name, size etc.My question is, I need a script that is basically a normal directory listing but it doesn't show the file extension. If anyone can even point me in the right direction it'd be of much help!
View 28 RepliesOn page load is there a way to enumerate all the nest user controls for that specific page load?
I'd like to be able to enumerate all the user controls that implement an interface, and call the interface method for the controls before asp.net passes control to thier page_load events.
The problem is from the master page level, any page in the app could be loading, and each of them could have any random user control, and I need the type reference to determine if they implement the interface, and to call the method.
has anyone got any pointers for recursively listing the directories and file structure within an FTP space with the built in .NET FTP client, ideally I would like to bind the results to a tree view at once.
View 3 RepliesI've just started developing a web site in VS 2008. When I try and view the page (click 'start debugging') an IE window pops up displaying a directory listing of all the files in my web application directory rather than my masterpage or content. Why is this and how can I correct it?
View 2 RepliesI'm having a problem trying to retrieve a dropdownlist value that is located within a nested repeater. Basically I'm trying to create a shopping cart that allows the user to select a shipping method and the shipping method is contained in the repeater. So my page structure looks something like this.
Gridview
[Code]....
To me this should work, but the problem I'm facing is that there are no repeater items. The Items.Count property in the repeater is 0. I am not calling DataBind on the Gridview nor the Repeater before this code is reached (this code is the first thing that happens in my button click event) and my binding is done inside a !IsPostBack statement in my page load. I've made sure databinding is not occurring by setting breakpoints on the code that databinds both the gridview and repeater.
It seems to me like the nested repeater is losing it's viewstate or something on a postback. If that's the case, how can I get the selected value of that dropdown control inside a nested repeater?
Hi, i am newbie to asp.net. In my page there is a formview with sqldatasource. In which there is a dropdownlist wrapped with an updatepanel. What i'm trying to do is the re-bind ddlStudents after adding new row to the students table (using gridview and
ajax popup extender-both working fine, i'm being able to add new )
<asp:UpdatePanel ID="ddlUpdatePanel" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:DropDownList ID="ddlStudents" runat="server"
DataSourceID="sdsStudents"
DataValueField="studentID"
DataTextField="name"
SelectedValue='<%# Bind("studentID") %>' >
asp:DropDownList>
</ContentTemplate>
</asp:UpdatePanel>
<asp:SqlDataSource ID="sdsStudents" runat="server"
ConnectionString="<%$ ConnectionStrings:myConnectionString %>"
SelectCommand="SELECT studentID, name FROM tblStudents">
</asp:SqlDataSource>
after closing the popup,
Protected Sub btnClose_Click(ByVal sender As Object, ByVal e As EventArgs)
If IsPostBack Then
ddlUpdatePanel.Update()
ddlStudents.DataSourceID = "sdsStudents"
ddlStudent.DataBind()
modalPopupPanel.Hide()
End If
End Sub
I am getting error;
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
One of the fields on my formview is a dropdownlist. When I go into edit mode the dropdownlist gets set to the correct value and works fine up to this point. Problem is I just can't see how to get the newly selected value of the dropdownlist to persist to the database when update is clicked. The DDL is a category list and I want to allow changing of the category for each record. Like I said I have it working so it displays the correct category for the record but if I change the DDL (change category) the new selected value doesn't get updated in the database. It just keeps using the binded value that was originally assigned to the selected value of the DDL. see code snippit
[Code]....
The above snippet is how I am binding the DDL. Now to not bore you with a ton of code paste I use various events of the formview to make sure the value displayed in the DDL is correct for the record that I am viewing at the time. All that works just fine. Where I need some pointers is the when I enter edit mode and change the DDL from say fire to ice it isn't getting persited to the database, all other info in the record gets updated just fine but the DDL never changes. I have tried several angles to getting this working and TBH my brain is yelling BREAK TIME.
How can I hide the directory listing in web-browser?
View 1 RepliesI'm populating a dropdownlist in a formview with a different datasource from the formview's. I need to set the selected value according to the value in the formview's datasource but I'm having a hard time doing that.

DataSourceID="SqlDataSource1">

I have a ddl inside the formview that I can't figure out how to wire up properly. The formview contains detail info, but the ddl needs to list the entire set to items. Then I want the ddl's selected value be set from the recordset intended for the formview. I think it's just a timeing issue s I would like your help. Thanks, - EJM.

I have a dropDownlist in a Formview Edit and Insert Template that is Bound to a Field, It is for a credit card expiration date, so I want to programatically populate it so it will automatically show the next 8 years from this year. Works fine!
Except When I add it to the Formview, and click on edit it gives me an error basically saying my record does not match the list item data, but it should since it shows the year just fine. So I am figuring that it is not binding the ListItems to the dropdownlist.
I have tried every event I could try and I always get the same error. I have tried the ModeChanged, DataBound, DataBiding, PreRender, Load on both the Formview and the DropDownList, but no go. How do I do this?
[Code]....
This works fin on a DropDownList that is not in a FormView, so I know its not the Code. and the record I am updating is 2010, so the record is not out of range
On my formview I have a drop down list that is populated with the names of the files in a certain directory. This works fine, but when the drop down list selected value is bound to the database field I get the following error :
'ImageFileDropDownList' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value
I have setup other drop down lists in the same formview populated from SqlDataSources and these all work fine. I can see perhaps why this is an issue because I have not specified a DataValueField or a DataTextField for this drop down that is populated in code (whereas I can for the SQL bound ones) because I'm not sure what these settings would be.
I need to have a "blank" option as well so that the field does not default to the first value in the list.
