What is the best way to create a hyperlink to a ListView's items? I'm trying to enable users to simply click on any of the ListView's items, which in turn has to effect that a detailed page for the specific item is opened in a new tab. Right, I got it working by using a Hyperlink component, which is a step closer to my goal.How to make the entire ListViewItem clickable.
View 3 RepliesI'm trying to update items in my SQL database from a ListView. It works, but all entries in the database update. Not just the one I'm working on. I backed up the database prior to testing, so there's not any issues there.This is how my SqlDataSource UPDATE command is setup:
SQL Code:
UPDATE entries SET duration = @duration, checkinDate = @checkinDate, receivedBy = @receivedBy, cosmeticDmgIn = @cosmeticDmgIn, STATUS = N'closed'
I don't have any code setup to update the database, which is probably the issue.When I load the ListView, select edit, type in my edits, and click "Update", all the rows in my database, for that column, are updated with that data.I tried inserting the parameters manually, within the ItemUpdating event, but it never works.
i want to create a dynamic listbox where items are links (each item is a hyperlink)
here 's my code:
Using sw As StreamWriter = New StreamWriter(Server.MapPath("~/Output/" & weeknumber & ".xls"))
Dim hlk As New HyperLink
hlk.NavigateUrl = ("~/Output/" & weeknumber & ".xls")...
[Code]......
It always displays ONLY 10 items although there are 30 items in the datatable. If i use GridView ALL the 30 items are displayed just fine.
So I have a ListView (assignmentsListView) in an UpdatePanel, being filtered by a DropDownList in the same UpdatePanel. The DropDownList has a list of persons in it and uses autopostback, and the ListView shows the tasks those persons are assigned to.
I am trying to use code similar to this:
[code]....
When I first load the page, the DropDownList shows the first person in the list, and the ListView correctly shows that persons tasks.
If I then select a person who I know has zero tasks, I get an error at the RegisterPostBackControl() method, saying the passed-in control cannot be null.
When debugging, at the RegisterPostBackControl method, it shows that the ListView Items collection has >0 elements in it (the number of elements matches the person selected before the current person).
Does anyone have an example for how to create a Dynamically Templated Listview with prefernces page to specify which columns & column order)? Also the listview would also have Edit, delete and insert options if possible. And uses the n-tier approach with Bus Layer and does NOT use LINQ.

I am using a listview control to display items.i am having a hyperlink and a label field in the item template of the listview control.
<ItemTemplate>
<asp:HyperLink ID="HyperLink3" Text='<%# Eval("title") %>' NavigateUrl="~/template.aspx" runat="server">HyperLink</asp:HyperLink>
</ItemTemplate>
How can i access the click event of the hyperlink field.Suppose if i want post values from the click event of the hyperlink how can it be done?
I have a gridview with this code:
DataNavigateUrlFields="uId,bUserId,bNavn"
DataNavigateUrlFormatString="Pdfiso.aspx?uId={0}&Over=1&bUserId={1}&uName={2}"
/>
To the hyperlink field I wish to add data from external date, and I have tried this, but it doesn't work,
Code:
Protected Sub Gridview1_PreRender(ByVal sender As Object, ByVal e As EventArgs)
Dim test As String = Request.QueryString("lang")
For Each row As GridViewRow In GridView1.Rows
If row.RowType = DataControlRowType.DataRow Then
Dim grdviewLink As HyperLink = DirectCast(row.Cells(0).Controls(0), HyperLink)
grdviewLink.NavigateUrl += "&lang=" & Convert.ToString(test)
End If
Next
End Sub
I will add the code lang to the URL including the querystring
I'm binding data from a SQL table to a GridView. The data looks like this:
During the initial bind, all I'm pulling is the raw data and adding it. As each row is bound, I convert the latter two columns into the hyperlinks like so:
VB.NET Code:
'Get the second link text Dim lnktextBOM As String = e.Row.Cells(2).Text 'Create link Dim lnkBOM As New HyperLink lnkBOM.NavigateUrl = getSqlData.getBomURL("notebooks", e.Row.Cells(0).Text, e.Row.Cells(1).Text) lnkBOM.Text = lnktextBOM 'Add the link to the cell e.Row.Cells(2).Controls.Add(lnkBOM)
Which all works great. However, if I'm using Chrome and I click on the URL, nothing happens. On FireFox, a 404 is thrown. But on IE, it works perfectly.
what I'm doing wrong here? Below is an example of the URL:
CTSFS01SharedOPERATIONDWURBOMAdamo__PROJECT A.xls

I have a ListView control in Asp.Net WebForms which display a set of elements, I have at the end a "More" button like Facebook for example. During the postback I want to get from database another 10 elements (I have already displayed 10 and I don't want to retrieve them again)
Something like this.
foreach (var item in New10Items)
ListView.Items.Add(index,DataItem)
the problem is with DataItem, how to Bind it before add it? what is the best way of solving this?
I am currently using Visual Web Developer and have a website with 2 pages which are "Tables.aspx" and Variables.aspx". I was wondering if their is a way to make a specific cell in a gridview clickable/as a hyperlink so that it would take the user to another page and display the required information in another gridview based on what Table Name from the gridview has been clicked on?
The gridview on the "Tables.aspx" page has 5 fields and they are Table ID, Table Name, Table Description, Source and Record Count. The field that I want to make as a hyperlink is the Table Name field and when clicked upon I would like all the relevant information (Table Name, Variable Name, Variable Description) for this field to appear in a gridview in the "Variables.aspx" page. The database table names that would be required are "variables" and "tables". In order to do this would I have to create/run some sort of SELECT command in behind the source tab for the gridview?
NB table name comes from tables database table and variable name and variable description comes from the variables database table.

I am trying to use checkboxes to select the items in a Listview. I have added a checkbox control in the , and they are displayed properly.
The problem is that Checked property never changes when I click on them. Why does this happen?
Here is the code:
<asp:ListView ID="ListView1" runat="server"
onitemcommand="ListView1_ItemCommand"
onitemdatabound="ListView1_ItemDataBound">
<LayoutTemplate>
<asp:PlaceHolder ID="itemPlaceholder" runat="server" />.......
I'm currently using a ListView in my webformsapplication. This ListView generates a table with (currently) three columns. "Username", "Organization" and "Locked". These are represented with string, string and checkbox respectively. The checkbox should postback on change...
Should I use <%# Eval("Username") %> or <asp:Literal blablah> to inject the data? This is more relevant for the checkbox... It seems very "dirty" to write <input type="checkbox" id="something" <%# if ((bool)Eval("Locked") == true) /* some unknown code for outputting "checked" */ ;%> />
Or should I use another container alltogether?
I am using a listview to display some items.But sometimes based on condition I have to hide few items from the list.So how can I do this?I am using ASP.Net with c#.
View 3 RepliesI'm having a hard time coming up with a good way to number the items in my paginated ListView. The solution I was using prior to adding pagination worked fine, but now the numbering doesn't persist between pages. If the first page is 1-10, the next page will also be 1-10 and so on. Obviously, it should be 1-10, 11-21, etc.
Is there an easier way to add numbering to ListView items that I'm missing? What's the best way to do this?
I have used a label in listview whose text is bound to database.I want to show that label text in other page.How I can do it?
View 1 RepliesI have a listview that is bound to a datatable on the runtime. The listview has a <ItemTemplate> format which includes a lot of controls. On the page Load I do bind the listview to a datatable. Now, I want to add more ListView Items without databinding the whole listview and maintain the same ItemTamplate.
View 14 RepliesI have a listview with some data bound to it.
In this data are column for an address.
How would I go about accessing these data items in code behind so I can concatenate them into one easy variable and miss out columns that have no data in, i have fields:
address
address1
town
county
postcode
I don't have a problem with the concatenation just accessing the data items.
I am getting data out via a dataset and binding it to a listview.
Is it possible to access data items in the code behind to format or do whatever i want with them then showing it in the list view such as, concatenating the address fields into one variable?
so instead of writing:
DataBinder.Eval(Container.DataItem, "address") & ", " & DataBinder.Eval(Container.DataItem, "address1") & ", " & DataBinder.Eval(Container.DataItem, "town") etc...
in the actual list view i could do this in the code behind in a string variable then show the variable in the list view?
