SchoolIDLabel is in the ItemTemplate of the ListviewSchools. The following works for insertitemtemplate

View 3 RepliesIf there is no value in the database, I would like to hide my hyperlink within a gridview. Here's what I have:
visible='<%# Eval("my_field").Is Not Null %>'
Of course the Is Not Null doesnt work, is there something I can do to check:
1) if not null then set visible true
2) if null then set visible to false
I have a DataGridView with a ItemTeplate column, which has a HTML hyperlink (<a href....>) inside. When a user clicks on a link, a popup with a TextBox is showed to the user. Then the user can type a data. With this data, I must update the hyperlink's text in which the user clicked. All using javascript. The problem is that I don't know how to find the Hyperlink because there will be so many hyperlinks as rows in the DataGridView and they will have the same Id.
How can i find the hyperlink using javascript?
I have a Repeater displaying some data that doesn't do what I'd like to see. If a certain condition is met (ex: parent.NumOfChildren > 0) I would like a hyperlink shown. Here is what I have so far:
<asp:Repeater ID="parents" runat="server" >
<ItemTemplate>
<asp:HyperLink NavigateUrl='<%# "Children.aspx?parent=" + DataBinder.Eval(Container.DataItem,"Parent_ID")%>'
Text='View Children' runat="server" target="_self" ID="Hyperlink2" NAME="Hyperlink2"/> -
</ItemTemplate>
</asp:Repeater>
In this case, the "View Children" link shows up for every item in my Repeater, but I'd like it shown only if parent.GetNumOfChildren() > 0. Would it be correct to try setting the Visible="true/false" property of the HyperLink? Is that the norm for this sort of problem? Or, is there a way to wrap the entire <asp:Hyperlink> ... </asp:Hyperlink> tag in an if statement that has a reference to the object that is currently being interated in the Repeater? Ie:
if(CurrentDataItemInIteration.GetNumOfChildren() > 0)
{
<asp:Hyperlink> ..... </asp:Hyperlink>
}
To me, the Visible="true/false" solution seems cleaner, if possible.
using a repeater to display multiple 'comments' related to a parent database entity (a 'task' in my case). When the user creates these comments they can optionally attach a file. Now, I'm working on the page that lists these comments and I'm not sure how to go about displaying the link to the attached file, if one is present. There may not be a file. The database record that contains the comment will also contain the url to the file if one was attached.
what are my options for this? I would like to just display a link to the file after the comment content, only if a file is available.

Above is the field in the gridView. My question is very simplet that whatever the number of rows in a grid in one column, I just want to show the sum of the values of a column in the Footer Row.
I don't want to use javascript. I have tried following code but there is displaying "0" in the footer of the respect column instead of sum.

I need assistance in the code which I provided. I want something like this:
20+30+10 =60
but it is displaying like:
20+30+10=10
I have a gridview and in the gridview i have a an itemtemplatefield with a regular html hyperlink in it.
Based on the value of one of the columns in the gridview, i want to hide this hyperlink and just replace it with the value of another column
e.g. <a href="page.aspx?x=<%=Me.CurrentAgent.ID %>&id=<%# Eval("Id") %><%# Eval("Customer") %></a>
if Eval("Status") = 123 then instea of the above hyperlink, i just want <%# Eval("Customer") %>
I have various difficulties handling dropdownlist in listview itemtemplate.Hopefully, resolving this example will help me understand how to make things work.I need to do several things upon DropDownList1_SelectedIndexChanged.(1) Fetch row index of listview then set the row as listview selected, or vice versa, in which dropdownlist was changed.(2) Fetch text of namelabel in that selected listview row.(3) Fetch selected text of dropdownlist in that selected listview row.
[Code]....
At the moment...(1) Label1.Text = ListView1.SelectedIndex always shows '-1' regardless in which row dropdownlist is selected/changed.(2) Label2.Text = NL.Text pops 'Object reference not set to an instance of an object'.(3) Label3.Text = DDL1.SelectedItem.Text pops 'Object reference not set to an instance of an object'.
I want to be able to get the current bound object in the ItemTemplate of a ListView control.
Here's an example of what I want to do:
<asp:ListView ID="UserList" runat="server">
<LayoutTemplate>
<asp:PlaceHolder ID="itemPlaceHolder" runat="server" />
</LayoutTemplate>
<ItemTemplate>
//How can I get the current bound object in here?
</ItemTemplate>
</asp:ListView>
I am using a ListView and would like to implement the switch from read only mode to edit mode for a ListView item on the client side. Some of this is discussed at: Inline form editing on client side
I am trying to do this by something like:
[Code]....
switchState is a Javascript function that simply hides/shows the DIVs with the readonly and edit classnames. In LinkButtonSave_Click I get the value from TexBoxName but it always contains the bound original value and not the edited value that was entered in the texbox.
Does ASP.NET not postback the textbox value because it is in the ItemTemplate or is it something else that's causing this problem? Could I use a Repeater instead to accomplish this?
I was wondering if there is a way to hide the ItemTemplate. I am using listview and would like to hide the itemtemplate when i am inserting a new record. Im not sure how to or if it is possible to do.
View 4 RepliesGiven the following code for a textbox in the EditItemTemplate of ListView:
TextBox txt = (TextBox)ListView.EditItem.FindControl("ImageURLTextBox");
How would we code for a textbox in the ItemTemplate of the same ListView?
The following code represents an EditItemTemplate in my ListView. My problem is that when I click the Update button, everything updates but then the display doesn't go to the ItemTemplate. According to Microsoft: "By default, theListView control returns to read-only mode after an update operation."
[Code]....
I have listview where every item has a textbox and next to it a button if you want to update the item. I want that every textbox default button(pressing enter) is the one right next to it. So i have a panel(pnlInput) surrounding the textbox(txtQuantity) and the button (btnCart). If i do nothing in code behind the default button for every textbox is the button of the item that was first rendered.
But then i tried in codebehind
lstArticles_ItemDataBound
//Set default button right
Panel tmpPanel = (Panel)e.Item.FindControl("pnlInput");
Button tmpButton = (Button)e.Item.FindControl("btnCart");
tmpPanel.DefaultButton = tmpButton.ClientID;
But when i tried that i get the execption when the page is rendered that the default button for a panel needs to be of type ibuttoncontrol. I also tried UniqueID, but the same happens.
on SelectedIndexChanged event handling of DropDownList in ItemTemplate of ListView. I put OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged" in mark up, with code behind, but only to get Compiler Error Message: BC30456: 'DropDownList1_SelectedIndexChanged' is not a member of 'ASP.webform1_aspx'. How do I make it a member? When I do not put OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged" in mark up, BC30456 does not pop up, but nothing happens when dropdownlist selected item is changed.

I've got the following ListView (extra code removed for clarity) :
<asp:ListView ID="lvParticipants" runat="server" DataSource='<%# Eval("Participants") %>' >
<ItemTemplate>
<asp:Label ID="lblHomePhone" runat="server" Text='<%# Eval("HomePhone", "{0:(###) ###-####}") %>' ToolTip="Home" />
</ItemTemplate>
</asp:ListView>
This does render the phone number, but it is unformatted (8005551212 instead of (800) 555-1212).Why is the formatting not applied?

View 4 RepliesThis is a weird issue. I have a List view with 2 Link buttons. "Edit" and "Delete" Iam able to attach an event handler for the first linkbutton(Update). Code in the event handler executed fine. But If I try to attach a event handler for the second link button(Delete) , I get an error.
My Item Template Looks like this.
[Code]....
First Item works absolutely fine. But If I attach the second handler, I get the following error
Am I missing some thing ? Note - There is no error if I try to attach the 1st event handler to the second link button.[ie EditLinkButtonClicked to DeleteLinkButtonClicked ] Issue occurs only when I try to attach DeleteLinkButtonClicked to DeleteLinkButton
I'm trying to do a relatively simple thing, but just cannot get it to work. I'm trying to find a dropdownlist within a ListView ItemTemplate within Page_Load.
This is the code

And this is the C#

I have also tried without this > this.ListView1
I have this listview
<asp:ListView ID="ListView1"
runat="server"
onpagepropertieschanging="ListView1_PagePropertiesChanging"
onitemdatabound="ListView1_ItemDataBound">
[Code]....
What I want is to be able to click on the button: btnAddCart and then in the code behind retrieve the value of product name (Eval("Prouct")) and price (%#Eval("Price","{0:#}")%) for that particular row/itemtemplate.
I have a listview showing the data, and that i will use to Show, Edit, Delete, and Insert data.
I added a ASP.NET Ajax HTML Editor to the EditItem Template.
I click on EDIT button and it turns into the EditItem Template, i modify the data and when i click UPDATE it does nothing.
Neither updating data or turning back to ItemTemplate.
Here is its code:

And the Code behind:
