I have a ListView with an ItemTemplate item as below:
<asp:Label runat="server" ID="lblChangeOrders"><%#Eval("sum")%></asp:Label>
What I need is if the sum is negative I need to set font color as RED and remove the minus sign.
I am simply trying to change the listView template based on a value in the listview data. I do have this displaying the information correctly. Except when I try to change the item template based on a value in the listview. My code is below ....
View 6 RepliesI'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?
I want to have a listview with conditional formatting on its edit and delete button.So, in nutshell, I want to check if the writer of post is equal to session("memberid"), then the edit and delete button will be appeared, else, it will show hidden.

roughly, i want and plan it to be sort of like that (as i found it at [URL]But I do not have any idea on how to make it whatsoever.So, if you guys have any idea (same as method above or different method), please show me the way.I have seen another forum, but I don't get it.
I am trying to change GridView Row formatting based on cell value. I am using GridView's Rowbound event. It works when Caching on SQL datasourceis disabled but when caching is enabled it doesn't seem to work.
View 1 RepliesI have a gridview containing serial-numbers.
I would like to format the background each data-row that contains a duplicate serial-number value.
I'm planning to do this using a DataBound event handler.
So, in English:
Set background colour of THIS_ROW to red where the Serial_Number of THIS_ROW is the same as the Serial_Number of ANY_OTHER_ROW.
All rows with duplicate serial-numbers would be red.
I'm not sure how to write the code for this event.
The gridview is bound to a SQL datasource. Getting the dupes in SQL is easy:
SELECT Serial
FROM Table
GROUP BY Serial
HAVING (COUNT(Serial) > 1)
is it possible to do something like this: Having a listview in my web form to calculate employee's salary, just about around 1000 employees at a time, but due to many conditions to calculate one's salary, the page cost too much time to load the data (about 25s-30s), now it's just nearly 100 employee, but if about the above number of employee (and it will be even more in the future), it will be unbelievable slow,
so I think of a solution like this, the page still load but it just calculate 20 employees at a time and bind it to the listview so the user can see some data to not see it's too too slow to load the page, and after that the page still loading to calculate the rest and bind data to the listview again and now it is 20 + 20 +........ = 40, 60 rows....... (the listview won't reload it just add new rows) I remembered that I saw something like this in Bing.com when load the image searching, and some asp.net gridview have the exact ability as Bing, the grid/lisview load data when user scroll down, but now I can't remember the link and the key words to search for it.
I used LINQ to retrieve data, I did compiled query, and some tweaks to improve performance already, yes, it so much faster than the first time but it still so slow after all.
Note: I have read about loading content while scrolling or scrolling continuous but it not load all the data one by one and bind the data to the listview, it just continue to load the data when user scrolling down and there is no end to it.
I have a function that constructs a datatable from a file that the client uploads. And I want to bind that datatable to a listview but I'm not sure what I'm doing wrong... Say, the datatable is like:
FirstName LastName
John Smith
Here's how my aspx looks like:
[Code]....
In my names.aspx.cs file, I do: lvNames.Datasource = dt; //dt is a datatable
lvNames.DataBind();
When I run my aspx page, the listview is empty, is there something obvious I'm doing wrong?
I'm using a listview control to show a list of categories/subcategories
<%# Eval("SubCategory1")%> When the user clicks the SubCategory1 link, the list view should fill up with the next subcategory, SubCategory2. The problem is off course that <%# Eval("SubCategory1")%> is hard-coded. I need it to change to <%# Eval("SubCategory2")%>...and so on, as the user is drilling down into the sub-categories.
So is there a way to change <%# Eval("SubCategory1")%> dynamically?
Am trying to bind data to a dropdown list on pageload based on a condition. Code explains further below.
public partial class AddExhibit : System.Web.UI.Page {
string adminID, caseIDRetrieved;
DataSet caseDataSet = new DataSet();
SqlDataAdapter caseSqlDataAdapter = new SqlDataAdapter();
string strConn = WebConfigurationManager.ConnectionStrings["CMSSQL3ConnectionString1"].ConnectionString;
protected void Page_Load(object sender, EventArgs e) {
adminID = Request.QueryString["adminID"];
caseIDRetrieved = Request.QueryString["caseID"];
if (caseIDRetrieved != null) {
CaseIDDropDownList.Text = caseIDRetrieved;
//CaseIDDropDownList.Enabled = false;
} else { try { CreateDataSet();
DataView caseDataView = new DataView(caseDataSet.Tables[0]);
CaseIDDropDownList.DataSource = caseDataView;
CaseIDDropDownList.DataBind(); }
catch (Exception ex) {
string script = "<script>alert('" + ex.Message + "');</script>";
} } }
The CreateDataset method that is called in the if..else statement is contains the following code.
private void CreateDataSet() {
SqlConnection caseConnection = new SqlConnection(strConn);
caseSqlDataAdapter.SelectCommand = new SqlCommand("Select CaseID FROM Cases", caseConnection);
caseSqlDataAdapter.Fill(caseDataSet); }
However when I load the page and as usual the condition that is supposed to bid the data is met, the gridview decides to displays as follows. Is it me or its the Datagrid?
I don't know what I'm doing wrong but for some reason I'm not able to maintain the index selected value on the listview that I've created within a user control. In a user control I have added a listview. I have exposed the handler, Datasource and DataKeyName. I have populated the datasource of the listview by using the following:
MYLIstView.aspx.cs - user control
[Code]....
I am using Datalist to bind userdetails which contains department name. With RepeatColumns="2" & RepeatDirection=" Horizontal". Now i want to check a condition while binding.for Example; If i am binding with 5 users having 3 users with same department and remaining 2 users with different departments then i want to show 1st 3 users having same department in two rows and remaining to users in next two rows.
<asp:DataList ID="dlHaysContacts" runat="server" RepeatColumns="2" RepeatDirection=" Horizontal">
<ItemTemplate>
<div class="dlSettings">
<div>
<asp:LinkButton ID="lnkHaysContactName" runat="server" Text='<%# Eval("HaysContactName") %>'

and iam binding the Gridview with Data Table it is working .Now i have to make some thing visible and Invisible based upon some Value like below
Datatable dtTable = (Viewstate)["StatusData"]; // Same Data Table which is Data Source of Gridview Control

Where Status.Open is an integer Enum value like Open = 1 and Close = 2 .row["Status"] is the Text Open and i want to compare with integer valueHow i compare the Values ? i have to use the same Data table or not?
I'm using VS2008. When a dataset is bound to the DataSource of a ListView, SelectedIndexChanged event does not fire. If I used DataSourceID instead, it has no problem. But SelectedIndexChanging event fires for both.
why and how I can get SelectedIndexChanged event fired when DataSource is used?
I have a stored procedure which is returning me several rows. I am presenting the rows as item in a repeater. I need to move one of the rows down to the footer template, based on a condition. For instance, if my stored proc is returning a column called A, I need to drop this record to the footer item, if the A column value is Total. I have no idea how to do that.
View 2 RepliesI'm using an edittemplate to handle both editing and inserting for a Formview. In Insert mode, the Identity parameter is not needed (and cannot be used in the parameter list). In Edit mode, I need the bound value to know which record to update. So, what I tried to do is set the Text property in the OnDataBinding method.
[Code]....
The result is that the field is bound for Insert anyway, shows up as a parameter, and my insert statement fails (since this extra field messes up the field order of the parameters). Plus, it is always null in Insert mode by definition.
Is the OnDataBinding method too late to clear the property? If so, where can I do this, since PageLoad is too early (the template has not loaded yet and I cannot Findcontrol the field. Or is there a better way to handle all this?
I want to toggle a Textbox to be visible (true, false) contained within an InsertItemTemplate based on the data being Null/Empty.
It Works in the Item Template since it is calling the "select parameters", but once it is in the "insert parameters" on databinds, I am unable to get this to work.
<%# String.IsNullOrEmpty(Convert.ToString(Eval("qu_8")))?Convert.ToBoolean("false"):Convert.ToBoolean("true") %>
(works in Item Templates, but not in InsertItemTemplate to toggle a textbox to be visible or not visible). I am using C# in code behind.
I need to bind a List control based on the Gridview Row's datakeyName value while the Gridview control is being loaded into the page. I tried the following but it does not work.The BulletedList control is nested inside a Gridview Control and they both bound to an ObjectDataSource control. In my code, I passed teh UserID into the UserID parameter and call the Select() method but still does not work. Basically, I want to list of a user's hobbies, therefore the hobbies control are driven by the userID. tell me how can I get it to work?
protected void UserGridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
int UserID;

I have no clue what I'm doing wrong here, but I wanted to create a grid view based on a return from a tableadapter.
[Code]....
[Code]....
Also, maybe I should be going about this another way as I wanted to add a drop down to each record and a link to each record.On pointers on how I should do this would be great too.
I come across the technique on how to apply a different CSS class to make a row stand out from the others. However, the original code is for gridview whilst I am trying to get it works on a listview. The original code for the gridview is as follows and how to get it done on listview.

I'm doing research on framework development for my company. SInce I will be developing a framework I can not simply declaire all my control in the code in front. Receiently I've been having trouble binding the controls from my ListView to my ObjectData Source. Basicly the properties in my DataObjectTypeName are not populated when the ObjectDataSource "Update" command is thrown. I recieve no error, I just get null values. All I need is an equivalent to this statement for code-behind ...
<%# Bind("AbstractText") %>This would solve all my issues. Ofcouse I will most likely need to bind the control's ID somewhere but that is not an issue. How do I Bind a control to a property in my DataObjectTypeName from the code-behind?
Listview and objectdatasource binding?

I have a ListView that does quite a heavy query. I don't want the user to have to wait half a second to a second for the page to load. I would much rather have the page load, display the theme and then have ajax make a call to the server to run the query and bind the listview while a loading icon is displayed.
The only thing i can think of is to use the sys.application.init handler to add some javascript that calls dopostback and passes a command name. I dunno... any thoughts? Anyone do this with aspnet/ajax with update panel? I guess im trying to bind an update panel without requiring a user clicking a button.
I have a class that returns a list of "Category" Objects. I'd like to display them along the left-hand side of the page in a listview (if that's the best way to do it, even).
The category objects have normal attributes. Title, User, NumberOfProjects. I'd like to display both the title and the number of projects in this list.
Not worried about editability right now as we might make that separate (i.e. not in-line in a list view edit mode).
I have a list view with a label that shows "Step #x", another label with the instructions, and then 2 linkbuttons for editing or deleting. At the footer of the ListView is another button "Add New Step" which opens up an empty TextBox and two buttons to save and cancel. I would also like it to increment the label, but I can seem to find the control in the code behind to change it's text. How do I do this?
Here's the asp markup:
<asp:ListView ID="lvSteps" runat="server" DataSourceID="ldsProcessStep" DataKeyNames="ID" InsertItemPosition="None">
<LayoutTemplate>
<div><asp:PlaceHolder ID="itemPlaceholder" runat="server" /></div>
