C# - How To Set A Table Row Color In Repeater Based On The Values Databound
Jun 25, 2010
I have a repeater control:
[code]....
There are more columns in that grid, but I've slimmed it down just for the question.
Now, what I would like to do is change the tr's background color based on the price amount. If it is within different levels, I would like to change the rows background color correspondingly.
Do I have to do this with javascript or is there some way I can get access to the table rows in the code-behind to set this color?
I am doing a data warehouse project.I have two tables tblA (id, type) and tblB(city, no_crimes, type).I want to create (insert) a number of rows based on the value of no_crimes.For Example, in tblB(Leeds, 2000, murder). SO, I need to insert 2000 rows into tblA by a single INSERT statement (not 2000 statements).
isn't present databound event on asp repeater server control?I just want to bind all my data, and at the end creates a new ItemTemplate and add it, but just when is all data binded
For the solution, I cannot use any postback methods, because this is all working through ajax. The solution need to be implemented in the asp.net code. I have a List<WebPage> that contains a list of Links (List<Link>) and I need for all the links to bind repetitive information such as page title, id, url. Here is my current repeater.
<div id="result"> <asp:Repeater runat="server" id="results"> <Itemtemplate> <asp:Repeater runat="server" datasource='<%# Eval("Links") %>'> <Itemtemplate> <tr class="gradeX odd"> <td><%# Eval("Id") %></td> //property of WebPage (part of results repeater) <td><%# Eval("Title") %></td> //property of WebPage (part of results repeater) <td><%# Eval("Url") %></td> //property of WebPage (part of results repeater) <td><%# Eval("URL") %></td>//Property of Link <td><%# Eval("URLType") %></td> //Property of Link <td><%# Eval("URLState") %></td> //Property of Link </tr> </Itemtemplate> </asp:Repeater> </Itemtemplate> </asp:Repeater> </div>
I've got a repeater bound to a datasource through the code behind. Everything is working fine so far except for this, I'm trying to concactenate a bound field as the id on a query string to an image handler:
Currently struggling with a problem that I've encountered variations on in the past. At the moment a worthwhile solution escapes me, but it seems such an obvious issue that I can't help wondering whether or not there's a "best practice" approach I should adopt.Without code, here's the issues in a nutshell:
page has databound control (a repeater) which isn't populated until user inputs data and clicks a button.Repeater item template contains a buttonUser clicks button, page posts back. On load, the repeater is actually empty so event is never handled because the originating control no longer existsGo back to the beginning of wretched cycle I've confirmed that this is the problem because if you provide the repeater with some static data on page load, everything works fine. But of course that's no use because it has to be populated dynamically.Is there a commonly approved way round this headache? I can store the data in session and re-use it on page load, but it seems terribly clumsy.
I have a Repeater and an update button inside the repeater
[Code]....
When I run this databound control to wire a javascript function it clears the viewstate and I don't get itemcommands. When I remove the button attributes command it works.
[Code]....
Obviously I can find a more creative way to add the javascript function, but this was the clearest way. Can anyone determine why adding an OnClientClick even in the ItemCreated would cause viewstate to fail?
I would like to count the number of page views. I am able to use the global.asax file and a label to obtain this. However, this gives me the total count of the page. That is great, however I like to count the number of users accessing the page when the user clicks on a particular gridview row value from the previous page.
I have a gridview in the gridview a value that links to a new page. This new page contains the row values. I would like to count the number of users who have accessed this new page based on the gridview row value. As such the page count will be different based on each row.
I'm working in a web application and my page is using a databound formview control. When i first enter the page via my code, I am unable to retreive a value from any of my controls -e.g. when i debug, i see that tbDate.text has no value (see code below). How can I retreive the values from the controls on my page e.g text boxes?
Code:
if (!this.IsPostBack) { TextBox tbDate = (TextBox)FormView1.Row.Cells[0].FindControl("txtDate"); }
I have a series of linkbuttons that are generated dynamically inside a repeater.
I need the background color of the selected linkButton to change and remain a new color when clicked. I thought that the ItemCommand property of the repeater would do the trick, but it doesn't.
I have repeater and I am using foreach to go through each row, checking for specific value and assigned the label accordingly. However, when there is a value that is not expected, I would like to highlight the whole row on yellow color.
How can I set only for specific row in repeater with different background color?
I am trying to add the alternating row color to an already existing repeater control. All I have added was the <AlternatingItemTemplate> and code inside.
I am using repeater control in my project and I have made its rows clickable by javascript, when I click a row it changes its background color.
My problem is that when ever i click any server side control in the page the color of the selected row disappear. Can Anyone has Idea to retain the background color.
I would rather specify fields in my code behind than embedding them in the .aspx page.
I also have a subtotal label control in my repeater that I would like to populate its text property by mutiplying two of the database values e.g productprice * unitprice shown in my repeater.
I need to do this in code behind, looping through the repeater. Any idea of how I can do this in C#?
Let's say I have DropDownList ddlRooms bound to the datasource which returns list of available rooms from table tblRooms. On the other hand I have users, and their info is stored in table tblUsers. Using FormView frmUsers can be inserted, edited and updated... frmUsers is be bound to separate datasource. To each user, I would ilke to assign a room, so the value of txtUserRoom will be populated based on the selected value from ddlRooms. How can i pass the selected value of ddlRooms to txtUserRoom while keeping txtUserRoom stil bound to user datasource? Do I need two separate fileds or can i just put value of ddlRooms into datasource user?
I want to compare column index 1 and column index 8, and if 8 is bigger then 1 it should be a different font color.
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) If e.Row.RowType = DataControlRowType.DataRow Then Dim x As String x = e.Row.Cells(1).Text Dim y As String y = e.Row.Cells(8).Text If Convert.ToInt32(x) <= Convert.ToInt32(y) Then e.Row.ForeColor = System.Drawing.Color.Blue End If End If End Sub
