I have an ASP.NET page that has a code-behind method that is defined as follows:
[code]....
Essentially, when the TicketStatusID is bound, I want to call back to GetStatusColor and display the result of the method instead of the actual ID. How do I do this in a Repeater?
I had a web application that was binding a IDataReader to a repeater control. I converted the project from 3.5(2.0) to 4.0 and then I received the error:
An invalid data source is being used for rptData. A valid data source must implement either IListSource or IEnumerable.
So, I used a datatable instead and the binding worked. So it seems that they have removed this functionality with .NET 4.0.
I'm hitting a wall trying to format a boundfield of a gridview. I've tried suggestion about setting the htmlencode to false, but that didn't make a difference.The column I am trying to format is:<asp:BoundField DataField="FromDate" HeaderText="Start Date" DataFormatString="{0:MM/dd/yyyy}" HtmlEncode="False" />
View 1 RepliesI have a generic list of a custom type. The custom type has a string and double.I'm binding the list to a gridview and it outputs everything fine.I'm trying to format the double column into a currency format. It is in a template field as I'm calculating a running total. I pass the value to a function that returns a double and adds the current value to a running total which I will show in the footer.
The format is not changing to currency as expected when using String.Format("{0:c}", GetTotal(Convert.ToDouble(Eval("Amount"))))
I have a bound column.
<asp:BoundField DataField="WorkPreference" HeaderText="WorkPreference"
HeaderStyle-HorizontalAlign="Left">
<HeaderStyle HorizontalAlign="Left" />
</asp:BoundField>
dr["WorkPreference"] = sa.WorkPreference ( This is how I bind the data to a DataRow)
The example of the data which gets bound to this column is like the following:
Communications and Marketing Officers; Environmental Assessors; Geologists and Geosciences; Geospatial/Spatial Information Officers;
What I want is that the data should be presented to the user like the following:
Communications and Marketing Officers
Environmental Assessors
Geologists and Geosciences
Geospatial/Spatial Information Officers
In short: I basicaly want to put a break where there is a colon and then bind the data to the gridview. It looks like simple but if you can let me know.
to format Amount in 00,00,000.00 in Bound Field of gridview?
View 8 RepliesI have what's bound to be a stupid question, so I'll apologize for what I think should be an obvious answer my brain just can't see. My problem is very simple. I have a Repeater control bound to a SqlDataSource. The ItemTemplate in this case is one complicated beast, and rendering can take a loong time if too many records are returned; so I need to maintain tight control over how many records are brought back from the data source.
Is there not some way of either stopping the creation of subsequent RepeaterItems once a certain count has been reached, or cancelling the bind if more than a certain number of records are returned? I know I can grab the record count from the AffectedRows property in the Selected event of the DataSource, but I've encountered a brain-lock on how to stop/inhibit the binding (or RepeaterItem creation beyond x records).
I'm happy with either aborting the binding altogether if the record count is too high (displaying no records), or simply stopping it after X records are returned; at this point, I'm not picky. Either way would work, and it seems I ought to be able to readily figure out either one, but my brain has simply gone into neutral.
I have a detailsview bound in the code behind file. I want to format the column headers. How can I do that in the code behind file.
SqlCommand Cmd = new SqlCommand(SQLquery, connection);
SqlDataReader Dr = Cmd.ExecuteReader();
dvEstQty.DataSource = Dr;
dvEstQty.DataBind();
Cmd.Dispose();
connection.Close();
connection.Dispose();
I have an ASP.NET web form that uses an ASP.NET Repeater. The data source for this repeater is a DataTable that includes a column called "City", and one called "State". In the ItemTemplate of the Repeater, I want to call a custom method I've written called "FormatLocation". This method is defined as:
protected string FormatLocation(string city, string state)
{
string location = city;
if (state.Length > 0)
location += ", " + state.ToUpper();
return location;
}
I want to call this method when the data is bound in the ItemTemplate so that the result appears in the UI.
I have to set a LinkButton's OnClientClick attribute but I don't know what this value is until the LinkButton is bound to. I'm trying to set the value when the repeater binds, but I can't workout how to get the 'boundItem/dataContext' value.
<asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate>
<asp:LinkButton Text="HelloWorld" ID="Hyper1" runat="server" OnDataBinding="Repeater1_DataBinding" >
</asp:LinkButton>
</ItemTemplate>
</asp:Repeater>
protected void Page_Load(object sender, EventArgs e)
{
var list = new List<TestObject>();
list.Add(new TestObject() {TestValue = "testing1"});
list.Add(new TestObject() { TestValue = "testing2" });
list.Add(new TestObject() { TestValue = "testing3" });
this.Repeater1.DataSource = list;
this.Repeater1.DataBind();
}
public void Repeater1_DataBinding(object sender, EventArgs e)
{
var link = sender as HyperLink;
//link.DataItem ???
}
Is there anyway to find out what the current rows bound item is?
I'm using a repeater to list some data from a DB.One part of the data is of Type Money, which shows up as 29.9900
how do I format it after evaluating it? or should I be formatting it prior to evaluating it?(also perhaps prefacing it with a $ sign)
In the code behind I have a function that returns a List(Of SomeClass):
rptRepeater.DataSource = SomeFunction(SomeVariable)
rptRepeater.DataBind()
<%#Databinder.Eval(Container.DataItem, "Parameter1")%>
How can I format my date field like this "Jan 6 @ 7:42 AM" from my date field. My present date field is in this format "1/6/2010 7:42:00 AM".
I am using this in my repeater control.
I tried to figure this one out trying a lot of different format strings so now I am asking for help .
Here is my code :
[Code]....
I tried Eval("SSN", "###-##-####"), "999-99-9999".
explain reasons why the name property of a Repeater control's child controls would be generated differently in an ASP.NET application when it is deployed on different IIS servers?
One some IIS servers the Name is generated using the format:
String.Format("{0}:_ctl{1:00}:{2}", RepeaterControlID, itemIndex, ChildControlID);
e.g.
<input name="Mntc_Software_List:_ctl1:id" id="Mntc_Software_List__ctl1_id" type="hidden" value="1772" />
and on other IIS servers the format is:
String.Format("{0}$ctl{1}${2}", RepeaterControlID, itemIndex, ChildControlID);
e.g.
<input name="Mntc_Software_List$ctl01$id" type="hidden" id="Mntc_Software_List_ctl01_id" value="1772" />
protected void Page_Load(object sender, EventArgs e)

I have nested a repeater control in Gridview. Right now it is showing gridview rows and repeater header for every case(whether data is there or not for that particular grid view row in the repeater control). I want to hide the gridview row and repeater control header when there is no data present for that particular gridview row. That case I handled at code level by filtering the resulted data table.
Now the another problem I am facing: I have allowed the paging on the gridview i.e. pagesize 3. When page loads it works fine, but when I go to page 2 then it generates following error: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
Below is the code to fill the grid, paging and fill repeater on rowdatabound event of grid.

got an example of a repeater inside a repeater (dataBound) code behind?
View 3 RepliesI have a user control that displays a shopping cart in an ecommerce application.
The main cart display is a repeater that renders as a html table. In one of those table columns, there is another repeater to display people associated with the products int he cart (it's a repeater in case there is a line item >1 with multiple people).
I've added an ImageButton that I want to use to change the person associated with the item. At first, when I'd click on it I was getting this error:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
So as an experiment I disabled EventValidation on the page (not the control it's self) and now I do not get an error, but I also do not ever hit the breakpoint I set in the innermost repeater's ItemCommand event.
So I wonder how I might do this without disabling EventValidation, because this control will show up on multiple pages and we don't want to edit them all. Also, I'll need to know not only the repeater containing the control's row that the event came from but also the row index of the repeater containg this one. Is this possible?
I have a text field that users enter information into a database (SQL Server). They are entering as little as a few sentances to multiple paragraphs. I can successfully display the data on my webpage, but the text field is not formatted very nicely. The output is all smashed together like one big paragraph. Ironically, when I also display the text as a tool tip it outputs as multiple paragraphs like it was entered. How can I format the output in the datalist to create a more readable text field? My datalist field is as follows:
<asp:Label id="WebDescriptionLabel" runat="server" Text='<%# Eval("WebDescription") %>' ForeColor="Brown" />
I have repeater in which I have 2 hyperlink in the footer of the repeater and I want that the hyperlink can navigate from the page_load

I want to bind parent repeater item index in child repeater control using inline code not code behind side.
For example
[Code]....
I am using a repeater to build a custom table. However, I can't figure out how to make the table show subtotal if the next rows tour does not match the previous rows.
Something similar to that.
row1 tour1
row2 tour 1
tour1 subtotal
row3 tour2
row4 tour2
subtotal
total
[code].....
but this shows all the data in the nested repeater not the ones that match the parentrepeater fields for example tour,theme,dep7 should match in the child repeater
I'm so confused I wasn't even sure what to make the title so that it would make sense.
Here is what I have:

I have links at the top of the page that are the letters A-Z. What I want to do is click on one of the letters, then show only the div IDs that start with that letter. I can't figure out how to do this since I'm dynamically creating the ID names. I had it set up nicely with Javascript and CSS, but the function call was inside the repeater. The layout is changed now, and I don't understand how to make the div ID available outside the repeater.
