I'm following a tutorial from [URL] to create a better menu with submenus. Does anyone know how to convert this inline code to code behind? I'm not a big fan of inline code but I have no idea on how to convert it to code behind.

I want to bind parent repeater item index in child repeater control using inline code not code behind side.
For example
[Code]....
I have a couple of Checkbox controls in the Item Template of a Repeater and am trying to set them (checked or not) based on an underlying data value. With Labels the <%# Bind... > syntax can be used but there does not seem to be an equivelent for a Checkbox.
So I have moved into the code, specifically the ItemDataBound handler of the Repeater control but cannot seem to instantiate the Checkbox controls.
In the handler repProjectList_ItemDataBound(object sender, RepeaterItemEventArgs e) I can instantiate the Repeater by casting sender or the RepeaterItem by using e.item and both have FindControl() methods but neither seem to find my Checkbox.
Further, once I am able to 'find' the Checkbox, I'm not sure how to reference the various values in the underlying data source.
i have a database of values that I am rendering in a table via the repeater control. (Previously I was using a gridview but I know require a repeater) I have a checkbox being 'repeated' for each record and I can get the id of each row to do some logic, but what I cannot get is whether it is checked or not as the value is null. As the database has no null values, I can only asume it is not binding for the checkboxes as current true values do not have a check in the box. The onCheckedChanged event carries out the logic required to change whether record is disabled via the database. With a gridview
Checked='<%# Bind ("Disabled")%>' was enough
<td
class="GridCentre"[code]....
is this done with the itemdatabound event? and how is it done?
my repeater binding repeated rows.
TableAdapters.myorderTableAdapter tblerows= new TableAdapters.myorderTableAdapter();
DataTable dt = tblerows.GetDataByUserName(username);
DataTable outputTable = dt;
for (int i = 0; i < 4; i++)
{
outputTable.ImportRow(dt.Rows[i]);
}
Repeater1.DataSource = outputTable;
Repeater1.DataBind();
from the above code i got number of rows for the seleted username. so i need to show only resulted rows. here repeater1 repeating my rows.
I'm trying to bind a value to a dropdownlist. Here how the code looks like in the aspx page...Bind the textboxes below is not a problem...but its not working with the dropdownlist..
So basically, what i want is the value selected from the dropdownlist to be remembered after i press next button and back button..
[Code]....
I have a repeater on which I need to bind the name returned by the querystring, the binding should be don on the following request : Request.QueryString("file_type")
[Code]....
basically the file type represent a foldername on the server, and this changes depending on the request
I am attempting to bind a Repeater (but it could be a GridView or ListView) to a list of objects. The List's type is an abstract type, which has two different classes derived from it, both with different properties. Because they have different properties, I cannot just have one ItemTemplate. If I bind a control to a property of one type of class and the other type doesn't have it, it throws an error.
Here's where I'm at:
I cannot use <% if (whatever) { %> some stuff <% } else { %> some other stuff <% } %> because I cannot access the databound item to make the choice based on its type. I cannot use the <%# %> syntax, which lets me use the databound information, because you cannot code logic like if...then...else. I cannot (rather not) call a function and return a string with the code because what I want to render is complex and contains further nested databound controls. Has anyone found an ingenious way of doing if it is this type of object, display these controls, else display these other controls?
What's the difference between binding for example a column called ("Name") in both cases ? and is there's any performance difference ?1- Assigning the data in the mark-up
<asp:Label ID="Name_Lbl" runat="server" Text='<%# Eval("Name") %>' ></asp:Label>
2- defining a control object for every control inside the repeater ItemTemplate and find it and then assign the data in the column "Name" to ite.Item.FindControl("Name_Lbl")
I've been using a repeater to build a website's site map page by binding to the web.sitemap file. For example, to display 2 levels of links:
[Code]....
So far, everything works well. However, in some cases, I do not want to display certain pages in the site map. I've added a custom attribute to each node (nodisplay= 'true').How can i check for this attibute, and avoid it from being displayed by in the repeater.
I have a repester like this that bind it with asp.net :
<ul class="menu">
<asp:Repeater ID="rpt_website" runat="server">
<ItemTemplate>
<li tabindex="1">
<img src='<%#Eval("Pic","Images/Portfolio/{0}") %>' alt='<%#Eval("Title")%>' width="200" height="120" class="AbsolPos" />
[code]...
now i want to bind this repeater with jquery ajax , and I use this link for bind my repeater with jquery ajax , but it does not work.
have some Objects, lets say Employee and Role defined as below and I have defined relationships in my database that gives me a list of objects say employees and thanks to my framework each employee object also has a Role object linked via the RoleIDID, UserName, Password, Email, RoleIDRoleID, RoleNameSo in code I can do something like this
Employee emp = dataService_GetEmployeeByID(1);
string RoleName = emp.Role.RoleName;
Now here is my problemI can bind any object in a repeater and it works fine for the first level in my relationship
For instance <%# Eval("UserName") %>
But I need to be able to show the details for my child objects as well (Role) so something like this (which does not work)
<%# Eval("Role.RoleName") %>
how can i get site map data from the SiteMapDataSource in codebehind same as i would if i wanted to create a typical dataSet from an XML File?
i want to create a custom menu programmaticaly and already wrote out a site map - i know i can just copy it to an xml file but I want to know if its possible to access it from a SiteMapDataSource like
SiteMapDataSource ds = new SiteMapDataSource();
//iterate through nodes to create custom controls, etc...
I am using repeater and mytemplate
<ItemTemplate> <td> <asp:ImageButton ID="btnProductImage" runat="server"
ImageUrl='<%# GetImage((Xslbay.Data.ProductImage)(Container.DataItem)) %>'
CommandArgument='<%# GetFullImage((Xslbay.Data.ProductImage)(Container.DataItem)) %>' OnClick="btnProductImage_Click" /> </td> </ItemTemplate>
ButI want to add <br /> if item index =5

I use a label for sending my html data to the view(ASP.net.). Below you see a short version of my code-behind page:
[Code]....
This practice is in my eyes not the best one. The html-code is much bigger in the real situation and I don't like that in my code-behind page. I would only send the image source to the view and bind them in some ASP.net tool. I think the ASP.net repeater is the best. But I have no idea, how to do this?
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 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
View 2 RepliesI'm so confused I wasn't even sure what to make the title so that it would make sense.
Here is what I have:
[code]...
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.
I am using Nested Repeater repeater1 and repeater2 in my project . one button is there inside repeater2 but i cant use that button using e.commandname
so how to use that button and how to write code on it.
what changed do I need to make to my code for it to achieve what I'm after.
At the moment I am getting a "cannot cast to type" error message with the below code.
I have also tried calling the ItemDataBound method in with the parent repeater tags and had no errors but when I clicked on the button it would just move back to the top of the page and would not hide or show any data. Also I have made the div style to none but the first record still shows its child but the rest don't.

somewhere on the net I found very useful example of programatically databainding the treeview control (code blow). I use this treeview as menu bar in my masterpage. It works fine but with one exception: when I click the node of this treeview I'm redirected to the correct page but after page is reloaded my treeview is collapsed and node I chose just before is not highlighted. What to do to correct this problem. Do you know better examples of programatically databainding of the treeview control? Maybe it will be better to bind data to the sitemapdatasource and next to the treeview. Then I shouldn't have to worried about this?

Regards. Pawel
in my masterpage I have the following:
<asp:SiteMapDataSource
ID="MenuSiteMap"
runat="server"
ShowStartingNode="False"
SiteMapProvider="SpanishSiteMap"
/>
In My code behind I want to provide the SiteMapProvider instead of having it hard coded from the aspx page. What would the code look like to replace in thie case 'SpanishSiteMap' and have that come from code behind in c#? I thought something like this but i know this is way off. hopefully someone has a one liner code that will give provide some sleep. I've come closer to a working code. this is what i have... but get the error mentioned below.
MasterPage myMasterPage = (MasterPage) this.Master;
// do a find control on myMasterPage and find the siteMapDataSource
SiteMapDataSource mySiteMapDataSource = (SiteMapDataSource)myMasterPage.FindControl("MenuSiteMap");
// now u have the reference to the siteMapDataSource used in the master page how do I set the provider..
mySiteMapDataSource.Provider = "SpanishSiteMap";
Error: Cannot implicitly convert type 'string' to 'System.Web.SiteMapProvider'
I have the following Page_Load function...
protected void Page_Load(object sender, EventArgs e)
{
XmlDataSource1.Data = GetXmlFromFile(Request.QueryString["file"]);
XmlDataSource1.DataBind();
Repeater1.DataBind();
}
The page in which this Page_Load resides is called by a parent page. Each time this Page_Load gets called the value of "file" in the query string will be different. So each time I will be receiving the XML contents from a different file which are inserted into the XmlDataSource and then bound against by the Repeater. Getting the XML data from the file works great but when I bind against the repeater that only works the first time through Page_Load. Each time after that when this code is executed the same results from the first XML file are displayed in the repeater.
What am I missing here. How can I get the XML data to be bound against the repeater on each page load instead of just the first one?
