C# - Get Array Of Data Out Of Container.DataItem?
Jul 29, 2010
I have a ListView in which i have a function that creates images for users. I pass userGender,userImage1name,userIsImage1Aprooved values to the function in which i generate image.ie. if user has approved image i return it back, otherwise i return default image based on gender.y question is, is there any way to avoid passing 3 parameters to that function and to pass whole DataRow so i can get values of columns i need?In reality i pass about 12 parameters just made it easy for you.ie. i want to achieve something like that <%# GetImage(Container.Item) %> while in GetImage() i would be able to access Item("some_column_name") or C# version Item["some_column_name"].

I'm trying to populate the DataPager using Container.DataItem (I'm not allowed to use FindControl) but I get this error
'System.Web.UI.WebControls.DataPager' does not contain a definition for 'DataItem' and no extension method 'DataItem' accepting a first argument of type 'System.Web.UI.WebControls.DataPager' could be found (are you missing a using directive or an assembly reference?)
The code:

I want to pass the current dataitem to a method and check if it's valid then show a button.
This <% %> is located inside a repeater.
<%
if (Validate( (Order)Container.DataItem))
{ %>
<asp:button text=edit>
<% }%>

input type=..... value="<%= ISO3166CountryList.GetCountryByCode("IE", CurrentLocale).Name %>" />
I'm looking to replace the hardcoded IE with something like
<%#(Container.DataItem as PhoneNumber).ISO%>
No variations of what I've tried worked. How can I get a databinded value when within a <%= code block? Do I need to use an intermediary variable?

I am collecting user roles into a single dimension string array.
I have a repeater that its source set to that array. The repeater template includes list of checkboxes for the values in the array.The checkbox text is set to: Text='<%# Container.DataItem %>'
All is good till this point.
But I am trying to call a javascript function triggered by clickign a checkbox and pass it the container.dataitem, but the javascript doesn't seem to be reading the value and either complain about string not being in correct format or that treats the container.dataitem as a liter. This is the trial that didn't work (I tried many different things too):
DetermineVal(<%# DataBinder.Eval(Container.DataItem) %>);
determineval is my javascript function
Can I do that with a single dimension array?

I'm trying to pass a string value to a javascript function from a LinkButton's OnClientClick event, but the function is receiving "<%# Container.DataItem %>" instead of the value. Here's the code:
OnClientClick="javascript:SaveQuotaGroupCode('<%# Container.DataItem %>');"
The container is a collection of strings. Why is it not evaluating?EDIT: This is located in a nested ListView. The datasource for the inner ListView is a property in the datasource of the outer ListView.

I am trying to access the current 'active' top level node from a sitemap repeater from outside of the ASP.NET repeater used to render it, this is for CSS styling purposes as I want to place the child nodes on the subsequent row with different styling horizontally. At present I have the following code which I can't get to display correctly using CSS.
[code]....
I would like to display the child nodes on the next light blue element which I can do perfectly well from a seperate div if this was not rendered using a child repeater. In the image below Blog and Services are top level nodes and their subseqent nodes (2 for each) should be displayed on the light-blue row below. Is this possible?

Using an objectdatasource I would like to pass an entire DataItem to a function, within a databinding statement. I have found a way that works, but I don't like the look of it. ;-)
Lets say I have a class called "People", with two properties "firstName" and "lastName". I have an objectdatasource which returns a list of "People", and I use that to populate a Repeater.
I also have a function called "GetFullName", which takes a "People" object as it's parameter, and returns the lastname and firstname with a comma between them.
In the ItemTemplate of the repeater, I could do this:
<%# GetFullName(CType(Container, RepeaterItem).DataItem) %>
-but it looks like such a hack. (Doesn't it..? Maybe it's just me.)

I need to know what would be the best choice of array to use given the following specifications. This array's size will be predermined upon the loading of the appication. All I want to do is be able to add values to this array and replace preexisting array items with new values without the array changing size. Someone suggested that I use a Dictionary Array Object? I would appreciate any suggestions.

I use a ItemDataBound for a repeater.But i use 2 kinds of linq querys to bind it.Some of them has a MerkID, and some doesnt have this item.So its easy i need to do this:
if(e.Item.DataItem.Contains("MerkID"))
{
//Code for linq query 1
} [code]...
So of course the if selection doesnt work, but how can i do that? I already tryed this:
DataRowView drv = (DataRowView)e.Item.DataItem; if (drv.Row.Table.Columns.Contains("MerkID"))
But that doenst work because he cant convert it to a datarowview because its a linq class.So what to do? Right now i use a try and catch, but there are better solutions i guess...

I have sqldatabase tables.I am reading table data and putting in a tabconatiner(wth tabs containing textbox, checkbox etc) specific to a client. If a client has more than one row i want to iterate through the rows and read each row data. Basically I want to use a button-click to read the next row data at put it in the tabs and so on. I used sqldatareader and a while loop.I can read the data but while loop iterates through the rows and show the last row data / i want to use a button to go to the next row and show data.
SqlDatareader reader=null;
reader=cmd.ExecuteReader();
while(reader.Read())
{
txtboxName.Text=reader["Name"].ToString();
}
protected button_Click(Object sender,EventsArgs e)
{
//I want to read row data in this button click
