I have a label in a template control i want to make have the addition of two databinder items
something like:<%#DataBinder.Eval(Container.DataItem, "something1") + DataBinder.Eval(Container.DataItem, "something2") %>'
but the addition doesn't seem to work - is this possible with some other syntax?
I have a formview with various templates set up for a database that has 255 columns. I need the insertitemtemplate to pre-fill values based upon a specific selection by the user (just like the edit item template) but when the template is switched to insertitemtemplate every text box is cleared. The idea is that a new entry is usually made by making minor changes to an existing entry. With 255 fields I don't want to require the user to enter every field when only three or four need to change.
View 8 RepliesI have a gridview which the columns are created programmatically.
When a button is click i will clear all columns and add the columns that I want. Im adding a boundfield which is not a problem. When I add a template field, I must add also the item template which is my problem.
How can I add a item template in the template field I created which is binded in my datasource. Also what event handler should I use to do this.
Here's the part of my code:
[Code]....
Someone know how can I bind a label item template from the datasource. The label item template should be firstname + middlename + lastname.
If im not doing it programatically, it will be just concatenating eval(). But how can create item template and bind it programmatically?
i already have a DataList, and i get any information from the rows i need by adding code such as:
[code]....
Well what i am doing there is using the values from the items that the DataList has obtained from the rows, now, what i need to do is EXACTLY the same, but for the FormView, i realised that this code does not work for the FormView, but only DataList control.
give me the code for doing exactly as shown, but for the FormView control.
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:
<asp:Image ID="Image4" runat="server" BorderColor="#E5E5E5" BorderStyle="Solid" BorderWidth="1px"
Height="100px" Width="100px" ImageUrl="'~/ImageHandler4.ashx?Id=+'<%# Bind("ImageID")%>'"/>
What am I doing wrong?
I have a simple databound dropdownlist. On top, I have a default selection, '--Please Select--', followed by another default selection, '-- Other --'. Here's the script:
[Code]....
Now, my user wants the '--other--' selection to appear on the BOTTOM of the dropdown as opposed to right sfter '--Please select--'. How do I accomplish this?
how do i check if a bit value is true or false and if false, then write another value.
Here is my code
<%# DataBinder.Eval(Container.DataItem, "gp_referral").Equals("False")?"":"xxx"%>
Am trying to check if gp_referral is false, and if so then write xxx, but in my code, whether true or false it evaluates to xxx
last year I inherited a webapplication that seems to refuse to run on a new hosting company's servers due to a "security violation"... Our old host was bought out and now sucks...So I uploaded the code to the new company - looking forward to some sleep and found that my life was about to get more complex.. I go the good old generic security error
System.Security.CodeAccessSecurityEngine.ThrowSecurityException(Assembly asm, PermissionSet granted, PermissionSet refused, RuntimeMethodHandle rmh, SecurityAction action, Object
The biggest issue was that it didn't say where the error was.. Digging deeper (taking the code appart one block a time) the error was being triggered by the followin itemdatabound event. My host says it is because they are running under medium trust, but I am not seeing why this block should cause issues. Any help very much appreciated.

I want a javascript on a databound row to act on another control in the same row - show/hide for example. The classic ASP approach was to number the controls (usually by rowIndex so that they're easier to reference. I am wondering is there a way to do this in ASP.Net without writing any item command code?
So for html to render as follows
<div onClick='actOnX0'> <span id=x0>i am x0</span></div>
<div onClick='actOnX1'> <span id=x1>i am x1</span></div>
<div onClick='actOnX2'> <span id=x1>i am x2</span></div>
Can I insert the numbers using a databound property that returns say the rowIndex / item index of the current row?
Is it possible to access a databound item via a codeblock?For example, I am attempting to add code within an itemTemplate while the current level is not equal to the previous level.
<itemTemplate>
<%
// Need to ensure Container exists in current context

I have a databound dropdown list (ASP.net). I want the page to load with a certain item as the selected item.
I am not adding a blank first row (thats not what i need)I find that I can get this to work with "AppendDataBoundItems" to true, but the side-effect is that I have all the items listed twice.
I know the question has already been posted here but we didn't get to an real solution.I have bound my ListView to an SqlDataSource and I want to write some text in a control present in the view created in the LayoutTemplate depending on some properties of the rows returned.Obviously, I'm using the ItemDataBound event to feed my items but this is not the point.
The spontaneous solution was to bind the ListView.DataBound event and access the raw datasource (a DataTable?) and do the required calculations.I inspected the Items property and, despite it was not empty, the related DataItem property was null.The only work-around I can come to is to execute the calculations in the ItemDataBound event and accumulate the result in some private fields. But it's really ugly to see and makes harder to get some of the required values.
[I'm working in Microsoft Visual Studio 2005 with C# Language]There is a series of forms that I'm prepopulating with data from a SQL database. Every page that I've created in this way I've coded the needed information required into the method:protected void Page_Load(object sender, EventArgs e)and doesn't fire if it's a postback event.This latest form has a CheckBoxGroup that is databound and populates based on a table in the database. However, the form only prepopulates after a postback. Prior, the Item.Count says 1 when I know that there are 14 items. Again, it reads fine after the postback. I assume that this is because the CheckBoxGroup populates after the Page_Load function.Is there a way that I can make something like this fire during the Page_Load and not during the postback?
View 2 RepliesI have the following line to display a piece of data and I want to know how I can format the output.
Text='<%# Eval("DOH") %>'
The data list displays the correct data, but I want to format it. The output I want is just a small date format instead of date and time. I have tried every combination of a format function I can think of, but can't seem to make it work. Am I stuck with the raw format provided by the database? I wouldn't think so, but maybe that is the case.
expected output should be 02/15/2011 instead of 02/15/2011 09:45:

View 2 RepliesI have a dropdownlist as a template item in a gridview - it populates fine and with the right values. I have an SelectedIndexChanged on the dropdownlist, and has set it for postback. In the SelectedIndexChanged event, I would like to know where the control that fired this event is, - which row in the gridview is it in? How do I get this info? If the row was selected it would be easy, but the only thing that has happened in that row is that the dropdown has changed value and consequently the SelectedIndexChanged event has been fired - is that enough to know which row the event has been fired from?

I have one gridivew, which is showing 20 records. And also, in item template of Gridview, I used one dropdownlist. It means there are 20 dropdownlist with all the 20 rows. That dropdownlist is already binded, means showing the records/items - 8 items. No issue with this.
Now, what I want is, when ever, I select any item from the drodownlist against each row in that gridview and click on the button "Save", it will save the id of all row with all the values of dropdownlist.
The Detailsview has a template containing a textbox for one of it's fields.When an item is selected in the Gridview, I want to set a property of the textbox. How do I do that? I've tried Findcontrol for the item during Prerender of the detailsview. I've also tried many other things. Below is a portion of my aspx code followed by my VB code.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataKeyNames="LU_DutyStations_ID" DataSourceID="SqlDataSource1">
