Forms Data Controls :: Force A Listview ItemDataBound Event To Fire?
Apr 20, 2010
I am populating an asp.net listview control from my page_load event. Unfortunately, due to my projects requirements, I have to use a third party control within my listviews ItemTemplate that needs to have database values written to its attributes before my listview control is bound, if this is not the case my control flags a null reference exception error. From some investigation into the listview control, it seems that the only way to do this is through my listviews ItemDataBound event as my thrid party control will hold different value depending on each row.was wondering if it's at all possible to force my listviews ItemDataBound event to fire before I call mylistview.databind();?

I stumbled into a problem which is that FindControl will only return a control in the ListView after the listview has been databound. Here is the code which is not working, and I'm getting the "Object reference not set to an instance of an object error" when I try to add the attribute to the control:
[Code]....
Any ideas on how I can elegantly fix this?

using a listView control... I'm trying to use the ItemDataBound event to map a field's native value to a more 'friendly' name... so far I have the code to access the underlying data so the decision can be made for the actual mapping, but I don't know how to actually change the data displayed?

I'm presenting a list of products within a ListView. Each product can have associated "Options" (Size, Colour etc), but may have none. For each product that gets added, I need to render a dropdownlist for each of its options. E.g. A "Colour" dropdown might have "Black", "White", "Red" etc. I need to generate these controls dynamically, as they are defined by the data itself.
So far, so good. The dropdowns are rendered, and everything "looks" good. The trouble is, I can't work out how to actually get it to work. .Net is complaining about "EnableEventValidation", and ViewState won't work as I've added the controls late in the page's life cycle. As these controls are dynamic, I don't know how to pick up the selected values, and persist them on a post back! When the user clicks on the "Add to basket" option for the product, I need to determine which options the user has selected, and add them to the basket.
Am I missing something here? Is there an easier way of achieving this? I kind-of feel like I'm in a "chicken and egg" situation here. I can't create the controls until the data is loaded (in the ItemDataBound event), but that too late for ViewState. Is there a generally accepted best approach for achieving this sort of thing in ASP/Net?

I'm using VS2008. When a dataset is bound to the DataSource of a ListView, SelectedIndexChanged event does not fire. If I used DataSourceID instead, it has no problem. But SelectedIndexChanging event fires for both.
why and how I can get SelectedIndexChanged event fired when DataSource is used?

Please review the following specific error details and modify your source code appropriately.Compiler Error Message: CS0030: Cannot convert type 'System.Web.UI.WebControls.ListViewItemType' to 'System.Data.DataRowView'

{
if (e.Item.ItemType == ListViewItemType.DataItem)
{
CheckBox chk = (CheckBox)e.Item.FindControl("chkFocusArea");

I previously had a datalist bound to an objectDataSource. Within the ItemDataBound event, i could quite happily access the current bound row as follows:
[Code]....
where ASPNETDB was the database and tblJobs the tableadapter. I could then reference the tblJobs items as job.JobId and job.StartDate etc. Upon chainging the datalist to a listview, I can't seem to find any way of accessing the same data. I've tried ListViewItem and ListViewDataItem, is this the right method or am i missing something?

I am using the ItemDataBound event of a ListView to attach data for the different kind of templates I am using. Well, actually, want to use - I have not yet figured out how to know which template is coming in in the ItemDataBound event. I want to figure out if it is the edititemtemplate, insertitemplate, itemtemplate, etc. All these templates have different controls (edit and insert are the same though) and I need to set the controls contained in them.

I am using a listview to which I want to bind the MembershipUserCollection which you get from GetAllUsers(). I don't want to use reflection, I want to assign it in the ItemDataBound event of my listview. I've done this before, but with datatables. The code will be something like DataRow dr = (e.item.DataItem as DataRowView).Row. You can then access specific columns with
dr["ColumnNamehere"].ToString().
But how do you do this with MembershipUserCollection?

I've created a UserControl that is dynamically placed onto my page during the Init event. It populates and works great, but I'm left scratching my head at how to retrieve data from it during a postback.
It's effectively a multipick combobox that is manipulated entirely using clientside JavaScript (I'm using jQuery heavily). Inside the control container element, I render an empty DIV element that contains all of the selected items. As the user selects items, I generate DIVs within that container DIV that includes some markup. Of interest to me on the server side are the contents of a couple of INPUT fields.
After selecting an item, the rendered HTML looks something like:
[code]....
I may be completely off track and this may actually be impossible (or a stupid idea). The only alternative I can think of is to emit actual ASP.NET controls and hook the built-in event handlers.

I wrote the following code in ItemDataBound Event of the DataList
[Code]....
I have got two questions:
1) If I have already given the data type to d as DropDownList, why do we need to typecast it again to e.Item.FindControl("dd1"). Is it because it will typecast this to the data type of the selected item in Drop Down list?
2) Why do we need to write this in Item Data Bound Event of the DataList?

I need to utilize about 30 different database values from within a repeater ItemDataBound Event and I am wondering if there is a better way to do it. I am currently exposing them by doing something like this 30 times:
[Code]....
Rather than making 30 declarations, is there a way I can make them all available as short variable names? The variable name could be the same as the field name.

I am using a DataList to display records from SQL backend in ASP.net 2.0 Framework 3.5. In the ItemDataBound I am setting up a Hyperlink's URL and enabling/disabling it based on data.
The HTML is as follows:-
[Code]....
and in the vb code:-
[Code]....
This is all working correctly in IE, but in Opera, FireFox and Safari while the Hyperlink works, the control is not disabled if Stk.Docs = 0.

I had a scenario where I needed to massage some data before it got bound to a repeater control, so I first thought to use ItemDataBound event to handle it. I assume this would also apply to gridviews, listviews, etc. The pattern I've seen used to do this is something like:
if (it's the right row type, item, alternating item, etc..)
{ someType row = (someType) e.Item.DataItem
someControlType control = FindControl("controlID")
control.PropertyYouWant = row.FieldYouWant }
In thinking about my task, I'm thinking, ok, intercept the data before it's bound, change it, then let it proceed and do it's normal thing... so the step of finding a particular control and assigning the data to a property of it (like 'text' or 'innerhtml') seemed like an extra step to me? do you always need to explicitly assign the data you want to a control to display? For example, say you have a div tag and the field data needs to be it's content. This already happens when I'm not handling ItemDataBound myself to change the data, is there a way to handle the ItemDataBound event to change the data and have it just display where it would if you were not handling the event? The aspx markup already has an <%# Eval("fieldName") %> within the div tag for placement. I know there is an alternative way to handle the call to massage the data right inside the aspx with a helper function like: <%# HelperFunction(Eval("fieldName")) %>, which is what I have used, but I would like to understand the option of using the ItemDataBound event.

i have simple repeater control on my page:
<asp:Repeater id="Repeater1" runat="server" DataSourceID="SqlDataSource1">
<ItemTemplate>
<asp:TextBox id="txtBox1" runat="server" Text='<%#Eval("attributename") %>'></TextBox>
<ItemTemplate>
</Repeater>
I'm bounding data to repeater control by using SqlDataSource Control
bounded data is something like this:
attributeid attributename
1 color
2 size
How can I get access to attributeid values in Repeater control's ItemDataBound event handler,
I tried to use DataBinder.GetPropertyValue(container,"attribuetid"), but I can't set container, am I doing right, or maybe I should use another approach.

I have a ListView control on a page that I need to support inline editing and inserting. Before I put it inside an update panel, everything was fine. As soon as I put it in an update panel, I seem to lose theOnItemUpdating, OnItemCanceling events. The OnItemEding event still fires, though.I am doing all updating, inserting manually.
