Forms Data Controls :: Utilize About 30 Different Database Values From Within A Repeater ItemDataBound Event

Jan 18, 2010

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.

Forms Data Controls :: How To Access Attributeid Values In Repeater Control's ItemDataBound Event Handler

Jan 15, 2011

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.

Raise ItemDataBound Event From Repeater Within User Control To Page?

May 20, 2010

I have a user control that contains a repeater. We have added some paging and sorting into the user control and it all works well.

What I need now is a nice way to catch the OnItemDataBound event of the inner repeater and then bubble it up to be accessible directly from the user control from within the page.

We have tried catching it and then declaring it in the user control but it just won't work.

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();?

Forms Data Controls :: Typecast A Drop Down List In ItemDataBound Event?

Jun 30, 2010

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?

Forms Data Controls :: Using ItemDataBound Event - Assigning Data?

Dec 13, 2010

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.

Repeater Itemdatabound Event Value Type And Reference Type?

Mar 29, 2010

Im trying to bind a list with datetime objects to my repeater.

if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)
{
DateTime actualDate = e.Item.DataItem as DateTime;
}

When I want access the itemdatabound event on the repeater Then I get an errormessage which says that DateTime is a valuetype and not a reference type.My solution is that a wrap the datetime in a custom object (reference type) and pass that to the repeater datasource instead of the datetime. But Im wondering if there are other solutions where the repeater takes valuetypes (DateTime objects).

Web Forms :: Creating Dynamic Controls In ListView's ItemDataBound Event?

Jan 12, 2011

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?
