I tried to generate Button control on the fly repeater's ItemDataBound event.
[Code]....
However, when I am about to capture the gridview's itemcommand event, it seems like the command doesn't work.
how do i fire the itemdatabound event for a repeater control which is nested inside a another repeater control
code is in vb.net
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 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.
how to fetch values of repeater control in the ItemDataBound event i wrote the following asp code
[Code]....
but i get empty value in content and url...
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.
i have a repeater control and on ItemDataBound event i want fetch values in the repeater control and redirect to another page by passing those values as parameter. i have written the following code

I actually need a little help here I'm using LINQ and displaying some data through a Repeater, with everything working fine. The scenario is: for example, user "Daniel" has 2 songs; on my Linqdatasource I'm selecting "songName" (name of the file name to put it on my mediaplayer, to populate the mediaurl) and the "plainName" (the name which the user inserted as the name of the song). So I'm just gathering 2 strings. My .aspx code:
[Code]....
I have a LINQ Table "Vote" (userID, songID, vote -> float)... and I want to rate each song (at the moment there are 2 songs... and the limit will be 3 per user), via the button "rateSong"... I'm not expecting you to give me the code to perform the specific rating, but how will I get to the specific button event? Is it in the Repeater1_ItemCommand?
[Code]....
I've searched for a few posts on this forum, but none of them helped
I have a ListView that is managing a link click event through the OnItemCommand and the list pages the data.
<asp:ListView
runat="server"
ID="lvRequests"
ItemPlaceholderID="litPlaceHolder"
OnItemCommand="lvRequests_ItemCommand"
DataSourceID="odsResults"
OnItemDataBound="lvRequests_ItemDataBound">
<LayoutTemplate>
</LayoutTemplate>
<ItemTemplate>
<tr>
<td>
<asp:Label runat="server" ID="lblSPNMatch" Visible="false" />......................
i have a repeater with a button in the footer template which i want to be able to update any of the items that are added (update quantites/totals/delete the item).
however the 'UpdateOrderDetails' event never fires when the button is clicked.
here is the code within the repeater...
<ItemTemplate>
<tr>
<td>
<asp:CheckBox ID="chkDelete" runat="server" />
<asp:HiddenField ID="hidProduct_Key" runat="server" />
[Code].....
but this procedure is never called when the button is clicked, so wondered what i need to do to get this working
how many times itemDataBound event calls exactly, if my datatable have 2 records it is calling 4 times , first time in item index 0 , second time it is 1 and third time again it contains index 0 and forth time it is 1. so, could anyone please help me how the itemdatabound event actually works,
View 5 RepliesI 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?

View 4 RepliesI 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();?
View 27 RepliesI 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 have a repeater control and in its footer temlate is a button (or 2 in the example) and I want to catch its click event but seem to not be able to.
I tried in the repeater itemcommand event and also I tried defining a subprocedure for the 'occlick' event but neither works..
[code]...
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?
View 4 RepliesI 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 this code
protected void Page_Load(object sender, EventArgs e) {
if (!IsPostBack) {
ArrayList olist = new ArrayList() {"visible", "invisible", "visible", "visible", "visible", "invisible", "visible", "visible", "invisible"};
for (int i = 0; i <= olist.Count-1; i++) {
if (olist[i].ToString() == "visible" ) {
[Code] ....
I want to hide the button if records found "invisible".
The output must be like this:
-----------------------------------------------------------------------------------------------------
Another question is
I want to get the button index value inside the repeater row, when the user click the button the index value display one Label3
void repbtn_Click(object sender, EventArgs e) {
Label3.Text = "The button item index that clicked in the repeater is: "; // + irepeater.Items. ;
}
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).
I have a panel which has a repeater within it. Within the repeater I have a few controls. One of those controls is a Drop Down list which has an OnSelectedIndexChanged event. I can get this to fire without issue but I cannot find my DropDownList control within that repeater within the SelectedIndexChanged event . The repeater has an OnItemDataBound event and I can use the RepeaterItemEventArgs to find the control using e.Item.FindControl("ControlName") without issue but when that event occurs is NOT when I need to find the DropDownList.
What I want to do is have another control's Visible property be set to "true" when the value of the DropDownList meets a certain value. As far as I know I can only do this during the SelectedIndexChanged event and I can't change the signature of the event by trying to use RepeaterItemEventArgs.
I'm trying to get this accordian to get my data to display with a gridview in it, it renders fine, my datatable is being filled and it seem to bind but then there it no data and it skips my itemdatabound event in my code behind... Nothing loads!
if there is a bug with the databound event in vb.net or for this ajax control?

I have a user control (this has a label to display question and a radio button list to show options).
I am using this user control inside a repeater to display all the questions with their options.
In my repeater page I am not able to capture SelectedValue of radio button list.

I have a check box in the grid.IF IsChecked has a value checkbox should be checked else not.Should i check the check box in the ItemDataBound event or will it get checked automatically.
