I've a listview with object datasource as source control.
I'm using listview events for update and delete.
on update event i.e in itemcommand==update , I'm rising a javascript event on validation.
So when this validation raises I want the listview to be edit mode on the same row.
For this under Listview updating event I used the following:
[Code]....
but I'm facing the below error:
Updating is not supported by ObjectDataSource 'odsCategory' unless the UpdateMethod is specified.
I have tried in many way but the error message for custom validator is not shown in validation summary but it(ValidationSummary) shows error message for every other type of validator.

I want to design custom control with ListView and datapager that take Query - As Input PagingSize - As Input
This custom control is suppose to be use in different aspx reporting pages
when record is deleted in gridview when we press backspace button the record is back, when click that record the error message no records at rows 0 is found
View 2 RepliesI want to access the data that was databound to my list view when handling list view events such as:
protected void List_ItemDataBound(object sender, ListViewItemEventArgs e)
or
protected void List_ItemCommand(object sender, ListViewCommandEventArgs e)
Inside the events, I can not access the data via somthing like Eval("ID")
Currently we are using a very hacky solution:
string id = e.Item.FindControl("lblID").Text;
Where lblID is a hidden control that is populated with data in the aspx file using:
<asp:Label ID="lblID" runat="server" Text='<%# Eval("ID") %>' />
My eyes bleed when I look at this, Is there a better way?
In ASP.NET 4.0 webforms, I'm trying to export a paged ListView control to an Excel file by un-paging the ListView's (trucks) datasource:
dsTrucks.EnablePaging = false;
For a non-paged ListView control, I can get it to work.
Here's the attempt to "un-page" and then export the ListView control:
[Code]....
There's no error but the output in the Excel file is still just one page of the ListView control instead of all rows.
I am using Asp.net 3.5, C#, Visual Studio 2008. Ok, so I admit I am being really lazy here, but I know there's got to be a way to do this.
I have 2 identical listviews - listview1 and listview2. There is a checkbox in column 1 of both listviews, and a button on the page.
I would like to copy the rows that are checked in listview1 to listview2 when the button is pressed.
I know how to do this by looping thru listview1, but how can I do it in one step using an ObjectDataSource?
I have a function which returns dataset after execution of sql statements
If the dataset retruns rows than he data shld be dislayed in reporting services
Else display no rows avaliable
But currently even if there are no rows as per the given condition, the earlier data gets displayed
I was wondering if someone could point me in the right direction:
How do I generate a custom error page with the error message and get it to mail me that error message?
Is there a good tutorial out there that someone could point me 2.
I have 2 tables. Table1 and Table2 are related with Column Uid.
Table1 Table2
UId Name
Id Car Uid
10 Stalin 1 Audi 10
20 Antony 2 BMW 10
Here Stalin has 2 cars, one is Audi and other is BMW. I have to display output in a webpage like below.
Name Car__
| Stalin | Audi |
| | BMW |
In which control can we get the output like above. No problem whether it in Listview or Gridview controls.
I am trying to have a listview which will work like a table with paging. My problem is I need to be able to add more than 1 row at a time. ie I want to click "add new row" multiple times on the same page without the page changing and without the rows I'm adding going away.
Basically I need the user to still see the already inserted rows as well as the rows they are planning to insert on the same page. This would mean the page size is temporarily larger than it should be. The new rows would be added to the end of my data source when the user goes to another page or clicks a separate save button. However the user can add as many new rows while on a page as they wish and the page would simply grow.
When render a databound ListView I want to dynamically set the background colour of each row depending on the results, in my case Red, Orange and Green.
protected void ListView1_ItemCreated(object sender, ListViewItemEventArgs e)
{
DataRow myRow;
[code]...
I tried to use ListView with following code to display 2 columns for name and address:
<asp:ListView ID="ListView1" runat="server">
<LayoutTemplate>
<ol>
<asp:PlaceHolder ID="itemPlaceholder" runat="server" />
</ol>
</LayoutTemplate>
<ItemTemplate>
<li>
<%# Eval("PersonName") %>
<%# Eval("PersonAddress")%>
</li>
</ItemTemplate>
</asp:ListView>
The problem is the address is not aligned depends on the person's name length.
I want to have 2 columns aligned and with horizontal and vertical grid lines. Can I do that?
I have a save boutton outside the listview and i want to save all the value records of listview at once or row by row in databace (sql server).
View 1 Replies in dragging multiple rows using the jquery plugin used in this link.
http://www.pedrera.com/blog/index.php/aspnet-listview-drag-and-drop-reordering-using-jquery/.
I implemented the single row drag and drop and its working perfectly but I am new to jquery so finding difficult to figure out.
I've searched for this several times but have never been able to find the answer with my search terms. Say you have a listview and a datapager set to 10 rows, but you only have 4 data items in the database at the time the query is run. Is there a way to force it to show a 10 row table (4 with data and 6 without)?
Everytime I search on this, I just find information on setting the number of rows for the datapager, which will not show empty rows if the data isn't there. Probably an easy solution, but the heck I can find it.
I have a listview, that shows 8 rows until creating another page to navigate to to see the rest. I can't figure out where the limitation of the number of rows is coming from
View 7 RepliesTo Start with, I am new to .NET. So I am not refer to the right word, but I'll write up whatever I can.
Basically I have 3 input fields and then a search field.
When I hit the Search field, based on the 3 inputs, it needs to get the DataSet and fill it in the ListView.
I believe it is doing it. But when I added the DataPager, it lists only the first 10 rows, even if hit NEXT
Here is the code ib the .aspx page to populate the ListView
asp:ListView
ID="FISIItemsList"
ItemPlaceHolderID="ListFISIItems"
Since the NEXT button is not working, I thought of Adding the DataSet to a Properties. The and getting it back.So I did something like
public
DataSet
dsFISIItems[code]....
Even this doesn't work.
In simple terms, > After the 3 input fields are filled out, when a "Search" Button is hit, it should go and pick the list of items based on that criteria
> The result dataset needs to be binded to the ListView
> Next, the DataPager control should be paging. But it is not paging.
When I hit the next, it lists only the first 10 items repeatedly.
I am able to show an alert when the list view is edited in parent window like this...
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "MyScript", "<script language='javascript'>alert('Hello');</script>");
but not able to show an alert when this listview is edited in Pop-up window.it shows "Object reference not set to an instance of an object." Error .any idea how to show an alert here!!
It seems that VS always displays more than 20 rows of ListView in its designer. If a page has quite a few of ListViews, it is a bit hassle to move around. Is there any way to reduce the number of displayed rows?

View 1 RepliesI want to name the headers of the ListView control acording to values of the first rows of a table in the database. This I want to do because the number of columns varies for each cutstomer and also the name of the column.
View 10 RepliesI have a Results.aspx page that displays the resulting records queried using a SqlDataSource object via a ListView. I want to add a "View" button that will appear next to each record, and when clicked will take me to a separate page that will display details about that record. How do I accomplish this?
Edit
I have tried what you said, citronas and here's what I've come up with:
[Code]....
Unfortunately nothing actually happens...am I missing something?
Edit -- Fixed
I was missing something! I had CommandName equal to my method name instead of OnCommand. I took out CommandName, kept the argument bit and replaced CommandName with OnCommand. Everything works now, but what would I ever need CommandName for?
