Is there any way to enable alternative ListView (LV2) or any other control in case when ListView (LV1) returns no records from DB? I already have emptydatatamplate designed for this case, but I need to enable a new ListView below in this particular case and I don't know how to achieve this!
View 2 RepliesI have a ListView control that might be empty sometimes. I would like to show a text message like: "No items to Show" when the ListView is empty.
I have read the FAQ of this forum. This issue is not there.
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?
My listview is larger then my page, and I need to be able to add horizontal scroll bars. How do I do that?
View 2 RepliesI'm trying to create a list of items with a listview (ASP.NET VB) and would like to allow a user to use 1 of 2 checkboxes (or radio buttons), to allow them to mark that record as "approve" or "delete", then once they've made all of their selections, they press a button at the bottom to action each of their requests.
So they might select 10 records to delete and 5 to approve, but I want them to run all at the same time, rather than making them edit a field for them all 1 by 1.
I'm also having a bit of trouble identifying a particular record in my codebehind, is the only way to do it through listview1.items then get the index of it, and compare it to the same sql query somehow?

View 1 Repliesusing asp.net 4 and vs 2010 I have a listview that displays data from a database. I have to configure it to display all column data where present, however, not all columns have data, with the result that blank spaces get rendered where this data would normally be displayed.

I have a ListView, I've setup to use an ObjectDataSource, I've created my Layout and Item templates, and I'm able pull and view a list of my data no problem. However I want to add delete capabilities to my
ListView and my reference material tells me to go into the "Configure ListView..." option under the ListView's smart tag, the only problem is I don't have that option, the only three options in my smart tag are "Choose DataSource", "Configure DataSource..." and "Refresh Schema", what am I doing wrong?
I have anested ListView control. I also implemented a jQuery to automatically expand the TextBox control inside of the nested ListView Insert Template. The problem is, when the Textbox expand, the outer ListView control is not; therefore, the Textbox control expands underneath the buttons of the outer listView control. How do I expand the outer ListView control as the nested ListView textbox is automatically expand? One great example is in Facebook where if I add a response comment, it'll automatically push any comments below mine down. If nested Listview control is not the best way to do this, what are my options?
View 8 RepliesDoes anyone have an example for how to create a Dynamically Templated Listview with prefernces page to specify which columns & column order)? Also the listview would also have Edit, delete and insert options if possible. And uses the n-tier approach with Bus Layer and does NOT use LINQ.

Ok, background first:
The form allows a user to create and edit one estimate.
Each estimate can contain multiple Jobs, which are represented in a ListView.
Each Job can contain multiple Parts, which are contained in a ListView that sits in each item of the Jobs ListView.
A user can add and remove as many Jobs as they want.
A user can add and remove as many Parts to/from each Job as they want.
I have no issues adding to each of these, but I do have a problem removing a single part from a single job.
For a reference, here is one Job in the Jobs ListView on the form:
I want to make sure that no matter what a user does, the part of the form they are working on saves what they have. Removing a row from that Parts ListView is no exception. What I want it to do is save the values in each of those textboxes and then delete the necessary row.
Here's what I have in the codebehind:
[Code]....
The EstimateRow variable I create does not get a value from theListView)HFERID.Parent.FindControl("LVEstimateRow") bit of code. There must be another level of nesting that I'm not accessing correctly, because it can't seem to find that nested ListView.
I have a datakey defined on my outermost ListView. When I click on a linkbutton in a row in this listview, the second listview is displayed. This inner listview has several controls and also a linkbutton. When I click this linkbutton, it gets handled by its own event; linkbutton_click. In this event all the data is collected from the innermost listviews' controls, and sends it to the database. The only thing I need within this event is the datakey from the outermost listview.

View 3 RepliesI have a listview control bound to an SqlDataSource. As part of the formatting I want to add a title to the data returned from my database. For instance if the data base returns a phone number I want to add 'Tel.' first. However I do not want to diplay this
title if the datafield is empty. Here is what I have done so far.
<ItemTemplate>
<asp:Label ID="BusinessLabel" runat="server" Text='<%# "Tel. "+Eval("Business") %>' CssClass="TeleStyle" />
Or This:Tel.
<asp:Label ID="BusinessLabel" runat="server" Text='<%# Eval("Business") %>' CssClass="TeleStyle" />
</ItemTemplate>
Business is a phone number. If the data field contains a number I get: Tel. 1234 123456. If the field is empty I get Tel. If Business is null I want nothing dsplayed, how do I do this?

View 6 RepliesI am trying to rewrite an Access Database in to a asp.net front end and i have hit an issue that i can not find a good way round.
in the access version of the software there is a screen the displays all cusotmers and invoice information about these customers, there are currently 15 columns on the screen and we currently have around 25K customers and this will only go up. This is done using a multi column listbox i need to replicate this screen in asp.net but i spent all day on this on as yet not found a good way of do this.
the user will need the ability to select multiple customers at a time and because of the amount of data a scroll bar is a must, this is why the listbox is an ideal tool, apart from the fact the standard one in asp.net does not allow multi columns. grid lines would also be useful. I have look at a few third party multi column multi column list boxes but the only one that i have found that seems to work OBOUT's takes far to long to render 25K rows.
I am trying to populate the ListView using LinqDataSource data source but the issue I am having is.I need to load the listview on Search button click action.
IN the page_load I kept like this:

protected void LinqDS_Selecting(object sender, LinqDataSourceSelectEventArgs e)
{
e.Result = ObjectDS;

This works fine but this happens on page load,i want this binding to happen on button click?is there a way to do this?
I need to create an ASP.net page that has a control on the page that has a five-level TreeView on the left side of the page, and accounting balances on the right side the coincide with each breakdown in the tree. Top level is company, next is group, next is program, etc... and the balances break down accordingly.
I've seen that there are controls out there such as TreeView/ListView combination controls that can do this. Is there any tutorials or out there on how to go about accomplishing this without paying for controls? Could a treeview do this alone by spanning data across the entire length of the columns since every level will have totals on it?
I have a listview and a dropdownlist that is pulling from an SQLTable that I am using to insert data into the ListView, which is associated with the SQLTable. For the life of me I cannot figure out how to get this thing to not allow duplicate entries into the listview.
If I could get at the data that is inside the ListView I think my problem would be solved. At the moment all the code I have is to simply find if I can at least get the data down to something I can compare, from that step I will have no problem writing something functional, at least functional for my needs. I really could use a hand with this:

I don't personally have access to the SQLTable, but I can have somebody make changes if this should/needs to be done from that end, but I would rather do it from this end in VB. I've been digging through the MSDN Libraries
I want to make checkboxes which are already Checked to non editable or readonly to true.
