Web Forms :: Manipulate Datafields In Listview Template?
Apr 22, 2010
I have a listview I'm using to show some data. My question is, how do I manipulate that data being presented. For example, I have a label in my listview template that looks like this:
<asp:Label
ID="lblTerminalA"
runat="server"
Text='<%= Eval("MOT")%>'
/>
The listview's datasource is a datatable. lets say that data when presented looks like "SOME COMPANY NAME T4220" I only want to write to the screen "T4220" and trim off the stuff before it. How do I go about doing this?

In my edit template I want a dropdownlist containing a list of possible customers. The list is populated from a database table containing existing customers. If the main record has customer "XYZ", then I want that customer to be the default in the dropdown. I'm using VS 2008 and C# My markup for the dropdownlist is currently:
[Code]....
The dropdownlist is populated but the problem is it shows the first customer in the list. I don't want the user to have to rechoose customer if that is not what they are changing.

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 have a GridBoundColumn that I would like to be bound to 2 fields so that I can display the two fields in one column. I would like to do something like the following:
<GridBoundColumn DataField1="LastName" DataField2="FirstName" DataFormatString="{0},{1}">
Is this possible? If so how can it be accomplished?
This is used in a Telerik RadGrid if that makes any difference.

While running ItemDetabound upon load of a listivew, I am trying to access the text in a label of the LayoutTemplate of a different Listview. It works fine if I try access the same labels under the same names if they are in the same listview, but not if they are in a different one. It was working for a while, can't figure out what I changed, but now says that object doesn't exist.

I am trying to do this with many issues of data binding doubling the amount and not setting selectedValue on dropdownlist. I have read some posts and they help but I am missing a crucial piece. My problem is that my dropdownlist is doubling the amount of records for the dropdownlist. Instead of "YES;NO;SELECT A VALUE", I am getting "YES;NO;SELECT A VALUE;YES;NO;YES;NO". My database is correct with the UPDATE part but the rebind after update is failing horribly.

Using a listview control for the first time... I need a button for each item, and of course I need to handle the click event for the buttons... upon clicking a particular button I of course need to know which item the button is associated with so the appropriate action can be taken...
In VS, I can't select the button and see my list of available events in the properties window like is normally done for controls outside of templates like this... what do I need to do?

From what I can tell the listview doesn't have a header template. I'd like to be able to list and line up the column names with the data on my list view, but there doesn't seem to be a straightforward way to do this. If I put it in a table in the item template, it lines up like I want it, but it of course repeats which is what I don't want.

A have a ListView that is rendered with multiple items. Now I want to toggle some HTML attributes with JQuery. Therefore it would be best to have access to these elements via an unique ID.
But trying to create a "dynamic" and therefore unique ID by
<tr runat="server" ID='<%# this.GetUniqueID() %>'>
</tr>
results in an error that tells me that the ID needs to be simple and cannot be set by a call to a method.
I know that I can dynamically create controls in the code-behind and set the ID there. But in this case, I'd rather like to let the content be rendered by the ListView itself.
That brings me to the conclusion that the idea of setting a dynically ID in the Template is totally wrong. How can I achieve the desired behaviour?
Edit: Ok I just found out, that I can set the ID with a BindingExpression, like
ID='<%# Eval("MyColumnWithUniqueID") %>'
Still, is there another, or even better solution to this?

I have a list view with a label that shows "Step #x", another label with the instructions, and then 2 linkbuttons for editing or deleting. At the footer of the ListView is another button "Add New Step" which opens up an empty TextBox and two buttons to save and cancel. I would also like it to increment the label, but I can seem to find the control in the code behind to change it's text. How do I do this?
Here's the asp markup:
<asp:ListView ID="lvSteps" runat="server" DataSourceID="ldsProcessStep" DataKeyNames="ID" InsertItemPosition="None">
<LayoutTemplate>
<div><asp:PlaceHolder ID="itemPlaceholder" runat="server" /></div>

In my listview object insert/edit template, I have two dropdownlists (category, subcategory). When a user selects a category (autopostback), I would like the subcategory dropdown to filter to only the those that match the categoryID from the category ddl. This seems to be complicated by the fact that it is in a listview object. I'm currently using a queryextender on the subcategory datasource, but I'm not sure how to apply the selectedvalue of the category to the queryextender. The subcategory just shows all items and is not filtered. How do you accomplish this?

Background: I'm populating lots of asp.net c# GridViews and ListViews from a database and subsequently users may export them to Excel. I want export as native Excel (not html). I can't use office automation, and I'm using JET which works fine. I have no control over users' machines. Question: When doing the export, you have to tell Jet what type each field is, in my case "text" (varchar) or "numeric" (double). The difference is that if you export a numeric column, the users can sum the data in Excel, where as strings are exported with a leading apostrophe and so are not much use in arithmetic.
Currently I parse the first data row of the Grid/ListView, check if each value is numeric or text, and assign a type to the column accordingly. That works, except for when I have something in the first column which looks numeric but in fact is a text string. I don't want to parse every row in order to be sure I have the correct data type as some of these exports are quite large. When I load the Grid/ListView from the database, the database certainly knows what type each field is. So my question is... how do I extract the type of the database item behind a a Grid/ListView item? I could explicitly code it as an attribute on the item, but that's duplicating information I already have, if only I can get to it. I know that where I have a DataTable then I can get the underlying type from that, but mostly I don't have tables handy, just the Grid/ListView. Note that Jet will throw if you try to insert an empty string into a nullable numeric column. The way to do this is to omit that column name from the insert statement, or output a zero.
