Forms Data Controls :: Format Generic List Bound To Gridview
Aug 21, 2010
I have a generic list of a custom type. The custom type has a string and double.I'm binding the list to a gridview and it outputs everything fine.I'm trying to format the double column into a currency format. It is in a template field as I'm calculating a running total. I pass the value to a function that returns a double and adds the current value to a running total which I will show in the footer.
The format is not changing to currency as expected when using String.Format("{0:c}", GetTotal(Convert.ToDouble(Eval("Amount"))))

I'm hitting a wall trying to format a boundfield of a gridview. I've tried suggestion about setting the htmlencode to false, but that didn't make a difference.The column I am trying to format is:<asp:BoundField DataField="FromDate" HeaderText="Start Date" DataFormatString="{0:MM/dd/yyyy}" HtmlEncode="False" />

I have a bound column.
<asp:BoundField DataField="WorkPreference" HeaderText="WorkPreference"
HeaderStyle-HorizontalAlign="Left">
<HeaderStyle HorizontalAlign="Left" />
</asp:BoundField>
dr["WorkPreference"] = sa.WorkPreference ( This is how I bind the data to a DataRow)
The example of the data which gets bound to this column is like the following:
Communications and Marketing Officers; Environmental Assessors; Geologists and Geosciences; Geospatial/Spatial Information Officers;
What I want is that the data should be presented to the user like the following:
Communications and Marketing Officers
Environmental Assessors
Geologists and Geosciences
Geospatial/Spatial Information Officers
In short: I basicaly want to put a break where there is a colon and then bind the data to the gridview. It looks like simple but if you can let me know.

I have a databound FormView with a dropdown list of categories. All works as expected, but I want to provide the facility for the user to add a new category to the list and I can't find an elegant way to do it. My current approach is to have a simple modal popup (Ajax toolkit) with a FormView (bound to the Categories table). That successfully inserts the new row, but it doesn't show in the dropdown so it can't be selected. I can force a refresh by calling formview.DataBind() in a suitable event handler, but that of course moves the formview off the selected record and loses any changes the user may have made.
Is there a convenient way (perhaps using AJAX, avoiding a postback entirely) to update the Categories table and refresh the dropdown without moving off of the current FormView's record? I feel sure this
must be a frequent and basic requirement, but I've not found any mention of how to implement it.

How can I bind a datalist control with a list of objects. I have a list of objects that contain a name, desc, and url for menu commands that I am trying to show in a DataList. I am getting the list from a WCF service so I have a list called something like menuList which consists of a List<MenuCommands>. I then do a menuDataList.DataSource = menuList and then a menuList.DataBind but nothing is happening. What am I missing here? I need to use a DataList because I need the commands to be selectable.

I have a ListView which is filled by generic list of type MyClass. I can easily bind data from this list into ListView. But I have problems with reading data in opposite direction. This is my class:
[Code]....
I have also generic list of type MyClass:
[Code]....
Finally I bind data to ListView this way:
[Code]....
My ListView template:
[Code]....
How can I read data from ListView into my List list?
The operation of reading ListView data into List generic list should begin after clicking the button "GetData".
I saw the following advice:
[Code]....
but it does not work - the DataItem property of each Item of ListView has null value. The point is that I have generic list with data. I am binding this data into ListView which can be edited by user. After that after click Save or GetData data from ListView is read into generic list of MyClass type.

If the gridview binds to empty dataset, I need to still show a gridview so that users can ADD more using the textfields in the bottom of the footer template. Since the gridview is empty it won't bind not allowing rendering of the <footer template> I guess I should create a empty dataset if the gridview is empty. How do I check for this and can this be done in GridviewRowEventArgs
