I have a question about C Sharp ASP.NET:Is there a difference (in code speed, resources) between:public static variable declared in public static class MyGlobals in a 'Code File' template;and the variable declared in a normal 'Class File' template;I use this variable in 2 different Class Files and also in _Default Page codebehind cs file.In fact in my case I need about 20 global variables of type List<string>.

I want to sort the string which is in the format given below15% Test;15% Sear;40% Santhosh;30% Jeeson;
The output that I am expecting is
40% Santhosh;30% Jeeson;15% Sear;15% Test;
I wrote the following code but it does not work .
string str = "15% Test;15% Sear;40% Santhosh;30% Jeeson;";
Console.WriteLine(str);
DataTable dt = new DataTable("SortBenchMark");
DataRow dr;
dt.Columns.Add("Weightings", typeof(int));
dt.Columns.Add("BenchMark", typeof(string));
string weightings = string.Empty;
string BenchMarkName = string.Empty;
foreach (object o in str.Split(';'))
{
if(o.ToString().Length > 0)
{
dr = dt.NewRow();
dr["Weightings"] = Convert.ToInt32((o.ToString().Split('%'))[0].ToString().Trim());
dr["BenchMark"] = (o.ToString().Split('%'))[1].ToString().Trim();
dt.Rows.Add(dr);
}
}
dt.AcceptChanges();
DataView dataview = new DataView(dt);
dataview.Sort = "Weightings DESC,BenchMark Asc";
string final = string.Empty;
foreach (DataRow drow in dataview.Table.Rows)

My web application works if I don't compile it, when I compile, it gives me this nasty error and I am clueless to what I did wrong?
Here is the error: No where in my line 113 has any Eval nor my entire page has any Eval, I used Bind so what is going on? the strange thing is if I leave the page as is with out Publish web site option the same page works perfectly fine.

What is the difference between dataview and datarowview?
What is the use of datarowview?
HOW TO specify which columns are in a DataView from a DataTable. I want to create a DataView, that only has the columns from a DataTable that I choose, and in the order I want.
Example:
// DataTable_MyTable ~~ Column #0 is for ID. I do not want my view to get this column.
// DataTable_MyTable ~~ Column #1 is for TYPE. I want this column to come in 2nd place in my view.
// DataTable_MyTable ~~ Column #2 is for NAME. I want this column to com in 1st place in my view.
DataView DataView_MyView = new DataView(DataTable_MyTable ~~ some how only get the columns I want, and in the order I want ~~);
// DataView_MyView now has only 2 columns.
// DataView_MyView ~~ Column #0 is NAME.
// DataView_MyView ~~ Column #1 is TYPE.
I have a datatable which contains the summery row as well. I just assign the datasource property of a gridview and call databind method to fill and display the records.
Now, when I applied sorting through dataview to the gridview, the sorting happens along with the summery row, which is a normal behavior. As a result the "Total" - column took place inside the data some times. I want to prevent this.
The best way out for that can be done by creating the summery row at grid view row databound. But unfortunately I could not change the datatable as per this requirement.
Can the dataview sorting exclude the last row of the datatable through any process?..
I know how to do this in a datatable but I would just like to learn how to do it in a dataview.
I have a dataview which is used to populate a gridview. It has the following column
userid Location
123 New York
124 Chicago
125 London
Now, I would like to know how to determine the 124 row and highlight it to a blue in a dataview used to populate a gridview. kindly note, i can do this in a datatable but not a dataview. I would like to learn how to do it in a dataview.

The Dataview control is not appearing when the page is loaded. Has anyone any ideas ?
I have tried the online converters, and none of them that I have tried will accurately convert this. It still tries to add a .Item property to the dataview and that does not exist in c#. I know this is simple...
dv.Item(e.Item.ItemIndex).Row.Item(1)
I'm trying to export a filtered dataview to excel. The code to export works just fine but it exports all the records, not just the ones I filtered on. For example, I have three dropdowns and the dataview seems to work just fine filtering on the dropdown parameters because it shows up correctly in my datagrid on my screen.
This line of code is where I am confused.

Im trying to populate my formview from a dataview in the codebehind and the order in which things are happening is causing it to fail.my formview itemtemplate is setup with some eval("fields") which is initially not populated (nothing bound to it) and the page loads ok. i think click on my graph which generates a query and populates a dataview.i then assign that dataview to the formview and run the bind.what happens when i actually run the app is that it says no data is bound to it.i set the debugged to stop at the point where my DV is assigned to my FV and the FV shows a data item count of 1 (as expected) if i keep stepping it puts me in to the eval statements on the aspx page says the data isnt bound.
the error i get is
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.

I have a user control which I am passing a DataRow to, Within this cotrol I have many ( textboxes ) which I would like to perform two-way binding to my DataRow. doing this will save a lot of work for me. I have searched high and low and can't seem to make this two-way databinding work.
View 9 RepliesI have this peace of code that collects data from checkbox list and concatenates it into a string. It worked fine on lots of pages then i added it to a page that uses a formview update template, and now the name of the checkbox (CategoryList) list comes up as not declared in the script header. Do i need to change the protected sub line to show items in the form view?

I am using a dataview to read a certain record from a database and then adding these values to different elements on a form (label, textbox) ..
One of the fields is a date/time and i only want to display the date without the time..
code:
{on page load}
Dim dv As System.Data.DataView = CType(DEDS.Select(DataSourceSelectArguments.Empty), System.Data.DataView)
lbl_startdate.Text = dv.Table.Rows(0).Item("'<%# Eval("evt_startdate","{0:d}")%>'").ToString()
' DEDS is my SqlDatasource ..
'evt_startdate is the date field coming from the DEDS datasource
.. It's not working .. I'm not sure how i should alter the date format ..
I have a dataview running a stored procedure that's populating a textbox. I then want to edit (or not) that text and insert it using another query. However, whenever I populate the text box, it will always insert the original text. If i don't populate it, it will insert whatever text I input.

how to sort a datatable (dataview) so that the second column is ascending but nulls are last.
I'm trying to do the following Date1 ASC, DATE2 ASC (but if DATE2 is null it is last in this Date1 group)
Note: Date1 can never be null so a Date2 that is null should still be grouped in with its Date1.
I have developed my application using Visual Web Developer 2008 express with Visual Basic code.
If I am working with 2 textboxs on a form, and I set the "Autopostback" to "true" for the first texbox then on the "changed" event, I can just add code to set the visibility to "true or "false" for the second textbox - it works fine. However, I do not seem to be able to figure out how to do the same thing when I am using a Dataview.
I have a table called "Customer" that contains 4 fields "CustomerName", "BasePrice", "LevelOfActivity", and "Discount".
My user enters information into this table using a Dataview form that displays the 4 fields.
When the user enters the value "L" in the field "LevelOfActivity", I would like to then set the visibility of the field "Discount" to "false" - (I want to hide the field as this customer should not get a discount). If the user enters the value "H" in the field "LevelOfActivity", I would like to then set the visibility of the field "Discount" to "true" - (I want to show the field so the user can enter the "Discount").
