sort gridview with ObjectContainerDataSource

Posted By:      Posted Date: April 10, 2011    Points: 0   Category :ASP.Net


I have a simple DTO object:?

Public Class TransactionDTO
    Public Property IDTransaction As Integer
    Public Property Subject As String
    Public Property StartDate As DateTime 
    Public Property EndDate As Nullable(of DateTime)
End Class


I bind this dto to a gridview with a ?ObjectContainerDataSource and try to sort to EndDate but I always receive the following error:??

Property 'EndDate' does not implement IComparable


Is there a workaround for this?

gridview sort on changed cell text


I have a gridview that is being databound by an SQLdatasource and on  RowDataBound i am doing a calculation and then setting


e.Row.cells(17).text = Result


However, when I go to sort it on the website it sorts it based off the previous values.


Cell(17) from the datasource reads in all 1's. The numbers I change it to range from 0 to 15. So when I click sort nothing changes because it sees it as all 1's.

How can i make the gridivew sort off the changed text values?

Why when I click on title header to sort a GridView, some data disappear?


 Hi there

When I click on my GridView header "End Time" all the rows which contain the string "N/A" disappear.
Here is my code:

protected void GridView2_Sorting(object sender, GridViewSortEventArgs e)
FillDataGridView_JobHistory(ViewState["DateBegin"].ToString(), ViewState["DateEnd"].ToString());

Note: GetSortDirection returns "endTime ASC" or "endTime DESC" and save in ViewState:

ViewState["SortDirection_JobHistory"] = sortDirection;
ViewState["SortExpression_JobHistory"] = column;

Then I fill the DataAdapter and use the ViewState info to sort it:

protected void FillDataGridView_JobHistory(string dateBegin, string dateEnd)
string query = "dbo.GetJobHistory";
DataTable dt = new DataTable();
SqlConnection myConnection = new SqlConnection(WebConfigurationManager.ConnectionStrings["ConnString"].ConnectionString);

SqlCommand cmd = new SqlCommand(query, myConnection);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(new SqlParameter("@dateBegin", SqlDbType.DateTime));
cmd.Parameters.Add(new SqlParameter("@dateEnd", SqlDbTyp

Sort not working in gridview after changing headings


Hi all,

I'm developing a bilingual web site, and therefore, I'm changing the text of the headings and the select buttons of my gridviews. I just discovered that if I set some code like below in the rowdatabound event of the gridview, the "linkbuttonish" headings get replaced by unclickable text. Thus, sorting the gridview is suddenly not working. What should I write instead?

If Session("lang") = "en" Then
            If e.Row.RowType = DataControlRowType.Header Then
                e.Row.Cells("name").Text = "Given name"
             End If
        End If

I guess that I should write something else than "e.Row.Cells("name").Text" to still have the click-behaviour, but I don't know what.

The same question arises for the select linkbutton in a cell of the gridview's datarows.

Thanks a lot!


Inplace Edit in GridView

GridView Confirmation Box Using JQuery BlockUI in asp.net

Textbox Editable GridView in ASP.NET

This article describes how I made a fully editable gridview in C# using ASP.NET 2. The idea is that the GridView looks and works like an Excel spreadsheet. You see all the cells in the table, and you can edit any of the cells you like, and they are automatically updated (i.e. saved to the database). This is very often how people expect data tables to work in web pages, and I've often seen people clicking in vain on un-editable gridview cells, somehow expecting to edit them, and not understanding that they need to click an Edit button at the end of the row.

Adding Dynamic Rows in ASP.NET GridView Control with TextBoxes and with Delete functionality

In my previous examples, I have demonstrated on how to add dynamic rows in GridView control with TextBoxes and how to save the values into the database. Now, seems that most of the developers are asking if how to add a delete functionality with it. So in this example, I'm going to show on how to delete a certain row in the dynamic GridView with TextBoxes.
