My GridView control bound to a SqlDataSource does not update
You must take care of below points: The GridView & hence the DataSource never allows changing of the Columns which are specified in DataKeyNames property. Don't try to update a PrimaryKey column. This will not be allowed. Although No error will be shown on clicking update, but if you check the values in Database, changes aren't applied. Make sure your Update command is not trying to set a NEW value for Primary key. as a result, complete Update command will be rejected if you even try to set a Primary Key. i.e. even other Non- Primary key columns will not be changed. So if Id is a primary Key, below update command will be rejected if you specify new value for Id: UpdateCommand="UPDATE Classes SET Id=@Id,Password=@Password,Name=@Name WHERE Id=@Id" So in your case, I guess, Id mus

Formatting a data bound control according to bound data
If you want to play with DataBindings without using CheckedChanged event, here is the solution: Binding bind = new Binding("Checked", bindingSource5, "SchoolContacted"); bind.Format += (s,e) => { e.Value = (int)e.Value == 1; dataRepeater.ItemTemplate.BackColor = ((bool)e.Value) ? Color.Red : Color.White; }; cbSchoolFri.DataBindings.Add(bind); I'm not sure if your dataRepeater.ItemTemplate has a DataBindings property so that we can use dataRepeater.ItemTemplate.DataBindings?

How to bound the header template of the datalist control to a data item?
The HeaderTemplate is not affected by items in your DataSource, so you'll need to bind it to something else. Try creating a public property in your class file: public string Title { get; set; } And bind your HeaderTemplate to it, without Eval: <HeaderTemplate> <asp:LinkButton ID="LinkButton1" runat="server" onclick="LinkButton1_Click" Font-Bold="True" Font-Size="Large" ForeColor="Black" CssClass="heading"> <% =Title %> </asp:LinkButton><br /> </HeaderTemplate>

Directory.GetDirectories in a GridView with Bound Hyperlink
Your GridView's datasource is a List of string (containing the path of your folders). Your bound hyperlink contains an Eval instruction asking to retrieve le FullName property of every item of your DataSource. Your DataSource being a List, it could be translated like that : foreach(string path in files) { HyperLink1.NavigateUrl = path.FullName; } Now hopefully you're beginning to see the problem : the string class doesn't have any FullName property. The solution is to replace the Eval (which is a bad solution anyway, since it does reflection and isn't very efficient) by : <%# Container.DataItem %> Which is a typed variable even that you can cast so you could even write this : <%# (string)Container.DataItem %> EDIT : sorry, I wrote code in C#, I hope you'll under

Spring form control bound to LocalDate defaults to now
I have found a partial way around this problem, but I confess I don't understand why it works. Moving the controls into a JSP tag has helped. This shows no selected date on first page view. If the user enters a date and submits, that is shown on page refresh. However when the form is submitted with the selects empty, the value of the hidden input to which the three selects are linked using a datepicker (which is bound to today's date), is submitted, which is not desirable. It would be ideal if the hidden input were not populated as well, but I think wrapping LocalDate with an object that initialises the date fields as null or empty strings is the only way to achieve that. This is the code which shows the day as not selected on first page load. <spring:bind path="${path}.dayOfMonth"&g

You can use following properties of gridview 'onrowdatabound and DataKeyNames'. In DataKeyNames you can give the name of your class variables or properties where you are reading from database through a datareader. Fire the rowDatabound event of your gridview so that you can check the status protected void gvtransaction_RowDataBound(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e) { int Status = (int)this.gvtransaction.DataKeys[e.Row.RowIndex].Values[0]; if (Status) { . check status values for Accepted, pending and rejected through if else. . . } }

Filter GridView with Javascript
If I understand your question correctly, you are looking for something like this: $(function(){ $('#tabela input').keyup(function(){ var val = $(this).val().toUpperCase(); $('#GridView1> tbody > tr').each(function(index , element){ if($(this).text().toUpperCase().indexOf(val)<0) $(this).hide(); else $(this).show(); }); }); }); Essentially, it iterates through the rows in the grid looking for matches, hiding/showing the rows accordingly. In your markup provided inside the tabela, you can simply have one text input instead of 3. Here's a quick demo.

Is there any way to Edit row of bound fields in gridview with custom edit button?
Everything is possible ;-) But you have to decide how you want the edit to be done. If you're not using the built in functionality to enable editing of the field contents, you need some other kind of editing. One option would be to use a separate details view beneath/besides the table that can be edited. Place the detail view in an update panel to avoid reloading the entire page. You would also need to place the grid view in an update panel to be able to reload it's content smoothly once the edited changes are saved.

It is possible to use DataTables Column Filter Add-on with a Gridview
In order to add anything to the footer, you need to use TemplateField controls rather than BoundField controls. See http://www.dreamincode.net/forums/topic/222381-insert-data-using-gridview-footerrow/ for an example of how to do this. One thing to note though, the HTML generated by the GridView control will use <td> elements in the footer rather than <th> elements as expected by the DataTables documentation.

asp.net gridview user control
Putting the grid view into a user control will lock you off from making <Columns> definitions in your markup where you include your user control, because the grid view definition is not accessible via properties of the user control. From the description of the changes you made that you want to reuse elsewhere, it seems to me that you are better off creating a CSS class that can be applied to all grid views in your application instead of a user control. As for the paging logic, you can have that be in a utility class that all grid views in your application can call to do their paging, if the paging logic is generic enough. The bottom line is you have locked the structure of your grid view by putting it into a user control, because there is no mechanism to alter the structure. You c
