Forms Data Controls :: Display Certain Rows In GridView As Read-Only?

Apr 29, 2010

I have the following fields in an Appointment table:

ID(PK), TeacherID, DayID, TimeslotID, ParentID, StudentID, Remarks & Editable(bit, Default value=1)

I am developing an application to allow parents to book appointments to meet the child's teachers.

It is compulsory for parents to meet child's mentors, hence Appointments to meet class mentors are already pre-booked in the Appointments table.

Parents could still book appointments to meet other subject teachers. I have a column in my gridview to show parents the list of booked appointments. Parents are allowed to change the Appointment timeslot for an appointment they booked and are not allowed to change appointment time for pre-booked appointments.

Under the Remarks colum, it is stated that the following appointment is pre-booked by class mentor.

How do I make only those pre-booked rows read only since all the appointments belonging to a parent is under one GridView.

I found an example, but this is to only make the 1st 3 rows read-only and I don't think this is in VB coding. I'm usingASP.NET VB coding.

Forms Data Controls :: Display Time Difference In GridView?

Aug 3, 2010

I would like to display time difference between previous row in GridView.

I prefer creating new Column in SQL, but I can't come up with getting value from "last row" in SQL statement.

The reason is that I would like to have Total hours.

ID | DateTime | Time Difference
1 | 1/1/2010 1:00:00 am |
2 | 1/1/2010 2:00:00 am | 1:00
3 | 1/1/2010 4:00:00 am | 2:00
Total 3:00

Forms Data Controls :: How To Use The RowDataBound Declaration On A GridView

Aug 11, 2010

I have info from a couple of different tables that I need to be able to double click on a cell in a gridview and navigate to a couple of separate .aspx pages. Yesterday I learned how to use RowDataBound to get the name from a cell on a gridview to use in a delete confirmation dialoge box, and so am pretty sure I should be using this same RowDataBound, but I cant quite figure out where to start.

For example from the gridview below, I need to be able to double click in the "LoginIssue" field and navigate to an "EditLogin.aspx" page and subsequently be able to double click in the "ContractPath" and be able to navigate to a "ContractPath.aspx" page...or popup.

Forms Data Controls :: Use Gridview Rowdatabound In One Cases?

Aug 24, 2010

I have two different functions which are used to generate two different report on one gridview. In otherwords, in my design, I have a calendar event which is used to generate a report on the gridview and I have a dropdownlist which is used to generate a different report on the same gridview, so depending on the control that is clicked on depends on the report being generated. Now I would like a situation where my gridview rowdatabound is only applied to the dropdownlist report not the calendar event report. How can i go about doing so.

Forms Data Controls :: Format A Cell During Rowdatabound In A Gridview?

Aug 13, 2010

I'm attempting to change the format of the 2nd column in a gridview during the rowdatabound event. I pulled sample code from various sources and wrote the following, but it's not working. I tried to do a trace, but the rowdatabound event didn't appear in the trace. Here's some code for the gridview:

[Code]....

Here's what I have in the code behind:

I expected the values in the 2nd template column to get written in italics, but nothing happens. I do have a gridview skin that's getting applied.

Forms Data Controls :: GridView RowDataBound And Edit Mode?

Oct 21, 2010

I have a gridview and a template column:

<asp:TemplateField HeaderText="Active">
<EditItemTemplate>
<asp:CheckBox ID="chkbxActive" runat="server" Checked ='<%# Bind("Active") %>' />
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="lblActive" runat="server" Text='<%# Bind("Active") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>

The item "Active" is a bit from the database And for the RowDataBound:

Const HeavyCheckMark As Char = ChrW(&H2714)
For Each row As GridViewRow In gvProductCodes.Rows
If gvProductCodes.EditIndex = -1 Then
' Selects the text from the Label which is inside the GridView control
Dim lblActive As String = CType(row.FindControl("lblActive"), Label).Text
lblActive = lblActive.Replace("True", HeavyCheckMark)
lblActive = lblActive.Replace("False", "")
'Replaces the text in each Label control
CType(row.FindControl("lblActive"), Label).Text = lblActive
Else
Dim chkbx As CheckBox = CType(row.FindControl("chkbxActive"), CheckBox)
End If

The check mark works fine when not in edit mode. But when in edit mode, the row that is being edited works as expected. But the other rows now show True or False. I want them to have the const HeavyCheckMark in it instead.

Forms Data Controls :: Gridview RowDataBound Event - Set Default Value

May 17, 2010

When a Gridview row is in edit, I need to default an empty textbox to today's date. I am close, but the defaulted date is is not saved to the database. I can key in the date and the date is displayed and saved to the database. Even more interesting:

1. The date is defaulted to - 5/17/2010
2. If I erase the month and key the "5" back in the data is not saved.
3. If I erase the month and then change the month to "6", the data is saved to the database. If any value is changed in the date the save works.

Forms Data Controls :: Decrypting SQL Column On RowDataBound In GridView?

Mar 24, 2010

I have an internal web application which uses a custom encryption class to convert strings to varbinary(50) columns in SQL. When I display the table in a GridView, I want to use the RowDataBound event to decrypt the encrypted column back to a string to display.

Currently I have the following in my RowDataBound event:

[Code]....

This throws an exception when I try to load the page: TransformFinalBlock - Length of the data to decrypt is invalid.

I have tried just fetching the data from SQL in my query but the e.Row.Cells(3).Text evaluates to System.Byte[], so I tried using CAST([EncrytedColumn] AS varchar(50)) to convert the varbinary(50) to varchar(50), but this still resulted in the same exception being thrown.

My only solution so far has been to manually fetch the SQL data into a DataTable and decrypt the column before displaying it in the GridView, but I prefer the automated method of binding the SQLDataSource to the GridView.

Forms Data Controls :: GridView's RowDataBound Event Fired Twice?

Apr 20, 2010

I have a very simple asp.net page, just some buttons and one GridView on it. The logic is a user click the QUery button,then the button click event was trigured to populate the gridview with data queried from database via LINQ. for a user friendly interface, in RowDataBound event, I visit every row, change a boolean value into checkbox represention. But it seem that the RowDataBound run twice, because the checkboxs were inserted twice for every row in one cell. so why? the source code snippet as follow:

protected void btnSelect_Click(object sender, EventArgs e)
{
RetiredEmployeeDataContext db = new RetiredEmployeeDataContext();
GridView1.DataSource = db.ENTUserAccountSelectAll();//userAccounts;
GridView1.DataBind();
}
protected void GridView1_OnRowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
CheckBox chkActive = new CheckBox();
chkActive.Checked = ((ENTUserAccount)e.Row.DataItem).IsActive;
chkActive.Enabled = false;
e.Row.Cells[5].Controls.Add(chkActive);
}
}
