Forms Data Controls :: GridView.RowDataBound Equivalents In DetailsView And FormView Method
May 4, 2010
Is there an equivalent of the GridView.RowDataBound event for the DetailView and FormView controls in ASP.NET 3.5?I need to manipulate data after Selecting it from my database, but before it gets presented to the user. I've read the documentation but I think I've missed something because I can only find FormView.DataBound which is called after the entire control has been data bound. Something like an ItemDataBound event would be what I need....?!?

I am using VS 2008 SP1. My also have included CSS Friendly adapter [URL] in my project ( I mentioned this because my GridView Empty data template is not showing when using GridView's CCS Friendly adapter). I have a GridView and a DetailsView. When a record in GridView is selected its details information is shown in the Details View. Type of Data source I am using is ObjectDataSource. My Insert and Update methods works perfectly. It is only the Delete method that is passing null values to the underlying object delete method. My source codes for both the UI, BLL, DAL is shown below

Is Sqldatasource powerful? Is there any disadvantage using it over other controls?
And How to use Sqldatasource from code behind with datacontrols like gridview,detailsview and formview?
Is it possible to completely customize the gridview using sqldatasource from code behind?

I´m trying to link the gridview to detailsview and I used this page as my inspiration:
http://quickstarts.asp.net/QuickStartv20/aspnet/doc/ctrlref/data/detailsview.aspx
But I´m trying to do that programmatically, not with the sqldatasource. So I wrote the method that binds data to Detailsview and I call it in the page_load. The problem is that I have to click two times on the select button to view the detailsview. The first time I click on the select button nothing happens.

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.

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.

I've been pickling my brain trying to do this for a couple of days but to no avail. I have the following in "FormView1" which I'm just using in insert mode:
<td class="style4">
<asp:TextBox ID="urlTextBox" runat="server" Text='<%# Bind("url") %>' CausesValidation="True" Width="200px" />
</td>
I'd like the contents (i.e. whatever the user wants to insert) to be passed to a method where it will be checked against any existing values in the database.

I am using a gridview to select a record and control that record using a details view. I am using a class based objectdatasource to link the data for select, update and delete. Sofar the select works but the update fails. Here is my error message:
ObjectDataSource 'odsDetailsView_1' could not find a non-generic method 'UpdateSet' that has parameters: setId, TYPE, iHPlayer, iAPlayer, iHRuns, iARuns, iH8Break, iA8Break, iHe8s8, iAe8s8, iH15BRn, iA15BRn, iHWins, iAWins, SET_ID, MATCH_FK, HOME_MEMBER_ID_FK, AWAY_MEMBER_ID_FK, HOME_TABLERUN, AWAY_TABLERUN, HOME_8BALLBREAK, AWAY_8BALLBREAK, HOME_E8S8, AWAY_E8S8, HOME_15BRN, AWAY_15BRN, HOME_TOTALWON, AWAY_TOTALWON, HOME_POINTS, AWAY_POINTS, LOCKED, GROUP_FK.
The first group of parameters have lower case letters and they come from my objectdatasources update method parameters. The second group of parameters are all capitalized and they are the fields in my SQL database table (and I don't know how they wound up in the error). This might be a clue.When executing the code my class method never gets the chance to execute because the error pops up before the code gets there.
Here is my objectdatasource:

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.

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.

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.

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.

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);
}
}

I have a Customer database table with a text field named customerPicture with the name of the JPG file.
I have made a Customer Entity class with the LinQ to SQL Designer.
I also have a FormView displaying Customer instance binding with a LinqDataSource.
My problem is:
I want to make some modifications when some control want to bind the customerPicture field.
For example, when my FromView want to show the field customerPicture I want to return not only the JPG file name, I want to modify this string to add the complete file path and perhaps resample the image to a determinate width and height.
I know that is posible to defeine a partial class named Customer to implement certains partial methods, like OnCustomerPictureChanged(), but I dont know how to do this.
If I make, in this Customer partial class, a new method, for example getResamplePicturePath(), how could I invoke it from a FormView?

i use a gridview to show data from datasource, but i have some column in this gridview that they're not bound. If i go in edit mode, my unbound control show me the textbox to enter value and its ok, but if i modify value thru rowdatabound, now when i go in edit mode, the textbox are not showing as i expect, its just showing the value i put in rowdatabound, but i don't have the textbox to let me enter a new value and update it after.
And more in the same relation: with the two above condition i wrote, when i dont modify value in rowdatabound, i can modify value in prerender event with this line:
TextBox
box1 = this.GridView1.Rows[this.GridView1.EditIndex].FindControl("TextBox1")
as
TextBox;
box1.Text = "a value"
;
but
when again i modify value in rowdatabound, the line above will not work too, box1 is load with a null value
