Forms Data Controls :: Add Associated Control Id For Gridview Fotter Template Under Section 508?
Mar 15, 2011
I have gridview template field with 5 columns like First Name, Middle Name, P.No and Last Name. The grid has a list of people with a blank row at the bottom of the grid (in the footer) that allows the user to add a newperson to the list. I have added textbox under fotter template. i need to add associated control id for footer template text box.I have been asked to make the grid section 508 compliant. The requirement is that the column headers must have labels that referencethe text boxes in the footer row. On a normal web form it would look like this:
This allows a text reader to figure out that the words "First Name" are associated with the text box "txtFirstName" and helps a blind personunderstand how to fill out the form.Now, back to my problem. I need to figure out a way to get the header of a Grid view template column to work the same way. The biggest problem is that I have no idea what the ClientID of the textbox will be.
I have a gridview and basically at page load I want it to display with an empty row. The first field in the gridview would be a template field containing a textbox. I wan't to be able to type in, for example, a product code ('abc'). This would be the parameter for the stored procedure and then the rest of the columns (40+ additional columns) in the gridview would populate with the rest of the data pertaining to that product code (i.e. price, unit of measure, etc.). In short the template field texbox is the control to bind the gridview.
After the row is populated I could click a button or link that would add that entire row to my gridview and then add another empty row where I could enter another product code... populate the row then add that row to the gridview. and so on...
like this in a function in AddColumns button clickevent
gv.Columns.Clear() Dim chkCol As New TemplateField chkCol.ItemStyle.Width = 20 chkCol.ItemStyle.HorizontalAlign = HorizontalAlign.Center gv.Columns.Add(chkCol)
2)
and in row databound event i added checkbox control to this template field. like this
Protected Sub gv_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gv.RowDataBound If e.Row.RowType = DataControlRowType.DataRow Then Dim chkbox As New CheckBox chkbox.ID = "chkSelect" e.Row.Cells(0).Controls.Add(chkbox) End If End Sub
HERE I WANT TO GET CHEKC BOX IN btnok click event
Protected Sub btnOk_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnOk.Click Dim linkId As String Dim summary As String = "" 'Enumerate the GridViewRows For index As Integer = 0 To Me.gv.Rows.Count - 1 'Programmatically access the CheckBox from the TemplateField Dim cb As CheckBox = CType(gv.Rows(index).Cells(0).FindControl("chkSelect"), CheckBox) If cb IsNot Nothing Then If cb.Checked Then linkId = Me.gv.DataKeys(index).Value End If End If Next Me.Page.Title = linkId End Sub
But here i am not getting Check box even i used find control. how i get checkbox
Setting up the editItem template of a gridview. I have a template field with a dropdown list for editing. When the gridview goes into edit mode the dropdown list is displayed with all the right options but the current value of the field (pre-editing) is not the selected value of the dropdown list? How do I make that happen? I have a couple fields where the editItem template will use a dropdown list and I'm sure a user will not realize those values have changed and they will just edit what they intended to edit and save the changes, inadvertently also making changes to other fields.
I'm trying to change one section in code from DataGrid format to GridView format. The reasoning is that the sample application that was displayed was using a DataGrid even though it should have been using a Gridview for 2.0 and above. Most of it shows up without an error except one line in 3 lines which are pretty much the same. I bolded them and just want to know how do I re-write them for the Gridview?
Protected Sub NewsGrid_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles NewsGrid.RowCommand Dim connection As SqlConnection = CreateConnection() If e.CommandName = "Delete" Then Dim com As New SqlCommand("DELETE FROM ElectPageEditor WHERE NewsID = @NewsID", connection) com.Parameters.AddWithValue("@NewsID", e.Item.Cells(0).Text) Try connection.Open() com.ExecuteNonQuery() Catch generatedExceptionName As SqlException Finally connection.Close() End Try ElseIf e.CommandName = "Edit" Then Dim command As New SqlCommand("SELECT NewsText FROM ElectPageEditor WHERE NewsID = @NewsID", connection) command.Parameters.AddWithValue("@NewsID", e.Row.Cells(0).Text) Try connection.Open() Dim record As SqlDataReader = command.ExecuteReader(CommandBehavior.CloseConnection) If record.Read() Then NewsEditor.Content = record.GetString(0) EditedNews.Value = e.Item.Cells(0).Text lse NewsEditor.Content = "" EditedNews.Value = "" End If ' Will close the connection as well record.Close() Catch generatedExceptionName As SqlException Finally connection.Close() End Try End If ' Add code to delete row from data source. ReadAllRecords() End Sub
I have gridview with div tag, i have put div tag becouse when user scroll in grid i dont want move grid header section. Its remaining ther and only move data section. Its working fine.
But my datagrid has facility to master details hiearchy of data, When user click one of button its expand details record of that particular parent item.
When user click expand button my gridview header section jump to top of page. How can i stop it
I had problems with using the gridview. For example I can bind or a a row of data to the gidview but the column data in the details section does not line up appropriately as far as justification with the grid view headers. I have tried different alignment combinations but that does not work.
I have grid view control that includes a dropdown control in a template field.I wish to execute some code when the value is changed in the dropdown list. Can't figure out how to capture this event though?
I have seen a number of posts on this, but none that quite serve my needs. I have a GridView with template fields. I use postback because when a value is entered in one field a calculation is done to supply the value in another field. I simply loop through all the rows after each postback (there are not many so it is fast). I do not use a select command or button to select a row. After postback I do not know how to return the focus to the row that was being used. I can return the focus to the first row just by using gridview1.focus.
i am implementing a update query module.i am displaying all fields from a table for a term searched. well now i am implementing update option for the record which are displayed, i have like 70 columns in my table, and i want to know how to restrict some selected fields to be only read only while the form can be updated ?Like if user select to update a record then some selected field such as "Timestamp, UID etc some selected fields" remains READ ONLY !
I need to be able to evaluate the text value of the template button or pass date from the dbDateOpened colum when the button is pressed. Either direct I have tried gives me an compile error. With the current configuration I get this error. "Object reference not set to an instance of an object."
I have a problem....my password recovery control is not going into Question Template section ....It was working fine for a couple of days before but for some weird reason it stopped working.....Whenever i click the submit button it directly goes and calls the PasswordRecovery1_SendingMail function(it doesn't ask any password recovery question)
How could I change (programmatically) a couple of properties in a grdiview template ? For instance, the CalendarExtender6.enabled and the textbox, Duetext.readonly.
I have a field that is based on asp.net membersip UserID. I can bind this to dropdowns which aren't in a detailsview just fine, but for somereason my code isnt working for finding the control properly.I have the following in detailsview.databound (where it was suggested to be placed)
I am using FindControl to get a hyperlink but it only works on the first page. It works fine until I click on another page number in the pager. Then the hyperlink is nothing. This is the hyperlink.
i have a detailsview with a dropdownlist. i would like to be able to select a value from this dropdownlist and depending on the selectedvalue display a specific control/header in another column.
