I would like the rows of my GridView to have strikethrough based on a bound data value called IsObsolete. I tried to do this:
<RowStyle BackColor="#EFF3FB" Font-Strikeout='<%# Bind('IsObsolete') %>' />
But obviously this doesn't parse. I'd rather not do this in GridView.DataBound().
As a workaround for the fact that asp:Checkboxes don't have values, I am attempting to dynamically create the ID's of checkboxes in a DataList so that it inserts the primary keys into the control ID. This is surprisingly difficult.
I have placed a PlaceHolder in my DataList ItemTemplate, then in the ItemCreated I create the checkboxes using string.Format("Checkbox{0}", DataBinder(e.Item.DataItem, "ID")). The problem is that this only works in a non-postback condition, as on postback the DataItem is null. And of course ItemDataBound isn't called on PostBack so that won't work either.
I can't seem to find a good way to handle this short of if (IsPostback) dataList.Bind(), which i don't think is a good way to do it.
Can anyone provide me with any alternatives here?

View 1 RepliesI have a bound datagridview with the associated tableadapter, dataset and bindingsource. A different component in our application can add or delete rows displayed by the datagridview. When this happens, the underlying database edits are correct. The problem is that the datagridview seems to lose track of the data.
Currently, when we receive the event that our data has changed we do the following.
this.DataSet.Offers.Clear();
this.TableAdapter.Fill(this.DataSet.Offers);
this.BindingSource.ResetBindings(false);
this.DataGridView.Refresh();
If our example had something like 5 items displayed in the grid and a row was deleted, the grid refreshes with 3 items shown. If we manually refresh our grid through a button calling the exact same code, it displays the correct results. Is this an asynchronous call? Should we be refreshing the grid in a different area?
If the gridview binds to empty dataset, I need to still show a gridview so that users can ADD more using the textfields in the bottom of the footer template. Since the gridview is empty it won't bind not allowing rendering of the <footer template> I guess I should create a empty dataset if the gridview is empty. How do I check for this and can this be done in GridviewRowEventArgs

How to open a new row to existing GridView? and still keep original data?
This was a pretty disappointing moment - when databinding, using Eval("Contact.LastName") would work. It nicely evaluates the related Linq object's member LastName. If the "Contact" object is null, no error is thrown... instead the field is simply null.
However, the same does not hold for sorting - if there exists a null entry (this object does not have a Contact) then the LinqDataSource throws a NullReferenceException. This means that, if you ever have nulls on your foreign-key objects, you can't use sorting headers in the ListView.
This makes the feature moderately useless - I have to roll my own properties for every single field I'd ever want to sort on. That's insane.

So far so good. But where is no data is not returned from the database, I want to display something on the page saying "No data returned". But I don't know which gridview control event gets fired so that I can write some code in it to check if the records returned are zero.
I'm trying to add a row grouping row to my data-bound gridview. It works fine on the first response, but at the postback i got the "Failed to load viewstate" error.There is the code for the GridView's RowDataBound event:
Private Sub AddGroupingRow(ByRef eRow As GridViewRow, ByVal Css As String, ByVal ColSpan As Integer, ByVal Txt As String)
Dim cell As New TableCell()
cell.ColumnSpan = ColSpan
cell.CssClass = "Spacing FieldCell"
cell.Text = Txt
Dim row As New GridViewRow(-1, -1, DataControlRowType.DataRow, DataControlRowState.Normal)
row.CssClass = Css
row.Cells.Add(cell)

I have a query expression which I am binding to a GridView in Page_Load. The data I want to capture in the SelectedIndexChaned event is in a BoundField defined thus:
<asp:BoundField DataField="ID" HeaderText="ID" ReadOnly="True"
SortExpression="ID" Visible="False" />
If I set Visible="True", I have no trouble getting this data. Is there a way to hide the ID field and still get the data?
I have a foreign key (TeamID) in a GridView. I use a TemplateField to display it as the lookup value (TeamName) in a label, and a dropdown for editing. When row is selected and SelectedIndexChanged is fired, I want to access the TeamID. I can get the TeamName from the label. I tried putting the TeamID in DataKeyNames, but that fouled up my dropdown when saving (it reverts to the original value). So, how can I get the TeamID?

The gridview columns comes dynamically for each time.
I am looking for a method to format gridview bound data using javascript.
I know you can have custom formating in Eval using:
[Code]....
But I am looking for a way to perform this task on client side, rather than doing it on the server.
For example if I want to format a date field being bound in a custom way, something like emails date received in gmail. (Only show time if it is today's date [15:30] and only show day and month if it is this year date [14 Jan] and show the full date if it is not this year [10/10/2009].
So, how I use javascript to format a field (ie. custom date format or setting a control visibility)?

I have a gridview being data bound by an objectdatasource which points to a BLL/DAL. I have paging and sorting enabled within the gridview. I have the fields configured in the look/fell I want from a templatefield. This templatefield has the sort expression (date) I want things to be sorted by. All this works as it should and I have no issues with it.But, the issue is that when I click on the header to sort asc/desc by date, I have to click on it twice for it switch to descending order. E.g. I hit the webpage and it lists all the information in the gridview, sorted by date, ascending order. If I want to sort by descending order, I have to click the date header twice in order for the gridview to sort the information in descending order; the clicks cause a post-back and the whole screen is refreshed.
View 2 RepliesI have a GridView control that has one column of checkboxes set up like this:
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="RowCheckBox" runat="server" Enabled="false" Checked='<%# (bool)DataBinder.Eval(Container.DataItem ,"Associated") %>'/>
</ItemTemplate>
</asp:TemplateField>
Then when the user clicks an Edit button I run a script that enables all the checkboxes (which works fine), and then when the user then clicks on a checkbox the tick is appearing or disappearing as it should.
The problem I'm having is that when I try to read the value of the checkbox from the codebehind:
CheckBox checkBox = (CheckBox) row.FindControl("RowCheckBox");
bool checked = checkBox.Checked;
If the value bound to it was true then checked is still true, no matter if it was toggled or not.
Edit: Corrected a spelling mistake. Question still stands though...
I have a Gridview that has a template field containing a bound textbox (fieldname is 'Status'). I have an extra column containing an update button, which is designed to update the db with whatever is in the textbox.
What's happening is that when I load the form, the textbox is blank, even though there is existing data in the fields. If however I click the update button, all the textboxes in the Status column update and populate with the correct data from the database. I guess my question is why would bound textboxes not populate until an update command is run?
