EditItemTemplate question

[NH]

How can I only display the textbox I have in an EditItemTemplate based on the
value in another cell in the row?

i.e I only want users to edit one of the cells based on the value in another
cell....

Should I do this in the ItemDataBound event of the datagrid...something
like...
If e.Item.Cells(8).Text = "2" Then
dont allow the textbox defined in the EditItemTemplate to be visible
what is the code for this?
End If

Thanks for your help

e.Item.Controls.FindControl("TextBox's Id").Visible = false;

thanks for the reply.

I get a "Object reference not set to an instance of an object" error with
the line
CType(e.Item.FindControl("txtDaysWriteOffed"), TextBox).Visible = False

Should the EditItemTemplate control be referenceable in the ItemDataBound
datagrid event? Its as if it doesnt know about the control?

i think it should be

CType(e.Item.Controls.FindControl("txtDaysWriteOff ed"), TextBox).Enabled =
False

Adding the 'FindControl' in there

Yeah this is something I tried also, get an ""Object reference not set to an
instance of an object" error.

It looks like the EditItemTemplate control is not referenceabnle in the
ItemDataBound event?

How about if you try that code in the EditCommand

private void DataGrid1_EditCommand(object source,
System.Web.UI.WebControls.DataGridCommandEventArgs e)

{

e.Item.FindControl("");

}

not sure the VB code for that, but accessed through the DataGrid property
'EditCommand'

GOT IT

After much fighting with Visual Studio - which kept removing my DataGrid
events, i found a way
In your EditCommand method, hide the Column you don't want to show,

So, if the TextBox will appear in Column 4, in you EditCommand Method do as
follows:

private void DataGrid1_EditCommand(object source,
System.Web.UI.WebControls.DataGridCommandEventArgs e)

{

DatGrid1.EditItemIndex = e.Item.ItemIndex;

BindTopicGrid(this.m_user);

if(e.Item.Cells(8).Text = "2" then

DataGrid1.Columns[4].Visible = false;

End If

}

Hi Grant,
I really appreciate all your effort on this. I really need to keep the
column visible, its just the txtbox in the EditItemTemplate. Anyway of
doin
it?

In your EditCommand method, hide the Column you don't want to show,

So, if the TextBox will appear in Column 4, in you EditCommand Method do
as
follows:

private void DataGrid1_EditCommand(object source,
System.Web.UI.WebControls.DataGridCommandEventArgs e)

{

DatGrid1.EditItemIndex = e.Item.ItemIndex;

BindTopicGrid(this.m_user);

if(e.Item.Cells(8).Text = "2" then

DataGrid1.Columns[4].Visible = false;

End If

}

Again, HTH

thanks for the reply.

I get a "Object reference not set to an instance of an object" error with
the line
CType(e.Item.FindControl("txtDaysWriteOffed"), TextBox).Visible = False

Should the EditItemTemplate control be referenceable in the ItemDataBound
datagrid event? Its as if it doesnt know about the control?
The control only exists when e.Item.ItemType = ListItemType.EditItem. The
ItemDataBound event is triggered for all ListItemTypes but your textbox only
exists for the EditItem.

All you need to do is just add an if statement like this:
If e.Item.ItemType = ListItemType.EditItem Then
If Not e.Item.FindControl("txtDaysWriteOffed") is Nothing then
CType(e.Item.FindControl("txtDaysWriteOffed"), TextBox).Visible =
False
End If
End If

How can I only display the textbox I have in an EditItemTemplate based on
the
value in another cell in the row?

i.e I only want users to edit one of the cells based on the value in
another
cell....

Should I do this in the ItemDataBound event of the datagrid...something
like...
If e.Item.Cells(8).Text = "2" Then
dont allow the textbox defined in the EditItemTemplate to be
visible
what is the code for this?
End If

Thanks for your help

[Grant Merwitz]

Just posting here to keep your other post clean

Can you post me some of your code?
This really shouldn't be so difficult - certainly not a 48 hour problem
