How To Set An Unbound GridView Column To Invisible In Code

Apr 4, 2011

Dim Application = From AL In db.AnnualLeave _
Where AL.Approval <> True _
Select LeaveID, EmpID, Name
GridView3.DataSource = Application
GridView3.DataBind()

after calling `GridView3.DataBind(), why do i still get Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index.

at this line of code GridView3.Columns(1).Visible = False yet the grid has rows and more than 2 columns. i found a thread about similar problem here [URL] Note that the Gridview columns have NOT been defined at design time.

Getting The Value Of An Invisible Column On Row Bound In A GridView?

Aug 11, 2010

I have an ASP.NET GridView control in a Web Form. For the sake of simplicity, I will say that this GridView is defined as follows:

[code]...

When each of these rows is bound (a.k.a. during the "myGridView_RowBound" event), I want to get the ID, Name, and Age values. My problem is, I cannot figure out how to get the "ID" value. The reason why is because it is in an invisible field.

C# - Gridview Making A Column Invisible?

Jun 17, 2010

I have a grid view which is dynamically generated via C# using a DataSet. I'm passing a row ID field (from the database) to the grid view, as this is required when a user clicks to edit a records. However I don't want the user to be able to view the column.I have tried the following but it doesn't seem to work? hide the column or a better way of attaching the information to the grid view row so it can be used at a later stage. c#

DataColumn ColImplantCustomerDetailsID = new DataColumn();
ColImplantCustomerDetailsID.ColumnName = "Implant ID";
ColImplantCustomerDetailsID.DataType = typeof(int);
ColImplantCustomerDetailsID.Visable = false; <-- visable doens't work here.

Data Controls :: How To Make A Column Invisible In GridView Control

Jan 25, 2013

I bound the gridview having some fields(ID, StudName, City)  and Display Button. When I click on the Disply button I approve the student and updation will happen. 

Bu what happen the column ID is not in the sequence. Sometime it displays 1,2,3,4,5,6 ...  next time it will display 7,8,9,10,11.... I want a sequence for the column ID. For that I used : 

<%# Container.DataItemIndex+1 %>

and it is working fine.. But again I realize that these numbers are generating at runtime and i can't refer to that student. Also I don't want to display ID column on the grid view but I want to use on runtime generated column. [ i am using RowCommand for ID column ] How it is possible?

Forms Data Controls :: Datalist - Unbound Label Assigning Text In Code Behind

May 20, 2010

The Datalist is being databound via an ObjectDataSource and everything here works fine. I have a label which I've added to my datalist and it's unbound to anything. Depending on the message information, I want this unbound label to display a certain phrase but it has to be next to a bound label. But if I try to change the text of the label in the code-behind, VS2k8 reports that the label is not declared. How do I do this?

Forms Data Controls :: Unbound Gridview Row Modify In Rowdatabound Don't Edit?

Mar 2, 2011

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

Invisible Borders In HTML Table Not Quite Invisible?

Sep 11, 2010

I have some tables in my asp.net mvc application for layout purposes. Even though I usually use divs for most things, in some cases tables make most sense because they already have exactly the layout I'm after in these cases.

The only problem is, as far as I know the borders are supposed to be invisible unless you specify a width and style for the borders. But they aren't... They are rather vague, yes, but there are still light blue borders around each cell. What is that and how do I get rid of them? (Funny thing is I don't remember having seen this before when I used tables, which was a while ago).

I also tried specifically setting the border to 0px on both table and td, but that didn't work either...

I am currently trying to do it through a switch statement on the sort expression to determine what column it's coming from but I am unaware of how to set the css class.
