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.
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?
No sense in showing a competely blank column. how to make a GridView column invisible if every cell in that column is empty?
View 3 RepliesHow do I make a column invisible in a gridview? I tried to use this:
dataGridView.Columns(0).Visible = False
But its getting an error "Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index". How can I do this?
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.

How do I pass a GridView column value to the code behind with out making it visible? In the following code, I would like to capture the ContactID with out making it visible in the GridView.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="SqlDataSource1"
OnRowCommand="_OnRowCommand"
>
<Columns>
<asp:BoundField DataField="ContactID" HeaderText="ContactID"
SortExpression="ContactID" InsertVisible="False" ReadOnly="True" />
.....other columns in the grid....
<asp:ButtonField ButtonType=Button CommandName="Remove" Text="Remove" />
</Columns>
</asp:GridView>
I would like to capture ContactID as follows. I can not do so with out making it visible = true in the GridView.
if (e.CommandName.Equals("Remove"))
{
int index = Convert.ToInt32(e.CommandArgument);
int ContactID = Convert.ToInt32(GridView1.Rows[index].Cells[0].Text.Trim());
}
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.
I m getting 9 columns from database in a dataset but I want to diplay only 4 columns in datagrid. Remaining 5 columns values, I want to display in the textboxes below datagird.
I tried it making column invisible. If I make it invisible, I m not getting any value for that column to display in the textbox.
I bound the gridview having some fields(ID, StudName, City) Â and Display Button. When I click on the Disply button I approve the student and updation will happen.Â
Bu what happen the column ID is not in the sequence. Sometime it displays 1,2,3,4,5,6 ... Â next time it will display 7,8,9,10,11.... I want a sequence for the column ID. For that I used :Â
<%# 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?Â
regarding gridview Template column.in my template column i have a textbox and i need to invisible to user. but when i set visible property "false" then textbox value is not render.

I want to fix the gridview column width using bound field and also template field using vb.net ... How can i ?
View 1 RepliesI have a bound column.
<asp:BoundField DataField="WorkPreference" HeaderText="WorkPreference"
HeaderStyle-HorizontalAlign="Left">
<HeaderStyle HorizontalAlign="Left" />
</asp:BoundField>
dr["WorkPreference"] = sa.WorkPreference ( This is how I bind the data to a DataRow)
The example of the data which gets bound to this column is like the following:
Communications and Marketing Officers; Environmental Assessors; Geologists and Geosciences; Geospatial/Spatial Information Officers;
What I want is that the data should be presented to the user like the following:
Communications and Marketing Officers
Environmental Assessors
Geologists and Geosciences
Geospatial/Spatial Information Officers
In short: I basicaly want to put a break where there is a colon and then bind the data to the gridview. It looks like simple but if you can let me know.
I am having trouble with displaying double data in gridview bound coulumn. I want it to display as it is... But it gets rounded off when displayed.
Like my 1.34 displays 1.00
1.57 - 2.00
and so on. But i want it to display as it is i mean with decimal points, without rounding it off.
Below is the code behind for a simple aspx page. The web form contains one GridView (GridView1) and one label (Label1). I create a Data Table, then add a row to the table. I then DataBind my GridView to the DataTable. (so far so good) When I run the page I do see the GridView and the single row of data. However the checkbox shown is not enabled, meaning the user cannot uncheck or check it. (As if was not enabled)

I have a gridview control bound to a sqldatasource in c#. In the rowdatabound event I look at a value in a cell and use a function to evaluate the value and depending on that value I populate an added unbound column in my bound datagrid to show an excalmation point. I now want to sort by the column with the excalmation point.
View 2 RepliesI want to change the width of column in Gridview bound field but it is not changing. Code Is;
<asp:BoundField DataField="Address" HeaderText="Address" SortExpression="Address">
<ItemStyle Width="500px" />
</asp:BoundField>
in a data table contains columns such as id,firstname,lastname.then i will bind into grid view.
now i want to design the gridview like this,
<asp:BoundField HeaderText="Employee Code" DataField="id" />
<asp:BoundField HeaderText="Employee Name" DataField="FirstName"+""++ "MiddleName" />
how can i achieve it?
I have a grid that is built as well as populated dynamically through c# code. The grid has 3 columns(3 bound fields). And data is being populated in those bound fields through c# code programatically.
Elaborating my question: I have 3 bound field columns(col1, col2 & col3) . I have to increase the rowspan of col2 and col3 headertext's to 2 i.e I want the col2 and col3 header texts to span across two row cells. But the col1 header text should span across just 1 row. And the extra rowscell that is created under col1 due to the increase in the rowspans (of col2 and col3 boundfield headertexts) should be populated with some random text, i.e something like XXXXX
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 have a DataGrid with a TemplateColumn containing an asp:DropDownList and a BoundColumn. I'd like to have a VB.NET handler for when the selected item in the DropDownList changes. I'd like this handler to also update the value in the BoundColumn with the value of the newly selected item in the DropDownList.
Can someone point me to some resources I can examine to learn how to do this?
If the handler for the selection changing can give me the value of the NEWLY selected item, it should just be a matter of accessing the cell for my BoundColumn in the same row and writing to it. I do not know the syntax to achieve this.
I have a TextBox bound to a decimal column and want to drop any zeros to right of decimal point. So 8.0000 shows as 8 and 7.6000 shows as 7.6.Currently the Text property is #Bind("Units", "{0:n2}")
View 1 RepliesI have a dgv with a column type = DataGridViewAutoFilterCheckBoxColumn. I want to know if there's a way to I can get that entire column to become disabled (or Enabled = False) so it won't let the user click on the checkboxes.
I tried looking in the "Bound Column Properties" but there isn't an option to disable the entire column.
I'm trying to populate a date from a bound text field in a DetailsView. I keep getting a error when a DBNull is in the column. How do I avoid the DBNull when populating the text field.My code is as follows:

<EditItemTemplate>
<asp:TextBox ID="CBYDExpDate" runat="server" ReadOnly="true" Text='<%# IIf(Eval("CBYDDate") is DBNull.Value,"", String.Format("{0:MM/dd/yyyy}", Eval("CBYDDate").AddDays(30)))%>' />

I have a gridview control that has two bound fields. I want to restrict the user's to enter only numeric values in the second bound column. I went into the properties of the gridview control. Selected "Columns" and clicked on collection. The fields showed up.
I selected the field and clicked on the properties. I found DataFormatString property. can I restrict by making changes to this property?
