</div>
that gridview is in a webuser control with other cotrols and divs, everythings show as it should but the gridviews
this is the code on the onload event
If Not Page.IsPostBack Then
dim dgv1datatable as new DataTable
With dgv1datatable
.Columns.Add(New DataColumn("ID", GetType(Integer)))
.Columns.Add(New DataColumn("Descripcion", GetType(String)))
.Columns.Add(New DataColumn("Monto", GetType(Double)))
.Columns.Add(New DataColumn("Fecha", GetType(Date)))
End With
Session("dgv1dt") = dgv1datatable
dtgrid1.DataSource = DirectCast(Session("dgv1dt"), DataTable)
dtgrid1.DataBind()
dtgrid1.Visible = True
End If
but it's now showing the gridview but if i insted place the gridview where the placeholder should be the gridview shows any help please?
EDIT
im going to try and explain better the issue
this is where the gridview should've within a webusercontrol that is in a placeholder
so since it wasn't showing i decided to delete the placeholder and place the gridview in the same place and it did appear
<asp:SqlDataSource ID="SqlDataSource1" runat="server" CacheExpirationPolicy="Sliding"
ConnectionString="<%$ ConnectionStrings:catalog %>"
SelectCommand="SELECT * FROM YourDB"></asp:SqlDataSource>

This is my Grid view. I want to know how to bind data to Text boxes and drop down list using Row command event.

This is my code behind part.
protected void BuyerGrid_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Edit")
{
int index = Convert.ToInt32(e.CommandArgument);
//Bind values in the text box of the pop up control
tbxBuyerName.Text = BuyerGrid.Rows[index].Cells[0].Text;
tbxBuerCode.Text = BuyerGrid.Rows[index].Cells[1].Text;
//.Text = gview.Rows[index].Cells[2].Text;
}
}
Change
CommandArgument='<%#Eval("BuyerId") %>'
to
CommandArgument='<%# Container.DataItemIndex %>'
or
CommandArgument='<%# Container.DisplayIndex %>'
Is it possible to add expand colapse functionality in a nested grid view without using Jquery or java script.
If yes can someone give me an example?

You can use the asp.net ajax toolkit. Which still uses javascript, but you don't have to do any of it yourself. It's all done under the hood.

Here is the collapse/expand panel extender

I have Required field validator when i am trying to insert manually when i removed the Required field validator can someone tell me what's happening?
Firstly you need to implement the RowEditing event on the gridview to enable editing, MSDN definition:
Occurs when a row's Edit button is clicked, but before
the GridView control enters edit mode.
ASPX:
<asp:GridView
ID="gvCustomers"
runat="server"
OnRowEditing="gvCustomers_RowEditing">
Code behind:
protected void gvCustomers_RowEditing(object sender, GridViewEditEventArgs e)
{
gvCustomers.EditIndex = e.NewEditIndex;
//Re bind the grid view
}
Now if this event is not being fired when you click the Edit link on your grid view it means that there is some validation logic on the page which is preventing a post back.
The best way to get rid of this issue is to set the ValidationGroup attribute, for the validation controls causing trouble(not the gridview):
<div id="insertEmployee">
<asp:TextBox ID="txtName" runat="server" ValidationGroup="Insert" />
<asp:RequiredFieldValidator ID="rfvName" runat="server" ControlToValidate="txtName" ErrorMessage="Name is required" ValidationGroup="Insert" />
<asp:Button ID="btnAdd" runat="server" Text="Add" ValidationGroup="Insert" />
</div>
I am using this method to retrieve company from trade. How can I display company ID on GridView? This is my code to retrieve.
public List<Trade> getTrade()
{
List<Trade> trades=dbContext.trades.Include("tradeCompany")
.OrderBy(t => t.tradeDate).ToList();
return trades;
}
I bind to List at code behind... This is my gridview
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
BackColor="White" OnRowDataBound="sharesGridView_RowDataBound" BorderColor="#999999" BorderStyle="None" BorderWidth="1px"
CellPadding="3" GridLines="Vertical">
<AlternatingRowStyle BackColor="#DCDCDC" />
<Columns>
<asp:BoundField DataField="tradeDate" DataFormatString="{0:MMMM d, yyyy}"
HeaderText="Date" HtmlEncode="False" SortExpression="tradeDate" />
<asp:BoundField DataField="type" HeaderText="Type" SortExpression="type" />
<asp:BoundField HeaderText="Company" />
<asp:BoundField DataField="tradePrice" HeaderText="Price"
SortExpression="tradePrice" />
<asp:BoundField DataField="tradeQuantity" HeaderText="Quantity"
SortExpression="tradeQuantity" />
</Columns>
<FooterStyle BackColor="#CCCCCC" ForeColor="Black" />
<HeaderStyle BackColor="#000084" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#999999" ForeColor="Black" HorizontalAlign="Center" />
<RowStyle BackColor="#EEEEEE" ForeColor="Black" />
<SelectedRowStyle BackColor="#008A8C" Font-Bold="True" ForeColor="White" />
<SortedAscendingCellStyle BackColor="#F1F1F1" />
<SortedAscendingHeaderStyle BackColor="#0000A9" />
<SortedDescendingCellStyle BackColor="#CAC9C9" />
<SortedDescendingHeaderStyle BackColor="#000065" />
</asp:GridView>
Instead of using a BoundField you can use a template field:
<asp:TemplateField>
<itemtemplate>
<p><%#DataBinder.Eval(Container.DataItem, "Company.Id")%></p>
</itemtemplate>
</asp:TemplateField>
in asp.net, when you have an autogenreated select button on a gridview, is it possible to change the text of it from 'select' to something else of your choosing? If so can anyone point me to an example?
thanks again
