You can use an ImageField, like so:
<asp:ImageField DataImageUrlField='<%# "ThumbNailImage.ashx?ImID="+ Eval("Picture") %>'></asp:ImageField>

This is my Grid view. I want to know how to bind data to Text boxes and drop down list using Row command event.
<asp:Panel ID="Panel2" runat="server" CssClass="mid">
<asp:GridView ID="BuyerGrid" runat="server" AutoGenerateColumns="False" DataKeyNames="BuyerId" CellPadding="4" ForeColor="#333333" GridLines="None" OnRowCommand="BuyerGrid_RowCommand">
<AlternatingRowStyle BackColor="White" ForeColor="#284775" />
<Columns>
<asp:BoundField DataField="BuyerName" HeaderText="Buyer Name" />
<asp:BoundField DataField="BuyerCode" HeaderText="Buyer Code" />
<asp:BoundField DataField="CountryName" HeaderText="Country" />
<asp:BoundField DataField="CityName" HeaderText="City" />
<asp:TemplateField HeaderText="" SortExpression="">
<ItemTemplate>
<asp:LinkButton ID="LinkButtonEdit" runat="server" CommandName="Edit"
CommandArgument='<%#Eval("BuyerId") %>'>Edit</asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
</Columns>
<EditRowStyle BackColor="#999999" />
<FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
<HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" />
<RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
<SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" />
<SortedAscendingCellStyle BackColor="#E9E7E2" />
<SortedAscendingHeaderStyle BackColor="#506C8C" />
<SortedDescendingCellStyle BackColor="#FFFDF8" />
<SortedDescendingHeaderStyle BackColor="#6F8DAE" />
</asp:GridView>
</asp:Panel>
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 %>'

I tried everything I could think of, and, naturally, I searched it online.
When I click on Insert, the value (0) is simply inserted, no questions asked.
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

every thing is working fine but, the problem is in the footer templalte dropdownlist is added after all the 4 columns but i want to add the dropdown footer to the 2nd column(Name).
Please apologise for my english n Help me
I used the following code:
<asp:GridView ID="gv_page2" runat="server" AutoGenerateColumns="False"
BackColor="White" BorderColor="#999999" BorderStyle="Solid" BorderWidth="1px"
CellPadding="3" ForeColor="Black" GridLines="Vertical" ShowFooter="True">
<AlternatingRowStyle BackColor="#CCCCCC" />
<FooterStyle BackColor="Black" />
<HeaderStyle BackColor="Black" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#999999" ForeColor="Black" HorizontalAlign="Center" />
<SelectedRowStyle BackColor="#000099" Font-Bold="True" ForeColor="White" />
<SortedAscendingCellStyle BackColor="#F1F1F1" />
<SortedAscendingHeaderStyle BackColor="#808080" />
<SortedDescendingCellStyle BackColor="#CAC9C9" />
<SortedDescendingHeaderStyle BackColor="#383838" />
<Columns>
<asp:BoundField DataField="PRO_ID" HeaderText="PRO_ID" />
<asp:BoundField DataField="NAME" HeaderText="NAME" ItemStyle-Width="100px"/>
<asp:TemplateField HeaderText="Quantity">
<ItemTemplate> <asp:TextBox runat="server" Width="100px"></asp:TextBox></ItemTemplate>
</asp:TemplateField>
<asp:BoundField HeaderText="PRICE" ItemStyle-Width="80px"/>
<asp:BoundField HeaderText="TOTAL_PRICE"/>
<asp:TemplateField>
<FooterTempenter code herelate >
<asp:DropDownList ID="ftrDDL" runat="server" DataTextField="PRO_ID" AppendDataBoundItems="true" DataSourceID="" Width="130px" EnableViewState="true" >
<asp:ListItem Text="SELECT ONE" Value=""></asp:ListItem>
</asp:DropDownList>
</FooterTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
you need to modify the template of second column
<asp:TemplateField HeaderText="Name">
<ItemTemplate>
<asp:Label ID="lblName" Text='<%# Databinder.Eval(Container.DataItem,"Name") %>'
runat="server" Width="100px"></asp:Label></ItemTemplate>
<FooterTemplate>
<asp:DropDownList ID="ftrDDL" runat="server" DataTextField="PRO_ID" AppendDataBoundItems="true"
DataSourceID="" Width="130px" EnableViewState="true">
<asp:ListItem Text="SELECT ONE" Value=""></asp:ListItem>
</FooterTemplate>
</asp:TemplateField>
I have not tested the code but this should work .Let me know if it did not work
Is it required you add the drop down list in the footer?
I would suggest adding the drop down to the Name column. The footer will always load last.
Use template filed for Name
<asp:GridView ID="gv_page2" runat="server" AutoGenerateColumns="False" BackColor="White"
BorderColor="#999999" BorderStyle="Solid" BorderWidth="1px" CellPadding="3" ForeColor="Black"
GridLines="Vertical" ShowFooter="True">
<AlternatingRowStyle BackColor="#CCCCCC" />
<FooterStyle BackColor="Black" />
<HeaderStyle BackColor="Black" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#999999" ForeColor="Black" HorizontalAlign="Center" />
<SelectedRowStyle BackColor="#000099" Font-Bold="True" ForeColor="White" />
<SortedAscendingCellStyle BackColor="#F1F1F1" />
<SortedAscendingHeaderStyle BackColor="#808080" />
<SortedDescendingCellStyle BackColor="#CAC9C9" />
<SortedDescendingHeaderStyle BackColor="#383838" />
<Columns>
<asp:BoundField DataField="PRO_ID" HeaderText="PRO_ID" />
<asp:TemplateField HeaderText="Name">
<ItemTemplate>
</ItemTemplate>
<FooterTemplate>
<asp:DropDownList ID="ftrDDL" runat="server" DataTextField="PRO_ID" AppendDataBoundItems="true"
DataSourceID="" Width="130px" EnableViewState="true">
</asp:DropDownList>
</FooterTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Quantity">
<ItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Width="100px"></asp:TextBox></ItemTemplate>
</asp:TemplateField>
<asp:BoundField HeaderText="PRICE" ItemStyle-Width="80px">
<ItemStyle Width="80px"></ItemStyle>
</asp:BoundField>
<asp:BoundField HeaderText="TOTAL_PRICE" />
</Columns>
</asp:GridView>
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>
