How to fix the columns of a gridview and the text of the cells in two rows

I'm developing a page to display information in a Gridview (ASP.NET), however as this page will be viewed on a smart tv I need the columns to be fixed and the texts of the cells to be restricted.
The RowStyle property with the Wrap as True and the Width property of the columns as a percentage.
Please, I would like a help, because if I change the Wrap to False the size of the GridView gets too large, popping the screen boundary and also could not find how to limit the text size of the cells to two lines.
Thanks in advance for your help and collaboration.

datagrid it is not showing in TabContainer

I have a ajaxtoolkit:TabContainer in my code. I put gridview inside it. but it is not showing the grid view when I run the project. gridview is fine and is showing data when it is not inside the TabContainer.
This is my aspx code:
<ajaxToolkit:TabPanel ID="tbAgency" runat="server" HeaderText="Agency" >
<ContentTemplate>
<asp:GridView ID="grAgency" runat="server" CellPadding="4"
ForeColor="#333333" GridLines="None" AutoGenerateColumns="False"

<SortedAscendingCellStyle BackColor="#F8FAFA" />
<SortedAscendingHeaderStyle BackColor="#246B61" />
<SortedDescendingCellStyle BackColor="#D4DFE1" />
<SortedDescendingHeaderStyle BackColor="#15524A" />
<Columns>
<asp:BoundField HeaderText="Agency Name" DataField="Name"
ItemStyle-Wrap="true" ItemStyle-HorizontalAlign="Center">
<HeaderStyle HorizontalAlign="Left" />
<ItemStyle HorizontalAlign="Left" Wrap="True"></ItemStyle>
</asp:BoundField>

<HeaderStyle HorizontalAlign="Left" />

</asp:BoundField>
<asp:BoundField HeaderText="Contact Name" DataField="ContactName"
ItemStyle-Wrap="true" ItemStyle-HorizontalAlign="Center">
<HeaderStyle HorizontalAlign="Left" />
<ItemStyle HorizontalAlign="Left" Wrap="True"></ItemStyle>
</asp:BoundField>
<asp:BoundField HeaderText="Contact Phone" DataField="Phone"
ItemStyle-Wrap="true" ItemStyle-HorizontalAlign="Center">
<HeaderStyle HorizontalAlign="Left" />
<ItemStyle HorizontalAlign="Left" Wrap="True"></ItemStyle>
</asp:BoundField>
</Columns>
</asp:GridView>
<asp:Button ID="btnAddAgency" Text="Add Agency" runat="server" />
<asp:TextBox ID="txtAgencySearch" runat="server" />
<asp:Button ID="btnSearchAgency" runat="server" Text="Search" />
</ContentTemplate>
</ajaxToolkit:TabPanel>
and this is my C# code that when the dropdown changes, it shows data in grid.(but grid is only visible when it is outside of the Tab, when I put in inside the Tab in disappears.
protected void ddlPartnerList_SelectedIndexChanged(object sender, EventArgs e)
{
Aid = Convert.ToInt32(ddlPartnerList.SelectedItem.Value);
if (Aid != 0)
{
Session["Aid"] = Aid;
TabContainer1.ActiveTabIndex = 0;
var AgencyList = adminmv.getAgency(Aid);
grAgency.DataSource = AgencyList;
grAgency.DataBind();
}
}

Put the GridView inside a ContentTemplate inside an UpdatePanel inside the ContentTemplate of the TabPanel and make sure you have a ToolkitScriptManager control on the page.
<tabPanel>
<contentTemplate>
<updatePanel>
<contentTemplate>
<gridview>

Identify the Access Key of a particular record in Gridview ,(For a button / TemplateField)

I am trying to have a gridview with dynamic data imported using a SqlDataSource , plus 2 TemplateFields containing 2 buttons as Accept and Decline.What I need to do is , update a specific column of the table where the records are coming from.(Change the value from Null to 1 or 0, in the column called "accepted")
Q.)I need a way to identify the row which the button will be clicked ?
(need to identify the value of access key for the particular row)

<SortedDescendingCellStyle BackColor="#E9EBEF" />
<SortedDescendingHeaderStyle BackColor="#4870BE" />
</asp:GridView>

You are very close, just lack CommandArgument:
<asp:TemplateField>
<ItemTemplate>
<asp:Button ID="AcceptRequest" runat="server"
OnClick="AcceptRequest_Click" Text="Accept"
CommandName="AcceptRequestcmd"
CommandArgument="<%# Eval("request_no") %> />
</ItemTemplate>
</asp:TemplateField>
(assuming that request_no is the row identifier)
Then just
protected void GridView1_RowCommand(...)
{
switch ( e.CommandName )
{
case "AcceptRequestcmd" :
string rowid = e.CommandArgument;
}
}
