i need that by default Gridview must have 10 empty rows with only one Column that column should have Textbox
here is my script of gridview
<asp:GridView ID="gv_Others" runat="server" AutoGenerateColumns="false"
onrowdatabound="gv_Others_RowDataBound"
onrowcreated="gv_Others_RowCreated">
<Columns>
<asp:TemplateField ItemStyle-Width="40px">
<ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />
<ItemTemplate>
<asp:TextBox ID="txtemp" runat="server"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
is that possible to create 10 empty rows by default in a gridview?
you can try this
string[] str = new string[10];
List lstStr = str.ToList<string>();
gv_Others.DataSource = lstStr ;
gv_Others.DataBind();
var list = new List<string>();
for (int i = 0; i < 10; i++)
{
list.Add(string.Empty);
}
gv_Others.DataSource = list;
gv_Others.DataBind();
This is the quickest and dirtiest way I could think of, would I write something like this? No. But then I'm sure you have your reasons, would have been better if you'd written in your question what you were trying to achieve then we could have helped more and your question wouldn't have got marked down.

I have created a program that runs through a flow using C#
At the moment it contains a large amount of buttons to make certain panels visible etc.
I was wondering if I could make the page refresh when the user checks a checkbox?
You need to set the CheckBox' AutoPostBack-property to true(default is false).
<asp:CheckBox id="checkbox1" runat="server"
AutoPostBack="True"
Text="Check/uncheck me for a postback"
OnCheckedChanged="Check_Clicked"/>
IF you want to refresh your panel on check of checkbox, you can do something like below:-
<asp:CheckBox id"chkVisible" runat="server" AutoPostBack="true" OnCheckedChanged="chkVisible_OnCheckedChanged" Text="Test for Page referesh" />
You need to set AutoPostBack property to True for refreshing your page.
Try this :
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
//do whatever you want to on first time page load
}
}

Can someone give an idea how I can see details of a selected product (suppose) regarding The productID in another page with HyperLink?? I have Tried To pass The ID with QueryString with Linq. But not done.
Mark up
<asp:HyperLink ID ="hyperLink" runat="server" />
C#
Set the url:
hyperLink.NavigateUrl = "somePage.aspx?id=123";
Read the url query string in somePage.aspx
var id = Request.QueryString["id"];
You have multiple problems in your code (as given in your comment section).
Here is what you have
<asp:HyperLink ID = "View" server = "runat" NavigateUrl = '<%# ("~/pageredirect.aspx") + eval("CatergoryID") %>'>View</asp:HyperLink>
Issues:
you have server = "runat" and it should be runat="server"
you are concatenating CatergoryID with the redirect page and not really passing as querystring which will really append the value like pageredirect.aspx + categoryid
you are binding as CatergoryID and retrieving by query string name CategoryID which is not same (notice the typo)
Change your asp:HyperLink definition in the itemtemplate of the gridview in Approve.aspx as below
<asp:TemplateField>
<ItemTemplate>
<asp:HyperLink ID="hlView" runat="server" NavigateUrl='<%# Eval("CategoryID", "~/pageredirect.aspx?CategoryID={0}") %>' Text="View" />
</ItemTemplate>
</asp:TemplateField>
and then in your pageredirect.aspx.cs access the querystring value as
if (!String.IsNullOrEmpty(Request.QueryString["CategoryID"]))
{
int m = Int32.Parse(Request.QueryString["CategoryID"]);
....
}

Mine checkboxlist is very ugly. the Box doesn't align properly. See the screenshot.
I would like to mention that your checkbox list will be stick to the Width="195px".
So suggestion from my side is either increase the width as per your design or remove it as mentioned below :
<asp:CheckBoxList runat="server" ID="cblType"
OnSelectedIndexChanged="cblType_OnSelectedIndexChanged" AutoPostBack="True"
RepeatDirection="Horizontal">
<Items>
<asp:ListItem Text="IPP Stories" Value="IPP Stories"></asp:ListItem>
<asp:ListItem Text="OutReach Activities " Value="OutReach Activities"></asp:ListItem>
<asp:ListItem Text="CCA" Value="CCA"></asp:ListItem>
<asp:ListItem Text="Community Work" Value="Community Work"></asp:ListItem>
<asp:ListItem Text="Competition" Value="Competition"></asp:ListItem>
<asp:ListItem Text="Overseas Experience" Value="Overseas Experience"></asp:ListItem>
<asp:ListItem Text="FYPJ" Value="FYPJ"></asp:ListItem>
</Items>
</asp:CheckBoxList>
Suggestion :
If I am facing this situation then I would make it in two rows by adding RepeatColumns="3" or RepeatColumns="4" in CheckboxList property.
I don't think you need to specify any width here, try not to and perhaps it will do the job. If not, please post the pertinent css style (if any)...
<asp:CheckBoxList runat="server" ID="cblType"
OnSelectedIndexChanged="cblType_OnSelectedIndexChanged" AutoPostBack="True"
RepeatDirection="Horizontal">

With a datatable that has a column as hyperlink, is it possible to select the whole row?
If so, how can we select and highlight so user can see the row is selected?
if you are talking about gridview try see about GridView.SelectedRowStyle Property
you can try it like this
<asp:gridview id="CustomersGridView"
...
autogenerateselectbutton="True"
selectedindex="1"
... >
<Columns>
...
</Columns>
<selectedrowstyle backcolor="LightCyan"
forecolor="DarkBlue"
font-bold="true"/>
</asp:gridview>
or if you have special css class for selected row
<asp:gridview id="CustomersGridView"
...
autogenerateselectbutton="True"
selectedindex="1"
... >
<Columns>
...
</Columns>
<selectedrowstyle CssClass="YouCssClassForSelectedRow"/>
</asp:gridview>
