Get Gridview Datakey from nested gridview

I've got a gridview nested inside another gridview. What I need is that on the inner gridview get the DataKey from the outer gridview.
How can I pass it?
Thanks.
UPDATE
<asp:GridView ID="gvPeople" runat="server" AutoGenerateColumns="false" CssClass="Grid" DataKeyNames="person_id" OnRowDataBound="gvPeople_RowDataBound">
<Columns>
<asp:TemplateField HeaderStyle-Width="10px" ItemStyle-HorizontalAlign="Center">

<asp:BoundField ItemStyle-Width="150px" DataField="total_cost" HeaderText="Total Cost" DataFormatString="{0:#,#0.00 €}" />
</Columns>
</asp:GridView>
Here is my aspx code, which is all working, with the excpetion of the new document button, which runs a javascript button, as the edit button, but on this one I need to pass the person_id, from the row of the gvPeople, so when I create a new gvDocuments row, it will make it to that person id.
Thanks.

Just put it to work.
Add a hiddenfield before the child gridview with the value that I want.
On the RowDataBound of the child gridview, added this:
string str= ((HiddenField)e.Row.Parent.Parent.Parent.FindControl("hf")).Value.ToString();
And now use the str value for anything that I want.

You need to first access each of the parent gridview row then access the child gridview row then access the datakey.
Example:
foreach (GridViewRow rowPeople in gvPeople.Rows)
{
GridView gvDocuments = (GridView)rowPeople.FindControl("gvDocuments");
//this will get you the outer/parent gridview datakeys
gvDocuments.DataKeys[rowPeople.RowIndex].Values[0].ToString();
foreach (GridViewRow rowDocuments in gvDocuments.Rows)
{
//this will get you the inner/child gridview datakeys
gvDocuments.DataKeys[rowDocuments.RowIndex].Values[0].ToString();
}
}
Let me know if that works for you!

How to set gridview template fields in right side?

I have a gridview with template fields.Now all template fields are showing in the left side of gridview. How can I set it to the right side? My gridview is
<asp:GridView ID="GridView1" BorderWidth="1px" CellSpacing="18" CellPadding="10" runat="server">
<Columns >
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="LinkButton4" runat="server">Single OT</asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="LinkButton4" runat="server">Double OT</asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
And also binding a query with this gridview. My Query is
qry="select OT from OverTime where EmpCode=#EmpCode"
dr=conn.query(qry);
GridView1.DataSource = dr;
GridView1.DataBind();

Youcan use the ItemStyle-HorizontalAlign attribute:
<asp:TemplateField ItemStyle-HorizontalAlign="Right">

For particular Template Column you can add ItemStyle tag like,
<asp:TemplateColumn>
<ItemStyle HorizontalAlign="Right" Width="150px"></ItemStyle>
</asp:TemplateColumn>
so that the content within that particular Template Column gets aligned towards right
Hope this helps!!

How to select a cell in datagrid onClick in ASP.net C#

I am importing a column in datatable to my grid. Now I want navigate to a new page on selecting a cell in grid by fetching the selected value. I have tried this by including bound field in my grid like
<asp:GridView ID="GDV_1" runat="server" EnableModelValidation="true" AutoGenerateColumns="false" OnSelectedIndexChanged="GDV_1_SelectedIndexChanged" AutoGenerateSelectButton="false" DataKeyNames="SROID">
<Columns>
<asp:BoundField DataField="SRONameinEnglish" HtmlEncode="False" DataFormatString="<a target='_blank' href='Test.aspx?code={0}>ClickHere</a>" />
</Columns>
</asp:GridView>
Doing this way my requirement is achieved but the all cells are displaying Common text Click here instead of showing data from Database.
Please give your suggestion on how to get the value from database into cell and make it clickable. I don't want to use Select button. Please find my current output.
This is my current output I want my data from DB instead of ClickHere.

You can use TemplateField
<asp:TemplateField HeaderText="Name">
<ItemTemplate>
<asp:LinkButton runat="server" ID="lnk<%# Eval("SRONameinEnglish")%>"><%# Eval("SRONameinEnglish")%></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
and click of LinkButton put your code to navigate anywhere.

In your case you are binding boundfield with static a tag which have href attribute so your not able to change text on that boundfield from your database.To get your approach you should
use TemplateField and bind data with text attribute using eval keyword as below example.
Try it:
<asp:TemplateField HeaderText="Name">
<ItemTemplate>
<asp:HyperLink ID="HyperLink1" runat="server" Text='<%# Eval("name") %>' />
</ItemTemplate>
</asp:TemplateField>
OR
you can also bind link with your hyperlink using NavigateUrl property of hyperlink as below example.
<asp:TemplateField HeaderText="Name">
<ItemTemplate>
<asp:HyperLink id="HyperLink2" NavigateUrl='<%#Eval("YourUrl") %>' Text='<%#Eval("name") %>' runat="server"/>
</ItemTemplate>
</asp:TemplateField>
I hope it will helpful to you.

How to define number of rows of GridView at runtime in code behind using C#

I need to develop such a program in which the GridView's rows should be decided at run time.
i.e. I have a table in database called dealer capacity.
Dealer_ID Capacity
D0001 5
Now when the Dealer D00001 is selected from combo box the number of rows in grid view should be 5. I want to use the template field also.
My code for GridView is:
<asp:GridView ID="grdlicence" runat="server" DataKeyNames="Version_id" GridLines="None" BorderStyle="Solid" AutoGenerateColumns="false" AllowSorting="true"
CssClass="mGrid table"
PagerStyle-CssClass="pgr"
AlternatingRowStyle-CssClass="alt" >
<Columns>
<asp:BoundField DataField="Version_name" ItemStyle-CssClass="uppercase" ItemStyle-Width="150px" HeaderText="Version" HeaderStyle-HorizontalAlign="Left" />
<asp:BoundField DataField="Version_id" Visible="false" HeaderText="Version" HeaderStyle-HorizontalAlign="Left" />
<asp:TemplateField HeaderText="Price">
<ItemTemplate>
<center><asp:TextBox ID="txtprice" CssClass="alignments TextStyle" MaxLength="5" runat="server" ></asp:TextBox></center>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Licence Id">
<ItemTemplate>
<center><asp:TextBox ID="txtlicenceid" CssClass="alignments uppercase" runat="server" ></asp:TextBox></center>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Purchase Date">
<ItemTemplate>
<center><asp:TextBox ID="txtpurchasedate" onfocus="showCalendarControl(this);" CssClass="alignments TextStyle" runat="server"></asp:TextBox></center>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Expiry Date">
<ItemTemplate>
<center><asp:TextBox ID="txtexpirydate" onfocus="showCalendarControl(this);" CssClass="alignments TextStyle" runat="server"></asp:TextBox></center>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Upload File">
<ItemTemplate>
<center><asp:FileUpload ID="fileUpload" runat="server" /></center>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

You need to define PageSize for your GridView and remember to set AllowPaging to true for the GridView
GridView.PageSize Property
Gets or sets the number of records to display on a page in a GridView
control.
The default is 10.
You may see this article: GridView Paging Sample in ASP.NET

You can use the linq Take() and pass the number as parameter.
Updated according to the comment, use following code.
grdlicence.DataSourse= ds.Take(5);
grdlicence.DataBind();

Conditional HyperLink in GridView?

I have a gridview with a hyperlink:
<asp:GridView ID="gvEmployees" runat="server" AutoGenerateColumns="False"
CssClass="table table-hover table-striped" GridLines="None" >
<Columns>
<asp:TemplateField HeaderText="Name" SortExpression="EmployeName">
<ItemTemplate>
<asp:HyperLink ID="HyperLink1" runat="server"
Text='<%# Bind("EmployeName") %>' ></asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="ID" SortExpression="EmployeID" Visible="False">
<ItemTemplate>
<asp:Label ID="lblID" runat="server" Text='<%# Bind("EmployeID") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
However, it should only appear as a hyperlink if the employeeID is that of the logged in employee.
I can do all that, but what I do not know is how to make the hyperlink look like a Label. It's easy to have it not link anywhere, but I do not know how to make it look like a label.
Thanks

I believe if you set Enabled="false" it does. If it does not, then the only way to do that is put both a HyperLink and Label in the cell, and show the link when appropriate, and the label when appropriate, hiding the other one (which can be easily done in RowDataBound event).
