I am using gridview in a page of website that I am builing with asp.net so I am using sqldatasource component to fill gridview.now I insert new data into the table and page is refreshed but new data is not displayed in the gridview how to solve this problem
Bind your gridview again after inserting new data. It will take time but you have to fetch the data from database and bind it again to gridview.
Gridview.DataSource = yourDataSource;
Gridview.DataBind();
Bind the Grid in page_Init()
It bind the data from your database Every page init

I made a gridview table for Projects which has values ProjectName, ClientID, ProjectLeader, StartDate and all the employees that work on that Project. Since i cant fit all the employees that work on a single project inside a small table i made a button inside that column that redirects you to another page where you can see table with all the employees. The employees are in another table in sql and i made third table which connects Projects and employees and it only contains ProjectID and EmployeeID. I have a button inside every row but i cant find a way how to make in code behind so that it takes the id of that project and prints on another page only employees that are working on that project.
public partial class Project : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void EmployeesOpen_Click(object sender, EventArgs e)
{
Response.Redirect("Employees_On_Project.aspx");
}
}

so I am learning ASP.NET currently and actually today is my second day.
So right now I am wanting to create a page where I have first a dynamically generated dropdown that selects just the first name from my database and table. This I have working
Next I have a gridview table that shows all the data from the database, currently I have hard coded a name so the page will not crash (there are 100000 rows of data)
Lastly when I post my code you will see a checkbox, that is just so when I click it the gridview will show up. I am just trying that out, because that was part of a lesson I learned today.

Here is my C# part where i call the session
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class Demos_GridView : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string name = DropDownList1.SelectedValue;
Session["FName"] = name;
}
protected void checkbox1_CheckedChanged(object sender, EventArgs e)
{
Panel1.Visible = CheckBox1.Checked;
}
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
}
}
As you see I called the session "I believe" I tried using this
<%:Session["user"]%>
within that sql query but it was saying I could not have the <%%> within the asp sql calling.
So if anyone could help me out that would be amazing.
Perhaps you should add the name of the user as a SqlParameter?
SqlDataSource1.SelectParameters.Add(new SqlParameter("#Name", name));
// Of course don't forget to edit your query: WHERE [FirstName] = #Name
Something as the above should work (note I haven't tested it).
Edit:
You could shorten this process even more by configuring your SqlDataSource to set the #Name parameter's value from a Control or Session.
I am trying to make my gridview update a SQL record but it is not updating the values.
Here is the aspx code:

</asp:GridView>
And the update function itself.
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
string s = GridView1.DataKeys[e.RowIndex].Value.ToString();
Label RID = GridView1.Rows[e.RowIndex].FindControl("RID") as Label;
TextBox SHORT_DESCRIPTION = GridView1.Rows[e.RowIndex].FindControl("SHORT_DESCRIPTION") as TextBox;
TextBox DESCRIPTION = GridView1.Rows[e.RowIndex].FindControl("DESCRIPTION") as TextBox;
String UpdateQuery = string.Format("UPDATE TAXONOMIES SET SHORT_DESCRIPTION='{0}', DESCRIPTION='{1}' WHERE RID = {2}", SHORT_DESCRIPTION.Text, DESCRIPTION.Text, Convert.ToInt32(RID.Text));
GridView1.EditIndex = -1;
BindGridData(UpdateQuery);
}
If I put a breakpoint and look at the value, I can see that is is not the newly typed in value. I'm not sure what is going on.
I think the problem is you are binding you grid on the page-load event.
try binding it in if (!IsPostBack)
Example
private void Page_Load()
{
if (!IsPostBack)
{
//bind your grid here.
}
}
use this code
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataKeyNames="id" DataSourceID="SqlDataSource1">
<Columns>
<asp:CommandField ShowEditButton="True" />
<asp:BoundField DataField="id" HeaderText="id" ReadOnly="True"
SortExpression="id" />
<asp:BoundField DataField="regGroupID" HeaderText="regGroupID"
SortExpression="regGroupID" />
<asp:BoundField DataField="amountReceived" HeaderText="amountReceived"
SortExpression="amountReceived" />
<asp:BoundField DataField="other" HeaderText="other" SortExpression="other" />
</Columns>
</asp:GridView>
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT * FROM [Table]"
UpdateCommand="UPDATE [Table] SET [regGroupID] = #regGroupID, [amountReceived] = #amountReceived, [other] = #other WHERE [id] = #id">
<DeleteParameters>
<asp:Parameter Name="id" Type="Int32" />
</DeleteParameters>
<UpdateParameters>
<asp:Parameter Name="regGroupID" Type="Int32" />
<asp:Parameter Name="amountReceived" Type="Decimal" />
<asp:Parameter Name="other" Type="String" />
<asp:Parameter Name="id" Type="Int32" />
</UpdateParameters>
</asp:SqlDataSource>
here I set id as the primary key
table structure is
Try changing the Eval to Bind. Eval is read-only so you can't actually update the value.
I need to show a Master/Child data in a page and I have used multiple GridViews to achieve the same. So, I have created two GridViews (Parent & Child) and now I want to fire the Button click event (i.e. btnLock) from the child gridview control and do some DB operations.
