I have a problem with the collectionpager and repeater. When I load the page, collectionpager is working fine.. But when I click the search button and bind new data, clicking the page 2 link, it is firing the page_load event handler and bring all the data back again... Notice: All controls are in an UpdatePanel.

the code is very bad and you should completely review all of it.
the issue is every time the page load is executed it initializes again you query to the default one (the one with not filter) you should find a way to store somewhere the last query has been execute when you order/filtering your data.
Anyway the are lot of example on the web showing what you are trying to achieve
the below is just one of them

try this EnableViewState="false"
You have to bind the CollectionPager again on your search.

My update button is not functioning. Whenever I want to update any record, it will not works.
Radio button must be checked in order to update any records in a gridview. After the button is checked, the user will click an update button (located above the gridview). then a page will be displayed. the page will display all the information (in a form view) of the user. he/ she will just change any information they want. after that the user should click update button located below. It is like submitting the form again. But the form is not updated. What should i change?
Below is the code for update button:
protected void update_Click(object sender, EventArgs e)
{
if (Page.IsValid)
{
string datestart_s = (string)(Session["datestart"]);
datestart_s = Convert.ToDateTime(datestart_s).ToString("yyyy-MM-dd");
string leavetype_c = (string)(Session["leavetype"]);
string X = TextBox3.Text;
string substring1 = X;
string substring2 = "";
foreach (string value in X.Split('-'))
if (X.Length > 40)
{
substring1 = X.Substring(0, 40);
if (X.Length == 80)
{
substring2 = X.Substring(39, 40);
}
else
{
int Xlength = X.Length - 40;
substring2 = X.Substring(40, Xlength);
}
}
OdbcConnection connection = null;
OdbcCommand com = null;
string queryString = "UPDATE QMBSTEST.SCEMLV SET LVTYPE='" + leave.SelectedItem.Value + "', LVDTST='" + start.Text + "', LVDTED='" + end.Text + "', LVDAYS='" + TextBox2.Text + "', LVAMPM='" + time.SelectedItem.Value + "', LVTEXT1='" + substring1 + "', LVTEXT2='" + substring2 + "', LVFLAG='" + apply.SelectedItem.Value + "' WHERE LVEMID='" + TB_EMPID.Text.Trim().ToUpper() + "' AND LVDTST='" + datestart_s.Trim() + "' AND LVTYPE='" + leavetype_c.Trim() + "'";
connection = new OdbcConnection(#"Dsn=as400;Uid=FATIN;Pwd=FATIN;");
com = new OdbcCommand(queryString, connection);
connection.Open();
com.ExecuteNonQuery();
connection.Close();
lblMessage.Text = "Form updated!";
lblMessage.ForeColor = System.Drawing.Color.GreenYellow;
}
}
Are you validating that event with any customvalidator?
If yes then replace :
if (Page.IsValid)
With
IF(!IsValild)
return:
and then ur code.....
Because you not doing anything when any of your validation through validation control got failed.
I want to update multi checkboxlist value to the the database. I already databound my checkboxlist from other table which is the medicine table. Now i want to update my value to consultation table, but i can not
`
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
try
{
for (int i = 0; i < txtcheckbox.Items.Count - 1; i++)
{
if (txtcheckbox.Items[i].Selected == true)
{
str = str + txtcheckbox.Items[i].Text + ",";
}
}
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);
String sql = "UPDATE [consultation] set mname3 = " + str + " WHERE [conid] = #conid";
con.Open();
SqlCommand cmd = new SqlCommand(sql, con);
cmd.Parameters.AddWithValue("#conid", txtconid);
cmd.Parameters.AddWithValue("#mname3", str);
int j = cmd.ExecuteNonQuery();
if (j > 0)
{
Label2.Visible = true;
Label2.Text = "Successfully Complete Dispensary";
txtconid.Text = "";
}
else
{
Label2.Visible = true;
Label2.Text = "Not Successfully Complete Dispensary";
txtconid.Text = "";
}
con.Close();
}
catch
{
Label2.Visible = true;
Label2.Text = "Error";
txtconid.Text = "";
}
}
`
I guess you have exception here. Because:
String sql = "UPDATE [consultation] set mname3 = " + str + " WHERE [conid] = #conid";
here you use concatenation of strings and your sql query will look like:
UPDATE [consultation] set mname3 = sometextvale WHERE [conid] = #conid
mname3 have nvarchar sql type I guess, so you need to put string value in qoutes:
String sql = "UPDATE [consultation] set mname3 = ' " + str + " ' WHERE [conid] = #conid";
Or you can use paramaeter for sql query, like you already did for #conid:
String sql = "UPDATE [consultation] set mname3 = #mname3 WHERE [conid] = #conid";
It's better solution in security way.
Some additional comments:
for (int i = 0; i < txtcheckbox.Items.Count - 1; i++)
Are you sure here should be txtcheckbox.Items.Count - 1? You will lost the last one.
And the 2nd one: Mix code for construction and execution query (DAL) in code behind of page with some kind of business logic not a good practice =)
I am trying to collect data from a form using asp.net and insert it into a sql view that is made up of multiple tables. however an error keeps being displayed saying 'v_orderdetails is not updatable because the modification affects multiple base tables.' Can anybody help, below is my code:
public partial class _Order : System.Web.UI.Page
{
string myConnectionString;
protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack)
{
}
}
protected void Orderbtn_Click(object sender, EventArgs e)
{
SqlConnection myConn = new SqlConnection();
myConnectionString = "server=CSSQL; database=Oh31_PE; Trusted_Connection = true";
myConn.ConnectionString = myConnectionString;
string querystring1;
querystring1 = "insert into v_orderdetails (dbo.t_order.OrderDate, dbo.t_product.Material, dbo.t_product.Description, dbo.t_orderdetails.Quantity) values ( '";
querystring1 += od.Text + "','" + opname.Text + "','" + tom.Text + "','" + tod.Text + "','" + qq.Text + "')";
SqlCommand dbcommand1 = new SqlCommand();
dbcommand1.CommandText = querystring1;
dbcommand1.Connection = myConn;
myConn.Open();
dbcommand1.ExecuteNonQuery();
myConn.Close();
{
Response.Redirect("Order.aspx");

}

Note:1- in aspx :CommandArgument='<%#((GridViewRow)Container).RowIndex%>'
2- use RowCommand event for the grid view.
