I have one repeater which displays the list of puja.i have also used one datalist to display the names of temples.whenever i click on search it displays only the last value of the repeater i.e it is taking only the last value of the repeater....my question is how to use loop inside a repeater???
here is my code behind how i used datalist and repeater:
protected void Page_Load(object sender, EventArgs e)
{
//lblnodatafound.Visible = true;
//lbldatafound.Visible = false;
if (Request.QueryString["search"] != null)
{
var dt = new DataTable("Data");
String source = Request.QueryString["search"];
var splitseparator = new string[] { " " };
String[] result = source.Split(splitseparator, StringSplitOptions.RemoveEmptyEntries);
foreach (String s in result)
{
if (IsAlphaNumeric(s) == true)
{
var dttemp = new DataTable();
dttemp = fnsearch(s);
dt.Merge(dttemp, true);
}
}
if (dt.Rows.Count != 0)
{
int count = dt.Rows.Count;
if (dt.Rows.Count > 0)
{
DataList1.DataSource = dt;
DataList1.DataBind();
lblnodatafound.Visible = false;
lbldatafound.Visible = true;
//added the repeater to display the list of puja
for (int i = 0; i < dt.Rows.Count; i++)
{
String id = dt.Rows[i]["id"].ToString();
string query = "select puja.id,puja.name as puja_name, mandir.name as mandir_name from puja,mandir where mandir.id= puja.with_mandir and puja.with_mandir = '" + id + "'";
conn.Open();
MySqlCommand cmd = new MySqlCommand(query, conn);
MySqlDataAdapter adp = new MySqlDataAdapter(cmd);
DataTable dt1 = new DataTable();
adp.Fill(dt1);
conn.Close();
if (dt1.Rows.Count > 0)
{
lblmandirpuja.Text = "Poja in " + dt1.Rows[0]["mandir_name"];
foreach (RepeaterItem repeatItem in Repeater1.Items){
Repeater1.DataSource = dt1;
Repeater1.DataBind();
}
}
}
}
}
else
{
lblnodatafound.Visible = true;
lbldatafound.Visible=false;
}
}
}
Try to change this line:
if (dt1.Rows.Count > 0)
for something like:
for(int i = 0; i < dt1.Rows.Count; i++)
And this one:
lblmandirpuja.Text = "Poja in " + dt1.Rows[0]["mandir_name"];
The 0 for the i:
lblmandirpuja.Text = "Poja in " + dt1.Rows[i]["mandir_name"];

How to Add key press in ' if(count<= 3)' condition. in this code we have define that if the input length is less than 3 or equal to 3 consider the input as quantity and then again go for the input if the input length is greater than 3 then consider the input as item code and search from database and quantity that we have entered it first time.

I have 3 listboxes.The listbox fetches two values by code-datatextfield and datavaluefield. 1st listbox transfers the datatextfield items from 1st listbox to 2nd listbox.i want to transfer the datavaluefield of selected 1st listbox items to 3rd listbox.
if (ListBox3.SelectedIndex >= 0
{
for (int i = 0; i < ListBox3.Items.Count; i++)
{
if (ListBox3.Items[i].Selected)
{
if (!arraylist1.Contains(ListBox3.Items[i]))
{
arraylist1.Add(ListBox3.Items[i]);
Session["value"] = ListBox3.Items[i];
}
}
}
for (int i = 0; i < arraylist1.Count; i++)
{
if (!ListBox2.Items.Contains(((ListItem)arraylist1[i])))
{
ListBox2.Items.Add(((ListItem)arraylist1[i]));
}
ListBox3.Items.Remove(((ListItem)arraylist1[i]));
}
ListBox2.SelectedIndex = -1;
}
else
{
}
SqlConnection con = new SqlConnection(strcon);
SqlCommand command = new SqlCommand("select * from IT_1_BOILER_DESK_1_PARAMETERS where paramtext='" + Session["value"] + "'", con);
SqlDataAdapter dataAadpter = new SqlDataAdapter(command);
DataSet ds = new DataSet();
dataAadpter.Fill(ds);
if (ds != null)
{
ListBox1.DataSource = ds.Tables[0];
ListBox1.DataTextField = "param";
//ListBox3.DataValueField = "param";
ListBox1.DataBind();
}
for listbox 3
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection(strcon);
SqlCommand command = new SqlCommand("select * from IT_1_BOILER_DESK_1_PARAMETERS where pname='" + this.DropDownList1.SelectedValue + "'" ,con);
SqlDataAdapter dataAadpter = new SqlDataAdapter(command);
DataSet ds = new DataSet();
dataAadpter.Fill(ds);
if (ds != null)
{
ListBox3.DataSource = ds.Tables[0];
ListBox3.DataTextField = "paramtext";
ListBox3.DataValueField = "param";
ListBox3.DataBind();
}
}
But i want to display the datavaluefield of the items that are selected from listbox3 to listbox1
Since you want to show DataTextField value and DataValueField value from one listbox into 2 different listbox. I suggest you to use a different approach. This will also reduce usage of 2nd database call.
Try following:-
if (ListBox3.SelectedIndex >= 0)
{
for (int i = 0; i < ListBox3.Items.Count; i++)
{
if (ListBox3.Items[i].Selected)
{
if (!arraylist1.Contains(ListBox3.Items[i]))
{
arraylist1.Add(ListBox3.Items[i]);
//Session["value"] = ListBox3.Items[i]; no need of this
}
}
}
for (int i = 0; i < arraylist1.Count; i++)
{
if (ListBox2.Items.FindByText(((ListItem)arraylist1[i]).Text)==null)
{
//since you already have text and value field values in arrayList. Use them
ListBox2.Items.Add(new ListItem(((ListItem)arraylist1[i]).Text));
}
if (ListBox1.Items.FindByText(((ListItem)arraylist1[i]).Text)==null)
{
ListBox1.Items.Add(new ListItem((ListItem)arraylist1[i]).Value));
}
ListBox3.Items.Remove(((ListItem)arraylist1[i]));
}
ListBox2.SelectedIndex = -1;
}
else
{
}
/* This database call can be removed
SqlConnection con = new SqlConnection(strcon);
SqlCommand command = new SqlCommand("select * from IT_1_BOILER_DESK_1_PARAMETERS where paramtext='" + Session["value"] + "'", con);
SqlDataAdapter dataAadpter = new SqlDataAdapter(command);
DataSet ds = new DataSet();
dataAadpter.Fill(ds);
if (ds != null)
{
ListBox1.DataSource = ds.Tables[0];
ListBox1.DataTextField = "param";
//ListBox3.DataValueField = "param";
ListBox1.DataBind();

I have a listbox in my webform from which I am trying to select multiple values, but I am only getting last selected values. I have tried in two ways. First I explicitly added list items:
<asp:ListBox ID="ListBox2" runat="server"
SelectionMode="Multiple" AutoPostBack="True">
<asp:ListItem>teama</asp:ListItem>
<asp:ListItem>teamb</asp:ListItem>
</asp:ListBox>
Second, I tried to bind to a table in a database:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
ListBox2.SelectionMode = ListSelectionMode.Multiple;
string scon = ConfigurationManager.ConnectionStrings["Test_AthiraConnectionString"].ConnectionString;
SqlConnection con=new SqlConnection(scon);
con.Open();
SqlCommand cmd = new SqlCommand("select department from department", con);
cmd.CommandType = CommandType.Text;
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
ListBox2.DataSource = ds;
ListBox2.DataValueField = "department";
ListBox2.DataTextField = "department";
ListBox2.DataBind();
con.Close();
}
}
Then I tried these different methods to select multiple items on buttonclick event
First:
string k =null ,k1 = null;
foreach (int i in ListBox2.GetSelectedIndices())
{
k1 = ListBox2.Items[i].Text + "/";
k += k1;
Response.Write(k);
}
Second:
foreach (ListItem li in ListBox2.Items)
{
if (li.Selected == true)
{
k += li.Text + "/";
Response.Write(k);
}
}
Third:
k = String.Join("/", ListBox2.Items
.Cast<ListItem>()
.Where(i => i.Selected)
.Select(i=>i.Value)
.ToArray());
Response.Write(k);
Fourth:
for (int i = ListBox2.Items.Count - 1; i >= 0; i--)
{
if (ListBox2.Items[i].Selected == true)
{
k1 = ListBox2.Items[i].Text + "/";
k += k1;
Response.Write(k);
}
}
But none of them seem to work. I am getting only the last selected value.
You may access the items in the list as follow and check their properties.
IEnumerator ie = ListBox2.Items.GetEnumerator();
while (ie.MoveNext())
{
ListItem li = (ListItem)ie.Current;
//Use ListItem here
}
please try below code, It will return coma separator string for Listbox selected value
public string GetSelectedValues()
{
string selectedVal = string.Empty;
int i = 0;
foreach (int index in lstbox.GetSelectedIndices())
{
if (i == 0)
selectedVal = lstbox.Items[index].Value;
else
selectedVal = selectedVal + ";" + lstbox.Items[index].Value.ToString();
i++;
}
return selectedVal ;
}
I have the following code snippet:
if (!IsPostBack)
{
if (Request.QueryString["id"] != null)
{
string catid = Request.QueryString["id"].ToString();
Query1 = "select senderfirstname from messages where senderid='" + catid + "'";
adap = new SqlDataAdapter(Query1, con);
DataTable dt = ds.Tables["messages"];
DataRow dr = dt.Rows[0];
if (dt.Rows.Count > 0)
{
Session["table"] = dr["senderfirstname"].ToString();
}
else
{
Label1.Text = "error";
}
}
}
But I'm getting an error as:
There is no row at position 0.
I have the same query in sql server, but my table has contents for this query.
You are not loading data in to the DataSet. You have to call SqlDataAdapter.Fill to load the data in the DataSet. Also assign the row in the condition where you check that Rows count is greater then zero for not getting exception when not row exists.
if (!IsPostBack)
{
if (Request.QueryString["id"] != null)
{
string catid = Request.QueryString["id"].ToString();
Query1 = "select senderfirstname from messages where senderid='" + catid + "'";
adap = new SqlDataAdapter(Query1, con);
adap.Fill(ds);
DataTable dt = ds.Tables["messages"];
if (dt.Rows.Count > 0)
{
DataRow dr = dt.Rows[0];
Session["table"] = dr["senderfirstname"].ToString();
}
else
{
Label1.Text = "error";
}
}
}
Please check your updated code below
if (!IsPostBack)
{
if (Request.QueryString["id"] != null)
{
string catid = Request.QueryString["id"].ToString();
Query1 = "select senderfirstname from messages where senderid='" + catid + "'";
adap = new SqlDataAdapter(Query1, con);
DataTable dt = ds.Tables["messages"];
if (dt.Rows.Count > 0)
{
DataRow dr = dt.Rows[0];
Session["table"] = dr["senderfirstname"].ToString();
}
else
{
Label1.Text = "error";
}
}
