WPF checkbox as button in code behind - wpf-controls

I want my checkbox to be visible as button. Check-boxes are generated dynamically in code behind file using C#.
How can I do that?

private void loadItems()
{
SqlConnection con = new SqlConnection();
con.ConnectionString = "ConString";
con.Open();
SqlCommand cmd = new SqlCommand("Select ItemId,ItemName from ITEMS", con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
for (int i = 0; i < dt.Rows.Count; i++)
{
iid = (dt.Rows[i]["ItemId"]).ToString();
iname = dt.Rows[i]["ItemName"].ToString();
CheckBox btn = new CheckBox();
btn.Content = iname;
btn.Height = 20;
btn.Width = 150;
btn.Tag = iname;
//var2 = btn.Tag.ToString();
wrapItems.Children.Add(btn);
btn.Click += new RoutedEventHandler(CheckBoxChecked);
//btn.RaiseEvent(new RoutedEventArgs(Button.btnClick(sender,e)));
con.Close();
}

How to export SharePoint list data to excel using a timer job with custom coding?

I am new to SharePoint programming.
Can anyone tell me how I can export list data to Excel using a timer job with some custom code?
Please go through the below link for creating timer jobs in sharepoint.
This article is contain the detailed process.
https://www.mssqltips.com/sqlservertip/3801/custom-sharepoint-timer-job/
The below code will help you to export the list data.
public void Export(List<int> ids)
{
DataTable table = new DataTable();
try
{
SPSite site = SPContext.Current.Site;
SPWeb web = SPContext.Current.Web;
SPSecurity.RunWithElevatedPrivileges(delegate()
{
using (SPSite siteE = new SPSite(site.ID))
{
using (SPWeb webE = siteE.OpenWeb(web.ID))
{
webE.AllowUnsafeUpdates = true;
SPList list = webE.Lists["Stationery"];
table.Columns.Add("Product", typeof(string));
table.Columns.Add("Quantity", typeof(Decimal));
DataRow newRow;
GridView gv = new GridView();
foreach (SPListItem item in list.Items)
{
if (ids.Contains(Convert.ToInt32(item["ID"].ToString())) && (item["Status"].ToString() == "New"))
{
newRow = table.Rows.Add();
newRow["Product"] = item["Product"].ToString();
newRow["Quantity"] = Convert.ToDecimal(item["Quantity"].ToString());
item["Status"] = "Exported";
item.Update();
}
}
SPBoundField boundField = new SPBoundField();
boundField.HeaderText = "Product";
boundField.DataField = "Product";
gv.Columns.Add(boundField);
boundField = new SPBoundField();
boundField.HeaderText = "Quantity";
boundField.DataField = "Quantity";
boundField.ControlStyle.Width = new Unit(120);
gv.Columns.Add(boundField);
gv.AutoGenerateColumns = false;
gv.DataSource = table.DefaultView;
gv.DataBind();
gv.AllowSorting = false;
HttpContext.Current.Response.ClearContent();
HttpContext.Current.Response.ClearHeaders();
string attachment = "attachment; filename=export" + "_" + DateTime.Now.ToShortTimeString() + ".xls";
HttpContext.Current.Response.AddHeader("content-disposition", attachment);
HttpContext.Current.Response.ContentType = "application/Excel";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
gv.RenderControl(htw);
HttpContext.Current.Response.Write(sw.ToString());
HttpContext.Current.Response.Flush();
HttpContext.Current.Response.Close();
HttpContext.Current.Response.End();
webE.AllowUnsafeUpdates = false;

invalid column name when my insert data is string,when i use int it works fine

When i replace EmerPacienti with PatientId it works fine, why happen that?
if (DropDownList3.SelectedItem.Value == "In-Pacient")
{
SqlDataAdapter Da = new SqlDataAdapter("select * from Ipacient where EmerPacienti=" + TextBox11.Text + "", cn);
//SqlCommandBuilder Cmd = new SqlCommandBuilder(Da);
DataSet Ds = new DataSet();
Da.Fill(Ds, "Ipacient");
GridView1.DataSource = Ds.Tables[0];
GridView1.DataBind();
Use sql parameters to prevent sql injection, then you also don't need to wrap it in apostrophes which is required on text columns. So this is much better:
using (var cn = new SqlConnection("insert connection string"))
using(var da = new SqlDataAdapter("select * from Ipacient where EmerPacienti=#EmerPacienti", cn))
{
da.SelectCommand.Parameters.Add("#EmerPacienti", SqlDbType.VarChar).Value = TextBox11.Text;
DataTable table = new DataTable();
da.Fill(table);
GridView1.DataSource = table;
GridView1.DataBind();
}
If it was an int-value use int.Parse/int.TryParse:
using (var cn = new SqlConnection("insert connection string"))
using(var da = new SqlDataAdapter("select * from Ipacient where PatientId=#PatientId", cn))
{
int patientId;
if (int.TryParse(TextBox11.Text, out patientId))
{
da.SelectCommand.Parameters.Add("#PatientId", SqlDbType.Int).Value = patientId;
// ...
}
}

Fill:selectcommand.connction property has not been initialised

i am getting error on sda.Fill(dt); that Fill:selectcommand.connction property has not been initialised what could be a problem in connection?
protected void Updatecustomer(object sender, GridViewUpdateEventArgs e)

finally

There is a post that can be found here that says that this is not possible.
However, the c# excel how to change a color of a particular row post on StackOverflow that provides code for changing a row colour... you may be able to adapt it for you purposes.

Add New Row in GridView winform on Button Click

Add New Row in GridView winform on Button Click.
Need to have single button in grid rather than DataGridViewButtonColumn
you can add it by using
GridView1.DataSource = datatable;
and then add new row by this
datatable.Rows.Add();
this will add new row and give control id into add().
use this
public partial class Form1 : Form
{
Button textBoxDgv1 = new Button();
Label labelDgv1 = new Label();
the next is on the Form_Load event
private void Form1_Load(object sender, EventArgs e)
{
labelDgv1.Text = "Delete";
labelDgv1.Height = 20;
labelDgv1.AutoSize = false;
labelDgv1.BorderStyle = BorderStyle.FixedSingle;
labelDgv1.TextAlign = ContentAlignment.MiddleCenter;
int Xdgv1 = this.dataGridView1.GetCellDisplayRectangle(2, -1, true).Location.X;
labelDgv1.Width = this.dataGridView1.Columns[2].Width + Xdgv1;
labelDgv1.Location = new Point(0, this.dataGridView1.Height - textBoxDgv1.Height);
this.dataGridView1.Controls.Add(labelDgv1);
and one more section is in dataGridView1_CellPainting
private void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
{
int sum = 0;
for (int i = 0; i < this.dataGridView1.Rows.Count; i++)
{
if (dataGridView1.Rows[i].Cells[3].Value != string.Empty)
{
sum += Convert.ToInt32(this.dataGridView1[3, i].Value);
}
}
textBoxDgv1.Text = sum.ToString();
int Xdgvx = this.dataGridView1.GetCellDisplayRectangle(2, -1, true).Location.X;
labelDgv1.Width = this.dataGridView1.Columns[2].Width + Xdgvx;
labelDgv1.Location = new Point(0, this.dataGridView1.Height - textBoxDgv1.Height);
textBoxDgv1.Width = this.dataGridView1.Columns[3].Width;
Xdgvx = this.dataGridView1.GetCellDisplayRectangle(3, -1, true).Location.X;
textBoxDgv1.Location = new Point(Xdgvx, this.dataGridView1.Height - textBoxDgv1.Height);
}
