I have an application in which I have an upload image page where I upload images and store those images in different folders under image folder and its path in a database. The flow of that goes like this:
user selects file from the system
user add description
user selects department from the drop-down list and according to that selection the image is stored in a different department's folder.
this is my uploadImage.cs page code:
In this page first we check that we have folder under Image/Department folder or not if not than we create folder and store image under that department else if already create that store image under that department
protected void btnSubmit_Click1(object sender, EventArgs e)
{
con.ConnectionString = System.Configuration.ConfigurationManager.ConnectionStrings["WebGallery"].ConnectionString;
string Description = tbImageName.Text.Trim();
string Priority = lblPriority.Text.Trim();
string imgName = fileuploadimages.FileName.ToString();
string imgPath = "Images/Departments/" + "" + ddlDepartment.SelectedValue + "/";
bool IsExists = System.IO.Directory.Exists(Server.MapPath(imgPath));
if (!IsExists)
System.IO.Directory.CreateDirectory(Server.MapPath(imgPath));
fileuploadimages.SaveAs(Server.MapPath(imgPath + imgName));
con.Open();
SqlCommand cmd = new SqlCommand("insert into Images(ImageName, Description, Path, Priority) values (@ImageName, @Description, @Path, @Priority)", con);
cmd.Parameters.AddWithValue("@ImageName", imgName);
cmd.Parameters.AddWithValue("@Description", Description);
cmd.Parameters.AddWithValue("@Path", imgPath + imgName);
cmd.Parameters.AddWithValue("@Priority", lblPriority.Text);
cmd.ExecuteNonQuery();
con.Close();
tbImageName.Text = string.Empty;
}
In this page we create,edit,update and delete department. Now when user click on delete button i want to delete that folder so that all the image under that folder will also delete.
My departmentMaste.cs page code:
protected void BindEmployeeDetails()
{
con.Open();
SqlCommand cmd = new SqlCommand("Select * from Department_Master", con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
con.Close();
if (ds.Tables[0].Rows.Count > 0)
{
gvDetails.DataSource = ds;
gvDetails.DataBind();
}
else
{
ds.Tables[0].Rows.Add(ds.Tables[0].NewRow());
gvDetails.DataSource = ds;
gvDetails.DataBind();
int columncount = gvDetails.Rows[0].Cells.Count;
gvDetails.Rows[0].Cells.Clear();
gvDetails.Rows[0].Cells.Add(new TableCell());
gvDetails.Rows[0].Cells[0].ColumnSpan = columncount;
gvDetails.Rows[0].Cells[0].Text = "No Records Found";
}
}
protected void gvDetails_RowEditing(object sender, GridViewEditEventArgs e)
{
gvDetails.EditIndex = e.NewEditIndex;
BindEmployeeDetails();
}
protected void gvDetails_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
string id = gvDetails.DataKeys[e.RowIndex].Values["ID"].ToString();
TextBox txtDepartment = (TextBox)gvDetails.Rows[e.RowIndex].FindControl("txtDepartment");
con.Open();
SqlCommand cmd = new SqlCommand("update Department_Master set DepartmentName='" + txtDepartment.Text + "'where ID=" + id, con);
cmd.ExecuteNonQuery();
con.Close();
lblresult.ForeColor = Color.Green;
lblresult.Text = id + " Details Updated successfully";
gvDetails.EditIndex = -1;
BindEmployeeDetails();
}
protected void gvDetails_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
{
gvDetails.EditIndex = -1;
BindEmployeeDetails();
}
protected void gvDetails_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
string id = gvDetails.DataKeys[e.RowIndex].Values["ID"].ToString();
con.Open();
SqlCommand cmd = new SqlCommand("delete from Department_Master where ID=" + id, con);
int result = cmd.ExecuteNonQuery();
con.Close();
if (result == 1)
{
BindEmployeeDetails();
lblresult.ForeColor = Color.Red;
lblresult.Text = id + " details deleted successfully";
}
}
protected void gvDetails_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
string id = Convert.ToString(DataBinder.Eval(e.Row.DataItem, "ID"));
ImageButton lnkbtnresult = (ImageButton)e.Row.FindControl("imgbtnDelete");
if (lnkbtnresult != null)
{
lnkbtnresult.Attributes.Add("onclick", "javascript:return ConfirmationBox('" + id + "')");
}
}
}
protected void gvDetails_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName.Equals("AddNew"))
{
TextBox txtDepartment = (TextBox)gvDetails.FooterRow.FindControl("txtDepartment");
con.Open();
SqlCommand cmd =
new SqlCommand("insert into Department_Master values('" + txtDepartment.Text + "')", con);
int result = cmd.ExecuteNonQuery();
con.Close();
if (result == 1)
{
BindEmployeeDetails();
lblresult.ForeColor = Color.Green;
lblresult.Text = txtDepartment.Text + " Details inserted successfully";
}
else
{
lblresult.ForeColor = Color.Red;
lblresult.Text = txtDepartment.Text + " Details not inserted";
}
}
}
i hope i am clear to you guys
How can I do that?
