Web Forms :: Setting Checkbox Values Through Datareader
Feb 3, 2011
I have a form with a checkbox list, the values of which are value = "1" value = "2' ...etc (amount of boxes not fixed). These values correspond to an id field in a database and are stored when a new user is entered. When reloading this info I want to populate the checkboxes according to how the user originally checked them.
What is the correct way to do this?
while (reader.Read())
(
i = Convert.ToInt16(reader["Id"]);
CheckboxList1.Items.FindByValue[i].Selected = true;
}
doesn't work....

Why can I not call the global variables CatCode and CompanyName which are equated in the first procedure GetCompanyCatID And use their new values in the second procedure UpdateCompanyCounts as parameter values. When I hard code them code their values at the end of the GetCompany CatID procedure the following procedure updates properly.
string CatCode; - delcared global
string CompanyName; - delcared global
protected void GetCompanyCatID()
{
LinkID2 = Request.QueryString["linkid"].ToString();
string L_ID = LinkID2;
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString001"].ConnectionString);
SqlCommand cmd = new SqlCommand("GetCID", con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@L_ID", L_ID);
try
{
con.Open();
using (SqlDataReader reader = cmd.ExecuteReader())
{
while (reader.Read())
{
if (reader["CG_ID"] != System.DBNull.Value)
CatCode = (string)reader["CG_ID"];
CompanyName = (string)reader["CG_Name"];
}
}
}
catch (SqlException exc)
{ }
finally
{ con.Close(); }
// ******* HARD CODED to test below update procedure, it works. When commented out the following update procedure does not update.
CatCode = "55555"
CompanyName = "Test";
UpdateCompanyCounts();
}
protected void UpdateCompanyCounts()
{
LinkID2 = Request.QueryString["linkid"].ToString();
string L_ID = LinkID2;
string CatCode2 = CatCode;
string CompanyName2 = CompanyName;
// string CatCode2 = "23456";
// string CompanyName2 = "TEST";
SqlConnection con2 = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString001"].ConnectionString);
SqlCommand cmd2 = new SqlCommand("UpdateCatCounter", con2);
cmd2.CommandType = CommandType.StoredProcedure;
cmd2.Parameters.AddWithValue("@L_ID", LinkID2);
cmd2.Parameters.AddWithValue("@CG_ID", CatCode2 );
cmd2.Parameters.AddWithValue("@CG_Name", CompanyName2 );
try
{
con2.Open();
cmd2.ExecuteNonQuery();
}
catch (SqlException exc)
{
// ErrorBox.Text += string.Format("Error: {0}<br/>", exc.Message);
}
finally
{
con2.Close();
}

I have the following code
public class ProductDetails
{
private string _productid;
public string ProductID
{
get { return _productid; }
}
private string _description;
public string Description
{
get { return _description; }
}
private string _image;
public string Image
{
get { return _image; }
}
public ProductDetails(string productid, string description, string image)
{
_productid = productid;
_description = description;
_image = image;
}
}
public class DataAccess
{
private static string connectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
public ProductDetails GetProductDetails()
{
SqlConnection con = new SqlConnection(connectionString);
SqlCommand cmd = new SqlCommand("ProductDetails", con);
cmd.CommandType = CommandType.StoredProcedure;
string productid = HttpContext.Current.Request.QueryString["productid"];
cmd.Parameters.Add(new SqlParameter("productid", SqlDbType.NVarChar)).Value = productid;
con.Open();
SqlDataReader reader = cmd.ExecuteReader();
reader.Read();
ProductDetails pro = new ProductDetails(
(string)reader["ProductID"], (string)reader["Description"], (string)reader["Image"]);
reader.Close();
return pro;
}
}
protected void PopulateControls()
private DataAccess da = new DataAccess();
{
ProductDetails product = da.GetProductDetails();
if (product.Description == String.Empty)
{
lblDescription.Visible = false;
}
else
{
lblDescription.Text = product.Description;
}
}
In the last piece i want to check if the Description field is null or empty in order to hide the label control but i get an error if i write: if (product.Description == DBNull.Value) and can only use ring.Empty. But i want to check for NULL values as well..

I'm having a method that exports content from the database to excel files. The method taks as paramaters a DataReader param and a int param - the number of rows. For the number of rows i'm using a dataset, wich i fill using the same query as for the datareader. So I'm executing it twice... Is there a way I can avoid that? get the number of rows from the datareader?

I can check the value of a checkbox in a GridViewRow:
isChecked = CType(row.FindControl("chkSelect"), CheckBox).Checked
But what's baking my noodle is trying to figure out how to programmatically set a checkbox to checked.
The scenario is I have some rows in a GridView that are associated to another value in a dropdown. So, when I select the value in the dropdown, I'd like the checkboxes in the GridViewRows that are associated with that value to be already checked.
Problem: The check value is not persisted in the database. There's no field for it. The checkbox on the GridViewRows is an ASP TemplateField.
So I iterate through the rows and would like to check whichever checkboxes I need to based on whatever condition.

I have some user controls which have properties which need to be set from a form on the page
<uc1:MyPlugin
ID="MyPlugin2"
runat="server"
Property1="Hi"
Property2="0" Property3="<%=Property3%>"
Property4="<%#Property4
%>"
/>
Property3 and Property4 anre both public properties of the page I am on and the user control
Currently the code complaing about Property3 saying it cannot create an object of Int32 from '<%=Property3%>' and Property4 always gets set to 0 (the default)
I do not wish to use the c# code to set these values as this Plugin will be deployed with a CMS which I have no control over

Background: I open a page that has a detailsview control using Accessdatasource. It is automatically opened with the row I want to update as I get there by passing the key as a URL parm. The update works for all fields except 2 template fields I added. I added a field for update date and updated by which I want the code to populate in the code behind so the user does not enter it. I have the same login on another page using an insert and it works fine. I cannot figure out what is wrong on the update and I tried everything. The code behind is in the OnItemUPdating event. code behind:
protected void set_update_date(Object sender, EventArgs e)
{
TextBox tbdate = (TextBox)DetailsView1.FindControl("TextBox_update");
