I am working in custom detailed view. I have a program page that views all the program. When a user clicks on update button, the user is redirected to manage programs page. The Manage Programs Page contains a method that fetches all the rows from.
public string ProgramsDetails()
{
using (SqlConnection con = new SqlConnection(str))
{
string htmlStr = "";
SqlCommand cmd = con.CreateCommand();
cmd.CommandText = " SELECT * from programs where ProgId=@ProgId";
cmd.Parameters.AddWithValue("@ProgId", "1");
con.Open();
SqlDataReader reader = cmd.ExecuteReader();
if (reader.Read())
{
int ProgId = reader.GetInt32(0);
string ProgTitle = reader.GetString(1);
string ProgBudget = reader.GetString(4);
string ProgStarDate = reader.GetString(5);
}
con.Close();
return htmlStr;
}
}
How can I access a variable from .aspx page? Lets say I would like to access ProgTitle
.
I have used this method but seems it's not working
<%=ProjTitle%>
I would like to show the values of each column in there respected text box
<div class="cmrs-panel-body no-padding">
<div class="cmrs-form-inline">
<div class="cmrs-form-row bordered">
<label class="cmrs-form-label">Program Code Name</label>
<div class="cmrs-form-item">
<input type="text" name="Code" class="large">
</div>
</div>
</div>
<div class="cmrs-form-inline">
<div class="cmrs-form-row bordered">
<label class="cmrs-form-label">Program Title</label>
<div class="cmrs-form-item">
<input type="text" name="Title" class="large" value="<%=ProgTitle %>">
</div>
</div>
</div>
<div class="cmrs-form-inline">
<div class="cmrs-form-row bordered">
<label class="cmrs-form-label">Program Description</label>
<div class="cmrs-form-item">
<textarea class="large"></textarea>
</div>
</div>
</div>
</div>
Normally i would add the html code to method but this is not feasible so i want to get the variable value and display it in textbox.
htmlStr+="<table><tr><td>"+ProgTitle+"</td></tr></table>";
ProgTitle
must be declared as protected
or public
in the code behind to make it accessible from .aspx. Change your code as below
protected string ProgTitle;
public string ProgramsDetails()
{
using (SqlConnection con = new SqlConnection(str))
{
string htmlStr = "";
SqlCommand cmd = con.CreateCommand();
cmd.CommandText = " SELECT * from programs where ProgId=@ProgId";
cmd.Parameters.AddWithValue("@ProgId", "1");
con.Open();
SqlDataReader reader = cmd.ExecuteReader();
if (reader.Read())
{
int ProgId = reader.GetInt32(0);
ProgTitle = reader.GetString(1);
string ProgBudget = reader.GetString(4);
string ProgStarDate = reader.GetString(5);
}
con.Close();
return htmlStr;
}
}
then you can access ProgTitle
in your aspx code
<input type="text" name="Title" class="large" value="<%=ProgTitle %>">
If not using databinding, how about using session and allocate the variable then use it. On code Behing: SESSION.START(); SESSION["PjTitle"]=PrgTtile;
SESSION.START(); SESSION["PjTitle"]=PrgTtile;
and then in aspx acces it with: <%= SESSION["PjTitle"] %>
