Hi All
I am dynamically creating some dropdownlist in the TextBox textchanged event and placing them in a placeholder. Now I want to retrieve all the dropdowns selected value to be inserted into the DB when i press save button. But the problem is that when I press save my place holder gets empty and there is no drop down. How can I do that. I hope I am making sense. Please please help me.....

where did you write the code for add the content ?
could you put you code over here ?
|

Here is the complete code listing.
SqlConnection con = new SqlConnection(ConfigurationManager.AppSettings["MyCon"]);
protected void txtdeptnos_TextChanged(object sender, EventArgs e)
{
plcHolder.Controls.Clear();
for (int i = 1; i <= Convert.ToInt32(txtdeptnos.Text); i++)
{
DropDownList ddl = new DropDownList();
ddl.ID = "ddl" + i.ToString();
ddl.AppendDataBoundItems = true;
ddl.Items.Clear();
ddl.Items.Add("Select Department");
ddl.Width = 130;
ddl.Items[0].Value = "0";
string strfac = "select deptid,deptname from department where bitDeletedFlag=0";
con.Open();
DataSet ds1 = new DataSet();
SqlDataAdapter da = new SqlDataAdapter(strfac, con);
da.Fill(ds1, "department");
ddl.DataSource = ds1.Tables["department"];
ddl.DataTextField = "deptname";
ddl.DataValueField = "deptid";
ddl.DataBind();
con.Close();
plcHolder.Controls.Add(ddl);
plcHolder.Controls.Add(new LiteralControl("
"));
plcHolder.Controls.Add(new LiteralControl("
"));
}
}
protected void BtnSave_Click(object sender, EventArgs e)
{
foreach (Control control in this.plcHolder.Controls)
{
if (control.GetType().Name == "DropDownList")
{
DropDownList dd = (DropDownList)control;
depts = depts + ", " + dd.SelectedItem.ToString();
//I want to concartinate all the selected values of the drop downs and to be inserted into the DB at this click function. But the place holder gets empty. This loop is not executing totally.
Session["val"] = dd.SelectedItem.ToString();
}
}
}

I have solved this now.
It's because I missed out "xmlPing.Close()"
Just thought I'd update this if anyone ever needs the code.

Hi
I am displaying a password field which is part of the login control
However when I start typing in it, it is not showing the text being typed. Normally a circle appears in the textbox for each letter but for mine it is not displaying any text.
The text is still being entered as when I hit enter the page logs in and matches the password.
If any1 knows why this would let me know!
cheers!

Strange. Looks like some CSS issue. If you have applied CSS to the control, try removing it.
|
|

Your right it is sort of a css issue
Basically I'm including a skin in the page and I have the below code in it:
<asp:Textbox runat="server"
ForeColor="Black"
Font-Names="HelveticaNeueLT Std,Arial,Times New Roman,Verdana"
Font-Size="10pt"/>
but when I change Font-names to Font-family all the text is displayed in the wrong font
Is there something I can add in the above code so that it allows visible typing into a password box?
thanks!
|
|
|
|
|
sorted it
I gave the control an ID in the skin and then applied the ID to the password textbox
cheers!

It's the first time I'm dealing with programming a web service. I want to write a method that allows the client to download some files. I created a new folder called 'myFiles' in the Web Service solution.
The web method is this:
[WebMethod]
public byte[] downloadFile()
{
FileStream fs = new FileStream("myFiles\\aaa.txt", FileMode.Open);
byte[] contents = new byte[fs.Length];
fs.Read(contents, 0, (int)fs.Length);
return contents;
}
When I test the function, I get the error:
System.IO.DirectoryNotFoundException: Could not find a part of the path 'C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\myFiles\aaa.xls'.
Why is it looking fot the myFiles folder there. How do I point it to the local folder of the web service application?
Thanks.
|

Use Server.MapPath()
[WebMethod]
public byte[] downloadFile()
{
FileStream fs = new FileStream(Server.MapPath(@"myFiles/aaa.txt"), FileMode.Open);
byte[] contents = new byte[fs.Length];
fs.Read(contents, 0, (int)fs.Length);
return contents;
}myFiles directory should be in the root of WS. Make sure you are closing stream after reading.

I filled DataSet use SqlCommand.
then DetailsView bind dataSet:
DetailsView.DAtaSource = DataSet;
DetailsView.DataMember = "table1";
DetailsView.DataBind();
then AllowPaging. but when running, report:
incident the untreated event,PageIndexChanging.
if use SourceDataControl Bind, navigation page is succeed.
why unsuccessfully with first way?
how do can navigation page succeed?
|
|
|
|
|
In your aspx in the DetailView part you add
OnPageIndexChanging="dv_PageIndexChanging"
in your code behind you add:
protected void dv_PageIndexChanging(Object Sender, DetailsViewPageEventArgs e)
{
LoadDetailView(e.NewPageIndex);
}
protected void LoadDetailView(Int32 pageNumber)
{
DetailsView.DataSource = DataSet;
DetailsView.DataMember = "table1";
DetailsView.Page = pageNumber;
DetailsView.DataBind();
}
may the force be with you

how to replace and trim particular part from string.
string s = '2,5,7,8,9'
now I want to trim ',8' from s
and replace 7 by 15
finally it will be
s='2,5,15,9'
thanks

By trim, you mean replace ,8 with string.Empty. Trimming refers to removing whitespace from the edges.
The string class has a replace method.
This is totally unrelated to ASP.NET.

What this has to do with ASP.NET ? Trimming means removing whitespace and not removing a character. string has a Remove() method, check that. BTW, you could try something like this too
s.Replace("7", "15").Replace("8,", string.Empty)

thanks a lot
