TextBox txt = new TextBox();
txt.ID = ID;
txt.Text = DateTime.Now.ToString();
PlcHolder.Controls.Add(txt);
DropDownList ddl = new DropDownList();
ddl.ID = ID;
string strSql = "SELECT Code,[Name] FROM SDTS_GSTYPE";
DataTable dtBranch = getDataTable(strSql);
ddl.DataSource = dtBranch;
ddl.AutoPostBack = true;
ddl.DataTextField = "Name";
ddl.DataValueField = "Code";
ddl.SelectedIndex = 0;
ddl.DataBind();
PlcHolder.Controls.Add(ddl);
This is the code i have written to create a textbox.Now how do i get the textbox value and selected value of dropDownlist in my buttonClick event.

first,
The first,
you should know basic first Page Postback ...
every time you create dynamic controls in codebehind, even when you do click on a control button, the page is always postback, and automatically you will never get the value out of control, even control was not there at all when you try to use the event FinControl ...
so, you have to declare the event re-create control when page IsPostBack.
This sample code to start what you want .. this is just a beginning to open its forward your logic .. you can add it from the code sample I gave .....
protected void Page_Load(object sender, EventArgs e)
{
if(!Page.IsPostBack)
{
GenerateControlSelf();
}
else
{
var txt = new TextBox { ID = "tbx", Text = DateTime.Now.ToString(CultureInfo.InvariantCulture), ClientIDMode = ClientIDMode.Static };
holder.Controls.Add(txt);
var ddl = new DropDownList { ID = "ddlx" };
var nextYear = Convert.ToInt32(DateTime.Now.Year.ToString(CultureInfo.InvariantCulture)) + 1;
var lastYear = Convert.ToInt32(DateTime.Now.Year.ToString(CultureInfo.InvariantCulture)) - 10;
for (var n = lastYear; n < nextYear; n++)
{
ddl.Items.Add(n.ToString(CultureInfo.InvariantCulture));
}
ddl.AutoPostBack = true;
ddl.SelectedIndex = 0;
ddl.DataBind();
holder.Controls.Add(ddl);
}
}
private void GenerateControlSelf()
{
var txt = new TextBox { ID = "tbx", Text = DateTime.Now.ToString(CultureInfo.InvariantCulture) ,ClientIDMode = ClientIDMode.Static};
holder.Controls.Add(txt);
var ddl = new DropDownList {ID = "ddlx"};
var nextYear = Convert.ToInt32(DateTime.Now.Year.ToString(CultureInfo.InvariantCulture)) + 1;
var lastYear = Convert.ToInt32(DateTime.Now.Year.ToString(CultureInfo.InvariantCulture)) - 10;
for (var n = lastYear; n < nextYear; n++)
{
ddl.Items.Add(n.ToString(CultureInfo.InvariantCulture));
}
ddl.AutoPostBack = true;
ddl.SelectedIndex = 0;
ddl.DataBind();
holder.Controls.Add(ddl);
}
protected void Button1_Click(object sender, EventArgs e)
{
foreach (Control ctl in holder.Controls)
{
if (ctl is DropDownList)
{
DropDownList ddl = (DropDownList) ctl;
object x = ddl.SelectedItem;
}
}
foreach (Control ctl in holder.Controls)
{
if (ctl is TextBox)
{
TextBox tbx = (TextBox)ctl;
object x = tbx.Text;
}
}
}
I remind you again, the sample code is just for starters only, to pave the way you are thinking ...

Hi,
I am using this code to upload using Ajaxuploader:
using (Stream stream = item.OpenStream())
{
using (System.Drawing.Image img = System.Drawing.Image.FromStream(stream))
{
img.Save(Server.MapPath(String.Format("{0}/{1}/posts/{2}/{3}.png", Application["MemberMediaDirectory"], Session["volow_member_guid"], RouteData.Values["GUID"], image_guid)), ImageFormat.Png);
}
}
I want to know how can I resize the image before uploading to 906width X 360height?

You can't. submitting files to a website is voluntary, and the user has to choose which files to submit.
Websites that run in a browser on the client system run in a protective bubble, that is separated from the operating system. Sort of a sealed container.
You can resize the image after uploading by using system.drawing, measuring the size of the uploaded image, calculating the new height and width, and the new canvas size, and then creating a new blank canvas, and then overlay the original image over the canvas and save the new file.
Or you can write several programs in c++ to run on the client computer such as Linux, OSX, Windows, that will resize, and transmit the new bytestream to a webservice as a non-primitive, and then make the write to the disk drive.

Have a look at Plupload[^]. In a modern browser, it supports resizing PNG and JPEG files before uploading.

Hi,
Why I am getting the above error for this line:
TitleLabel.Text = data_table.Rows[0]["post_category_name"].ToString() + " - " + data_table.Rows[0]["member_channel_name"].ToString();
here is my stored procedure:
BEGIN
SELECT DISTINCT
post_category.post_category_guid,
post_category.post_category_name,
web_members.web_member_guid,
member_channels.member_channel_address,
member_channels.member_channel_name
FROM
post_category
INNER JOIN member_posts ON member_posts.member_post_category = post_category.post_category_id
INNER JOIN member_channels ON member_posts.member_channel_id = member_channels.member_channel_id
INNER JOIN web_members ON member_channels.web_member_id = web_members.web_member_id
WHERE member_channels.member_channel_address = param_web_address;
END

As per your code, it does not seem issue here. I'll advise you first run your Proc and see whether it is running and resturning data correclty.
Then you debug your code and check the datatable in immidiate window and see it in visualiser what columns are available in datatable.

So you get the error "Hi"
Never seen that error before. That's a new one for me.

Hello *,
I aked my question a few days ago on stack overflow but I'am not lucky with the one answer. Perhaps, someone can help me here.
My first controller method is:
[HttpGet]
public ActionResult Item()
In this method, I have some business logic like retrieve the user id with sql or watch out if a user has the permission to see some regions on the view or whatever.
I used bool variables in my viewbag and get these data with razor.
It's only one case..
Now, the user is going to fill data in a form, will make a post and then I call the same method, but with a [HttpPost()] flag (I saw it in many tutorials).
[HttpPost]
public ActionResult Item(FormCollection formCollection)
Ok, now I can collect the values out of the form and can work with them.
BUT if this function is ready, it gives as standard View() back and I can't made the business logic like in the Get() method or must I really copy/pase all these stuff or get it in a own function and call it two times?
Here is a link to my stack overflow question, perhaps you unterstand me better with that:
