I am trying to create a function which creates a certain amount of textboxes depending on how many are in the datatable.
I have the following code so far:
foreach (DataRow row in dataSetselectactivities.Tables[0].Rows)
{
TextBox tb = new TextBox();
tb.Visible = true;
}
but how would I add a new value to the textbox for each row, would it be something like tb.text += dttablevalue
any help would be great
thanks

You need to create Array of Controls instead, to get/set attributes of all textboxes.

ok, ive got this now
public void CreateTextBoxes(Object sender, EventArgs e)
{
foreach (DataRow row in dataSetselectactivities.Tables[0].Rows)
{
TextBoxesHere.Controls.Add(new TextBox());
}
}
I am not showing the datatable in the code above because it would take up too much room but it does exist. Anyway Ive managed to create as many textboxes as there are rows dynamically. However now I need to fill each one with data from the datatable. How do I go about that?
thanks!

public void createTextBoxes(DataTable dt)
{
TextBox txt;
int Count = 1;
foreach (DataRow dr in dt.Rows)
{
txt = new TextBox();
txt.ID = "txt_" + Count;
txt.Text = dr["FieldName"].ToString();
Count+=1;
}
}

thanks!!
OK final question how do I add a break after each textbox i.e
where abouts would I put it, I know the syntax shold be something like + "
" but not sure which line to put it.
also how can I call the code on page_load, at the moment it is called through a button
thanks!

Cann't you use Repeater or DataGrid for this? That will be more simpler. Any way, you will have to create as many Literal Controls as there are textboxs and put it between textboxs to insert some text/html markup between them.
You can take out the code inside the button's click and put it in a method and call it from both the page_load and the button_click.

That would not work as your appending text to the textbox, and browser will not parse it while rendering. As I said, creating literal controls and adding them between textboxs is the way to go if you don't want to use repeater/Datagrid. Can you paste the code which you are using to add these textboxs to the page? Then I may be able to suggest the code to you.

foreach (DataRow row in dataSetselect.Tables[0].Rows)
{
lb = new Label();
tb = new TextBox();
lb.Text = row["field"].ToString();
tb.Text = row["field"].ToString();
TextBoxesHere.Controls.Add(lb);
TextBoxesHere.Controls.Add(tb);
}
thanks it would need to go somewhere in there

Change the line
lb.Text = row["field"].ToString();
to
lb.Text = "<br />" + row["field"].ToString();
This will add a line break before every label.

it throws up an error:
should it be like:
lb.Text = "
" + row["field"].ToString();
or
lb.Text = "" + row["field"].ToString();
|
|

The complete statement should be in a single line. And the quotes should not be empty, it should contain <br />
The line will be:
lb.Text = "<br />" + row["field"].ToString();
I didn't formatted the code correctly last time, sorry.
You can insert any html markup there, since you want a line break, use <br />
Goodluck.

No that doesn work either, all that does is put the <br /> in the actual textbox as text.
I need to add it afterwards but not sure of the syntax
Thanks anyway

Instead of label you can use a LiteralControl
LiteralControl lit=new LiteralControl();
lit.Text="<br />"
Textboxhere.controls.add(lit);
EVEN THE WORD IMPOSSIBLE SAYS I M POSSIBLE.

I am pasting the complete code:
foreach (DataRow row in dataSetselect.Tables[0].Rows)
{
lb = new Label();
tb = new TextBox();
lb.Text = "<br />" + row["field"].ToString();
tb.Text = row["field"].ToString();
TextBoxesHere.Controls.Add(lb);
TextBoxesHere.Controls.Add(tb);
}
Is it the same code as what you are using?

I have the following code. Now this code is working for every row apart from the last one in the gridview, why would this be?
thanks
for (int x = 0; x < GridView1.Rows.Count; x++)
{
GridViewRow row = GridView1.Rows[x];
string strID = GridView1.DataKeys[x].Values[0].ToString();
HyperLink hyp = ((HyperLink)row.FindControl("hl"));
hyp.Attributes["OnClick"] = "alert('You do not have the correct permissions to perform this action');return false;";
hyp.ForeColor = Color.Black;
}

Fixed it, needed to put this code in the ondatabound event rather then on row create event
cheers
|
|
|
|
|
You mean to say that you are looping through all the rows of the gridview inside rowdatabound event?
