Dynamic <DIV> tag??? 2

[jbenson001]

Hello all,

I am creating a form by adding controls dynamically. One of my controls is a DataGrid which has about 20 rows. In the past when not creating the form dynamically, I put the grid inside of a <DIV> tag so that I can have scroll bars to appear. I know the <DIV> tag is HTML, but is there anyway to add it at run time, around my grid, or am I way off here? Thanks for any help and suggestions.

You could always add the div tag at design time (and place the datagrid in it) then when needed add the attributes to add the scrollbars i.e. so it always exists but only becomes visible if you want it to.

The problem is the whole usercontrol is built dynamically. The DIV can appear anwhere on the control

In that case I guess you could add it at runtime but you would have to do it in a sensible order. e.g.

1) Add the DIV tag
2) Add a copy of the DataGrid control to the div
3) Remove the original copy of the DataGrid

I do something similar using to use Inheritance so each of my pages inherits from a page base class. The same kind of principle is applied in that page base i.e.

1) Create a new form
2) Add all of the controls from the original form to the new form
3) Add all of my controls that I want to appear on each page
4) Remove all the original controls

I hope you understand what I mean as it's getting a bit late here and I'm not sure if I'm making sense!

Thanks for the response. I will keep it in mind. I am currently looking into using the HTMLTextWriter. Maybe this will be the way to go.

I don't see why you have to use a htmltextwriter. You could dynamically create a div and add your datagrid with:

System.Web.UI.HtmlControls.HtmlGenericControl div = new System.Web.UI.HtmlControls.HtmlGenericControl("DIV");

div.Controls.Add(Your datagrid control);

You could also you a panel, but it seems that a panel only generates a div for IE and for anyother browser, it generates a table.

Thank you so much for the help! The examples I saw didn't show what you did.

I used this (using VB)

        Dim mydiv As System.Web.UI.HtmlControls.HtmlGenericControl
        mydiv = New System.Web.UI.HtmlControls.HtmlGenericControl("DIV")

        Me.Controls.Add(mydiv)

I can't tell you how happy I am for your help. Thank you so much again!!!!

I just realized on problem however. By adding this code I get <DIV></DIV>

What I need is this

<DIV>
a datagrid here
</DIV>

Any Ideas????

 

[jbenson001]

Nevermind, sorry, I figured it out. Just added the controls I wanted to the collection of the div.

 

[jbenson001]

I completely miss you showing me the adding of the DG to the div. I guess I was to quick in my reading

THANKS!!!!!!

1) Add the DIV tag
2) Add a copy of the DataGrid control to the div
3) Remove the original copy of the DataGrid

That's what I was trying to explain with my above quote (I told you I wasn't making much sense! Guess I should have included an exmple).

if i understood u correctly this may also work:
<DIV runat="server" id="TheDiv">


in code behind file:
Protected WithEvents TheDiv as HtmlGenericControl


if u want a scroll to appear:
TheDiv.Attributes.Add("style","overflow:auto")

vbkris - That's what I suggested in my first post, but the poster explained that it wasn't possible.
