I am creating a button, a textbox and a label control, when a linkbutton is clicked. I have assigned an event handler to the button, but when the button is clicked nothing happens and even the previous controls created, disappear
<br />
protected void LinkButton2_Click(object sender, EventArgs e)<br />
{<br />
<br />
TableRow row = new TableRow();<br />
TableCell cell1 = new TableCell();<br />
txt = new TextBox();<br />
txt.Rows = 2;<br />
txt.Height = 40;<br />
txt.Width = 200;<br />
cell1.Controls.Add(txt);<br />
row.Controls.Add(cell1);<br />
<br />
btn = new Button();<br />
btn.Text = "Submit";<br />
btn.Click += new EventHandler(btn_Click);<br />
TableCell cell2 = new TableCell();<br />
cell2.Controls.Add(btn);<br />
row.Controls.Add(cell2);<br />
<br />
lbl1 = new Label();<br />
lbl1.Text = "Your Comments";<br />
TableCell cell3 = new TableCell();<br />
cell3.Controls.Add(lbl1);<br />
row.Controls.Add(cell3);<br />
Table1.Controls.Add(row);<br />
<br />
<br />
}<br />
void btn_Click(object sender, EventArgs e)<br />
{<br />
<br />
<br />
<br />
}<br />

You need to create all dynamic control before page_Load, best to create them on Page_PreInit. Other wise the control will not able to maintain viewstate and postback data. As LoadPostBack and LoadViewState Fired before Page_Load.

When recreating the controls in Page_PreInit, the line
<br />
Table1.Controls.Add(row);<br />
gives an error.

Hi all,
I need to get the total number of records into GridView outside the any event of gridview.
If I use GridView1.Rows.Count, then it just returns me the total number
of rows on the page.
But if I have, 5 pages having 10 records per page and 45 records total,
Rows.Count will return me 10 on the first 4 pages, and 5, on the last page.
But I need to get total number of record without using the gridview1's datasource like dataset or dataview etc. I need to use only n only gridview1 property.
Thanks,
Sri...

Then why you are not counting the Rows of your DataSource ?

I am doing the following thing
protected void Button1_Click(object sender, EventArgs e)
{
int recordCount;
DataSet ds=(DataSet)GridView1.DataSource;
recordCount = ds.Tables[0].Rows.Count;
Response.Write(recordCount);
}
get error "Object reference not set to an instance of an object." stating ds.Tables[0] is null.
I am not getting why this is happing even i am binding the gridview in page load under if(!IsPostBack).
Thanks,
Sri...

Suppose GridView is gr
int k=gr.PageSize*(gr.PageCount-1);
gr.Currentpage=gr.PageCount-1;
int p=gr.Rows.Count ;
int GridRows= k+p;
Try this I think you could get with a minor modification

Thanks Nishant,
You code is fine but we need to find the number of rows in the page of gridview to calculate the total number of rows in grid view. Any idea to find the number of rows in the last page??
Thanks,
Sri...

Can you try with the paging to false and then check the recordcount after that u can make the paging as true.

Hi Prasant,
I am doing the following things:
protected void Button1_Click(object sender, EventArgs e)
{
GridView1.AllowPaging = false;
Response.Write(GridView1.PageCount.ToString());
GridView1.AllowPaging = true;
}
Still getting 10 rows as rows on current page.
Thanks,
Sri...

Hi Srinandan,
Set the page count to Last page
gr.CurrentPageIndex=gr.PageCount-1;
gr.Rows.Count You will get the rows on the last page .

Remove the ASP:Content Tage. Use Normal HTML Tag like other pages.

This will not work in a normal textbox control.
|
|
|
|

I am afraid it is impossible to do that.
You can use other controls or div with <b></b>.

As far as i know, you cannot do this in a normal textbox control.
Try to use some HTML Editor control.

If you are mentioning the page name and if it changed then you have to change every where. You can also pass page name as argument.
