Hello,
I have a grid view with one column and populated that with the following code,
GridView1.DataSource = PropList;
GridView1.DataBind();
Where PropList is a List of string .
Now I have added another column in the GridView1 by the following code
BoundField b;
b = new BoundField();
b.HeaderText = "new1";
GridView1.Columns.Add(b);
Now my problem is that if I have another list of string, How i Add that list to the new column.
Please help me in this regards.
Thanks

You cannot. You'd need a list of a struct which has two properties, as you can only bind to one source, but you can set the columns to pull data from properties of items in your list.

Hi All,
Is there any other way except <div>
to place multiple forms in one page. I am doing development in ASP.Net 2.0.
Please suggest and have a nice day!!.

When you ask about divs, you're asking about HTML. ASP.NET is therefore irrelevant. The answer is that you can break stuff up on a page many ways, but if you want multiple forms on a page ( aspx files ), you can't do it. You can create as many pages as you like as controls ( ascx files ) and put as many of those on a page as you like.

Thanks!! I understand Div are part of HTML. Ok let me put my question in this way...I have three forms say a.aspx,b.aspx, c.aspx and i want to display all them in one go in browser.
All three forms are having their own controls and buttons which will do different action. So user can submit relevant form back to server.
Any views?

Hi
my gridview is below:
<asp:GridView ID="GridView1" runat="server" AllowSorting="True" AutoGenerateColumns="False"
CellPadding="0" EmptyDataText="-- Kayıt Yok --" GridLines="Horizontal" Width="100%">
<RowStyle CssClass="TDS" />
<AlternatingRowStyle CssClass="TDS" BackColor="#F7F6F3" />
<Columns>
<asp:BoundField DataField="title" HeaderText="Kongre Adı">
<HeaderStyle CssClass="TDColoredHeader" HorizontalAlign="Left" VerticalAlign="Middle" />
</asp:BoundField>
<asp:BoundField HeaderImageUrl="~/images/seperator.gif">
<ItemStyle Width="2px" />
<HeaderStyle CssClass="TDColoredHeader" />
</asp:BoundField>
<asp:TemplateField HeaderText="Sil">
<ItemTemplate>
<asp:TextBox runat="server" CssClass="Textbox" ID="Textbox1" Text=""
MaxLength="200" Width="100%"></asp:TextBox>
</ItemTemplate>
<ItemStyle Width="200px" />
<HeaderStyle CssClass="TDColoredHeader" HorizontalAlign="Center" VerticalAlign="Middle" />
</asp:TemplateField>
</Columns>
</asp:GridView>
When i run the project, i cannot see the Textbox on the page. What's my mistake?
If i don't add a server-side control, it works. But i have to add a server-side control.

Hi.....
One of the my webform contain some dropdownlist and
text box (multiline).Suppose there is a data entry operator
filling any employee information while filling information he
can't remember some information about employee and he fill
some information in textbox and select some value ifrom dropdown
list and then he goes to other 2-3 different form and read the
information that he need and come back to origenal
page where he filling the information.When he come then all
the information that he fill before going to other page should
be remain as it before.
How can i do this? i am tying session but session hav a limit to
store data in it and the operator can fill a large amount of data.
how can i do this?Is there any other way?
df

Don't know if this will help but why don't you append the operators text in a string builder and set the Session equal to the string builder. Its only one object... so when u read from the session cast the session data to a string builder and read from it.

Hi MaYo69
but we know session have a limit to store the value in it.
If the user write a more data in text box that could exceed
session limit then in that case we having some error or we
got nothing?Any other option that that?
Do u know HashTable can store the values in it when user navigate
from one page to different like session store the value.
df

|

Hi,
I'm not too sure about HashTable. Only thing I used so far is Session, but it's probably cause I never reached the Session limit.
Soz I couldnt help

Hi
You have to maintain state of page because web applications are stateless. So i would suggest store the info in SQL or any other database before leaving the page. Other way could be viewstate. But you need to take care that view state can slow down the application or site.
I hope this helps you.

Hi Amit,
Do you know any other option than that?Can we do it using javascript?
df
|
|
|
|

You have to choose from cookies, sessions, viewstate, out proc (SQL), Query string. So i will go for SQL....Long way is also there throgh Java Script ie. Callbacks (behind the scene)...

Go for java script.
function IsNumeric(sText)
{
var ValidChars = "0123456789";
var IsNumber=true;
var Char;
var NumberofDots=0;
for (i = 0; i < sText.length && IsNumber == true; i++)
{
Char = sText.charAt(i);
if (ValidChars.indexOf(Char) == -1)
{
IsNumber = false;
}
} // end of for loop
return IsNumber;
} // End of IsNumeric function

Hi all,
I want to export reports in my database to snapshot viewer files.
Access.ApplicationClass app = new Access.ApplicationClass();<br />
app.AutomationSecurity = 1;<br />
app.OpenCurrentDatabase( "c:\\data\\Copy of ITS2005.mdb", false, "" );<br />
app.DoCmd.OutputTo( Access.AcOutputObjectType.acOutputReport, "Licenced Fabricators", "Snapshot Format (*.snp)", "c:\\OMFS.snp", Type.Missing, Type.Missing, Type.Missing);<br />
app.DoCmd.Quit( Access.AcQuitOption.acQuitSaveNone );
This works perfectally fine in a windows form but the OpenCurrentDatabase just doesnt want to finish executing in ASP.NET Page.
Any help would be appreciated!
André.

sorry but i dnt know if my answer will help u by any way or not. but i done xls report of database in my site. here is what i done earlier . there are two ways..
(but at final i used dataset and manually write .. to Responce. which is working fine and is Live)-----
#region old code
//Response.Clear();
//Response.Buffer= true;
//Response.ContentType ="application/vnd.ms-excel";
//Response.Charset = "";
//this.EnableViewState = false;
//System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
//System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
//this.ClearControls(Dgreport);
//Dgreport.RenderControl(oHtmlTextWriter);
//Response.Write(oStringWriter.ToString());
//Response.End();
#endregion
----------------------------------------------------
//try
//{
#region old code diff way
/*DataSet tempds2=new DataSet();
tempds2=getReportData();
if(!(tempds2.Tables[0].Rows.Count<=0))
{
string fileName = "Report.xls";
string FullPath = Server.MapPath("\\")+fileName;
tempds2.WriteXml(FullPath,XmlWriteMode.WriteSchema );
FileInfo file=new FileInfo(FullPath);
if(file.Exists)
{
Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);
Response.AddHeader("Content-Length", file.Length.ToString());
Response.ContentType = "application/vnd.ms-excel";//"application/octet-stream";
Response.WriteFile(file.FullName);
}
}*/
#endregion

Thanx for the reply,
Some questions, what exactly does this getReportData() method do and is it a custom method??
If your solution worked for u, can u perhaps supply he with a solution or code file plz?
Otherwise dont you know of another way to export reports 
|
|
|
|
|
ya both the methods i given worked for me. the getReportData() is custom function wich return me dataset. and first method is useful if u want to export data u are seeing in datagrid (paging =true). but i moved to second because i wanted to export the whole dataset to xls not the page in datagrid.
the third method i am using is not logical but works perfect for my clients requirement. take the data from database in dataset and simple generate the xls using . on 'export to excel' button click with javascript i open blank web form where on page load i write following code. u can pass dataset to this page or get datadet on this pageload.
i hope u will get the useful from below--
Response.Clear();
Response.Buffer= true;
StringBuilder responce_=new StringBuilder();
StringBuilder header=new StringBuilder();
header.Append(""+
"");
header.Append("");
header.Append("");
header.Append("");
header.Append("");
header.Append("");
header.Append("");
header.Append("");
header.Append("");
header.Append("");
header.Append("");
header.Append("");
if(!(tempds2.Tables[0].Rows.Count<=0))
{
for(int i=0;i<tempds2.tables[0].rows.count;i++)
{
responce_.append("<tr>");
for(int j=0;j<tempds2.tables[0].columns.count-1;j++)
{
if(j==0 )
{
responce_.append("<td="" width="70" align="center">"+tempds2.Tables[0].Rows[i].ItemArray[j].ToString()+"");
}
else if(j==1 || j==2 )
{
responce_.Append("");
}
else if(j==3)
{
responce_.Append("");
}
else
{
responce_.Append("");
}
}
responce_.Append("");
}
}
responce_.Append("");
responce_.Append(""+
""+
" | | | | | "+
" | | | | | " +
"Customer Details Report "+ " | | Customer ID | Customer Name | Address | City | Country | Phone Number | Mobile Number | Fax Number | Email | Entry Date | | "+tempds2.Tables[0].Rows[i].ItemArray[j].ToString()+" | "+tempds2.Tables[0].Rows[i].ItemArray[j].ToString()+" | "+tempds2.Tables[0].Rows[i].ItemArray[j].ToString()+" | | " +tempds2.Tables[0].Rows.Count+ " Records Found. "+ " |
");
Response.ContentType = "application/vnd.ms-excel";
Response.Write(header.ToString()+responce_.ToString());
Response.Charset="";
Response.End();
dnt forget to write last statement.
