Read Records one by one from the sheet and insert it into the desired table. the below function will help you in returning table from the Excel Sheet but the sheet name should be Sheet1. if change ..then change the code i have highlighted with underline(bold)
public DataTable getDataFromXLS(string strFilePath)
{
try
{
string strConnectionString = string.Empty;
strConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + strFilePath + ";" + "Extended Properties=Excel 8.0;";
OleDbConnection cnCSV = new OleDbConnection(strConnectionString);
cnCSV.Open();
OleDbCommand cmdSelect = new OleDbCommand(@"SELECT * FROM [Sheet1$]", cnCSV);
OleDbDataAdapter daCSV = new OleDbDataAdapter();
daCSV.SelectCommand = cmdSelect;
DataTable dtCSV = new DataTable();
daCSV.Fill(dtCSV);
cnCSV.Close();
daCSV = null;
return dtCSV;
}

I have a text box and a set of checkboxes in my form. The textbox is dynamically created.
There is a postback event on the textbox as OnTextChangedEvent and I am checking for a condition in the database with the text entered in textbox.
The issue is whenever the OnTextChangedEvent fires and if the user checks any of the checkboxes, the checkbox is getting cleared. Obviously, this is the nature of web application.
I want to know, whether there is any way to preserve the checked state of checkbox even after postback. I couldn't use the updatepanel because it is dynamically created textbox. I'm just using a placeholder for that. I don't want to place a button next to that. Because then, I need to track whether the user has to click the button etc.
Is there anyway to put the code only in textchange event and keep the changes in other controls without using the update panel?
Success is the good fortune that comes from aspiration, desperation, perspiration and inspiration.

Are you generating textboxes inside gridview control OR in table.?
if you are using the gridview find the control by ControlType
if the control is textbox then get its text.
foreach (GridViewRow row in grdName.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
foreach (Control ctrl in row.Controls)
{
if (ctrl is TextBox)
{
TextBox txt = (TextBox)ctrl;
string str = txt.Text;
}
}
}
}
Get the text as above.

I m generating textboxes in the panel
|
|
|
|

i have tried the below code and i am getting the text from the text box.
i have generated the Textboxes in page_Load
and accessed the textbox text on button_Click
<table>
<tr>
<td colspan="2">
<asp:Panel ID="Panel1" runat="server" Height="200px" Width="125px">
</asp:Panel>
</td>
</tr>
<tr>
<td style="width: 100px">
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" /></td>
<td style="width: 100px">
</td>
</tr>
</table>
Code.
protected void Page_Load(object sender, EventArgs e)
{
for (int i = 0; i < 4; i++)
{
TextBox t = new TextBox();
t.Width = Unit.Pixel(160);
t.Height = Unit.Pixel(22);
Panel1.Controls.Add(t);
}
}
protected void Button1_Click(object sender, EventArgs e)
{
string str = "";
foreach (Control ctrl in Panel1.Controls)
{
if (ctrl is TextBox)
{
TextBox t = (TextBox)ctrl;
str = t.Text;
}
}
}
i am getting the text i entered in the textboxes. In your case implement it as you required.

Java Script does not have the sufficient right to do this.
Probably ActiveX can be a alternative solution. But it will work only on IE

hi..
in my page n number of fields are there.user may enter some fields maynot enter some fields.so i am not using required field validator.I just want to check with valuetype.so i am using regular expression validator for name to allow lower & upper case letters and space,' etc.see code below.
i am entering only those letters only eventhough error message is coming.why??<br />
<td align="left"> <asp:TextBox ID="fname" runat="server" ToolTip="First Name" MaxLength="15" CssClass="textbox" /></td><br />
<br />
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" SetFocusOnError="true" Display="Dynamic"<br />
ControlToValidate="fname" ValidationExpression="[a-zA-Z''-'\s]" ErrorMessage="invalid entry"></asp:RegularExpressionValidator>
|

Your regular expression probably demands a value. You need to create a regular expression that will pass on an empty input as well as any valid filled in input.
|
|
|
|
|
There is a property on these validators, it's something like 'validateifempty'. I forget the name, but I think that's what you need.
Oh, it looks to me like your regex is for only one character. I think you need a * after it.

Hello,
I was looking on the web to find any samples that walk you through doing this in C#....I don't even see it on webSupergoo's website (the cretor of abcPDF)
I need to be able to convert documents (could be any format really) dynamically into PDF before they are sent to a Adobe server for annotations and stuff using Adobe LifeCycle Reader extensions.
Note: I cant use adobe to perform this conversion though!
Any help would be appreciated!
Thanks
Tina
