By default session will be automatically cleared after 20 min of unusage.
In your case are you sure you are not assigning new value for the session in the page load?
|
|
|
|
|
Sure i am not.
sometimes it works from the first click(the session is not cleared),
but after the second click it is cleared !!!
|
|
|
|
|
try to put a link button instead of hyperlink and trace
the code to see where the session is being cleared

You can read excel into a dataset and then can dispay it easily using grid view of whatever control you prefer.
int workSheetNumber = 0;
OleDbConnection ExcelConnection = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + FilePathWithName + ";Extended Properties=Excel 8.0;");
OleDbCommand ExcelCommand = new OleDbCommand();
ExcelCommand.Connection = ExcelConnection;
OleDbDataAdapter ExcelAdapter = new OleDbDataAdapter(ExcelCommand);
ExcelConnection.Open();
System.Data.DataTable ExcelSheets = ExcelConnection.GetOleDbSchemaTable(System.Data.OleDb.OleDbSchemaGuid.Tables, new object[] { null, null, null, "TABLE" });
string SpreadSheetName = "[" + ExcelSheets.Rows[workSheetNumber]["TABLE_NAME"].ToString() + "]";
DataSet ExcelDataSet = new DataSet();
ExcelCommand.CommandText = @"SELECT * FROM " + SpreadSheetName;
ExcelAdapter.Fill(ExcelDataSet);

Hi to all forum members.
I am stuck in implementing ModalPopupExtender in <asp:CommandField in grid view.
Although below code is working fine in <asp:template field in grid view.
<asp:TemplateField HeaderText="Delete" HeaderStyle-CssClass="tableheading" HeaderStyle-Width="70px">
<ItemTemplate>
<center>
<asp:ImageButton ID="imgDelete" runat="server" OnClientClick="showConfirm(this); return false;"
ImageUrl="~/Images/delete.png" OnClick="imgBtnDelete_Click" /></center>
</ItemTemplate>
</asp:TemplateField>
following is my code which I am trying to implement in <asp:CommandFiel in grid view.
.aspx code
Grid view code
<asp:CommandField HeaderText="Edit/Delete" ItemStyle-HorizontalAlign="Center" CausesValidation="false"
ShowCancelButton="true" ShowEditButton="True" ShowDeleteButton="true" />
modal popup code
<ajaxToolkit:ModalPopupExtender ID="md1" runat="server" BackgroundCssClass="modalBackground"
BehaviorID="mdlPopup" CancelControlID="btnNo" OkControlID="btnOk" OnCancelScript="cancelClick();"
OnOkScript="okClick();" PopupControlID="Confiramtiondiv" TargetControlID="Confiramtiondiv">
</ajaxToolkit:ModalPopupExtender>
<div id="Confiramtiondiv" runat="server" align="center" style="display: none">
<table id="Table3" cellpadding="1" cellspacing="1" border="0" bordercolor="blue"
runat="server" align="center">
<tr>
<td colspan="4" align="center">
<asp:Label ID="lblConfirmmsg" runat="server" Text="Are you sure you want to delete this Trip ?"
CssClass="lblConfirmmsg"></asp:Label>
</td>
</tr>
<tr>
<td width="20%">
</td>
<td width="30%">
<asp:Button ID="btnOk" runat="server" Text="Yes" CausesValidation="false" Width="50px" />
</td>
<td width="30%">
<asp:Button ID="btnNo" runat="server" CausesValidation="false" Text="No" Width="50px" />
</td>
<td width="20%">
</td>
</tr>
</table>
</div>
.cs code
protected void grdTrips_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowState != DataControlRowState.Edit) // check for RowState
{
if (e.Row.RowType == DataControlRowType.DataRow) //check for RowType
{
string id = e.Row.Cells[0].Text; // Get the id to be deleted
LinkButton lb = (LinkButton)e.Row.Cells[8].Controls[2]; //cast the ShowDeleteButton link to linkbutton
if (lb != null && lb.Text == "Delete")
{
lb.Attributes.Add("onclick", "showConfirm(this); return false;"); //implementing Ajax modal popup extender
}
}
}
Java Script Function
// keeps track of the delete button for the row
// that is going to be removed
var _source;
// keep track of the popup Confiramtiondiv
var _popup;
function showConfirm(source){
this._source = source;
this._popup = $find('mdlPopup');
// find the confirm ModalPopup and show it
this._popup.show();
}
function okClick(){
// find the confirm ModalPopup and hide it
this._popup.hide();
// use the cached button as the postback source
__doPostBack(this._source.name, '');
}
function cancelClick(){
// find the confirm ModalPopup and hide it
this._popup.hide();
// clear the event source
this._source = null;
this._popup = null;
}
This code opens modal popup but its does not goes to RowDeleting Event of gridview
.
When I changed this code
lb.Attributes.Add("onclick", "showConfirm(this); return false;");
to
lb.Attributes.Add("onclick", "showConfirm(this);");
it open the modal popup but then directly goes to to grid view RowDeleting Event of gridview with out asking confirmation from the users.
I again told this code is working fine in <asp:templatefield.

Dear all,
I was doing a calculation on the total of costs using datagrid. There are only two row in my data. I use the following to insert the summary to the footer but is not success which is as below:
For RawCount = 0 To ItemCount - 1
Quantity(RawCount) = Me.dtGrid.Items(RawCount).Cells(2).Text
Price(RawCount) = Me.dtGrid.Items(RawCount).Cells(5).Text
Costs(RawCount) = Quantity(RawCount) * Price(RawCount)
Me.dtGrid.Items(RawCount).Cells(6).Text = Costs(RawCount)
TotalQuantity = Quantity(RawCount) + TotalQuantity
TotalCost = TotalCost + Costs(RawCount)
If Me.dtGrid.Items(RawCount).ItemType = ListItemType.Footer Then
Me.dtGrid.Items(RawCount).Cells(2).Text = TotalQuantity
End If
Could anyone please help me check what is the problem and why the data is not display in my footer raw?
Thank you so much for the help!

Hi all,
Use the google graph API if you need any graph requirement in your application, its really good
See the example:
<html>
<head>
<script type="text/javascript" src="http://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load("visualization", "1", {packages:["piechart"]});
google.setOnLoadCallback(drawPieChart);
// google.load("visualization", "1", {packages:["barchart"]});
// google.setOnLoadCallback(drawBarChart);
function drawBarChart() {
// Create and populate the data table.
var data = new google.visualization.DataTable();
data.addColumn('string', 'Year');
data.addColumn('number', 'Sales');
data.addColumn('number', 'Expenses');
data.addColumn('number', 'Expenses1');
data.addColumn('number', 'Expenses2');
data.addColumn('number', 'Expenses3');
data.addColumn('number', 'Expenses4');
data.addColumn('number', 'Expenses5');
data.addColumn('number', 'Expenses6');
data.addColumn('number', 'Expenses7');
data.addColumn('number', 'Expenses8');
data.addColumn('number', 'Expenses9');
data.addRows(1);
data.setValue(0, 0, '');
data.setValue(0, 1, 1000);
data.setValue(0, 2, 400);
data.setValue(0, 3, 700);
data.setValue(0, 4, 40);
data.setValue(0, 5, 90);
data.setValue(0, 6, 480);
data.setValue(0, 7, 120);
data.setValue(0, 8, 100);
data.setValue(0, 9, 400);
data.setValue(0, 10, 200);
data.setValue(0, 11, 100);
new google.visualization.BarChart(document.getElementById('chart_div')).
draw(data, {width: 600, height: 440, is3D: true});
}
function drawPieChart() {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Expense Item');
data.addColumn('number', 'Expense');
data.addRows(8);
data.setValue(0, 0, 'Food');
data.setValue(0, 1, 11);
data.setValue(1, 0, 'Drinks');
data.setValue(1, 1, 2);
data.setValue(2, 0, 'Cinima');
data.setValue(2, 1, 2);
data.setValue(3, 0, 'party');
data.setValue(3, 1, 2);
data.setValue(4, 0, 'smoke');
data.setValue(4, 1, 7);
data.setValue(5, 0, 'smoke2');
data.setValue(5, 1, 7);
data.setValue(6, 0, 'smoke3');
data.setValue(6, 1, 7);
new google.visualization.PieChart(document.getElementById('chart_div')).
draw(data,{width: 600, height: 440, is3D: true});

Hi,
I want "Enter" Key press count fro .doc file. I am using ASCII value of "Enter" Key . But How can I find using stramreader while reading file.
Or any other Solution for that?
Thanks,
sjs

Well, it doesn't seems to be related to Asp.net.
I think C# forum will be more suitable for this question.
Anyways, streamReader may not work for this.
Read your word file text using Microsoft Word Object library,
and get the text in the string. After that you can easily find
"\r\n" characters in your text.
