Hi,
I am using office XP and i want to read the contents of the Word or excel file into my aspx page.
I have tried by using Response.contenttyp but it shows a dialog box asking if i want to save or open the file.
I want to just read the contents of the the file no editing or manipulation of the data.
how can this be achived.
Thanks in Advance.

You can use template column in the grid with two labels to display 2 fields
use <br> to display it in other line
<asp:TemplateColumn HeaderText="F1 & F2" HeaderStyle-Wrap="false">
<HeaderStyle Width="15%"></HeaderStyle>
<ItemStyle Width="15%"></ItemStyle>
<ItemTemplate>
<asp:label runat="server" Visible="True" id="lblF1" Text='<%# DataBinder.Eval(Container.DataItem, "F1") %>'>
</asp:label> <br> <asp:label runat="server" Visible="True" id="lblF2" CssClass="default_text" Text='<%# DataBinder.Eval(Container.DataItem, "F2") %>'>
</asp:label>
</ItemTemplate>
</asp:TemplateColumn>

Hi..
I wrote the following code to count my website visitors:
(In the Global.asax)
protected static int m_ActiveUsers;
public static int ActiveUsers
{
get
{ return m_ActiveUsers;
}
}
protected void Application_Start(Object sender, EventArgs e)
{
Application.Lock();
m_ActiveUsers=0;
Application.UnLock();
}
protected void Session_Start(Object sender, EventArgs e)
{
Application.Lock();
++m_ActiveUsers;
Application.UnLock();
}
protected void Session_End(Object sender, EventArgs e)
{
Application.Lock();
--m_ActiveUsers;
Application.UnLock();
}
But the problem it doesnt give me the right number always.Some times this code tells me there is two visitors while there is no one except me.And some times it doesnt decrement the visitors count number when i exit.
Do any one know how to make a better way that wont be affected by application errors and will solve my problem?

The problem is because session_onEnd event will not be fired while you logged out of the application or closes the window. (on session end)
|
|
|
|
|
Thank you for your respond...
If this is true(closing the window by a user wont fire Session_onEnd event)what should i do?
1-Decrease the timeout attribute of the sessionstate in web.config file?.
2-Use another event handler(other than Session_End handler )?.

I have 2 textbox and 2 listbox.What I want is when I click on add button all the values of textbox and listbox should get displayed in DataGrid.Then I add a new Record and Datagrid should get refresh with the new record.It should not earse the pervious record.
Finally when I clicked on Save button I need to save all the rows of Datagrid into the Database.
Please help me.

Hi,
What you can do is to create a datatable and add the records to that table when you are click add new button. Bind the datagrid with that datatable and refresh it on clicking of add new. Finally on click of save save all the content of the datagrid to the database.

Hi varshavmane,
I had similar kind of job sometimes earlier. If you dont want a post back on clicking of the ADD button then problem arises. For that you have to add some 'hidden textboxes' to your form.When you click on the ADD button add a new row to the datagrid through javascript ,which is quite easy,and put newly added values to the new datagrid row as well as add your records to the hidden textboxes by comma(,) separator.The newly added row and its values will not be traced by the server, its only for show purpose.You can add as many records as you want.Now finally when you click on the SAVE button take the old records from the datagrid and new records from the hidden textboxes and save them to the database.
In this process you will have only one postback. Otherwise on every click on the ADD button(when creating new records) will cause a postback.

No actually I have to use viewstate as I dont have to display the data into datagrid but may need to modify the data.Then Tracing the record into the hidden textbox will be very difficult.
So please help me with Viewstate.
Thanks and Regards.

Ok then Apurba's idea is good.But keep the datatable to a session varible.Why are u using viewstate?Hope it will solve your problem.

Hi,
I respect your idea and Apurba's but actually problem with the session is that I will have to distore session when I exit that form so I dont want to use.
I have never used Viewstate so I want some help/code which stores all the texbox and listbox values in viewstate and how can I retrival the data from viewstate.
Thanks and regards.

Hi,
Thats not a problem you can use viewstate to store the datatable.

Hi,
Thanks for the reply.But can u please tell me the syntax of storing the datatable in viewstate.As when I dont use viewstate my datatable gets refresh and because of which I lose the pervious record.
Also how to retrive the values from viewstate for datatable.
I have not used viewstate so I need to try this.
Thanks and regards.

Hi,
It is quite simple. To put into viewstate you can use:
ViewState["daa"]=ds;
and to retrieve you can use:
DataSet s = new DataSet();<br />
s = (DataSet)ViewState["daa"];<br />
Response.Write(s.Tables[0].Rows[0][0].ToString());
Although here i have used dataset, same way you can use for datatable.

Hi,
I can do this for textbox and listbox values also???And if I use datatable then will how do I bind it with datagrid???
Thanks and Regards.
|
|

what i told is that first you create a datatable with all the columns which you require and then when you click add new button add a row to that datatable. And you can bind the datagrid with the datatable directly i.e dg.datasourse = datatable.

Fllowing is the code what I have used:
private void ibtnAdd_Click(object sender, System.Web.UI.ImageClickEventArgs e)
{
Classes.CChecklist cchecklist = new Classes.CChecklist();
dgChecklist.AutoGenerateColumns = true;
DataTable dt = new DataTable("CheckList");
int cnt;
if(lbISOClauseNo.Items.Count > 0 && lbISODesc.Items.Count > 0 && txtExpected.Text != "" && txtTimeAllocated.Text != "")
{
for(cnt = 0 ; cnt < lbISOClauseNo.Items.Count ; cnt++)
{
if(cnt == lbISOClauseNo.Items.Count -1)
{
htxtFISOClauseNo.Value += lbISOClauseNo.Items[cnt].Value;
htxtFISOClauseDesc.Value += lbISODesc.Items[cnt].Value;
}
else
{
htxtFISOClauseNo.Value += lbISOClauseNo.Items[cnt].Value + "," ;
htxtFISOClauseDesc.Value += lbISODesc.Items[cnt].Value + "," ;
}
}
htxtFExpected.Value = txtExpected.Text;
htxtFTimePlanned.Value = txtTimeAllocated.Text;
cnt = Int32.Parse(htxtFChecklistNo.Value);
cnt++;
htxtFChecklistNo.Value = cnt.ToString();
}
//Checklist No
DataColumn dc = new DataColumn();
dc = dt.Columns.Add("Checklist No",System.Type.GetType("System.Int32"));
dc.Caption = "checklist_no";
//ISO Clause No
dc = dt.Columns.Add("ISO Clause No",System.Type.GetType("System.String"));
dc.Caption = "checklist_isoclause";
//Activities
dc = dt.Columns.Add("Activities",System.Type.GetType("System.String"));
dc.Caption = "checklist_activities";
//Expected Evidence
dc = dt.Columns.Add("Expected",System.Type.GetType("System.String"));
dc.Caption = "checklist_expected";
//Time Planned
dc = dt.Columns.Add("Time Allocated",System.Type.GetType("System.String"));
dc.Caption = "checklist_timeplanned";
DataRow dr = dt.NewRow();
dr["Checklist No"] = htxtFChecklistNo.Value;
dr["ISO Clause No"] = htxtFISOClauseNo.Value;
dr["Activities"] = htxtFISOClauseDesc.Value;
dr["Expected"] = htxtFExpected.Value;
dr["Time Allocated"] = htxtFTimePlanned.Value;
dt.Rows.Add(dr);
//Bind Datatable with DataGrid
dgChecklist.DataSource = dt;
dgChecklist.DataBind();
//Clear all the textbox and listbox.
lbISOClauseNo.Items.Clear();
lbISODesc.Items.Clear();
txtExpected.Text = "";
txtTimeAllocated.Text = "";
htxtFExpected.Value = "";
htxtFISOClauseDesc.Value = "";
htxtFISOClauseNo.Value = "";
htxtFTimePlanned.Value = "";
}
Whenever I click on add button datatable gets created again and I lose my last record.So I am in problem.
Please tell me how do I handle this

what you do is when the add button is clicked then you check whether you are having the datatable in the viewstate. If yes then use that(datatable in viewstate) to add the new record and if the datatable is not present in the viewstate(it will happen when the add button is clicked for the first time) then create a new datatable and put it into the viewstate. Finally attach that datatable which is there in viewstate to the datagrid.
