I have a problem loggingout of application
when i press back button(in browser) the pages are reappearing
i want to stop this
is there any code
please help me............urgent
thanks in advance
|
|
|
|
|
if u r using a link button jst redirect to the page on which u want to go...i didnt got u exactly...
|
|
|
|
|
yes, i know that
but i want to clear the history
so that logout action would be succesful
|
|
|
|
|
if you want to clear the history you can use history.forward(); in your java script
|
|
|
|
|
If u r logging out properly then even if u can see pages by pressing back button, u won't be able to access it. Means u can't click any button or like that, it'll again ask for Login.

I have a Grid view using ObjectDataSource. I add the values of a column and display it in a label in DataBound event. when i move to next page the value in label should change but its showing the values of first page only.
Any help will be appreciated!
Thanks in advance

I think you haven't considered the page number while assigning value in row data bound so that you are asssigning value to label from the same object.Can you check that? 
|
|
|
|
|
When i click on Next Page, GridView RowDataBound event and Databound event will be called up. Label is getting right value but when it displays, it displays the previous value. Dono know howz it happening.

This is my code. When i click on next page right value get stored in label but display the value of previous page. Dono know its happening at the tiem of rendering or what?
I have removed my code from DataBoundEvent to Selected event of ObjectDataSource. Still the problem is same.

Try calling gvCardFeesRReport.DataBind() after setting the Page Index property of the gridview in your RowCommand event handler.
Do like this:
gvCardFeesRReport.PageIndex = 0;
gvCardFeesRReport.DataBind();
Cheers!

1. Why not do your pagination in the PageIndex_Changing event of the gridview rather than in the RowCommand event?
2. Where you have:
for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
{
String feeID = ds.Tables[0].Rows[i]["TRANTYPEID"].ToString();
Decimal feeAmount = Convert.ToDecimal(ds.Tables[0].Rows[i]["TRANSACTIONAMOUNT"]);
you can substitute with:
int pageOffset = 10 * gvCardFeesRReport.PageIndex;
for (int i = 0; i < gvCardFeesRReport.Rows.Count - 1; i++)
{
String feeID = ds.Tables[0].Rows[i + pageOffset]["TRANTYPEID"].ToString();
Decimal feeAmount = Convert.ToDecimal(ds.Tables[0].Rows[i + pageOffset]["TRANSACTIONAMOUNT"]);
3. If all these don't work, try populating your gridview programmatically to achieve more control over your data.
Hope this helps

I am not able to add rows n values to data gridview programmatically(without binding to datasource)..I think the problem is because the rows are assigned 'databound' property...Any alternative for 'databound' so that i can add values programmatically?

Hi,
if (FileUpload1.HasFile == true)
{
FileUpload1.SaveAs(Server.MapPath("~/AdminSection/Attachment/Emp/" + FileUpload1.FileName.ToString()));
}
If file is not blank, then this code work fine.
but if the file is blank then it doesn't.
Is there any Solution for this.
or tell me how to check whether file (File can be of any type) is blank or not.
Thanx.

Check FileUpload1.FileBytes.Length or FileUpload1.FileContent.Length for validating the file size.
