I am using a temporary data show in gridview. I want delete the particular row when click the button. i am using the (GridView2_RowDeleting) event. I write below this code.
protected void GridView2_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
DataTable dt = new DataTable();
Session["dt"] = dt;
dt.Rows.RemoveAt(e.RowIndex);
GridView2.DataSource = ((DataTable)Session["dt"]).DefaultView;
GridView2.DataBind();
}

(There is no row at position 0.)

Your are creating new DataTable thats means your dataTable is null.

Yes, I am creating a New data table. I have two buttons. First is Add, Second is Save. When Click the Add button, Data Temporary show in GridView.
When Click the Save Button, Data Save in Database.

You create a new DataTable object. By default, it doesn't have any rows of data in it.
You then try and delete the row at postion 0. There is no row at position 0, so an OutOfRangeException is raised.

You're not making any sense.
I've told you what the problem is with your code. If you don't understand, you're probably beyond help.

First you have to copy data from your object datatable to temporary datatable

for this purpose use the application state variable and on every session start of a user, increment the application variable and decrement it on every session end. This might solve your problem.
When you fail to plan, you are planning to fail.

No this won't. This will give the number of users visiting the site, not page hits

Assign a unique id for each page and store the details in DB. When page loads, increment the entry. If you can store the IP address of the specified user, you can avoid re-inserting the same record when user refreshes the page.

You have declare flag=0 and thats why the first condition always executes.
You have to also set flag in if condtion
something like this.
int flag;
if(txtdate.text=="")
flag=1;
else
flag=0;
best regard

Then you can find the exact problem.

}
Is your control goes inside all these conditions when you checked with break points ? Try to explain clearly what happened when debugged ?

hello
when i checked with breakpoint that time control is go inside only first two conditions.
when i check 3 rd condition that time control is go again first condition not third condition.
and so date is not searched.

That means that time flag is 0 so that the first condition executes

When you checked the third condition, what was this dtpFrom.Text returning ? I guess it's a blank value, right ?
|
|
|
|
|
hello
no its not blank value .it have whatever selected date.

I think u need to update ur if conditions ...
What is ur requirement, what i could percieve is u have u have one ddList and two textboxes now tell me what u want.
|
|
|
|
|
I guess u can write ur if condition in another format like..
if(!(dropdown1.SelectedItem.Value == "")
{
}
else if (!(dtFrom.Text==""))
{
}
else if (!(txtSecurityCode.Text ==""))
{
}
