Hi man, since it is MS Access so you cannot use trigger; For this
situations the best solution is to write a trigger.
Alternatively, write a program in c#, that will do the necessary task.
Write the program in the Form Load event so that the checking will happen
every time when the application will run.
Also create a table in MS Access with three fields say AdvertisementId , StartDate, EndDate.
So what will happen is that, everytime the form will load,the StartDate will be checked with end date corresponding to the Advertisement Id.
If the StartDate < EndDate, just update the StartDate by 1(i.e. 1 day will be incremented).
When StartDate = EndDate, execute the delete operation.
But always do it in the Form Load event
Hope this helps

I will recommend you to maintain a validTillDate flag in the respective table column for various advertisements. In the page when you are going to show the advertisement, just check whether the validDate flag is greater than the current date or not. If it is then simply don't show the advertisement. Deleting data from the table is not recomended from the future perspective. Hope this helps.

You may have a table called "tblAdvertisement" where you are storing all advertisements. This is the table from which you are also showing advertisments in the page. Now add a seperate column (of datetime type) called "validTillDate" column. Whenever you are inserting any record in the "tblAdvertisement", put a "validTillDate" for the advertisement. "validTillDate" simply stores the date till the advertisement will be valid and active.
When you are going to show advertisments on the page, check all advertisements' "validTillDate" column pick only those advertisement whose "validTillDate" column value is less than or equal to the current date. It will be best if you can check it in the sql statement itself. Just checkout the sample sql query:
select * from tblAdvertisement where validTillDate <= getdate()
I think this explanation should be enough for you to get started. There is no link and url that I can give to you as there is more logic invloved than coding. In case of any issue, revert back to us.

Hi I am Chinmay , i am using telerik Rad controls in my projects.
Problem : -
I have two fields in telerik radgrid. one is a readonly textbox with datetime value . other is a editable RadDateTimePicker.
Requirement - Whenever I change/select a date from RadDateTimePicker it should check whether the selecteddatetime is greater than the value present in the readonly textbox and popup a window with a simple message . All this we have to achieve through javascript and the validation should takes place as soon as we select a new value from RadDateTimePicker
I tried with SelectedDateChanged event of RadDateTimePicker but I am unable to access the javascript method attached to this event.
Can you please help me and if possible can you please post a sample code to achieve the requirement.
Thanks in advance.

Below is the add and get cache methods; however, the get method doesn't return any value. I have insured that the key (sessionID) is valid when calling both. Can someone help?
public Object GetCacheItem(string key)
{
return HttpRuntime.Cache.Get(key);
}
public void AddCacheItem(string key, Object value)
{
HttpRuntime.Cache.Add(key, value, null, DateTime.Now.AddMinutes(20), Cache.NoSlidingExpiration,
CacheItemPriority.Default, null);
}
Thanks,
Steve

I only ever access the cache item like:
object sessionObj = HttpRuntime.Cache[key];
'Get' sounds like it would do the same but I'm not certain.

Of course.

Also, of course.
ASP.NET is just an engine for HTML and javascript. The end page does not care where the script came from . If you can't write your own AJAX, if you must let the toolkit do it for you, then you probably need to take some care not to stomp what it does with your script, that's the risk of using a black box. But, there's no reason you can't do it, and probably little chance you'll break anything.
Yadav Pramod wrote: and also tell me how do i add the usercontrol on a page.
The same way you always have. You're surely not playing with the AJAX toolkit prior to knowing how to define your own control ?

Solution for
OnCheckedChanged event of the radio button.
check with ClientScript.RegisterClientScriptBlock
e.g.[ some pseudo code]
public void ShowMessage(string input) {
string strScript = String.Empty;
strScript =@"<script language=javascript> ";
strScript = strScript + "alert('"+input+"')";
strScript = strScript + @"</script>";
RegisterClientScriptBlock("clientScript", strScript);
}
protected void rdButton_OnCheckedChanged(object sender, EventArgs e)
{
ShowMessage("Niladri Showed a way to solve the problem");
}
Check for the next part, add <pre><script language="javascript" type="text/javascript"></pre>
If not you are making any mistake it is guarented to work.
Vote please

OnCheckedChanged is a server side event and fires only when AutoPostBack is turned on. So hooking a JS function from here is pointless. I guess you want to call a JS function when someone clicks on the CheckBox, right?
Use the Attributes[^] property to add a onClick attribute. Something like
YourCheckBox.Attributes.Add("onClick","JsFunction();")
Do this on the page load, so that your checkbox renders with this attribute and JsFunction() will get called when user clicks on the checkbox.

hello
Can anybody tell me how to bind morethan two tables to grid view
I want to add items from one table and
can add year and month value from another tables

Are you talking about tables in a database or tables in a DataSet?
In the database you can join the tables together use SQL to produce a single result set.

First of all the question itself is not clear.
Case I
Assuming that it is database table
Solution
Produce a single resultset by aplying join or any other condition based on your demand
Case II
Assuming it is DataTable
Solution
Create a custom datatable table that will have all the fields.
Fill the table programatically and then make it as the datasource of your grid view
e.g. [ Some rough pseudo code]
Datatable dt1 = new Datatable();
dt1.Columns.Add(Col1);
dt1.Columns.Add(Col2);
dt1.Rows.Add("Val1","Val2");
dt1.Rows.Add("Val3","Val4");
Datatable dt2 = new Datatable();
dt2.Columns.Add(Year);
dt2.Columns.Add(Month);
dt2.Rows.Add("2001","Jan");
dt2.Rows.Add("2002","Feb");
Datatable dtFinal = new Datatable();
dtFinal .Columns.Add(Col1);
dtFinal .Columns.Add(Col2);
dtFinal .Columns.Add(Year);
dtFinal .Columns.Add(Month);
dtFinal .Rows.Add("Val1","Val2","2001","Jan");
dtFinal .Rows.Add("Val3","Val4","2002","Feb");
myDatagrid.DataSource = dtFinal;
myDatagrid.DataBind();
Hope this helps

If your both datatables follow same structure, you can use DataTable.Merge[^]. But it looks like you have different structure. Obvious method would be to get a single data structure which has all the data required for binding.
