<OBJECT id="combo" style="WIDTH: 156px; HEIGHT: 24px" height="24" width="156" classid="clsid:8BD21D30-EC42-11CE-9E0D-00AA006002F3"

Assuming that you have have developed a proper custom control
now you can add events to it take a look at this example

Hi friends,
I got problem when i redirects from one http page to other https page then , my page from which i am redirecting is reloads first time.
can any one tell me why this is happening ?
i have simple anchor tag like <a href="https://....>Registration</a>
when i click on that my page which contains that anchor tag is reloaded.
is it necessary to set "requireSSL="True"" in web.config for this type of redirection in same application.
Thanks.

Your anchor tag is not visible. Modify your message and use ignore HTML tags option.

Hi Everyone,
I would like to know how am I able to access the templateField I created in my GridView, which I set it to invisible initially, to make it visible when user click on the EDIT button and subsequently update into the database for the selected value.
|
|
|
|
|
Try with Javascript for making the combo box as visible when the user clicks edit button in the Grid view.

Satips.

Hi,
When You create template field for edit, make it as "edit item template".
No need to make invisible.
An "edit item template" will automatically display when you press edit link.

Thank you so much for your help. I am quite new to asp.net so i may be asking some silly questions. Can I ask you another question? When I enter editing mode, how do i set the value of the combobox to the record in my database. If the user changes it, how do get the value of the combobox and update it back to the database ?

hi,
For make editing using gridview you should do following things.
1. Enable AutogenerateEditButton property of 'gridview' to true
2. Add Dropdownlist in to 'Item template' of 'gridview'
///
<asp:DropDownList ID="DropDownList1" runat="server" Width="126px"
DataSourceID="SqlDataSource1" DataTextField="Field2"
DataValueField="Field1" SelectedValue='<%# Bind("Field1") %>'>
</asp:DropDownList>
///
3. Add Dropdownlist in to 'Edit item template' of 'gridview'
/////
<asp:DropDownList ID="DropDownList2" runat="server" Width="126px"
DataSourceID="SqlDataSource1" DataTextField="Field2"
DataValueField="Field1" SelectedValue='<%# Bind("Field1") %>'>
</asp:DropDownList>
/////
4. Add an sqldatasource to your form
////
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="server=yourserver;Integrated Security=yes;Database=YourDatabase"
SelectCommand="SELECT [field1], [field2] FROM [YourTable]"></asp:SqlDataSource >
////
Now it will show the data in your table.
4. To update the data...
You should specify an "UpdateCommand" to the sqldatasource of your "gridview".
ex: UpdateCommand="UPDATE [YourTable] SET [field1]=@field1 WHERE [field2]=@field2"
Try...............

HI,
Thank you so much for your wonderful reply. I still can't get it to work..The user changes the category from the category Combobox and I need it to update the selected category to the database. The rest of the fields in the editing mode are textboxes, so there are no problem with updating them. The bind command doesn't work as it says categoryName can't be found? Without the bind and inputing @categoryname doesn't reflect the selected comboxItem...I tried controlParameter under the updateParameter but it doesn't work as well...I am so lost....
|
|
|
|
|
Hi,
In your select command of "sqldatasource" you should give that field name.

hi AaronNeo,
Do you know one thing.. The controls inside "Edit item template field"
are same as other controls.So we can do whatever we like, on it.
So just resize it in design mode itself(from inside the "Edit item template field").

Your code is ripe for SQL injection attacks. Define 'doesn't work'. What does it do ? Can you pinpoint the bit that doesn't work ? No-one is going to read all of this...

I just want to know that I have already a web application. I want to use ajax in one of my web forms.
I installed AJAX in my machine. Now to use ajax in my web application should I create a new web site in VS 2005 and select ASP.Net AJAX - Enabled Site
and then copy my all the web forms and datasets from my existing web application to this new AJAX application to be able to use AJAX.
I am wondering if there is any other way to use AJAX in already existing web application.
Thanks in advance.

You cannot modify a collection and enumerate it at the same time. In other words, if you are counting a stack of coins, and someone takes some coins from the counted stack, you have to start your count again.
You can do the following to solve your problem:
1. Search for all the AplicacionID's in one table that don't belong in the other table.
2. Extract the AplicacionID from each row found and place it in an AplicationID collection.
3. Enumerate through the AplicacionID collection, search for the AplicationID in the target table, and, if the AplicacionID is found, delete the row or rows.
