the point is this:
As soons as the usercontrol ddl has changed it selectedindex the webpage should call a method to fill a Gridview which is outside of the usercontrol but in the page.
So if I remove the this.SelectedIndexChanged(sender,e); How can I fill the gridview autoside the ussercontrol with data?
|

This is what i'd do.
Forget about the code behind of the UserControl, make that Dropdown public in the usercontrol class and on the main aspx add the handler, (Page_Init, Page_Load):
private void Page_Load()
{
(yourusercontrol).(YourDropdownInUserControlId).SelectedIndexChanged += new EventHandler(s_SelectedIndexChanged);
}
private void s_SelectedIndexChanged(object sender, EventArgs)
{
}
Hope this works for you

Yeah,
this even works better!
This component is used over several pages in the system and only in 1 page it should do OnSelectionChangedIndex event. So the other pages have no interference with this.
COOL and many thanx

FOUND IT
just remove
//if (this.SelectedIndexChanged != null)
// this.SelectedIndexChanged += new EventHandler(this.DDL_Osic);
in the page_init in the user control. That was the devil that bit me this afternoon!
thanx for your input.

How can I quit completely from master page. End all sessions and go back to login page
Sessio.abandon() or Session.Clear seem not working
|
|
|
|
|
Hi,
Use Session.Remove("SessionVariable")
and check on master page load, if session is nothing then redirect your
login page

Fine Fine . What I did was to set a logout immagebutton to have a postback Url to be
"master page" and at the same time code click event to abandon session. I have noticed that
it did not recognize the coded click event but the postback. so it works after removing postback Url, but i think
such like confusions Microsoft should address instead of using common sense.

Hi,
some time i get this error :
Exception: System.ArgumentException: Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" %>

Can I suggest that if you take the advice already given, you make sure you fully understand its implications. There are security considerations here.

Hi,
I have a formview that uses a sqldatasource.
In the insert item template of the formview I have a file upload control that the user uses to upload an image to the database.
Then on the click event of the insert button I take the image and push it over to a byte array so that I can insert it into the database.
Then I want to update the insert sqlparameter with the byte array to be saved to the database.
The problem that I'm facing is that the column type in the database table is that of image, but when i try to set the sqltype of the insert parameter there is no image option under the TypeCode enum.
I can't insert the image as string nor as object cause it gives me an sqlexcpetion of converting from string to image type. The error is as follow : "Operand type clash: nvarchar is incompatible with image"
Any ideas on how to get this working?
Thanks in advance

images are binary type so you can do this by binary format

If I understand what you are asking... What you would need to do is:
1) Add a class library project to your solution
2) Move your classes from app_code to the class library project
3) Add a reference to the class library to your website
4) Add a reference to the namespace to the web.config so you don't have to add a using to every page
<page>
<namespaces>
<add namespace="MyDll" />
..it may take some debugging but this will get you most of the way there.
Regards,
Jeff

I have a series of dropdownlists outside the datagrid control. I'm looking for a tutorial or a point in the right direction to learning how to filter the datagrid with these controls.
If anyone knows a good place to start let me know, its much appreciated.
|
|
|
|
|
please describe your question in detail. what exactly do u need.
|
|

I'm looking for a way to drilldown i think it is the datagrid.For instance
When the page loads the default dataset with all the info is retrieved.
then the user can filter the data using dropdowns. But they can search between parameters eg. id > 34 id <544
|
|
|
|
|
when you retrieve data from database assign that datatable to default view and then filter with prarameter you want and then bind it with grid
