Hi,
Just came back from weekend tour.
I think the problem was with SQL Query, I think the where clause was missing.
Thats great that you solved the problem.
Happy Coding...
Thanks,

Hi,
I am writing a Web control library which contains a control to display multiple address lines, it has a property 'Addresses' which is an 'ArrayList' containing multiple 'Address' class objects, this works fine in code and I can add/remove addresses in code but I would like to be able to add them in design view (Like ListviewItems), and have them entered like this:
<br />
<MyControlLibrary:MyControl runat="server" ID="MyControl1"><br />
<Address Line1="Test" Line2="Test" /><br />
<Address Line1="Test" Line2="Test" /><br />
</MyControlLibrary:MyControl><br />
I think I need to use the 'ParseChildren' property but I have tried various ways and nothing seems to work, could somebody point me in the right direction?
Thanks

You may need to specify a couple of attributes for the custom property of your control to support at design time: Editor, DesignerSerializationVisibility, PersistenceMode. I believe that you can find the sample code from the artiles posted here on CP using the search functionality. For more information, see Attributes and Design-Time Support[^]

Its a bit tough to determine from your post exactly what you are trying to accomplish. The way I interpret it, there are 3 approaches that you might consider, depending on your needs.
The easiest way would be to simply force a postback with the row data each time you need to add to the grid. Your pop-up dialog could populate hidden textboxes that contain the row's information, and then use client side script to submit. The downside to this is that it is a very poor user experience.
Another way would be to use the DOM and client scripting to dynamically control the table on the client side. An example of this approach, with client script can be found here[^]. If that one isn't to your liking, many others can be found on the web. There are two downsides that I see to this method. First, older browsers will not support it. Secondly, the client manipulations will not be sent to the server. You would need to come up with a means of tracking the client side changes so that you could parse them on a postback.
Yet another option would be to use an AJAX-enabled interface to process handle the requests on the server in a real-time manner without degrading the user experience. There are plenty of this approach on the web, such as this[^] one. It may also be worth your time to check into a third party control to make this easier for you. Again, there are many to choose from, such as this[^] one that I've randomly selected.
If I were implementing it, I would probably go with a blend of the second and third methods. I would perform client side manipulation to the table directly and fire off an async request to the server to track the changes at the same time. In my opinion, that would give the best user experience without having to resort to dirty tricks to "remember" the sequence of changes as they occur.
Hopefully, that provides enough help to get you started. Best of luck.

Hi,
I am new to .Net. I developed a web application in ASP.Net and C#. Here I included a reference to Acrobat COM dll. I actually want to remove the toolbars from the PDF Document. But when I try to run the application, it throws a runtime error "Access Denied". I tried to register the COM dll using:
"regsvr32 Interop.Acrobat.dll". But here the error message is that: "the dll was loaded but entry point was not found".
To deal with the error "Access denied", I included "<identity impersonate="True">" in the web.config file. This helps run the application only on the server. When I try to run the application form a client, it throws a "runtime error" or "Server eror".
Can anyone suggest me a solution. Either how to run the application on clients using identity impersonate="true" or a solution to the Acrobat COM object.
I am facing a tough time and any help would be really appreciated.
Thanks,
Awase.

Hi,
i have written following code
TextBox tb = new TextBox();
tb.Text = "ghjhgjh";
Label lbl = new Label();
lbl.Text = "Hello, World!";
lbl.Font.Bold = true;
Controls.Add(lbl);
Controls.Add(tb);
foreach (Control c in Controls)
Label1.Text += c.ToString() + " - " + c.ID + "
";
but on running i get the following exception --> Control 'ctl03' of type 'TextBox' must be placed inside a form tag with runat=server.
also please explain how to retain the view state of the text box.
|
|
|
|
|
On the HTML tab of the .aspx page you should see the <textbox> tags. Make sure that it is within the tags. I've had that happen before. Within the textbox you can do
<asp:textbox id="abc" runat="server" viewstateenabled="true/">
Hope that helps!

Hi,
adding within controls inside form tag is not under my control unless i use addat function.
Moreover pls help with retaining the view state .Many say that it should be added in the init ftion.But still doesnt work.Pls write a small snippet if possible because couldnt find a suitable link i require in net.
|
|
|
|
|
Go to the properties of the text box and make view state as true.
View state will be automatically saved.
Make sure That textbox is server control.
Go to html, make sure that is within tag and include runat = server
hope that helps

hi,
i have given this piece of code in page Load()
{ DDLSortBy=new DropDownList ();
DataSet ds=new DataSet ();
da.Fill(ds);
DDLSortBy.DataSource = ds.tables[0]
DDLSortBy.DataTextField = "EmpId";
DDLSortBy.DataValueField = "EmpId";
DDLSortBy.DataBind();
DDLSortBy.SelectedIndex = 0;
DDLSortBy .AutoPostBack = true;
DDLSortBy.SelectedIndexChanged += new System.EventHandler(DDLSortBy_SelectedIndexChanged);
plFrm.Controls.Add(DDLSortBy);
}
i am able to retain the value(view state) of the text box inspite of the DDL getting initialized each time on postback.I see no difference if initialize the controls on OnInit() function.
Then why many articles in net suggest us to dynamically add controls in init ftion() .

I think that it is because you add controls using Controls.add() on its own.
It may place the controls somewhere in the page that is not between form. Check that in the html generated through your browser.
Try using a placeholder where to add your controls and you will have no problems at all cycling through it getting controls infos.

+ Option 1: simply walk through the 4 radiobutton and do checking on the Checked property of each radiobutton.
+ Option 2: use the RadioButtonList control instead of seperate 4 controls, and the control supports a couple of properties SelectedXXX which can help you.
|
|
|
|
|
If it's a RadioButtonList you can use the SelectedItem property to find out which RadioButton is selected.
If you have 4 separate radio buttons you have to check them one by one to find out which one has radioButton.Checked = true;

but the problem is the scoreCardID 1 is getting measure data for scoreCardId 2 so I am not getting correct webchart for scorecardIds.
can someone help me how it could be fixed so that i can get correct web charts for my scorecard ID.
thanks

Hi there,
There are a couple of things come to mind:
+ The GetRecords seems not to return the result in the else part.
+ The GetRecords is used to populate the data source for the dlScChart datalist control, so you should not put your code to build its child control (the charting control) in this method. In this case, you might consider using the ItemCreated/ItemDataBound event of the datalist control.
+ The ScoreCardID value contained in the datasource bound to the parent control dlScHead, so if you want to get this value from the child datalist dlScChart, you need to get reference to the DataListItem object of the parent datalist dlScHead. Another option is that you can populate the datasource bound to the child datalist control in a way that it should contain ScoreCardID value. And you can easily access this field when you build the charting control.
