+ 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;

Hi,
I am plotting a dynamic/multiple web chart objects based on the data that i query from database.
below are my aspx code,

-----------------------
For i = 0 To dlScHead.Items.Count - 1
dlScHead.Items(i).FindControl("Placeholder1").Controls.Add(chart)
Next
-----------------------
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.

Hi there,
I'd be really grateful if you could please edit my code and show me as i am really having hard time. the next thing that i did was followed your way and now i am just getting able to populate charts with no data but every first measure_id is missing for each scorecard ID.
I did sumthing like this.
aspx
=====
<asp:repeater id="myRepeater" runat="server" OnItemDataBound="myRepeater_ItemDataBound">
<ItemTemplate>
<h3><%#DataBinder.Eval(Container.DataItem, "ScoreCardId")%></h3>

<h4><%#DataBinder.Eval(Container.DataItem,"Measure_ID")%></h4>

You need to specify the DataMember property before calling the DataBind method:
nestedRepeater.DataSource = subDs
nestedRepeater.DataMember = subDs.Tables(0).TableName
nestedRepeater.DataBind()
'nestedRepeater.DataMember = subDs.Tables(0).TableName

Hi,
yeah i did try that earlier but it skips every first measureid of a scorecardId dont know why.

Having a look at this code, I can see that you are creating the chart control inside the fist for statement, but you are adding it to the Controls collection in the second for statement. It means, in the second loop you are using the same chart object to add to the Controls collection. However, there's one important thing that you may not know is that each control only has one parent control, it also means when you add a control to the Controls collection of the new parent control, it will remove the control out of the Controls collection of the current parent control. And as a result of that, the chart control only exists in the last RepeaterItem of the nestedRepeater.
So to work around this problem, you might consider creating the chart control in the second for statement, another option is to create a handler for the ItemDataBound event of the nestedRepeater.

hi all,
i have problem with javascript. i wrote a function, when i use
|
|
|
|
|
Looks like you are a bit confused between the client side event onclick with the server side event with the same name. If you are using the ASP.NET 2.0, you can check out the OnClientClick event of the button.
|
|
|
|
|
The error was caused by your compiler looking for startClock function in the code-behind file.
If your button is an ASP button, the OnClick is meant to call server-side function (ie. .Net functions). You should use the OnClientClick instead to call your javascript function.

tanks for your replies,
i am confused because i am very new in asp.net applications . the point of i couldnt understand why this code runs body onload event but returns error on button click event . when i click the button i will start a client side timer and show this to user like a kronometer. also i have something to do on button click event . if i use input(http) button could i use javascript code and click event together?
my english isnt ok so i cant explain what i mean clearly . i hope you can understand

Yes, you can call both Javascript function AND the ASP.Net click event postback using an input button.
If you are using an input button (not ASP.Net Button), then just add <input onclick="return functionName();>"
By returning the value of the function's result, you can choose to return true in your function if you want the input to do postback to the server or false if you don't.

Hi all,
I am passing values from my datagrid to client side javascript function. In that some of the values contains apostrophes or quotes, which is creating error.I guess, this is because of values passed to browser are in ' ' quotes, and it encounter an apostrophes or quotes, that creates an error.
Anybody have some solution of this problem?
Please let me know.
Thank you very much,
NIKI

Try running the values through System.Web.HttpUtility.HtmlEncode()
|
|
|
|
|
That doesn't affect the apostrophes at all. Apostrophes has no special meaning in HTML, so they are not changed by the HtmlEncode method.

I have the same problem too.

Encode the string correctly to be a string value in Javascript:
theString = theString.Replace("\\", "\\\\").Replace("'", "\\'");

b { font-weight: normal; }

Hi Guffa,
I have a line in javascript function like this:
function myfunction(value1)
{
document.GetElementById('td').innertext=value1;
}
how can i parse the value1 field which contain apostrophes, such a way that it will not create problem while passing to the javascript function from server datagrid. and also, i dont want to eliminate apostrophes from the output on client side.
Thanks,
NIKI

You do as I showed when creating the code that calls that function.

b { font-weight: normal; }

Thank you very much Guffa,
The logic is perfectly working with my code.
Thank you very much.
I really appreciate your help.
