Images on server.

Hi,
have just tryed this but it seems not to work? where is it wrong?
if(st5.SelectedValue=="Bad Mood")
{
st5.SelectedValue="Images/sad.gif";}
else if(st5.SelectedValue=="Good Mood")
{
st5.SelectedValue="Images/laughing.gif";}
And this is the error I'm getting:
Specified argument was out of the range of valid values. Parameter
name: Images/laughing.gif.
Thanks
st5 is your RadioButtonList
st5=(System.Web.UI.WebControls.RadioButtonList)e.Item.Cells[1].FindControl("rblmood");
so, what do you want to get using
st5.SelectedValue="Images/laughing.gif";
?

Sorry I've been away for some time. Yes st5 is my RadioButtonList. I
want the image laughing to come along when good mood is selected.
that's: st5.SelectedValue="Images/laughing.gif";
Thanks.- Hide quoted text -

1) SelectedValue is a read-only property and you cannot assign a value
using st5.SelectedValue=...

2) st5 is a RadioButtonList and it cannot be equal to the "Images/
laughing.gif"- Hide quoted text -

Is that the reason I'm getting this error:

Wait, I think I made a mistake telling that it's a read-only:

MSDN: "Gets the value of the selected item in the list control, or
selects the item in the list control that contains the specified
value."
Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

Sorry.

The error message "Specified argument was out of the range of valid
values. Parameter name: Images/laughing.gif" means that there is no
such value "Images/laughing.gif".

Mark, no problem, actually I don't know why I thought it's a read-only
property. Maybe I had never used that before.

Rcoco,

You should understand conceptually what you are doing, rather than
following copy-and-paste code blindly. Your program is working as you
designed it, and not as you might think it should work.

You have to understand what the "out of the range of valid values"
means. This means that st5 (a RadioButtonList) has no value named
"Images/laughing.gif". I cannot answer, how you can make it working,
because I don't know how it should work. You used the following code
before:

imgDaily.ImageUrl = "imgbm"

Now, you are using

st5.SelectedValue = "..."

Why did you change this and what is the logic behind?

I thought, you wanted to change an image. Using st5.SelectedValue you
will change selection (a point) of the radio button.

If you definitely need to change the selected item in the
RadioButtonList you should know what values it has. Look in your code
where you bind the values (dataset, whatever) to this control.

P.S.

If you don't get what I mean, once again post the complete source code
of your radio button list which is not working as expected (aspx part
and code-behind) and explain how it should work step by step.

This is how the code looks like:

private void Page_Load(object sender, System.EventArgs e)
{
if (! IsPostBack)
{
Fill();
Bind();
}
}
System.Web.UI.WebControls.RadioButtonList st5=new
System.Web.UI.WebControls.RadioButtonList();
st5=(System.Web.UI.WebControls.RadioButtonList)e.Item.Cells[1].FindControl("rblmood");
SqlCommand myCommand=new SqlCommand();
myCommand.Connection=con;
myCommand.CommandText="insert into DashBoard (MoodToday) values
(@MoodToday)";
myCommand.Parameters.Add(new
SqlParameter("@MoodToday",SqlDbType.Text));
myCommand.Parameters["@MoodToday"].Value=st5.SelectedValue;
if(st5.SelectedValue=="Bad Mood")
{
st5.SelectedValue="images/sad.gif";
}
else if(st5.SelectedValue=="Good Mood")
{
st5.SelectedValue="images/laughing.gif";
}
Fill();
InsertEmpty();
Bind();
This is the HTML part
<ItemTemplate>
<asp:Label id=Label2 runat="server" Width="104px" text='<%#
DataBinder.Eval(Container,"DataItem.MoodToday")%>'>Label</asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:RadioButtonList id="rblmood" runat="server" Width="104px">
<asp:ListItem Value="Good Mood">Good Mood</asp:ListItem>
<asp:ListItem Value="Bad Mood">Bad Mood</asp:ListItem>
</asp:RadioButtonList>
<asp:Image id="imggm" runat="server" ImageUrl="../Images/laughing.gif"
ImageAlign="Right"></asp:Image>
<asp:Image id="imgbm" runat="server" ImageUrl="../Images/sad.gif"
ImageAlign="Right"></asp:Image>
</EditItemTemplate>
Thanks

rcoco · Apr 10, 2007

This how it is supposed to work.
When a user selects RadioButton GoodMood the image imggm(laughing.gif)
should be selected as well.
and if BadMood is selected Image imgbm it should be imgbm(sad.gif).
Thanks.

What do you mean by "the image should be selected"?

Assuming the code is working properly, except a "selection" of the
image, you should change the if..else block

Image imggm = (Image)e.Item.Cells[1].FindControl("imggm");
Image imgbm = (Image)e.Item.Cells[1].FindControl("imgbm");

if (st5.SelectedValue == "Bad Mood")
{
imgbm.BorderWidth = Unit.Pixel(2);
} else {
imggm.BorderWidth = Unit.Pixel(2);
}

This code put a border around the first image if st5.SelectedValue !=
"Bad Mood", otherwise, the second image will be bordered. This is how
I understand your "selection".

Hope, it helps.

Hi,
Lets say this is any of the image: ))(( .
What I'm trying is to get the out put look like: ))(( Good Mood
after inserting data In a datagrid cell for right now after inserting
data I only get Good Mood. with out the Image.
As You see in the html code The Image and RadioButtonList are in
EditItemTemplate:

<EditItemTemplate>
<asp:RadioButtonList id="rblmood" runat="server" Width="112px">
<asp:ListItem Value="Good Mood">Good Mood</asp:ListItem>
<asp:ListItem Value="Bad Mood">Bad Mood</asp:ListItem>
</asp:RadioButtonList>
<asp:Image id="imggm" runat="server" ImageUrl="../Images/
laughing.gif"></asp:Image>
<asp:Image id="imgbm" runat="server" ImageUrl="../Images/sad.gif"></
asp:Image>
</EditItemTemplate>

Thanks

I don't get your reply.

What problem do you have? An image sad.gif is not shown? If yes, when
the problem occurs, when page is initially loaded or after you changed
a selection of the RadioButtonList?

It's supposed to work like this When on selection of RadioButton from
RadioButtonList and inserts data that is when Image should be visible
in datagrid column. For example if Bad Mood is selected and inserted
into database, image sad.gif should be visible in datagrid column:
))(( Bad Mood (consider ))(( to be image sad.gif).
This should be after one has inserted data.

Alexey,
What if I Change the images from EditItemTemplate to ItemTemplate
wouldn't it be better? As in I make the images invisible and When I
edit my data in datagrid one of the images becomes visible can tha
work?

But then I think it has nothing to do with the EditItemTemplate

If I understand you correct, you have to change

<EditItemTemplate>
<asp:RadioButtonList id="rblmood" runat="server" Width="104px">
<asp:ListItem Value="Good Mood">Good Mood</asp:ListItem>
<asp:ListItem Value="Bad Mood">Bad Mood</asp:ListItem>
</asp:RadioButtonList>
<asp:Image id="imggm" runat="server" ImageUrl="../Images/
laughing.gif"
ImageAlign="Right"></asp:Image>
<asp:Image id="imgbm" runat="server" ImageUrl="../Images/sad.gif"
ImageAlign="Right"></asp:Image>
</EditItemTemplate>

to:

<EditItemTemplate>
<asp:RadioButtonList id="rblmood" runat="server" Width="104px">
<asp:ListItem Value="Good Mood">Good Mood</asp:ListItem>
<asp:ListItem Value="Bad Mood">Bad Mood</asp:ListItem>
</asp:RadioButtonList>
</EditItemTemplate>

and delete the following part

if(st5.SelectedValue=="Bad Mood")
{
st5.SelectedValue="images/sad.gif";
}
else if(st5.SelectedValue=="Good Mood")
{
st5.SelectedValue="images/laughing.gif";
}

The EditItemTemplate used to edit a current record in the datagrid.

That is:

1) you bind your grid to the database
2) you show EditItemTemplate with your radio buttons
3) you post the web form back to the server
4) you find a selected value of the radio button

<-- I guess, you are this step

5) you save the selected value to a database
6) you bind your grid to the database again

So, you should update the database (step #5) and repeat step #1 which
is the same to step #6

You are right, I forgot to mention.

You can have an additional column in your datagrid, where you will
show your "mood".

I'm not sure what exactly you kept in the database as a "mood" value:
a string, or numeric value?

If you kept a string in the database ("sad", or "laughing")

the code will be

<asp:TemplateColumn>
<ItemTemplate>
<asp:Image Runat="server" ID="Image1" ImageUrl='<%# "/Images/" +
DataBinder.Eval(Container.DataItem, "Mood") + ".gif" %>'/>
</ItemTemplate>
</asp:TemplateColumn>

where Mood is a name of your datasource field

If you save your mood as a numeric value (e.g. "0" - for sad, "1" -
for "laughing")

<asp:TemplateColumn>
<ItemTemplate>
<asp:Image Runat="server" ID="Image1" ImageUrl='<%# "/Images/" +
((int)DataBinder.Eval(Container.DataItem, "Mood") == 0 ? "sad" :
"laughing") + ".gif" %>'/>
</ItemTemplate>
</asp:TemplateColumn>
