MessageString method is not giving action Width [modified]

Hi all,

I using MessageString method to calculate the string width. It is not giving the proper String Width.

Eg:
Font = "Arial 8.25";
Font.Style = Regular;
string1 = "1234567890123456789012345678901234567890123456789012345678901"

If you place this string to the label/TextBox. The actual width is 368px.
But when i use graphics.MeasureString method it gives 387.9978.

Is there any other method is available to calculate the string / what's the problem in this method.

Some article says, Sometimes MeasureString method will give improper values.
Is it true?

Please tell me if anybody knows...

Thanks.

Thanks & Regards
Kumaran

MeasureString actuall gives pixel representation of Actual Graphics Text string. It will be working when you are using a canvas to DrawString. Browser text size is not proper for this. I think the actual pixed depends on each browser.

So very little help you have other than trial - error method to determine the size of the textbox.

Love to see more replies if there is any alternative. Rose | [Rose]

You cannot Hide URL bar in IE7 and above
The same is also applicable to Firebox, Opera, Chrome, etc

Standard window.Open doesnt allow to hide your url. There is I think no support to hiding address in IE 7 or later. Cry | :((

You can not access Session object in Javascript as it is a Server object.

Here [^]is a nice article explaining how to write client side variables in ASP.Net

If you are trying to access lblLoginId.Text from client side, then what is need of session over here. You can try just using reading the ClientID of that control.

You can't Directly Access Session Variable from javascript. You can store it in a hiddenField and then can access from Client Side.

Leave it as Runat="Server"

Then

var HiddenFieldID="<%=hdnField.ClientID%>";
 var HiddenFieldValue=document.getElementById(HiddenFieldID).value;

There are Two ways

1. Using Classic Asp Tag to fetch the Session Variable

var cal = <%= Session("LoginID") %>

2. You can make a AJAX call to server to fetch the Value stored in Session Variable

no,no,no,no.......
I have seen this code in a couple of dozen posts and it NEVER works.
My situation
ASP .NET 3.5

C# code doc.aspx.cs

...
...
Session["UID"] = "1234";

Javascript doc.aspx

var uid = <%=Session("IUD")%> NO
var uid = '<%=Session("IUD")%>' NO
var uid = "<%=Session("IUD")%> NO
var uid = <%=Session([IUD"]%> NO
var uid = '<%=Session["IUD"]%>' NO
var uid = "<%=Session["IUD"]%>" NO

I think the code below would work but I'm not sure how to code the client side

C# code

HiddenField hUID.value = Session["UID"];

Javascript

????????????????

I'm pretty frustrated after several hours of trying to get this to work. A working example of code would be HIGHLY appreciated.

Thanks,

hiding the blinking cursor

I want to hide the cursor or make the blinking cursor stop blinking in the asp.net textbox. Is that possible??

Re: hiding the blinking cursor

Aman Bhullar20-Jul-09 3:31

You cannot hide the cursor. If you have set the ReadOnly=True then it will not not let user write anything. But cursor blinking will appear by default. Alternatively you can set the property TabStop=False. Then cursor will not appear by default in Rich text Box. But if you click in the Rich Text Box the cursor wil blink. But it will not let user edit as you have set ReadOnly=True

no normal HTML input text cant do. Well, why not u use Span to do that, when user types in the document, just update the span. This way you can only do this, but I dont think it is a better option to do.

Otherwise you can hide cursor if the textbox is within a Flash object. Rose | [Rose]

As an improvement to this, you may want to wrap this javascript into a custom validator and include server side validation also.

Insert a Grid View in item Template of ListView view below code

The code is tested .

<asp:ListView ID="ListView1" runat="server" 
                onitemdatabound="ListView1_ItemDataBound1">
                <LayoutTemplate>
                    <table border="0" cellpadding="3" cellspacing="0" width="97%">
                        <tr class="lstheader">
                            <td width="15%">
                                Col one</td>
                            <td width="15%">
                                Grid Column</td>
                            
                        </tr>
                        <asp:PlaceHolder ID="itemPlaceholder" runat="server"></asp:PlaceHolder>
                    </table>
                </LayoutTemplate>
                <ItemTemplate>
                    <tr >
                        <td>
                            <asp:Label ID="lblDate" runat="server" Text='<%#Bind("DepartmentID") %>'></asp:Label>
                        </td>
                        <td>
                            <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
                            <Columns>
                            <asp:BoundField HeaderText="Department" DataField="Department" />
                            </Columns>
                            </asp:GridView>
                        </td>
                    </tr>
                </ItemTemplate>
                <AlternatingItemTemplate>
                    <tr >
                       <td>
                            <asp:Label ID="lblDate" runat="server" Text='<%#Bind("DepartmentID") %>'></asp:Label>
                        </td>
                        <td>
                            <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
                            <Columns>
                            <asp:BoundField HeaderText="Department" DataField="Department" />
                            </Columns>
                            </asp:GridView>
                        </td>
                    </tr>
                </AlternatingItemTemplate>
            </asp:ListView>

now firstly Bind the ListView Control as below

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            fillgrid();
            clsDepartment dpt = new clsDepartment();
            ListView1.DataSource = dpt.SelectAll();
            ListView1.DataBind();
        }

    }

Implement the ItemDataBound event of ListView and Find The Gridview. After Finding bind it

protected void ListView1_ItemDataBound1(object sender, ListViewItemEventArgs e)
   {
       if (e.Item.ItemType == ListViewItemType.DataItem)
       {
           GridView Grd = e.Item.FindControl("GridView1") as GridView;
           if (Grd != null)
           {
               clsDepartment dpt = new clsDepartment();
               Grd.DataSource = dpt.SelectAll();
               Grd.DataBind();
           }
       }
   }
