Hi,
How you are calling this function?
You can pass TextBox1.ClientId to the function.
Then use that passed variable inside getElementById.

To succeed, we must first believe that we can.

Ok Do this

In your page load

Button1.Attributes.Add("onclick", "javascript:ere('" & TextBox1.ClientID & "')")

and
function ere(txt)
{
alert(document.getElementById(txt).value);
}

dont forget to give runat=server to your button.

To succeed, we must first believe that we can.

Hi,

FYI, View the Default.aspx page in browser, and View the source (rigth click on page and select View Source). Then you try to locate the ID of your text box. After rendering, the client ID may not be same as the server control ID that you have supplied while developing the page.

So you have required to pass the ClientID of the text box to your Javascript method.

Try Call JavaScript method like, onclick="javascript:function();"

Hi,

C# Code

Any Event handler((eg)button click) --> onclick="JavaScript:SomeFunction('" + tbox1.ClientID + "')";

Javascript code:

function SomeFunction(tboxID)
{
tboxID.Value="Test";
}

This will assign the string "Test" to TextBox tbox1. This will works fine. Let me know, if you find any problem.

Regards,

I am using Template Fields in which i had taken ImageButton for edit ,Update adn Cancel. when i am clicking the edit imagebutton it goes through
if (e.Row.RowState == DataControlRowState.Edit)
{
ImageButton imageditformtype = (ImageButton)e.Row.FindControl("imgEditFormType");
imageditformtype.Visible = false;
ImageButton imageupdateformtype = (ImageButton)e.Row.FindControl("imgUpdateFormType");
imageupdateformtype.Visible = true;
ImageButton imageditcancelformtype = (ImageButton)e.Row.FindControl("imgEditCancelFormType");
imageditcancelformtype.Visible = true;

}
so the images changes to update and cancel.
But for Alternate rows the rowstate is Alternate and not goes to edit therefore the ImageButtons are not changed

pls help me out with this .

I am trying to create an Excel file with the XMLTextWriter class. I am successfully able to write the excel file with data from dataset in it. But the problem is that the string data being written in Excel is not visible fully in the cells.

I tried the option of AutoFitWidth="1", But it does not comes into effect for String data. I also got some clue for using System.Drawing.Graphics.MeasureString method. But I am not able to use it in Web project.

Can anyone guide me as to how can I fit the width of the string text in excel cell programatically.

If my mind can conceive it, and my heart can believe it, I know I can achieve it.

Stored Procedure acting a bit strange

J Liang29-May-07 15:35

Hi,

I am facing this problem which I am not sure why this is happening, so here is what happened.

I have this stored procedure

CREATE PROCEDURE dbo.IsValidLogin
(
@username varchar(50) ,
@password varchar(12) ,
@userid int=0 OUTPUT,
@userfullname varchar(50) OUTPUT
)
AS

SELECT @userid=userid, @userfullname=userfullname
FROM tb_user
WHERE useremail=@username
AND userpassword=@password

GO

Then in my ASP.NET C# code, I do this,

//Call stored procedure from database to check validity of username and password
myCommand = new SqlCommand("IsValidLogin", myConnection);
myCommand.CommandType = CommandType.StoredProcedure;

//Declare parameter for input and output of stored procedure
SqlParameter objParam1, objParam2, objParam3, objParam4;

objParam1 = myCommand.Parameters.AddWithValue("@username", SqlDbType.VarChar);
objParam2 = myCommand.Parameters.AddWithValue("@password", SqlDbType.VarChar);
objParam3 = myCommand.Parameters.AddWithValue("@userid", SqlDbType.Int);
objParam4 = myCommand.Parameters.AddWithValue("@userfullname", SqlDbType.VarChar);

objParam1.Direction = ParameterDirection.Input;
objParam2.Direction = ParameterDirection.Input;
objParam3.Direction = ParameterDirection.Output;
objParam4.Direction = ParameterDirection.Output;

objParam1.Value = uname;
objParam2.Value = upwd;

myCommand.ExecuteNonQuery();

if (objParam4.Value == System.DBNull.Value)
{
this.userid = 0;
this.userfullname = "";
}
else
{
this.userid = (int)objParam3.Value;
this.userfullname = (string)objParam4.Value;
}

This is actually a login page which I wanted to retrieve the user id and user full name, but when I login, I got this error message "System.Data.SqlClient.SqlException: Error converting data type varchar to int." It seems that it is the problem of this
"objParam4 = myCommand.Parameters.AddWithValue("@userfullname", SqlDbType.VarChar);" which is converting it to int, I did not make it to change to int but just don't understand why it wanted to convert.

Hope someone experience this before and do let me know why this is happening.

Thanks

Are you sure that your userid field can contain only integer values ? What is the datatype of that field ?

29-May-07 20:32

Hi,

Actually the userid is just an auto-increment value,so it is all interger.

Btw, I got the solution, by changing AddWithValue to Add only.

Hi
See the difference below statements

exec IsValidLogin 'username','123456','sdf'
:If you run the above statement it is throwing error 'Error converting data type varchar to int':

exec IsValidLogin @username='harini',@password='123456',@userfullname='sdf'
:No error in executing this statement:

Solution 1:
Change the order of output parameters as

@username varchar(50) ,<br />
@password varchar(12) ,        <br />
@userfullname varchar(50) OUTPUT,<br />
@userid int=0 OUTPUT

Solution 2:
Pass maximum value for parameter @userid from code-behind without changing the order of output parameters.

Try any of the above solutions and let me know.

Hope you got it.

Yes, that is a different way of getting the same error message, but I don't see the relevance?

Hi,

Thanks for the reply, I think this might work too.

I got an earlier post which I switch from AddWithValue to Add as using AddWithValue cause it to add the value and it become me adding 4 integer value.

Guffa29-May-07 19:12

This is not strange at all.

When you use the AddWithValue method to create parameters, the second argument is not the data type, but the value. Therefore you are creating four parameters with the type int (as int would be the type used to send the enum values to the database).

Use the Add method instead to specify the data type, and also specify the size of the varchar fields:

objParam1 = myCommand.Parameters.Add("@username", SqlDbType.VarChar, 50);<br />
objParam2 = myCommand.Parameters.Add("@password", SqlDbType.VarChar, 12);<br />
objParam3 = myCommand.Parameters.Add("@userid", SqlDbType.Int);<br />
objParam4 = myCommand.Parameters.Add("@userfullname", SqlDbType.VarChar, 50);

Hey,

Thanks, this way works well, didnt really understood the difference of Add and AddWithValue until now.
