I just tried this version downloaded from the forum and it works as expected.
Do you have a screenshot ? Or post your project as a zip file.

Version 1.13 is an 'old' version the latest one is version 1.22, you find it here.

Best regards.

Add Dim Record(Cols.Length) As String in the code below line 92:

        Else If i = 2 Then '-------------------------------------> 'Checking Recordset DataType and based on that set columnwidth
            For J = 0 To Cols.Length - 1
                If Cols(J) = 135 Then
                    cWidth(J)  = 80dip
                Else If Cols(J) =  200 Then
                    cWidth(J)  = 120dip
                Else
                    cWidth(J)  = 65dip
                End If
            Next
        Else
            Dim Record(Cols.Length) As String
            For J = 0 To Cols.Length - 1 '----------------------------------> ' Adding Rows
                Record(J) = Cols(J)
            Next
            Table1.AddRow(Record)
        End If
    Next
    Table1.SetColumnsWidths(cWidth)

Thanks for your quick reply,Now its working fine now.

There is one more issue I am facing that, When I load 20 Columns Data in Table it works fine but the same time when I load 4 Columns Data ,it shows as 4 column & Previous 16 Column in Table (not able to clear previous column after applying table1.clearAll)

Table1.Initialize(Me, "Table1", Cols(i),0,True)
Table1.AddToActivity(PnlRight, 0, 0dip, PnlRight.Width, PnlRight.Height)
Table1.ClearAll

Where Cols(i) --------> Dynamic No of Column

In your case, when you call LoadGrid a second time you initialize a second Table instance overlapping the first one and as the second has less columns you see both.
I added the RemoveView method to the Table class so you can remove the previous table and initialize the new one.
Attached your modified project. I added three buttons to show the difference.
You don't need the Table1.ClearAll routine.

Best regards.

EDIT removed the project, new version in post #9.

Can u update Footer in Table (This is my sugesstion),So that we can easily summary for numeric column

It did exist but there was a problem with the StatusLine update.
You can disable the autofill of the StatusLine with Table1.StatusLineAutoFill = False.
And update the line with Table1.StatusLine = "Test line".
Attached your modified project.
Use the new Table class file in this post.

Best regards.

get Error as

Compiling code. Error
Error compiling program.
Error description: Unknown member: statuslineautofill
Occurred on line: 96
Table1.StatusLineAutoFill = False
Word: statuslineautofill

 

[klaus]

I downloaded the project back from post #9 to make sure that we have the same.
Works OK here so I don't know what you have done.

Best regards.

Sorry Klaus,Now its working fine,I have few more request to add functionalities in Table Class

1.Set Alignment for each column such as SetAligmment(left,right,left,center)
2.Need Summary for Each column in Footer.
3.Need Row freeze

 

[klaus]

1. This needs some more time to add.
2. What do you mean with Summary ?
3. What do yu mean with freeze a row ?

I'm afraid that points 2 and 3 will be too specialized.

Best regards.

 

[junaidahmed]

2. What do you mean with Summary ?
Answer : All Numeric Column should be display as "Sum" in Footer of a table.

3. What do yu mean with freeze a row ? -----------> Free a Column not as freeze a row

Answer : I have to fixed a first column,when horizontal scrolling
(i.e) First Column Should not be scroll it should be fixed.

Hope its clear for you

2. This is too specialized because valid only for numeric columns.
You could manage this with the StatusLine property.
Or why not add a 'special' row at the end of the table ?

3. This would need a very deep modification of the class. No time for this.
I had done this with two ScrollViews in the GPSExample program in the GPSPaths module.
The source code is in the User's Guide SourceCode folder.

Best regards.

Is it possoble to update "Set Alignment for each column such as SetAligmment(left,right,left,center)" as discuss before.Because its most urgent for me

 

[klaus]

Attached you find your project with a new method in the Table class:
SetCellAllignments(Alignments)
