problem with column style in datagrid

[thomas10001]

I have a DataGrid where I have set column styles to my column in the DataGrid.

 

When I am using the column style I cannot add a new row to the datagrid. (If I dont use any column styles it works fine to add a new row)

 

What can be wrong?

 

If I am looking at my CurrencyManager in the debugger after I have added a new row the differences are two:

 

Using column style

 

onItemChanged <undefine value>

onMetaDataChangedHandler <undefined value>

 

Without column style

 

onItemChanged {System.Window.Forms.ItemChangedEventHandler}

OnMetaDataChangedHandler {System.EventHandler}

 

Is it something with this two that the problem arises for? Or can it be something else.?

 

Is it something extra needed to bet set when adding the column style? I am just using an example in the .NET help so set the column style.

A few questions to ask yourself to try and address the problem.

1-What are you using as your datasource:- dataview, dataset/datatable

2-How are you adding the row to your datagrid

3-Have you set the databinding

That is not the problem. It is working perfect without the columnstyles.

How do you add the row, programatically or is the user entering it in the datagrid.

[thomas10001]

The user add the row to the datagrid which has an ArrayList as datasource. Then the row is added through the currencymanager.

 

If I remove all columnstyles it works fine. I have the same problem on datagrids with dataset as the datasource too.

[thomas10001]

I found the solution. Since I am using an ArrayList as datasource I had to set DataSource = null before adding the new row otherwise no visual effect. Then it has to be set to the arraylist after wards, which I already knew.

I have a similar problem with the width of data showing up on my datagrid.

I use a datatable to populate my datagrid, but the grid shows the default width per column.

Is there a way to change the width of a column and also change the alignment of each column (currently s/b right justify) ,etc.

 

thankx

Hi jahan, just use the datatablestyles and you can do all that.
