Unable to invoke protected method of DataGrid in Paint method

[Kais4U]

Hi Martin, Where do we need to define "InvokeRequired" variable? Also i have override the paint method which has 7 parameters. Is that an issue? Please guide me if am wrong. I want to make this work. Regards, Kais

Hi Kais, InvokeRequired is a member of System.Windows.Forms.Control. You can have as much parameters as you whant, as long as your delagates has the same. private delegate void xxxDelegate(..., ..., ..., ...); Hope that helps you! All the best, Martin

Hi Martin, Thanks for your prompt reply. I added the peice of your code in my customized datagrid class which inherits from DataGrid. Now it throws me the following errors The name '_OnPaint' does not exist in the class or namespace CustomControl.CustomGrid.CustomDataGrid' CustomControl.CustomGrid.CustomDataGrid.OnPaintDelegate' denotes a 'class' which is not valid in the given context This might be a stupid thing i am asking. The delegate needs to be wrapped with the method. Where do i need to assign the method for it? Thanks in advance Regards, Kais

Sorry, Was my mistake! private delegate void get_DataGridRowsDelegate(..., ..., ..., ...); protected override void get_DataGridRows(..., ..., ..., ...) { if(InvokeRequired) { get_DataGridRowsDelegate(new get_DataGridRowsDelegate(get_DataGridRows), new object [] { ..., ..., ..., ..., } ); return; } //Your code } The method has to be your get_DataGridRows Method you asked for. With all the parameters you had. If its not working, please post the code here! Martin -- modified at 8:08 Monday 3rd July, 2006

Was a little confused before. I mixed my code to yours and forgot your actual question.

Martin, Thats ok. But get_DataGridRows method is not available for override. How will this work? Regards, Kais

In your case, you can create Method like you had before. private void get_DataGridRows(...... ; just insert code in your Method. Martin Please give me feedback, if it works.
