Relation between pageSize, trailingBufferZone and leadingBufferZone

[yash.kapoor]

Hi,

It is recommended to tune the pageSize, trailingBufferZone and leadingBufferZone configurations based upon the conditions pertaining in your deployed application.

If pageSize is 25, What is the trailingBufferZone and leadingBufferZone values.

Example:-

<ext:Store
                    runat="server"
                    Buffered="true"
                    PageSize="25"
                    TrailingBufferZone="What to fill in this(Value)"
                    LeadingBufferZone="What to fill in this(Value)"
                    OnReadData="Store_ReadData">

According to Ext.Net Documentation

LeadingBufferZone
When buffered, the number of extra rows to keep cached on the leading side of scrolling buffer as scrolling proceeds. A larger number means fewer replenishments from the server. Defaults to: 200

TrailingBufferZone
When buffered, the number of extra records to keep cached on the trailing side of scrolling buffer as scrolling proceeds. A larger number means fewer replenishments from the server. Defaults to: 25

Hi Raphael Saldanha,

I want to know the tuning between pagesize, leadingBufferSize and trailingBufferSize. i.e. I want to know, if pagesize is 25 so what should be the leadingBufferSize and trailingBufferSize.

Thanks for the reply!

Ok thanks for the help!

I just want to know that, how can i achieve a single ajax call at a time, just like in paging.

Now it was calling a three ajax calls at time.
