    Hi all,

    i am in project, now i am in critical phase..

    my scenario : Radgrid needs to refresh at regular interval, but not whole grid, it should refresh particular columns.

     In Details:


    B1 is buyer1

    B2 is buyer2 and so on.

    S is seller.

    S(Seller) wants to sell a product through online and he can Negotiate Rate to different Buyer(B1,B2 and so on) at same time.

    i am using grid control to display Buyers details to seller

    Grid Contain:

    Sellers's Grid
    Buyer Name*, Product Name*, Product's First Rate*, Seller's Rate**, Buyer Rate*$
    Buyer's Grid
    Seller Name*, Product Name*, Product's First Rate*, ​Buyer's Rate**, Seller Rate*$​

    * --> Label

    ** --> Textbox

    $ --> Columns needs to refresh

    Seller will entry his rate in Seller's Rate in Grid, after entering the rate immediately it should be display in Buyers Gird(Seller Rate Column).

    i can able to fetch the rate in grid, using timer control. the problem is, it refresh whole grid.

    while seller trying to enter rate in grid, due to refresh of grid, Seller not able to enter rate at the time of timer control triggers.


    it is possible to refresh particular column in grid without affecting other columns. 

    Most importantly, it is possible refresh the Buyer Rate column and enter the value in Seller's Rate column at same time in Seller's Grid.


    It you have solution,help me

     Thanks in Advance.

    Please note that RadGrid is a complex control and needs to be updated as a whole. It is not possible to update only some of the columns. When rebinding the grid, all data will be refreshed.

    In order to prevent the control from updating while the user edits a value you can temporarily disable the Timer control. The following stackoverflow thread describes how you can stop and start a Timer.
