Hi,
I have a grid where all the rows are in edit mode and a column with a total in the footer of the grid. I want to automatic display the sum of the column without postback when the user enter a value in a cell. The only solution to do this seems to be to sum the column in Javascript. It is possible to do that ? Is there a grid client API to do this?
Thanks
Yvan Sigouin

Hi Yvan,
There is no "out-of-the-box" implementation of your desired functionality. Nevertheless, you can get the values of your cells on the client and sum them up in the "keypress" client event handler of your input. Please refer to this online help article on extracting key values client-side.

Hi,
Good! Now I have a grid with auto-calculate sum fields.
But I suggest to add this feature in the client API for the next release of RadGrid.
Thanks

Hello Yvan,
Thank you for the suggestion - I will forward it to our development department for further consideration. If this appears to be a common request and a feasible addition to the current client object model of the grid, you may see it included in a future version of the product.

I tried to use the code provided in the sample.
The problem I have is , I have multiple columns in my grid for which I need to display the total.
With the code provided if i update any cell the total for all the columns gets updated to the same amount.
Can you provide me some code which meets my requirements.
That is update the total in the respective column in which the cell belongs.
I have been struggling with various ways to auto update the aggregate on client side but always end up running into some kinds of issues.
Please help.

Hello newbie,
The javascript logic for updating the footer values for multiple columns will not differ if you ensure that you access the cells of the column of interest using its unique name. Please verify that and let us know if further directions/assistance is needed.

Hi newbie,
Here is the example you requested (you will find it attached to this message). Note that I added duplicate Freight column as last in the grid and attached different Blur/Focus/Load client handlers for the second set of RadNumericTextBox instances in that column.
