I am using a RadGrid to display stock information. The data bound is a combination of 2 views and 2 tables. This is quite an intensive query, and the data behind it changes a lot. Now, when I update a value in a single row, I have to Rebind the data to update my grid (I use UpdateValues on the item, but it has no visible effect). This is taking too long to be user-friendly. Is there a simple way to work around it, so I can just update the row which has the changed data ?
I do not think there is a way to do that because the Telerik Grid is data bound control - hence to modify its source and refresh the data in the grid UI, you will need to bind all rows.

We have a request from our designers to build tables something like this, with rows that expand to show essentially another sub-table underneath. In KendoUI documentation, this is called "Hierarchy."
We use SlickGrid v2.3 with a few additional plugins. We currently have tables with a similar row expand/collapse like this: https://mleibman.github.io/SlickGrid/examples/example5-collapsing.html . That does not allow for a completely different set of columns in the sub-table.
The question is, can this be done in SlickGrid or not?
It might be hard to do with current SlickGrid, there's no code that handles the hierarchical part itself so that would be lot of work to implement in SlickGrid. However it is implemented in Slickgrid-Universal, which is a wrapper on top of SlickGrid. You can see Example 5 and Example 6 which shows 2 types of Tree Data grids (hierarchical or parentId refs). We use it in production for a project that we have. Also note that this is not a grid within a grid, it's rather an expand/collapse the same as what you found in example5-collapsing.html, the only differences with SlickGrid is that Slickgrid-Universal has the code to deal with hierarchical data (filtering/sorting) while SlickGrid itself doesn't and also another nice to know thing is that expand/collapse is actually using data filtering behind the scene and you can see that in the total items displayed when you have the footer enabled.
Please note that I'm the author of Slickgrid-Universal and also a major contributor to SlickGrid as well
At the moment, it can't be done. In order to achieve its speed, Slickgrid enforces a fixed row height and a single scrolling canvas. It's just a different approach than used by HTML display grids.
You could put together a workaround using mutiple slickgrids or an embedded slickgrid in a group row, I suppose, but it would be messy.
One thing I have done is develop a SlickCombo, which is essentially a grid presented as a multi-column dropdown. It's a full grid and can offer editing.
That's probably as close as you'd get.
A comment: the MLeibman repo is long dead - you should be using: https://github.com/6pac/SlickGrid
I have a grid panel with about one hundred rows.
On grid's store load event a lot of calculations happen that update store rows.
Each update of store row leads to grid row refresh and DOM modifications and this leads to explorer's "Stop running this script?" message.
I'm looking for a way to improve the performance of this code.
Is there any way to suspend DOM operations for the grid in ExtJs 3 - something like suspendLayout, resumeLayout in ExtJs 4?
My design requires a checkbox as the first column in the grid and subsequent grids, however, using Hierarchy to implement those subsequent grids, the drop down arrow that kendo adds becomes the first column making the column with the checkbox template second. Is there an efficient / official way of getting around this?
I have a jqgrid that has a lot of information for each record. It's causing a lot of horizontal scrolling and I'd like to avoid that.
I thought about using a subgrid, but every example I've seen for subgrid has the sub-info collapsed and I don't really want that. I just want the 2nd row for each record to be indented a bit.
Is there a good way to handle this besides using a subgrid. The other drawback to subgrid I've found is that it wants to load secondary data on the click to expand it. I'd rather just have all of the data loaded on the initial grid load.
TIA
currenetly, I am using the telerik Radgrid control to build a grid. my grid have two levels ( mastertableview and detailtables). In detailtables, there is a gridclientselectcolumn to show a checkbox.
What i want to do is to make only one row selected at each time. That means, when I select a row in a detail table, the other one selected previously need to be deselected.
The allowrowselecting and muliplerowselect are only used to control the mastertableview. Now i need a way to control the detail tables.
Thanks
Recently I bumped into a How-to topic from the Telerik AJAX docs that may match your case or become the core of your logic, too - check it out.
