GridGrouping Control and Scroll Bars

[Rekha Mallavarapu]

Hi,

I am using the GridGrouping control in which the number of columns are not fixed. There are close to 200 different possibilities. I am binding the GridGrouping control dynamically with a stored procedure thru a datatable. There are columns ranging from 5 to 20 columns for the grid. I am not using any paging either. Also, the GridGrouping control is inside a callback Panel and there are other controls inside the panel.

The issue I have is the scroll bars for the GridGrouping control. I want the grid to fit (width wise) inside a tag. When the data is not binded to the grid the table fits the screen perfectly but when there are more columns then I have a scroll bar on my screen not on the grid.

- I don't want a scroll bar on the screen but would be nice to show the scroll bar on the grid. Any suggetions?

- Also, Is it possible to fix the height also without paging?

Anu help would be great!!

Thanks!!

Hi Rekha,

My Sincere apologize for this time delay.

You can enable a scroll bar for the GridGroupingControl by setting the custom width/Height option. Please have a look at the below code snippet.

//Sets the Width for GridGroupingControl
this.GridGroupingControl1.Width = 200;
//Sets the height for GridGroupingControl
this.GridGroupingControl1.Height = 200;

Let us know if you have any other queries.

Thanks for using Syncfusion products.

Hi Gokulkumar,

I already tried setting the height and width property. Here are the issues:

- When I use the vertical scrollbar it is very slow.

- I get this error: Microsoft JScript runtime error: 'runtimeStyle' is null or not an object in the SF_TableScrollerObject.ScrollRowToTop = function(newRowIndex).

Any ideas??

Thanks!!

Hi Rekha,

We couldn't able to reproduce the issue as you mentioned. Unlike you mentioned, Custome height and Width option doesn't throws any Javascript error and Verticall scroll bar doesn't make such a performance difference. I have tried the verticall scrollbar intially with 250 records in the GridGroupingControl. Attached is the sample in which we have tried to reproduce the issue.

I am having a very similar problem to Rekha. Was a solution ever found? I downloaded the example posted by Gokulkumar, but it doesn't seem to fit the problem that Rekha was having, or that I am having. I believe the problem lies in the high number of columns. I am creating a grid with 50 columns across, and 184 rows. When I set the height/width, and then try to scroll across the bottom, it hangs my page. Is this the same problem as you Rekha?

Thanks, Kathy

Hi Kathy,

Sorry for the delayed response.

Rekha's problem was having scroll bars while setting the Height and Width for GGC. That was clearly explained by GokulKumar in his previous update. And also I tried having scroll bars with large number of rows and columns(50 and 184), but still I am not able to reproduce the issue. When I scroll the scroll bar my page didn't get hang as you said.

Please refer the video clip from the below link which explains you clearly:

Please let me know if you have any other concerns.

This is absolutely a known issue with scrolling and IE 7. They issued a patch today, and I've applied it, but I still don't see an improvement in performance at all. Have you tried the Nov.13 patch? And did it improve performance for you? We're desperately searching for answers.

Thanks,
James
