Setting varying height to grid rows

[Santhana Gopalan Seshasayee]

Hi -

I have data in two columns. Column 2 will have text that could exceed more than 1 line and hence is wrapped.

I would like to set varying height to the rows that have wrapped text so that the entire text is visible.

Intially, I used the following statements to autofit the row height.

// Code Start
Grid1.TableModel.RowHeights.ResizeToFit(GridRangeInfo.Rows(2, Grid1.TableModel.RowCount));
// Code End

But this makes the rows show only the first two lines of the wrapped text (the wrapped text vary from 2 to 10 lines).

Secondly, I tried to set the individual height of the rows based on certain condition using the below code.

//Code Start
Grid1.TableModel.RowHeights.SetSize(2, 100);
Grid1.TableModel.RowHeights.SetSize(3, 400);
//Code End

Here the row 2 is set to a height of 100 and row 3 is set to a height of 400. The moment the second statement is executed, the row 2 also is set to a height of 400.

That is, all the rows in the grid are set to the largest height among the rows.

Can someone explain why is happening? Or am I missing to set any other property?

Thanks

Hi Santhana Gopalan,

Thank you for posting query to us.

By default, the GridGroupingControl does not support rows with individualized rowheights. To get this support, you need to add a custom GridEngine as in the ResizableRows browser sample( \Essential Studio\6.1.0.34\windows\Grid.Grouping.Windows\Samples\FeatureSamples\ResizableRows ). The ResizableRows browser sample also shows you how to implement the IGridRowHeight interface and its routines for getting and setting row heights for elements.

Please let me know if you have any questions.

Regards,
Jisha

Hi Jisha -

Thanks for the inputs. Can you please provide me the exact URL with which I can get the sample on ResizableRows that you've mentioned in your response. Or please send the sample zip file to my email id.

Appreciate your quick response.

Thanks

Hi Santhana Gopalan,

you can also access the sample from the dashboard in Grid.Grouping.Windows --> FeatureSamples --> ResizableRows

Also I have uploaded the sample here:
ResizableRows.zip

Thank you for using Syncfusion products.

Hi, looking to use your example to resize the row that the mouse is hovering over, what would be the best way to do that?

Thanks

Also, the zip file you posted appears to be invalid.

Ok, got individual resizing of rows to work with a mouse over.

New question though, if I set the row heights on several rows the screen updates after each SetRange, is there a way to suspend the updates so they all redraw together? GGC.SuspendUpdates() ResumeUpdates() doesn't help.

Thanks

Hi John,

Thank you for posting query to us.It is not possible to use gridGroupingControl.ResumeUpdates() and gridGroupingControl.SuspendUpdates().

Please provide with more information, so that we can clarify your doubt.
