Hello,
I would like to inform you that on setting the Column.Width to 'Auto’, the respective Column’s Width is set to the default Width which is neither based upon the Column Header or the Cell Content of that Column in C1FlexGrid.
On the other hand, the same property if set to 'Auto’ in C1DataGrid sets the width of the column as determined by the content of the cells in the columns.
Please refer to the following documentation links where the same has been mentioned :
Also, the code provided above by @Deepak could be used to resize the Column’s Width as per the Cell Content in the C1FlexGrid’s Column.
The above suggested code works correctly for number of the rows as large as 10000 with the latest Build of C1Silverlight : 5.0.20133.380 available at :
prerelease.componentone.com/hotfixes/silverlight/C1Silverlight_5_5.0.20133.380_RC1.msi
If the issues persists with the latest build too then kindly elaborate more on what exactly is the issue faced, if possible, by sharing a stripped down sample application of your code replicating the issue and a video demonstrating the current behaviour at your end. This would help us in providing you with further appropriate assistance.
Regards,
Reema
