Hi Ramana,

I am not able to reproduce the issue that you mentioned here. I have created a simple Gridgrouping sample with two datatable. During the page load the first table is binded. Then in button click I have binded the next tabel. Here it works.

Please refer the sample in the below link which illustrates the above:

http://websamples.syncfusion.com//samples/Grid.Windows/F-73433/main.htm

Please have a look at the above sample and if still the issue exists, could you please try reproducing it in the above sample and send us the modified sample so that we could sort out the cause of the issue and provide you a solution?


Regards,
G.Yavana

For GridGroupingcontrol :
In the Form I am retrieving The data from database to dataSet, then i am assigning the data to grid like:
gridgroupingcontrol1.DataSource=ds.Tables[0];
here I am disabling the some fields like
gridgropuingcontrol1.visiblecolumns.Remove("Columnname");

after showing the form
I am clicking the Button in this clickevent

once again I am retrieve the data from different table to dataset
then i am assigning like :
gridgroupingcontrol1.DataSource=ds.Tables[0];
in this
the columns are showing the first table columns only.

Hi Ramana,

Thanks for your update.

If you trying to rebind a datasource, you have to reset the DataSource before rebinding it. You can follow the below code snippets for rebinding a DataSource in GridGroupingControl.

Below is the code snippet:


this.gridGroupingControl1.DataSource = null;
this.gridGroupingControl1.DataMember = null;
this.gridGroupingControl1.ResetTableDescriptor();
this.gridGroupingControl1.TableDescriptor.Relations.Clear();
this.gridGroupingControl1.DataSource = ds.Tables[1];
this.gridGroupingControl1.Reinitialize();
this.gridGroupingControl1.Refresh();


Here is the sample:

Please have a look into the above sample and let me know if you need any further assistance.

Subhasheela R
