serializing a GridModel used as part of a datastructure

[Administrator]

In the attached example I use a GridModel as a scratchpad structure. Unless I have copied values

into this GridModel, I am unable to save and load the data structure successfully. Is there a way to

do so? In the real app, the GridModel may be empty because there are a lot of preliminary steps

which the user must complete before reaching the step where the scratchpad is used. This could

take days or weeks. Hence, saving at intermediate stages becomes a necessity.

Hi Jan,

 Thank you for your interest in Syncfusion products.

 You can serialize the GridModel directly to binary format using the SaveBinary() and so you can use the following way to achieve the desired behavior instead of serializing using BinaryFormatter and Stream.

 // Serialize

if (dr == System.Windows.Forms.DialogResult.OK)

            {

                dataStructure.Textbox1Text = textBox1.Text;

                dataStructure.Textbox2Text = textBox2.Text;

                this.gridControl1.Model.SaveBinary(saveFileDlg.FileName);

            }

 

//Deserialize

if (dr == System.Windows.Forms.DialogResult.OK)

            {

                this.gridControl1.Model = GridModel.LoadBinary(openFileDlg.FileName);

                this.gridControl1.Refresh();

                textBox1.Text = dataStructure.Textbox1Text;

                textBox2.Text = dataStructure.Textbox2Text;

            }

Your approach saves the grid model but does not save the data structure. I wish to save a data structure, one element of which is a grid model, as a single file. Using your approach would require saving the data structure as 2 files (1 file for the 'non-grid' data elements and another for the grid model).

Hi Jan,

Hi Jan,

It is not possible to save the GridModel like in your sample, only LoadBinary, LoadSoap can serialize the GridModel without any null refernce exceptions. 

So it would be better if you serialize the Grid and the datastructure in the previous approach.
