gridDataBoundGrid - using as a databound list box

[Badri Rajani Kanth]

Hi,

I want to create a control from gridDataBoundGrid, which will give me similer functionality like a list box(same properties and events). This is because, when no of datarows are more(50K), I observed grid to be faster than listbox.

Do we have any such control in place?
Or just tell me how to remove all columns headers from gridDataBoundGrid. I will keep asking if i get any more doubts in this custom control creation process..thank you in advance.

Hi Badri,

You can use a GridListControl like a list box. Refer the sample in Syncfusion\Essential Studio\3.3.0.0\windows\Grid.Windows\Samples\Quick Start\GridListControlSample\ to know about GridListControl. By setting this.gridListControl1.ShowColumnHeader = false; and the this.gridListControl1.MultiColumn = false; you can make it similar like a list box.

To hide the headers in the GridDataBoundGrid, set
this.gridDataBoundGrid1.Model.Cols.Hidden[0] = true;
this.gridDataBoundGrid1.Model.Rows.Hidden[0] = true;

Best Regards,
Calvin.

Cool,

I am actually working with that.
The one main problem i have with that control is NOT having SelectedItems collection. As my user can select any no of items, i need to have a SelectedItems collection which can me Count and All selected objects. Any input plz?

Hi,

In addition, we dont have SelectedIndices also.
I am using Grid.Selections.Count for SelectedItems.Count. But, when selected items are many, i have problems..

Hi, Ideally I want to store and retrieve daraRows/dataRowViews and retrieve the same from GridListControl. If i just go by text property, i can have many duplicates.

Hi, I am trying with below code. Is this OK? foreach(Syncfusion.Windows.Forms.Grid.GridRangeInfo range in list) { for(int i = range.Top; i <= range.Bottom; i++) { DataRowView dataRowView = this.gridListControl1.Items[i-1] as DataRowView; string firstName = dataRowView.Row["FirstName"].ToString(); //DisplayMember string lastName = dataRowView.Row["LastName"].ToString(); //ValueMember System.Diagnostics.Debug.WriteLine(firstName + ":" + lastName); } } .. Plz confirm.. Rgds Rajani Kanth >Hi, >Ideally I want to store and retrieve daraRows/dataRowViews and retrieve the same from GridListControl.

Hi Badri,

Yes, you can retrieve the selected rows as mentioned and you can also add a row to the grid by just adding it to the Table. Below is the code snippet.

DataTable dt = (DataTable)this.gridListControl1.DataSource;
DataRow dr = dt.NewRow();
dr[0]="John";
dr[1]="Knox";
dt.Rows.Add(dr);
