Hi Ravi,

Thanks for the update.
In 4.3 version Button Edit Embedded text box uses windows form textbox control . In the Essential Studio latest version the Embedded textBox is changed to Syncfusion TextBoxExt control. Please change the BorderStyle to None and let me know if it is solve the issue.

Best regards,
Poly

Thanks Poly, it works. Is TextBoxExt control internally uses any border style. Do i need to add any extra code to make things to work. Because by default values in the Button edit control are not populating in v5.1. Following is the code which use to work perfectly with v4.3.

this.lookupBT = new Syncfusion.Windows.Forms.Tools.ButtonEditChildButton();
//
// lookupBT
//
this.lookupBT.ButtonAlign = Syncfusion.Windows.Forms.Tools.ButtonAlignment.Right;
this.lookupBT.ButtonEditParent = this;
this.lookupBT.ButtonType = Syncfusion.Windows.Forms.Tools.ButtonTypes.Browse;
this.lookupBT.FlatStyle = System.Windows.Forms.FlatStyle.Flat;
this.lookupBT.Location = new System.Drawing.Point(100, 0);
this.lookupBT.Name = "lookupBT";
this.lookupBT.PreferredWidth = 24;
this.lookupBT.Size = new System.Drawing.Size(16, 22);
this.lookupBT.TabIndex = 1;
this.lookupBT.TabStop = true;
//
// customerLF
//
this.Buttons.Add(this.lookupBT);
this.Controls.Add(this.lookupBT);
this.Location = new System.Drawing.Point(120, 40);
this.Name = "customerLF";
this.ParentContainer = null;
this.SelectionLength = 0;
this.SelectionStart = 0;
this.ShowTextBox = true;
this.Size = new System.Drawing.Size(216, 22);
this.TabIndex = 1;
this.TextAlign = System.Windows.Forms.HorizontalAlignment.Left;
this.TextBox.AutoSize = false;
this.TextBox.BorderStyle = System.Windows.Forms.BorderStyle.None; //Modified as you suggested.
this.TextBox.Location = new System.Drawing.Point(1, 2);
this.TextBox.Name = "";
this.TextBox.Size = new System.Drawing.Size(198, 18);
this.TextBox.TabIndex = 0;


Regards,
Ravi.

Hi Ravi,

ButtonEdit.TextBoxExt control is not using any BorderStyle internally. When ButtonEdit control is used, it is default to set TextBoxExt.BorderStyle = BordeStyle.None. Could you please provide us more details about the issue?

I have customized the ButtonEdit control, even I could see the default values in the TextBoxExt of the ButtonEdit control. Could you please modify the sample below to reproduce the issue as you mentioned?
