Please help me to solve this
When I place a textbox
<
asp:TextBoxonkeypress="checkCompany()"ID="txtSortName"onkeydown="goToNext()"TabIndex="13"runat="server"onchange="SetSaveFlag()"MaxLength="15"></asp:TextBox>and give onkeypress, onkeydown, onchange etc like the above one I am getting errors like
1. Attribute 'onkeypress' is not a valid attribute of element 'TextBox'.
2. Attribute 'onkeydown' is not a valid attribute of element 'TextBox'.
3. Attribute 'onchange' is not a valid attribute of element 'TextBox'.
Can you suggest any alternate ways?
