TextBox and DropDownList in Datagrid Edit mode

Hi,

I am very new to ASP.NET and web programming in general. I have one issue. I have a Datagrid object with Edit template. In one Datagrid row, I have 1 DropdownList, 1 textbox and 1 readonly textbox in Edit mode. I have written OnTextChanged event handler for text box and OnSelectionIndexChanged event handler for dropdownlist. Whenever a text is changed in writable textbox or a selection is changed in DropDownList, I perform calculations and put the result in readonly textbox. I have to tab/click out of TextBox For the OnTextChanged event to be fired. So, when I click on the "dropdown arrow" or DropDownList while editing the TextBox contents, my window goes totally blank. I am calling this DataGrid form from another .aspx page in an IFrame. Can anyone please tell me why my window goes blank ?

Thanks a bunch in advance.I noticed your post went unanswered. Have you resolved this issue?

I have a Datagrid object with Edit template. In one Datagrid row, I have 1
DropdownList, 1 textbox and 1 readonly textbox in Edit mode. I have written
OnTextChanged event handler for text box and OnSelectionIndexChanged event
handler for dropdownlist. Whenever a text is changed in writable textbox or
a selection is changed in DropDownList, I perform calculations and put the
result in readonly textbox. I have to tab/click out of TextBox For the
OnTextChanged event to be fired. So, when I click on the "dropdown arrow" or
DropDownList while editing the TextBox contents, my window goes totally
blank. I am calling this DataGrid form from another .aspx page in an IFrame.
Can anyone please tell me why my window goes blank ?

Hi

Thanks for looking. No, this issue is not resolved. This definitely seems to be a bug in ASP.NET as it happens only if Datagrid page is within a frame. Otherwise it works just fine. Currently I have done a temporary solution of calling the ASP.NET page from asp as window.open instead of in a frame in a Modal dialog box. Let me know if I am missing something

Thank
