Assign a value to DropDownList on the page

Assign a value to ComboBox in winform. In WinForm, ComboBox obtains the SelectedValue supplement of the bound object set.

On the page, assign a value to DropDownList as follows:

DpType. SelectedIndex = dpType. Items. IndexOf (dpType. Items. FindByText (m_TradeReport.R_CateName ));


DpType. SelectedIndex = dpType. Items. IndexOf (dpType. Items. FindByValue (m_TradeReport.R_CateID ));

These two methods can avoid the following situations where values cannot be set:

DpType. SelectedValue = Convert. ToString (m_TradeReport.R_CateID );

Obtain the selected value for DropDownList:

M_TradeReport.R_CateID = SQLParser. IntParse (dpType. SelectedValue );
M_TradeReport.R_CateName = SQLParser. StringParse (dpType. SelectedItem. Text );
Catch {}


M_TradeReport.R_CateID = SQLParser. IntParse (Request [dpType. UniqueID]);
