这是我的视图状态的代码。 但它只存储一个值。我需要的是它将选定的多个值保留在复选框中。 此方法是在分页情况的网格视图中保留/保持复选框的值。
public void chkAssignee_OnCheckedChanged(object sender, EventArgs e)
{
CheckBox selectBox = (CheckBox)sender;
GridViewRow myRow = (GridViewRow)selectBox.Parent.Parent; // the row
GridView myGrid = (GridView)myRow.Parent.Parent; // the gridview
string ID = myGrid.DataKeys[myRow.RowIndex].Value.ToString();
GridViewRow rowSelect = (GridViewRow)selectBox.Parent.Parent;
int a = rowSelect.RowIndex;
ViewState["id"] = ID;
}
尝试关注以下代码可能会对您有所帮助。
public void chkAssignee_OnCheckedChanged(object sender, EventArgs e)
{
CheckBox selectBox = (CheckBox)sender;
GridViewRow myRow = (GridViewRow)selectBox.Parent.Parent; // the row
GridView myGrid = (GridView)myRow.Parent.Parent; // the gridview
string ID = myGrid.DataKeys[myRow.RowIndex].Value.ToString();
GridViewRow rowSelect = (GridViewRow)selectBox.Parent.Parent;
int a = rowSelect.RowIndex;
ArrayList SelecterdRowIndices=new ArrayList();
if(ViewState["SelectedRowIndices"]!=null)
{
SelecterdRowIndices=(ArrayList)ViewState["SelectedRowIndices"];
bool flag=false;
foreach (int i in SelecterdRowIndices)
{
if(i==Convert.ToInt32(ID))
{
flag=true;
break;
}
}
if(!flag)
{
SelecterdRowIndices.Add(ID);
}
}
else
{
SelecterdRowIndices.Add(ID);
}
ViewState["SelectedRowIndices"] = SelecterdRowIndices;
}
