int type causes error

int type causes error

int type causes error

I have this code which causes an error.

// Edit

if (e.CommandName == "Edit")


// Get the item

RepeaterItem Item = ((RepeaterItem)((Button)e.CommandSource).NamingContainer);

// Get buttons and repeater

Button savebtn = (Button)(Item.FindControl("btnSave"));

Button editbtn = (Button)(Item.FindControl("btnEdit"));

Repeater rFields = (Repeater)(Item.FindControl("repFields"));

// Store markers

((HiddenField)Item.FindControl("prevEnabled")).Value = btnPreviousRec.Enabled ? "1" : "0";

((HiddenField)Item.FindControl("nextEnabled")).Value = btnNextRec.Enabled ? "1" : "0";

// Enable my fields

foreach (RepeaterItem RI in rFields.Items)


// Get data type

HiddenField dt = (HiddenField)(RI.FindControl("hdnDBDataType"));

// Set controls

if (RI.FindControl("chkSetting").Visible) ((CheckBox)RI.FindControl("chkSetting")).Enabled = true;

if (RI.FindControl("ddlSetting").Visible) ((DropDownList)RI.FindControl("ddlSetting")).Enabled = true;

if (RI.FindControl("txtSetting").Visible)


((TextBox)RI.FindControl("txtSetting")).Enabled = true;

// Check my data type

if (dt.Value.ToLower().Substring(0, 4).Equals("date")) ((CalendarExtender)RI.FindControl("extDateTime")).Enabled = true;




This is the line which causes the erro:
dt.Value.ToLower().Substring(0, 4).Equals("date")
It works fine if dt.Value different to int, e.g. "varchar" or "datetime"
Is this a good fix ?
if(dt.Value != "int" && dt.Value.ToLower().Substring(0, 4).Equals("date"))
