मैं कर रहा हूँ एक सॉफ्टवेयर में मदद करने के लिए मुझे काम पर. यह पढ़ता है दो एक्सेल (xlsx) फ़ाइलों और कुछ जानकारी मिल से उन्हें. तो यह जानकारी डाल में से एक में दो datagridviews या दोनों में datagridviews.
तो मैं एक संख्या है, मैं की जरूरत है कि दिखाने के लिए जब मैं प्रिंट datagridviews. मुद्रण पूर्वावलोकन में सब है बिल्कुल के रूप में मैं करना चाहते हैं लेकिन जब मुद्रण कागज पर इसे हटा (या याद नहीं है) सब कुछ के बारे में पहली datagridview और मैं कुछ भी प्रिंट के साथ यह और शुरू से 2 datagridview.
यहाँ यह कैसे पता चलता मुद्रण पूर्वावलोकन में:
लेकिन जब मैं इसे कागज पर मुद्रित मैं इस तरह
क्यों पहली datagridview चला गया कागज पर लेकिन अगर मैं इसे प्रिंट पीडीएफ माइक्रोसॉफ्ट से प्रिंट पीडीएफ के लिए मैं पीडीएफ गया है कि वास्तव में पूर्वावलोकन के रूप में.
समस्या केवल जब कागज पर मुद्रण.
यहाँ है मेरे कोड मुद्रण https://pastebin.com/6ZF2FevZ
