Hatam\u0131z\u0131n g\u00f6rsel hali;

\nHatam\u0131za bakarsak e\u011fer CellType \u00f6zelli\u011finin null olmas\u0131ndan bahsetmi\u015f. Peki, hemen halledelim o halde…

\nHoppp balaa! Ulan hem CellType \u00f6zelli\u011fi null olamaz diyorsun hem de ilgili \u00f6zelli\u011fe de\u011fer set ettirmiyorsun!<\/p>\n

Tabi ki de \u00f6\u011frencinin yan\u0131nda bu sinir bozucu hataya daha a\u011f\u0131r ithamlarda bulunmu\u015f olabilirim.<\/p>\n

Onca arama taraman\u0131n ard\u0131ndan hatan\u0131n \u00e7\u00f6z\u00fcm\u00fcn\u00fc CellTemplate \u00f6zelli\u011finde buldum. Me\u011fer, olu\u015fturdu\u011fumuz kolonun h\u00fccre elementini belirtmemiz yeterliymi\u015f.<\/p>\n

\r\n            DataGridViewColumn kolon = new DataGridViewColumn();\r\n\r\n            kolon.CellTemplate = new DataGridViewComboBoxCell();\r\n            kolon.HeaderText = "\u00d6rnek Kolon";\r\n            kolon.Width = 150;\r\n            kolon.Name = "kolon";\r\n\r\n            dgvPersoneller.Columns.Add(kolon);\r\n<\/pre>\n\u00d6rnek olarak yukar\u0131daki kod blo\u011funu inceleyebilirsiniz. G\u00f6rd\u00fc\u011f\u00fcn\u00fcz gibi olu\u015fturulan bu kolon bir ComboBox t\u00fcr\u00fcnden h\u00fccre olarak ayarlanm\u0131\u015ft\u0131r.<\/p>\n
Bu ufak bilgiyi bir daha unutmamak i\u00e7in buraya not alm\u0131\u015f olal\u0131m…<\/p>\n
\u0130yi \u00e7al\u0131\u015fmalar dilerim…<\/p>\n","protected":false},"excerpt":{"rendered":"
